Reinforced concrete rings for wells: types, markings, production nuances + the best offers on the market

Reinforced concrete rings are used in the construction of functional and inspection points of underground engineering systems. They are used in the construction of water supply and sewer wells of various categories and purposes. In order to correctly select reinforced concrete products, you need to know the performance characteristics.

We will talk about what physical, mechanical and practical qualities reinforced concrete rings for wells should have. The article we propose provides recommendations for selection and discusses the specifics of labeling. A rating of responsible manufacturers offering certified products is presented.

General description of reinforced concrete rings

The principle of production of reinforced concrete rings regulates GOST 8020-2016. Explains the purpose of the structures, size and markings GOST 8020-90.

The well ring is a monolithic structure, shaped like a hollow cylinder. It is made from heavy poured concrete mixtures, different fractions of crushed stone, sand and specific chemical additives.

Reinforced with metal rod and wire to obtain the following characteristics:

• increasing tensile strength;
• strengthening basic strength;
• increasing resistance to compression during operation.

Used in industrial construction to create collectors, water supply, sewer and gas pipelines. Used for laying underground cable, electrical and telephone networks.

In the private sector, reinforced concrete rings are used:

• in the building water intake wells;
• in the arrangement septic tanks with different numbers of cameras;
• in construction absorption wells, collector and observation points all types of sewer systems.

If there is a quality waterproofing ensures complete tightness of vertical shafts and horizontal lines. Does not require regular maintenance and does not lose specific qualities and strength characteristics over time.

It takes little time to install a communication system made of reinforced concrete rings. This aspect makes the products particularly attractive in the eyes of wholesale customers and individuals involved in arranging comfortable living conditions in their own homes and garden plots

Types of reinforced concrete modules

The simplest standard models are produced without additional fasteners. Their end resembles a smooth, even rim both at the top and at the bottom.

When laying, they are placed one on top of the other and fastened with metal brackets. The joint area is covered with cement mortar or dry repair mixture.

A hydraulic seal can be used as a sealant for well rings. The material consists of a special grade of cement and quartz sand.It hardens quickly and expands over time. Protects reinforced concrete mains from sewage penetration

After such treatment, the system acquires optimal integrity and tightness. Correct insulation in the contact area of ​​concrete elements extends the operational life of the shaft and almost completely eliminates water leakage through the cracks between concrete elements.

Despite their reliability and strength, standard rings without a lock are suitable for installation in regions with low seismic activity. Strong ground movements can lead to displacement of modules and cracking of cement in the joint area

Euro-rings are available with a practical milling-type locking connection. There are protrusions at the top of such products, and deep recesses at the bottom.

During installation, the elements are inserted into each other, thus providing a monolithic and strong connection that does not require additional processing in the joining area.

When purchasing well rings with an end lock, you should carefully monitor their quality. Poorly cast joining parts will complicate the work and require the use of diamond cutting to eliminate errors and imperfections

This facilitates and speeds up the process of creating a communication system and reduces the overall financial costs of the project. A well shaft made of Euro-rings with a lock is not afraid of seismic activity with shifts and maintains the integrity of the structure even on very unstable soils prone to subsidence.

A monolithic glass is a one-piece structure made of a row ring and a bottom. Used in places with increased requirements for tightness, for example, for sewer tanks.Provides a high level of protection to the surrounding soil and does not allow the contents of the well to seep into the ground or enter groundwater.

Labeling and production process

The entire process of manufacturing rings for wells is clearly regulated by separate legislative acts and technical conditions. GOST 10180 describes in detail the quality and strength characteristics of a concrete mixture suitable for the production of modules.

Well rings made of concrete cannot be installed in areas with seismic activity of more than 8 points and in permafrost regions. Such difficult operating conditions require slightly different design and technical options and solutions.

Standard 10060 determines the requirements for frost resistance of the material. The required level of water resistance is reflected in the document 12730. Deviations from the norms are allowed in minimal percentages and only for certain parameters.

Technological features of factory production

To produce a well ring, a professional concrete mixer, an automatic vibroform and a crane-beam, designed to work with loads weighing from 1 to 2 tons, are required.

A special concrete mixture is used as raw material. It includes:

• fresh additive-free cement with a good rate of strength gain;
• coarse sand with crushing of 2.0-2.3 microns (preferably without or with minimal presence of clay lumps and dust particles);
• crushed stone fraction 5-10 mm, but not more than 5-20 mm;
• process water without impurities;
• superplasticizer.

All components in a certain proportion are placed in special equipment.It thoroughly kneads the composition, giving it a homogeneous, fluid consistency without lumps or clots.

Industrial concrete mixers are equipped with a three-phase motor, operate quickly, have high power and produce a large batch of concrete mixture in one cycle

At the next stage, reinforcement elements made of steel wire with a diameter of 8-12 mm are placed in the molding container (formwork). This frame gives the ring additional strength and provides good resistance to compression/tension during operation.

There are two vertical rods on opposite sides of the structure. They act as ears and facilitate the subsequent removal of the ring from the mold.

Then the prepared cement composition is poured inside the formwork and automatic vibration is activated. During the processing process, all voids are evenly filled, and the concrete acquires the necessary integrity and density.

After 24 hours, the product is removed from the vibroform and moved to an open area to stand. After a week, the ring acquires about 50% of its basic strength, and becomes fully usable after 28 days.

How are products labeled?

All reinforced concrete products are marked with an alphanumeric abbreviation generally accepted in the state. This allows you to quickly determine the size and scope of each individual element when purchasing.

Letter combinations are deciphered as follows:

• KS – wall ring, available for placement in confined spaces;
• KLK – module for creating drainage networks and local storm sewer systems;
• KO – fundamental support that ensures the stability of the well base;
• KFC – fragments for arrangement of collector networks and drainage communications;
• KVG – products for installing water wells and laying gas pipelines.

The numbers next to the letters indicate the height, thickness, specific gravity and internal diameter of the ring. Understanding these values, purchasing suitable reinforced concrete products will not be difficult.

Before purchasing rings, you need to decide on their sizes, as well as select additional equipment for installation - support, bottom, ceiling

Additional elements for wells

Regardless of the purpose of the well, it will not be possible to get by with rings alone during installation.

In order for the entire system to function correctly and not fail in the future, the following elements will certainly be needed:

1. Base slabs (bottoms) - are placed at the base of the structure, level the base surface and give stability to the entire well shaft.
2. Support floors – are a concrete circle with a hole closed by a standard manhole cover. They take on and evenly distribute the external load over the surface. They ensure the safety of the entire well and protect it from collapse and cracking.
3. Additional rings – have a standard diameter, but less thickness. Designed to raise the current height of the well to a higher level.
4. Well hatches (lids) – are produced in the shape of a regular circle. Depending on operating conditions, they are divided into sidewalk and highway. They are characterized by high strength and good resistance to intense loads.

The presence of additional accessories ensures complete tightness of the system, prevents sewage from entering the network, protects pipes from freezing in winter and extends the service life of communications.

To equip and protect the well from destruction, you will need a base plate. For use in private construction, a product that can withstand a load of up to 1,000 tons is suitable. At industrial facilities, highways and streets with heavy traffic, reinforced modules that are not afraid of the current pressure of 1550 tons will perform better

All additional elements must be selected based on the conditions in which the system will be operated. This approach allows you to create a stable, sealed network with a large working resource.

Advantages and disadvantages of reinforced concrete products

Well rings made of reinforced concrete are very popular and are included in the list of the most popular building materials. This is due to their specific physical and structural characteristics.

The main advantages of the product include:

• Extended operational period. Concrete reinforced with steel wire is neutral to any environment, including aggressive ones, and, according to manufacturers, can last at least 100 years.
• Maintaining rigidity and structural integrity on active soils. Wells made of reinforced concrete rings are installed even in areas with seismic activity up to 8 points.
• Wide range of models. Products are available in a variety of sizes. This makes it possible to select suitable reinforced concrete products for any purpose and need.
• Pronounced frost resistance. It is ensured by a strong bond between the reinforcing elements and the concrete mixture, which occurs after the final drying of the workpiece.
• High tightness. The seams fit tightly together at the joints and prevent groundwater and other foreign substances or materials from penetrating inside.

Finished products are sold at the best price and are suitable for arranging communication networks of any scale.

In the process of producing a well from reinforced concrete rings, it is necessary to strictly adhere to the installation rules. Incorrect installation will lead to uneven load on the walls and in the future will provoke the appearance of cracks throughout the pipeline

Disadvantages include the weight and dimensions of the product. Transportation and installation require professional equipment with good power and a team of craftsmen.

This inevitably entails additional material costs and an increase in the total cost of installation work.

You can make reinforced concrete rings for installing a small well in your country house with your own hands. Homemade production technology is described in detail in next article, which we highly recommend reading.
