This question more often visits those who are associated with the construction, repair or arrangement of country sites, but it also happens that it is necessary to look for an answer on him. In our article we will try to help you with this, we will tell not only about the formulas themselves and calculations, but let's talk a little about the concrete rings themselves.

The pit under the well makes after its final design

Rings are reinforced concrete

Reinforced concrete rings are special designs for the device of wells of different calibers, which are most often used on external networks of water supply and drainage.

The production of standard products is performed in the factory conditions from high-quality concrete in strict observance of the GOST "Reinforced concrete plumbing structures".

The process of production of the rings from concrete does not represent a special complexity, for this we need:

  • Reinforced steel with a diameter of up to 10 mm.
  • High quality concrete.
  • Form for casting.

Reinforced concrete products for the wells of the wells are produced standard dimensions with marking reflecting the purpose of the ring and its size. We will tell about the varieties just below.

As for the price of each particular product is calculated, then it is necessary to understand how many cubes in the concrete ring, actually, the more, the cost above.

Calculation of reinforced concrete rings

But since there are many different options in the construction market, take, for example, the reference ring of KO 6 - the volume of concrete products is calculated as:

  • To begin with, we need to record the parameters (dimensions), in this case they will be equal to the following indicators - 840 x 580 x 70 mm.
  • Calculate the area of \u200b\u200bthe larger diameter circle according to the formula - ¼ P d2 \u003d 1/4 x 3.14 x (0.84 x 0.84) \u003d 0.553896 m2. Where n \u003d 3.14, and D is an outer diameter (in our case 840 mm). We translate all to meters.
  • Now, in the same formula, calculate the area of \u200b\u200bthe circle with the inner diameter - ¼ x 3.14 x (0,58 x 0.58) \u003d 0.264074 m2.
  • We learn from the area of \u200b\u200bthe product itself, for this you need from the area of \u200b\u200bthe circle with the outer diameter of the subtraction area with an inner diameter of 0.553896 - 0.264074 \u003d 0.289822 m2.
  • Multiplying the area to the height, we learn its volume - 0.289822 x 0.07 \u003d 0.02028754 m3.

So, on the ring of reference to 6, we calculated the volume of concrete, as you see, there is nothing difficult in this, the main thing is to know the formula and parameters of the product. However, the calculations are always easier to produce, rather than erect the well with their own hands, there is a special technique.


At a minimum, a crane is required, capable of lifting the cargo weighing in halfthone or even a ton (in the photo)

Varieties of reinforced concrete products for wells

We give the parameters of all types of produced rings for clarity (parameters will be described in the following order - height, wall thickness, inner diameter and weight):

The figure shows important parameters that will help make calculations.

Note! Marking COP Means the following - wall ring.

  • KS-7-1, 10 cm, 8 cm, 70 cm, 46 kg.
  • Ks-7-1,5; 15 cm, 8 cm, 70 cm, 68 kg.
  • KS-7-3, 30 cm, 8 cm, 70 cm, 140 kg.
  • KS-7-5, 50 cm, 8 cm, 70 cm, 230 kg.
  • KS-7-6, 60 cm, 8 cm, 70 cm, 250 kg.
  • KS-7-9, 90 cm, 8 cm, 70 cm, 410 kg.

Products with small height are called Dobly

  • KS-7-10, 100 cm, 8 cm, 70 cm, 457 kg.
  • KS-10-5, 50 cm, 8 cm, 100 cm, 320 kg.
  • KS-10-6, 60 cm, 8 cm, 100 cm, 340 kg.
  • KS-10-9, 90 cm, 8 cm, 100 cm, 640 kg.
  • KS-12-10, 100 cm, 8 cm, 120 cm, 1050 kg.
  • KS-15-6, 60 cm, 9 cm, 150 cm, 900 kg.
  • KS-15-9, 90 cm, 9 cm, 150 cm, 1350 kg.
  • KS-20-6, 60 cm, 10 cm, 200 cm, 1550 kg.
  • KS-20-9, 90 cm, 10 cm, 200 cm, 2300 kg.

A wide variety of rings allows you to easily equip the well of the desired dimension

Pay attention to the presence of reinforced ears in products weighing more than 100 kilograms.

The product, marked, for example, KS-10-6 is called a completely ring ring with dimensions:

  • Height-60 cm.
  • Internal diameter-100 cm.

There are products and with the Marking of KO (Ring Support), these products are found in the following version:

  • KO-6, height-7 cm, inner diameter - 58 cm, outer diameter - 84 cm, weight - 60 kg.

Another modification is a lining under the Luke of the Wells (ring to 1a whose concrete volume is calculated by the parameters below):

  • K - 1A, height -18 cm, the inner diameter is 58 cm, the outer diameter is 100 cm, the mass is 160 kg.

PP marking means - slab overlap

Dobly products allow you to more accurately adjust the height of the well, in some cases leveling in the level of the ground, in others - making them more noticeable. Installation of lining concrete elements on the slab coating the well will help raise the hatch above its surface.

This is eliminated:

  • Pleep the rain and melt waters in the well.
  • Driving vehicles on Luke, if the well is located under the roadway.
  • Flooding the hatch itself.

One of the important parameters of this product is the volume of the concrete ring - 1 meter cubic, it is a unit of measurement of all similar calculations.

Tip! Often, it can stumble upon ads for the sale of used concrete products, including wall supports for the well, our advice to you before buying, read the goods. In particular, inspect the inner walls on which irregularities and different shades of concrete can be seen (the cracks of unscrupulous vendors can be seal).

Ring volume: 7 advantages of reinforced concrete

You should choose a concrete ring depending on the purposes for which it will apply a properly equipped sewage system - a pledge of full comfort. Even on a small summer cottage, you can use all the benefits of civilization, equipping on the plot of a cesspool from concrete rings of different diameters.

Reinforced concrete rings are widely used to build a sewer system - viewing wells or cesspools. The use of rings is considered the easiest and most convenient way to arrange the sewage system.

Rings are made of reinforcement and concrete, they are very durable and used mainly for durable work.

When choosing a rings for a cesspool, it is worth considering the number of people living in the house

A sewer system equipped with zhb-rings is reliably protected from various weather conditions and protects groundwater from sewer leakage.

Two types of rings can be distinguished - the Eurocolt with the lock and ordinary reinforced concrete rings. The second type of rings is connected between cement mortar and iron brackets.

Advantages of using zhb rings:

  • Long service life of the product;
  • Do not miss moisture;
  • Simplicity of installation and operation;
  • Low cost;
  • You can use for the equipment of the sewage system, small tunnels, power lines and heat networks;
  • Protect from groundwater.

The disadvantages include purely technical aspects - the heavy weight of the ZHB rings provides for transportation in a large car, and their installation is possible only when using special equipment.

Classification and volume of zhb rings

These rings are made of heavy concrete B25, the frost resistance of which F-100, the water permeability of W4. The RB rings are labeled according to which you can define the classification of the ring.

Reinforced concrete rings are divided into prefabricated, doubt, with a lid, with a lock and bottom.

Initially, the markings indicate the design type: COP - Wall ring, KSD - Wall ring with a bottom. After the type, the ring size is prescribed, the first group of numbers denotes the diameter of the ring, after hyphena, the height of the product. For example, KS-15 denotes a wall ring with a diameter of 1500 cm.

Before buying a zhb rings, you need to check them for cracks

When installing a cesspool on the site, first of all, the size of future sewage drains is taken into account. Depending on the depth of the seafood, the required amount of reinforced concrete rings and their types are calculated.

The standard height of the rings is 90 cm, but if necessary, you can supplement the design by rings of other sizes. Depending on the needs, diameter is selected - from 70 to 200 cm. The thickness of the concrete wall is 7-14 cm.

The strength of the structure largely depends on the lower well ring - the specialists recommend installing the ring with the bottom. Next are the wall rings and the cesspool is closed with a lid with a hatch. The diameter of the elements of the septica everywhere should be the same, otherwise the design will be unstable and it is possible to leap the wastewater to the ground.

The volume of the concrete ring 1 meter: nuances of the septic troops

A single-chamber septic tank made of reinforced concrete rings should have a bottom and cover. Such a cesspool is considered to be ineffective, it is set most often in the country.

Mounted Stock Empty at a distance of no more than 20 m from the residential building. The further septicch is, the more pipes will have to lay from the sewage in the house to the ZhB septic. At the same time, the minimum distance to residential buildings - 5 m. When installing the septic, the number of people will take into account the sewage system. On average, a person uses about 200 liters of water to sewer per day.

When choosing a rings from reinforced concrete, it is important to know how many liters of stocks can accommodate this design. It is believed that the minimum septicity of the rings is 6 cubes. To calculate the volume of the zhb-ring, you need to multiply the amount of tenants by 200 liters, the resulting amount is multiplied by 3 (the time interval for which the drains are processed in the pit). To obtain the volume of the ring, the final amount is divided into 1000. Based on the tables on the Internet, select the suitable for the diameter of the ZB-ring. In one standard ring of 90 x 150 cm, approximately 1,59 liters of water or effluent is placed.

The pit for concrete rings is best digging by excavator

When installing, the septicity of the rings must be remembered that the surface on which the rings are put should be strictly horizontal.

If there is no possibility to install the bottom ring with the bottom, you can float the dense layer of crushes and pour the cement solution. The top of the septic is covered with a ring with hermetically closing cast-iron sewering hatch.

Celdiction pit from concrete rings without bottom: Montage do it yourself

Before getting to laying the rings, you need to prepare a hammering depth of 3 meters under the cesspool. Its width should be slightly larger than the diameter of the selected zhb rings.

You can pull out the pit under the pit can be spacing yourself, and you can hire special techniques for faster performance.

The bottom of the pit must be aligned with sand, on top of which a concrete ring with a bottom or a conventional wall ring is installed.

The cesspool without the bottom can be installed in those places where there are no groundwater

How to mount septicity from zhb rings:

  1. Install the first ring. Check that it does not clone to the side.
  2. By installing the next wall ring, flood the space between the septic and the pit.
  3. Gradually build a septic tank, not forgetting to check the level of the installed zhb rings.
  4. The joints between the rings should be sealing with sand cement.
  5. Using a perforator or a grinder to make holes for sewage pipes. The waste pipe from the house is installed at a low angle.
  6. If the sewage system consists of several septic, in addition to the drain pipe, it is necessary to pave a pipe connecting septic tanks. This pipe is located 20-30 cm below the waste.
  7. So that the drains do not get into the ground, it is important to choose the proper waterproofing. This uses bitumen or polymer mastic.
  8. The final stage is to install covers for septic. After drying the joints, you can proceed to the use of a cesspool.

Septic from rings from reinforced concrete does not require special rules of operation, but it is important to brush it on time and use special bacteria for better flow processing.

How to calculate the volume of the ring (video)

The work of reinforced concrete septic is largely depends on the quality of the materials from which it is made. All items must necessarily have a correct marking. Observing all the nuances and installation technologies, the waste pit will serve for quite a long time.

Volume of reinforced concrete rings

Rings made of reinforced concrete most often made when arranging land plots. Often, owners of the country area have to make a ring with their own hands. To do this, it is necessary to know the formulas for which the calculation of concrete products is calculated. Products manufactured for well marked according to the requirements of state standards. Marking is the characters specified on the rings by which you can identify information about the size and mass of materials.

For each concrete product issued according to the requirements of the State Standards, tests are provided that allow you to confirm the quality, the stated performance characteristics and stability of products to the effects of negative factors. When summing up, experts take into account waterproof, frost resistance, moisture absorption, compression strength.

Rings from reinforced concrete

Rings from reinforced concrete are special products intended for the arrangement of wells used in water supply systems, as well as water leads. The easiest way to charge work on the sewage system of the private house of one of the firms. However, it is necessary to calculate in advance what amount it goes. If you want to save, you can make a sewer, which will be based on a concrete ring, independently. Production of such products is carried out at enterprises in compliance with state standards. When creating high-quality materials, CDS are used. Production Production involves the use of special shape, concrete and reinforcement, the diameter of which should not exceed ten millimeters.

On reinforced concrete building materials of this type, the marking is indicated that defines their purpose, the size. If we talk about how to calculate the cost of a particular product, it is important to take into account the volume of the rings. Than this figure is higher, the more expensive material.

Varieties of well details

Cleaning bottom CCD 10A.

Well bottoms CCD 10A - the desired detail of the prefaby septica. The durability of the product depends on the quality of their manufacture and correct installation. The bottom of the CCD 10a is released in the form of a monolithic plate of reinforced concrete with several special loops. The bottoms are presented bottoms of different diameters. Rodyshko CCD 10A is produced according to the approved standard. Dimensions of the CCD are calculated so that the bottom withstand the load of the liquid, which accumulates in the container. At the same time, manufacturers take into account the possible mobility of the soil and the impact of groundwater. The CCD is selected on the diameter of other well parts - Rings of the CC, covers, etc.

Examples of parameters of several types of rings KC (height and weight of COP products):

  • Ks-7-1; Ten centimeters, forty-six kilograms;
  • Ks-7-1,5; fifteen centimeters, sixty-eight kilograms;
  • Ks-7-3; thirty centimeters, one hundred forty kilograms;
  • Ks-7-5; Fifty centimeters, two hundred thirty kilograms.

The materials of the COP, CC, whose weight exceeds one hundred kilograms should be special ears. The product that has labeling, for example, KS10-6 is called wall. You can also see the materials with the designation of C6 (reference ring). Products, marked C6, has a height of seven centimeters, the inner diameter is fifty-eight cm, nar. Diameter - eighty-four cm, weight - sixty kg. K06 supporting products are also used when conducting work on sites.

Concrete CC (CO6, KS10) allow you to more accurately determine the height of the container. You can align it with the surface of the Earth or to make the rings be above the soil level. Installation of concrete parts on a special plate will make it possible to raise the well hatch. Due to this, it will be possible to exclude the falling melt, rainwater and the flooding of the hatch. Important when carrying out calculations for CC are the volume of rings. The cubic meter is the main unit of measure.

Calculation of the reference element from reinforced concrete

Parameters for calculating the volume of concrete rings.

To determine the parameters of the manufacture of well elements and other parts from reinforced concrete, it is necessary to first calculate the cost of their production. For calculations, the initial data will be needed: the volume of the concrete mixture on the creation of the rings, the well, the lids; The total consumption of reinforcement and the number of reinforcing mesh per element. The consumption of concrete solution onto the well ring is determined as follows:

  1. First of all, the parameters should be written.
  2. Then calculate the area of \u200b\u200bthe circle (outer diameter). To do this, use the calculation formula (¼ P d2). N denotes 3.14, d - nar. diameter. It is necessary to translate numbers to the meter value.
  3. After that, with the help of the above formula, the circumferential area is calculated (internal diameter).
  4. The area of \u200b\u200bthe concrete product is determined as follows: from the value of the area of \u200b\u200bthe circumference with the Nar. The diameter is subtracted by the area of \u200b\u200bthe circumference from the inside. diameter.
  5. To determine the volume, you need to multiply the height and area.

If you have difficulty counting, you can resort to the use of the calculator.

Conclusion

Septics, tunnels, systems for removing liquids - the main construction objects, when installing which are used concrete rings. These elements were widespread in the area of \u200b\u200bthe device of the wells of various purposes.

Celdiction of concrete rings: how to build a two-chamber sump

The cesspool without the bottom is the simplest sewer construction, relevant at any dacha. Make such a device under the power even the most green newcomer-builder. However, a two-chamber cesspool of a concrete rings, the creation of which is not much more complicated, solves the problem of wastewater removal is somewhat more efficient.

Principle of device and work of such a design

For cladding of the walls of ordinary cesspool without bottom, ready-made concrete rings fit perfectly. They just need to be lowered to the bottom, and then close the seams and carry out waterproofing work. It is easier than concreting the walls of a cesspool pit or lay brick. Such sewer devices are perfect for giving, which is used only in summer, on weekends and on holidays. If the volume of effluents exceeds the cubic meter per day, it is worth thinking about the construction of a two-chamber device.

At the same time, the volume of work will increase at least twice, since it will have to actually dig two pits, concrete the bottom in one of them, to another to arrange drainage, etc.

As a result, the efficiency of wastewater processing will increase several times. At first, the waste of human livelihoods will fall into the first pit, the bottom of which is carefully concreted. In this compartment, solid particles will fall at the bottom, slowly processing in the fermentation process and turning into il. This part of the cesspool from concrete rings must be periodically cleaned.

Tip: To improve the processing of solid waste, cultures of special anaerobic bacteria add to the sump. It should be remembered that such organisms do not tolerate the presence of chlorine-containing components in water.

The sump is connected by an inclined pipe with the second separation of a cesspool, which is a drainage well. The bottom of this pit is not concreted, but fall asleep with a layer of drainage. Wastewater, partially purified in the first compartment, pass natural doctors and go into the ground. Such a cesspool needed in the services of the asserenimizers much less often than the usual, while the probability of soil pollution by wastewater is significantly reduced.

A few words about concrete rings

Typical concrete rings for cesspools are also convenient for the fact that it is possible to easily calculate the volume of the future septicism, multiplying the area of \u200b\u200bthe ring circumference on its height. The first figure specified in the labeling of the concrete product means the diameter of the ring in decimeters, and the second is its height.

For example:

  • KS-10.9 is a ring with a diameter of 1 meter and a height of 90 cm. Its volume is 0.71 cu. m.;
  • KS-15.9 is a ring with a diameter of 1.5 meters and a height of 90 cm. Its volume is 1,59 cubic meters. m.;

    • KS-20.9 is a ring with a diameter of 2 meters and a height of 90 cm. Its volume is 2.83 cubic meters. m.

Holes for sewage pipes in a concrete ring can be made perforator

In addition to concrete rings, you should buy overlap, since the cesspool should be securely closed. For a two-chamber septic, you will need two overlaps. When they are manufactured, they make a round hole to provide access to cleaning. Close the hole with a special hatch, which should also be purchased.

Conducting installation work

Before starting construction work, you should draw up a detailed plan and choose a suitable place. In addition to the desire to preserve the aesthetic type of landscape, it should be noted that the cesspool should be located:

  • not less than five meters from a residential building;
  • not less than 30 meters from the source of drinking water;
  • in a place accessible to the entrance of the special transport of the assessing agents.

Please note: choosing a suitable place for a cesspool, you should consider not only the location of your own home, well or well, it is necessary to take care so that the sewage is at a sufficient distance from neighboring buildings and structures.

To make a two-chamber cessswoman from concrete rings, you need:

  • Drop in the appropriate place two pita (sometimes one spacious pit).
  • Relieve the bottom of the pit, in which the sump will be built. After drying in concrete, cracks are almost inevitably formed, which must be embossed to ensure sufficient tightness. This stage will take about a week or a little more.

Tip: To avoid concreting of the bottom of the pit, you should buy a concrete ring, the bottom in which is already arranged.

  • Install concrete rings in the pit.

    • Celling the seams and waterproofing of the structure, for example, with a cement solution and liquid glass, bitumen, and the like.

Lower the concrete rings in the kitty should be careful not to damage the design of the connection site of concrete rings. It is necessary to carefully close and process the waterproofing layer.
  • Install concrete rings on the bottom of the second pit.
  • To put on the bottom of the drainage layer: crushed stone, broken brick, etc.
  • Pour the sewer pipes that are connected to the house, as well as connecting the separations of the cesspool among themselves.

Tip: The bias under which the sewage pipes are paved, should be about 2-3%, and the trench depth must be at least 80 cm to prevent the design of the design in winter.

  • To check the tightness of the design, correct the identified shortcomings.
  • Install overlaps with hatch and vent hole over each branch of the cesspool.
  • Cutting the design of the ground.

The cesspool of this type is much more convenient than the usual, the increased costs of its construction will soon pay off.

In order to equip an individual sewer system in a private country house there are several ways. But despite the huge range of more modern and newest building materials, rings from reinforced concrete are most in the greatest demand. Such popularity is achieved due to the strength, reliability, and frost resistance of such products, as well as considerably the size of the concrete rings for sewage.

The main characteristics of concrete rings

The use of precast concrete structures in the production of construction makes it possible to significantly reduce the work of work, increasing performance. It is the rings that are considered a product that is most common in construction processes.

Application area

The scope of use of such products may be the most different:

  • Construction of drinking wells;
  • Arrangement of viewing wells necessary to monitor the state of communication systems;
  • Construction of septicists;
  • Arrangement of storm sewage and so on.

Advantages and disadvantages

The advantages of the designs of this kind include:

  • High level of strength;
  • Durability;
  • Frost resistance;
  • Ease of installation;
  • Ease of operation;
  • Low price.

But there is one significant disadvantage that lies in a large weight. So, for example, the answer to the question of how much the concrete ring weighs with a diameter of 1 meter, the value of 600 kg becomes. And this suggests that transportation of such a product is impossible without special equipment to the place of development.

Dimensions of structures

Overall dimensions Weight of concrete rings are two parameters directly related. As a mass, so the overall parameters of such products may be different, depending on the type of product being created and its use.

To date, there are rings of the following sizes:

  • KC-10. The height of such a product is 0.9 m, the outer diameter is 1.16 m, and the weight of the concrete ring 1 meter of the inner diameter is 0.6 tons;
  • KC-15. This ring is called average and has the following parameters: height - 0.9 m, the inner diameter is 1.5 m, the outer diameter is 1.6 m, the mass of the product is 1 tone;
  • KC-20. The ring is out - 0.9 m, with a weight of 1.5 tons, and the diameters of the external and internal 2 m and 2.2 m, respectively.

Note!
Marking The product consists of CC or COP letters and indicating the size of the internal diameter of the product in decimeters.

Modern manufacturers offer rings with a diameter of 0.72 to 2 meters and a standard height of 90 cm.

In addition to such standardized products, there are also non-standard, which are called good.

Through such products from typical can be different in the following parameters:

  • Form of construction itself;
  • The wall thickness, which varies from 65 mm to 115 mm;
  • The presence on the surface of the locks that allow you to simplify the process of assembling the structure;
  • Height;
  • Diameter.

So, for example, you can purchase concrete rings of large diameter (more than 2 m) or even square products.

Council. The advantages of using reinforced concrete structures of the square form include the possibility of installing them on the concrete slab.
This eliminates the need for the structure, and besides, the square pit is easier than the round.

Types of rings

By the type of design of this kind, they are divided into two main types:

  1. Straight. The connection of such rings is made using metal brackets and cement mortar;
  2. With a lock - Such products are endowed with an annular protrusion at the top and notch in the bottom. The installation of such elements on each other allows you to create durable compounds, which eliminates the probability of displacement.

Manufacturing technology

The serious load on this kind of product in the process of their operation determines the need to give them high strength indicators. That is why only high-quality mortar with small grain is used in the production process. This is usually concrete related to brands from M200 to M500.

The manufacturing process is divided into the following steps:

  1. Prepared a form for fill;
  2. The form fit the reinforcement frame;
  3. Pouring is performed by the finished concrete solution;
  4. Disposable voids by vibration.

Now the product remains to dry in the corresponding microclumatic conditions.

Making rings at home

If you decide to make reinforced concrete rings with your own hands, you should certainly know:

  • To obtain a quality product, it is necessary to use the M400 grade cement and above;
  • As a small filler should be washed quartz sand;
  • Large filler - a little-one gravel.

Instructions for the manufacture of products of this kind at home is as follows:

  1. Formwork arrangement. You will need to build 2 cylinders, of which 1 for inner diameter and 1 for external.

Council. As materials for making formwork, boards, plywood, roofing sheet, etc. can be played.

  1. Choose a smooth area and install internal and external cylinders on it, so that the walls of the products are equidistant to the entire circumference;
  2. Along the perimeter of the formwork at equal distances, place 10-12 metal reinforcement rods with a diameter of 8-10 mm;
  3. The resulting frame must be consolidated by wedges, which will move up as the shape of the solution fill;
  4. In order to easily separate the finished product, lubricate the walls of the exhaust machine oil;
  5. Fill the layer of concrete about 10 cm and endure with the help of a metal pin using the piercing method. Thus, fill out the entire form;
  6. Sprayed formwork coo with a dense cloth to protect against the sun;
  7. After 3-5 days, the formwork can be removed and leave the product to seek another 7-14 days, bounce it from the Sun and moisturizing several times a day.

Sewage arrangement from progress rings

Sewage installation technology provides the process of concreting the bottom of the well in order to prevent sewage penetration into the soil.

In addition, it is necessary to insulate the bottom of the well, you also need to water the joints between the rings.

For this purpose, the following building materials can be used:

  • Plaster mixes;
  • Liquid glass;
  • Rubber seals.

It should not be forgotten that in the process of the freezing of the soil, its displacement occurs, which leads to a certain movement of concrete structures. In order to solve such a problem, specialized plastic inserts made of polyethylene, 0.8 cm thick, are used. Today, such inserts are produced in a large assortment, with different diameters and height.

Finally

Concrete rings - prefabricated structures in demand in the modern market for various purposes. No matter which object you are going to build, in the modern construction market you will certainly be able to find structures suitable in size and form.

But if there are still no such products, you can easily make them yourself, because this process is easy and will save on the transport works. And the video in this article will reveal you even more interesting information about what reinforced concrete rings are.

Rings for wells Reinforced concrete: species and purpose

For high-quality installation and arrangement of a well of any type of construction use reinforced concrete rings. This design is a rounded reinforced concrete product, a height of 10 to 90 cm, and an equal diameter from 0.7 to 2 m. Size Rings for the Well It is selected individually, depending on the purpose and type of communication itself.

ZBB rings are used for such types of wells:

  • Water supply and sewer;
  • Water intake and gas pipeline;
  • Wells for the installation of electrical communications under the ground;
  • Collector wells, etc.

All concrete rings used in construction should be made of cement grades 200/500 at the state enterprise in accordance with established standards (GOST 8020-90). Such reinforced concrete products are mandatory marked by alphanumeric brand.

Benefits of concrete rings for wells

ZBB products used to high-quality wells for various purposes are distinguished by the following advantages:

  • Strength and durability;
  • Ensuring the tightness of the vertical or horizontal tunnel;
  • Sufficient simplicity in montage;
  • Acceptable price of well elements.

​

Reinforcement of reinforced concrete rings

The technique of making rings for the well does not always involve their reinforcement with a steel rod, but it is precisely such a production method that allows you to achieve maximum strength and durability of products.

At the factory reinforcement of concrete rings for a well, the dimensions of which are standard, occurs using vibropress technology. This allows you to achieve the maximum shrinkage of the concrete mix in the form and completely eliminate the formation of the destructive air pores in the walls of the product.

In addition to the size of the GB rings for wells, the distinctive characteristic of the ZB-product is its marking, which allows you to understand the purpose of the rings itself and its size. So, the most famous in the construction industry are such alphabetic designations on the rings:

  • Ko - Ring reference, intended for the fundamental part of the well;
  • Ks. - wall ZBB ring used in small or extremely narrow areas of wells;
  • Qg - GBB ring intended for use in gas and water pipes;
  • KFK - reinforced concrete rings used in the installation of wells for the collector network or the drainage line;
  • CLK - Rings designed for mounting in waterproof wells or rain sewage diversion in the city.

In addition, in addition to the letters in the marking of the RB rings, the numbers are used, which indicate the height of the ring for the well and its diameter. So, for example, the figures in the marking of KO-10-7 are deciphered as: a ring of a diameter of 10 dm and a height of 70 cm.

In addition, the ring for concrete communications and wells can also be equipped with additional elements (bottom plate or overlap, fully corresponding to the diameter of a specific ring). In this case, the slab overlap will be labeled by two letters of PP or PC, and the plate for the bottom - Mon or PD. Such elements are used to complete the well sealing of the well from above and below, in order to avoid getting into dry communication of groundwater, and into the well with drinking water - soil particles or to distribute the load on the entire design.

IMPORTANT: The first digit in the designation of the RBB rings is always the diameter of the ring, and the last digit is the height of the ring for the well.

Sizes rings for wells. Main, Dobly, Repair and Other

Select the size of the ring of the well is necessary, taking into account the likely use of the amount of water on the family. Only carefully all silent, you can start the formation of a certain diameter, and the purchase of rings.

In addition to the main types of reinforced concrete products-rings in the construction industry, there are also additional types of products. Here the sizes of the RB rings for the well are selected individually, which allows you to make the necessary component of the well to complete the completion of hermetic communication.

Such types of rings are:

  • Dobly (intended for dunklement of the length of the well);
  • Auxiliary (used as a supplement to the bearing solid structure of the well).

​

Installation of GBB rings with GOST size

High-quality rings for the well need to be carried out using special heavy equipment, which allows you to mount the entire well without the risk of destruction of the entire design with time.

According to construction technologies, concrete rings for wells must be installed in advancely prepared pit and tightly drive each other. Possible gaps between the joints of the rings must be thoroughly close with cement mortar. In addition, additional moisture insulation of all seams is supposed to prevent groundwater from entering communication.

Modern GBB rings for wells with sizes according to GOST can be two types:

  • A simple ring with a flat rim (mounted by using fastening brackets on joints);
  • Ring ZBB, having a lock connection in its design.
  • The latter is considered more reliable because it avoids the possible offset of the entire well structure as a resultsoil movement. Such rings are mounted on the principle of the compound of the groove / ridge, which ensures the complete tightness of the entire communication.

Important: When installing the well, first of all, it is necessary to lower the section with the bottom. This will make the bottom of the well as sealed as possible and clean. And when installing deadlocks of the well of various communications, it is best to use the slabs of overlaps. It also applies to reduce the load on the entire design.

Reinforced concrete rings for a well doof

In addition, you can choose the diameter and the size of the well ring yourself, based on your needs, and make the necessary items at home. To do this, you will need cement-sandy solution, fittings (iron rods of the required section), the form of the desired diameter and height.

Made rings for wells in home conditions by vibration sufficient is quite difficult. Therefore, it is necessary to carefully catch the solution by thoroughly filling the shape under the ring.

You can remove the form from the finished rings after two to three days. After that, the ring should dry at least a week before installing it in the well.

Important: Do not forget to periodically wet the finished product so that it does not stop in the sun and did not crack. In addition, while drying up the product, the size of concrete rings for wells can change a little.

Before buying concrete rings, it will not be completely superfluous to calculate the required septicity of concrete rings. There are many ways to carry out such a calculation, but it is necessary to understand that each of them allows you to get a result with a different degree of approach. This is primarily due to the fact that each of them as the initial data takes to calculate the averaged value of water consumption per person living in the Human House, for quite understandable reasons, this value may be seriously different as in a smaller and most side. Nevertheless, the norm is considered to be 300-350 liters of stocks per living per day, but we do not recommend using these values \u200b\u200bin the calculation, at least without conducting additional analysis.

Let's look at the main aspects that affect the choice of the required septicity of the concrete rings, as well as choose the Ribbons for the construction of such a septic.

The formula for calculating the septicity of concrete rings

V \u003d N * Q * 3/1000
Element values:
V - the volume of septicism in m3;
n - the number of consumers permanently residing in the house;
Q - water consumption per living, per day;
3 - duration in days of wastewater purification cycle (according to SNiP).

This is a very simplified version, but its accuracy is enough to choose the amount of septicity for a private house. For example, based on the most frequent cases, for the 3 permanent people in the house, the septica of the 3-concrete rings of the 1.5 M of the KS15-9 \u200b\u200bseries is quite enough, when consumed 400 liters of water per day, and even some reserve remains on the tank. Constructions. Unfortunately, it is clear from such a calculation that We are talking only about the volume of the receiving camera of concrete septic (which is sealed, isolated from the soil, in particular - the bottom of the septica of concrete rings Mon15 is used). This calculation cannot be used for cesspool. After all, firstly, the ability of the soil under the bottom of such a pit to filter the suspension will quickly decrease, and secondly, the requirement of SanPiN of the minimum of 3 days, for wastewatering.

Since it is calculated precisely the septic, in the design of which several overflow containers and a drainage well, or the filtering field are included. The resulting result from the calculation should be divided by at least two tanks. By this, you will not only extend the service life of the septica and the drainage well, but also provide better cleaning of wastewater, as well as reduce the need to pump the sludge to a minimum.

For many types of construction, modern technologies involve the use of reinforced concrete rings. Of these, all sorts of purpose are very often built, and therefore such construction elements are very important when installing and installing any structures.

Most often, there may be sewer wells, septic tanks or accumulative tanks. To understand which rings are suitable, and for which they are work, it is necessary to carefully examine their parameters and specifications.

Reinforced concrete rings are the building material is ready-to-see, which is manufactured by software. In the manufacture of all sorts of mixtures of different brands of concrete, rubble of various fractions, sand and metal fittings are used. That is why such structures are called reinforced concrete.

The presence of metal inside the bulk concrete provides high strength and reliability of the rings. Metal reinforcement has resistance to the stretching of the entire structure, and concrete protects it from the effects of metal corrosion and is a very stable material for compression.

Thus, all finished products have superior features in comparison with concrete rings, without reinforcing reinforcement.

Ready rings from reinforced concrete can be used in various types of construction.

These may be such types of installation work:

  • installation of viewing wells for water supply or sewer external pipeline networks. Especially on swivel or connecting areas;
  • use under cumulative containers, both for drinking wells and sewer;
  • installation of accumulative or drainage wells for the drainage system of storm or any other sewage system, where the main goal of such a well is to reduce the level of groundwater accumulation;
  • installation and installation of gas pipelines.

The collectors of horizontal arrangement underground are not advisable from reinforced concrete rings, because the height of such rings does not allow to build a high density tunnel. Such tunnels will constantly leak and are not hermetic.

For the construction of collectors, either special pipes are over 1000 diameters, or whole mines are built.

Use for sewage and form

Under the construction of septica from reinforced concrete rings or drain pit, building materials should be used high quality, and therefore reinforced concrete rings must be the highest brand.

In addition, it also follows to the rings to choose the same high quality and bottoms, overlap and sewer hatches with lids.

Construction of concrete rings is cost-effective because the price and quality fully justify each other, and accessibility for any buyer of such a building material is high.

For sewage arrangement, three types rings are used:

  • with a lock ring connection. On each ring in the upper part, special protrusions are made, and in the bottom - notch. When their installation occurs, the rings as it were on one to another, while concluding in the castle. When operating, such a solid structure cannot move or shifted, and therefore the rings will always be in that position in which they were initially installed;

Photo: with lock ring connected
  • straight rings without a lock. Such rings during installation are connected and sealed at the joints with each other with metal brackets or cement mortar;

Photo: straight rings without lock
  • filtration rings. The rings have such a plan, uniformly located on each other, holes. Through these holes, water seeps into the soil, and therefore such rings are ideal for mounting filtration sewer wells.

Photo: Filter Rings

In addition to large and high rings, which are used when installing a sewer well as the main material, there are also an additional type of reinforced concrete rings, the dimensions and parameters of which differ significantly from the main.

First of all, it is adjusting railway rings, which are very low in height, thick in the width of the walls and a bit narrowed in diameter.

With the help of such rings it is very convenient to adjust not only even, strictly horizontal, the surface of the entire structure of the well, but you can also adjust the volume of the structure, narrowing the inner space to the necessary one.

Also, except for the adjustment there are in the sale of good rings, with which it is very convenient to adjust the height of the sewer well, when the ordinary ring is too large, and it remains very little space to the surface of the earth, plus there will be overlap.

Therefore, such narrow, or rather - low, good rings in such situations just save the situation, completing the design for all standards and rules of SNiP.

In addition to the types of reinforced concrete rings to complete the complete design in this case, both reinforced concrete platforms or bottoms for the installation of rings, overlapping with or without necks, which protect the finished sewer facilities from atmospheric precipitation, and sewer hatches.

The advantages of operating rings made from reinforced concrete is the high dates for their use.

On average, when frost-resistant and resistance to mechanical or chemical impacts, such rings are capable of serving at least 25 years.

Reinforced concrete structures are perfectly transferred to an alkaline and acid medium, perfectly show itself when exposed to active yals and fermentation of sewage drain, and therefore for installation under a septic tank, a drain pit or a filter well, reinforced concrete rings are the ideal option.

For wells with drinking water

An excellent option for mounting reinforced concrete rings for a drinking well is the rings with a lock. It is they who are tightly adjacent to each other, will not give to leak on the joints.

On sale in the markets can often be found rings with a cast bottom, which is not entirely suitable for the construction of a drinking well, because the bottom will limit access to the flow of spring water into the accumulative well.


Photo: Reinforced concrete rings for wells with drinking water

Rings with a lock are perfectly suitable so that on top to the last ring it was possible to install a wooden log house, a house for manual water supply.

Little advice when buying reinforced concrete rings ask how the manufacturer when casting the rings used lubrication for molds for casting with wax liquid.

It is at such a manufacturer and it is worth buying rings under a drinking well because such rings are most suitable for the installation of a well structure with drinking water.

Due to the thin wax film, which is not simply applied to the surface, and partially absorbed into the concrete, oil stains will not be formed on the surface of drinking water or any other dispersion garbage or surplus, which should not be in drinking water.

Dimensions

The most common parameters of the reinforced concrete rings for installing them under a septic tank, a drain pit, a cumulative or filter container are used by the rings of two standard sizes:

Photo: Dimensions of reinforced concrete rings for sewage

It is these samples that will most optimal in the overall design of a type of sewer well for a private house, cottage or cottage.

The height, more precisely, the depth, such wells is conveniently adjusted by simple buildup of concrete rings by installing them one on another.


Photo: Sizes

However, for the installation of sewer rings from reinforced concrete, sizes are not the only option that offers a manufacturer in the building materials market for sewage facilities.

Most of the firms of the players consider it profitable to produce reinforced concrete rings of non-standard sizes. Especially if such exclusive orders come from various enterprises, hotel complexes, recreation bases and other large-scale objects that need to be maintained with autonomous sewers.

The volume of rings

V \u003d π x R² x H, where

V. - internal volume of railway rings, π - constant value - 3.14, R² - inner radius Ring rings, H. - Height railway rings. The wall thickness of the ring (in fig. Indicated - B) is not taken into account, as the volume of the internal space of the reinforced concrete ring is calculated.


Photo: Data for determining the volume

Almost all rings have a standard height and inner radius, so it is not difficult to calculate the inner volume of the product.

So for the most encountered standard structures there are already generally accepted calculated volumes of the rings of a certain brand:

  • COP 10.9 (100 cm) - volume 0.71 m³;
  • COP 15.9 (150 cm) - volume 1.59 m³;
  • CS 20.9 (200 cm) - volume 2.83 m³.

All these indicators are used for calculations during the design period of a well from reinforced concrete rings, and therefore they should always be paid special attention.

Weight

If we consider the parameters of all types of rings, including adjusting, voluntary and filtration, then you can see a holistic picture that shows us the weight of each of the standard design of reinforced concrete rings.


Photo: Weight of reinforced concrete rings

For laying plumbing highways, the most popular rings weighing 630-640 kg, and for sewage networks use smaller ring structures.

Rings from reinforced concrete cannot be made easier by weight, otherwise inside their walls there will be hollow spaces, which will significantly reduce the strength of the entire structure.

It is due to heavy weight that the entire design of any reinforced concrete well becomes monolithic and practically immovable, which increases its operational characteristics.

Manufacturing according to GOST.

All the production of reinforced concrete rings for any structures and communications is always based on the regulatory documentation GOST 8020-90 dated 07/01/1990 of the introduction.

Standard wall reinforced concrete rings, which are most often used under the construction of wells, have parameters and characteristics:


Photo: Parameters and Characteristics according to GOST

In general, rings of different labels are used under the construction of wells:

  • COP - Wall Ring;
  • KC - Ring.

If the manufacturer performs all the requirements, recommendations and norms, according to GOST, then its products will be valued above all other manufacturers because it will show itself with the best of operational parties.

But, if the norms and standards of state legislative documents and standards are violated during production, then reinforced concrete rings of such manufacturers will be the worst in the readings of their use and operation.

So, for example, in the improper use of cement (dosage disorders or kneading in a concrete solution of poor-quality cement of another brand), concrete rings, a few months after installation, will begin to catastrophically crumble, their integrity will be violated, and the whole design will ultimately come into disrepair .

Rings with a bottom

Reinforced concrete structures consisting of a ring with a deaf bottom are often used to install sewage wells or septic plates, to arrange chamber-sumps.

It is in such a cell that the sewage system should be lagging and to be treated with bacteria that convert the drains on IL and water. In such wells, Il must gradually accumulate, and then, removed from the well.

Therefore, such a hermetic design as a ring with a bottom is the ideal option for the arrangement of such an autonomous sewer facility, with a ready-made hermetic and waterproof bottom.

Important! If you do not use such building items, then you will have to make a concrete site separately, for which the rings and their joints are then cooled, which gives a completely high-quality and hermetic connection.

In the presence of groundwater, such compounds will be very quickly going to flow, septic tightly with excess groundwater, and, in the end, it can completely fail, so it is best to use reinforced concrete rings to use reinforced concrete rings to the sewage.


Photo: Reinforced concrete rings with bottom

The most common technical indicators and characteristics of such rings with the bottom are the following:

  • ring having an inner diameter of 100 cm has a height of 90 cm, and the weight is 830 kg;
  • a ring having an inner diameter of 150 cm has a height of 90 cm, and the weight is 1400 kg;
  • the ring having an inner diameter of 200 cm has a height of 90 cm, and the weight is 2300 kg.

Thanks to these indicators and the above formula, the total amount of septica can be calculated by calculating the internal volume of the rings from reinforced concrete with the bottom, plus the volumes of the rings and, if necessary, the volumes of adjusting or good rings.

Production

The production process of manufacturing reinforced concrete rings consists of several very important stages:

  • the first stage is the preparation of concrete mix. For the manufacture of reinforced concrete rings, most often, cement grades M400 and 500 are used because it is such a cement that has high adhesion and strength;

However, this is not enough for a reliable construction of the rings. For plasticity, various plasticizers are used that protect the design during drying not only from the seeding of cement, but also possess moisture-proof properties, which is an indispensable characteristic when installing accumulative water supply or sewer wells.

Crushed stone is used not larger fractions than 20 mm. In addition, sand and water are added to the solution. All ingredients are mixed in the concrete mixer of the production type of the SB series, "SPb".

It is these concrete installations that are capable of allowing a solution from 0.35 to 0.45 cube for one cub.

  • the second stage - casting in the form. The resulting mixture is poured the form in which the fittings is already placed. This can do it both manually and with the help of a special dosing supply technique;

The bottom of the form is equipped with a metal pallet, which has special attachments and, if desired, the pallet may be disconnected. The outer formwork is located in the installation and is put on the vibrostol core.

At the end of the fill with the concrete mixture of the form with the reinforcement, the plumbing empties are stacked, for the creation of special holes.

  • the third stage is the coupling or seal of concrete mass. This happens using the inclusion and operation of the vibropressor. Very effective adaptation, since his work is little expensive in terms of spending time. The dummy leaves about 60 to 200 seconds;
  • fourth stage - rubbing the top of the rings. To do this, use a rotary beam;
  • fifth stage - installation of outdoor formwork. The outer formwork is installed necessarily with a pallet on a flat horizontal surface. Give her to stand for some time, and then free from the form of the finished product. Usually the deadline for solidification and drying of the finished product in the summer period accounts for 7 days.

The entire procedure for manufacturing reinforced concrete rings is carried out according to the standards and standards of GOST documentation.

Any deviations from these requirements lead to poor-quality products, and subsequently both the impaired integrity and depressurization of entire structures and structures from such rings.

How to make it yourself

The manufacture of reinforced concrete rings with their own hands should not deviate from GOST 8020-90. Otherwise, your products will turn and crack.

To begin with, you can make the formwork itself or the shape for the fill of the reinforced concrete rings alone. The formwork is made of two collapsible iron rings and, also collapsible, bottom.

Some prefer to make a formwork from wooden rings and bottoms. In any case, they must be well sanded into each other.

Some masters are managed as a formwork to use ordinary metal barrels of different diameters, pipes or air ventilations of large diameters. The main thing is that these forms are cylindrical.

For making formwork with your own hands, you need to prepare such materials and tools:

  • metal cylinders (old barrels);
  • door canopies (can be used and window);
  • fasteners for mounting canopies to metal cylinders;
  • a piece of metal;
  • bulgarian and disk metal cutting nozzle.

On the side of the outer walls of the larger diameter cylinder, two longitudinal vertical lines are marked, which are placed the design into two equal halves.

Along these lines you need to attach in a pair of ordinary door canopies. In order for the sashs of the canopies on both sides of the marking lines themselves, the bends of the canopy should coincide in the line itself.

The same markup is applied to the inner side of this cylinder, along which the baccoon must be made of cuts.

Thus, the cylinder is cut into two parts and the folding form is obtained, which can then be closed, using as fasteners or clamps, canopies and spindles.

Important! Now it is necessary to prepare and process the cylinder of a smaller diameter, which will be placed inside the large cylinder. Also, two parallel marking are applied from within the smaller cylinder.

The distance between the longitudinal lines is taken on 1/3 of each other from the entire circumference. The same door canopies are fixed on the inside and on the same scheme as in the case of the preparation of the larger diameter cylinder.

Next, the grinding cylinder must be cut on the line alone. After that, the hinge pieces are disassembled, and then, they are collected again so that the finished design of the inner cylinder was higher than 5 or 10 cm external.

Check if the outer cylinder opens easily, and the inner - inside. If it is easy, it means you did everything right.


Photo: Production of reinforced concrete rings do it yourself

Now it is important to make a concrete solution properly and prepare the appropriate fittings.

The reinforcement can be made as independently, by the method of interlacing aluminum or metal wire in the form of a mesh, or you can buy ready-made flexible, but the solid fittings and install it in the cylinder support ring for the fill of concrete.

For the manufacture of cement or concrete, binders, tools and devices are used:

  • sand;
  • gravel;
  • rubble shallow fraction;
  • cement brand M400 or M500;
  • shuffling shovel;
  • trough, old baths or other large containers;
  • garden or construction car.

When the concrete is kneading, the ratio of all substances and materials should be so - per 2400 kg of concrete mixture should be used:

  • 300 kg. cement;
  • 150 kg of sand;
  • 1200 kg. rubble;
  • 150 liters of water.

The water-cement ratio should not exceed 0.7 (in the above ratio, a ratio of 0.5 is used because otherwise the strength and viscosity of concrete will significantly decrease.

First, cement and sand is mixed, then water is added, and then gravel or crushed stone. Everything is mixed with a shuffle shovel. All further work takes place at standard stages that do not depart from the norms of the GOST:

Photo: order of work on the manufacture of rings

With my own hands, one person all this should be done there is no possibility, and therefore surely find another or two people who would be able to work physically.

All work on the pouring of concrete in the formwork is quite heavy, so there is a large physical force and constant mechanical efforts.

Installation

If you need to equip such an autonomous structure on your incoming site, like installing a reinforced concrete ring for a drinking or observation well, then you also need to understand the entire process of installation and installation of such heavy structures.

First, as when the pouring, workforce is needed here, and therefore the installation of reinforced concrete rings is performed using several working and lifting and transport equipment.


Photo: Installation of reinforced concrete rings

First of all, it is necessary to dig up the pit for the installation of a larger sealing well by 20-30 cm than the ring diameter. If your primer has a close arrangement of groundwater, then it is better to make a sump from reinforced concrete rings.

And for this, the pillow is first made at the bottom of the sand and rubble, a reinforced concrete ring is installed on the pillow, the wall ring on it is installed on top of it and then the height or depth of the well-sump for autonomous sewage takes place.

You can take not only high rings, but also low, called Dobly. They are especially for this and are intended.

If your rings without a lock, then use metal brackets to connect their joints, which can be mounted into the walls using a perforator. And then it is necessary to make all the cement mortar.

Important! If you use reinforced concrete rings to install in a drinking well, then it makes sense to install rings exclusively with lock protrusions so that they fit tightly to each other during installation.

The bottom of the drinking well is pumped up with a drainage pump so that water does not interfere with work.

While the water has not accumulated, it is necessary to pour 20-30 cm of a crumbbed layer to the bottom of the bottom and install the adjusting reinforced concrete ring on such a pillow, which will serve simultaneously and the platform for the wall rings and, at the same time, such a ring has no bottom, and therefore water through it The hole freely will accumulate in the drinking well. On the adjusting ring from above, wall rings with impregnating wax fluid are installed, forming a well.

Important! All reinforced concrete rings are desirable to sprinkle with a dry mixture of sand and cement for the fortress and structural strength inside the Earth.

Waterproofing

In some cases, it is necessary to urgently hydroize concrete rings. Such cases are then when the groundwater from time to time is washed with the construction of the well from the reinforced concrete rings, and therefore it is necessary to be treated with waterproofing materials in advance, during the primary mounting.

If this is not done then reinforced concrete structures are exposed to various types of corrosion:

  • embossing and leaching of concrete from the design;
  • the destruction of concrete under the action of magnesial or sulphate salt substances;
  • surface destruction under the influence of carbon dioxide;
  • cracks and pumping pieces of concrete due to sudden temperature and humidity drops;
  • the surface is destroyed due to the action of fungal and molding microorganisms;
  • disorders of the integrity of the coating as a result of improper installation, preparation of concrete and care;
  • the oxidation of metal reinforcement, as a result of the lack of waterproofing and, as a result, the complete destruction of the reinforced concrete structure.

All these, and many others, problems can be avoided if it makes a solid and local (local) waterproofing waterproofing waterproofing.

Solid waterproofing is carried out using such mastic, mixtures and suspensions as:

  • penetrating deep waterproofing;
  • injection waterproofing;
  • polymer cement and any other coating waterproofing;
  • polymer waterproofing;
  • waterproofing with special rolled materials.

Photo: Waterproofing

To local waterproofing, it is possible to attribute the joints and seams by plumbing silicone or sealant, which perfectly copble with their task not to pass water.

Important! When applying such materials, they need to be mastered that there is no gaps anywhere.

Not only polymer-cement or polymer waterproofing, but also those manufactured on the basis of bitumen are very well and widely used. In any case, these works are no less responsible matter than the installation itself.

After all, all your installation work will go to the pump, if you are badly protected by reinforced concrete design from the penetration of moisture and water flows.

Prices

Prices for well rings from different manufacturers and even markets have no significant, but still difference.

Therefore, we will imagine several options for price scatteries in order to make it easier to not just compare, but even conduct the calculations of the future well structure from certain reinforced concrete rings.

For rings with the bottom of its price categories:


Photo: Price Table 2

The rings with the lock are also at a price different from simple rings with a flat surface:


Photo: Price Table 3

With regard to sales of reinforced concrete rings near St. Petersburg and the city itself, the cost is not much, but also different:

Photo: Price Table 4

In any case, what kind of reinforced concrete rings you would have chosen, it is necessary to clearly know the rules for their installation, maintenance of their surfaces and protection against moisture.

Important! It is also very important to correctly calculate the volume of the future well made of reinforced concrete rings. All these installation and calculation procedures must be done in complete coordination with the documentation of the GOST standards.

Then you can independently not only make such rings, but also to establish them reliably and for a long time.
