Types and sizes of well concrete rings

Concrete rings are used in the arrangement of water supply systems for residential facilities and summer cottages, gas pipelines, inspection, waste and sewer systems, in the industrial and domestic sphere. Design features of products:

  • additional;
  • wall;
  • prefabricated;
  • with a quarter;
  • bottom;
  • with lids etc.

Ring types

Additional elements are used provided that the sizes of standard rings do not fit. Supporting (auxiliary) structures contribute to the construction of objects that are not a multiple of the height of standard well rings. The sizes of the rings correspond to standard products, but differ in their lower height. Products are made to order.

Reinforced concrete through structures perfectly cope with their tasks in the arrangement of drainage, sewer, network water and gas wells. Product diameter: 70 cm, 1m, 1.5m, 2m, 2.4m, 3m. Height: 30, 50, 60, 90, 120, 150, 180, 200 cm.

Wall devices provide the creation of a neck, they are used for all types of wells: sewer, water and gas. Size: D 0.7 x H 0.3 to D 2 x H 0.9, weight from 135 to 1500 kg.

To prevent the possibility of displacement of the rings after installation, special grooves are installed on them that do not allow the moment of displacement. To achieve maximum strength and durability, experts recommend giving preference to vibrated, steamed and reinforced products with a wall thickness of 10-11 mm, which do not allow water to pass through. Installing the first element with a bottom will provide an increased level of sealing.

reinforced rings

Reinforcement of the product is made by vibrocompression, similar to standard designs. After pressing, the products take on a dense and uniform appearance, allowing them to retain their shape and moisture resistance. When arranging reinforced rings, they are fastened with a cement mixture, contributing to the maximum reduction in water penetration into the soil. For the development of reinforced concrete rings, factory conditions are required. Advanced techniques help to obtain a perfectly even coating of structures and reliability in application. The cost of rings is determined by their diameter.

How to decide on the size?

The parameters of all elements of the well (rings, covers, bottoms, clamps and rivets) are determined by its type and purpose. The rings must have the same parameters (in length and cross section), the lid and bottom must have similar parameters in a horizontal section. To avoid confusion in the parameters of the rings, special markings are used. It allows you to find out the height and diameter of products.

Standard ring sizes:

  • cross section 700 - 2500 mm;
  • length 700 - 1200 mm;
  • walls 80 - 120 mm.

Additional elements with non-standard dimensions are developed by special order. The mass of the rings is determined by their dimensions. The smallest have a mass of 40-45 kg, and the largest - 1500 kg.

Attention! For the arrangement of drainage wells, reinforced rings will be an ideal option.

How are well rings marked?

To determine the parameters of the rings, the GOST 8020-90 rule is used, where the letter values ​​are indicated:

  • KS - rings for walls;
  • PO - floor slabs;
  • PD - panels for laying on roads;
  • PP - floor panels;
  • PN - panels for arranging the bottom.

Numerical values ​​determine the cross section and height of the rings (for example, KS 15.9 are rings for walls with a cross section of 1500 mm and a length of 900 mm).

Design features

The main components of wells include rings and covers, determined by their functional features.

Well rings contribute to the formation of the shaft and neck of the structure, the bottom and cover provide their strengthening. The diameter of the rings varies within 80 - 200 cm in increments of 50 cm, the height varies in the range of 70 ... 90 cm, structures with a height of 120 cm have the largest parameters.

For the arrangement of the water supply system, products of the KS8-7 marking are used, less often they use KS10-9 well devices. They do their job well when arranging shallow pits. Rings KS 8-7 allow you to increase the depth of wells. Maka KS 8-7 indicates less weight, which simplifies self-assembly.

For sewer systems, reinforced concrete rings KS10-9, KS15-9, KS20-9 are used. For revision and prefabricated engineering solutions, models KS15-9, KS10-9, KS8-7 are used. To carry out repair work (deepening) of the well, use the design KS6-7. Given the possibility of covering them with a hatch, the selected structures can serve as the neck of the well.

When creating a prefabricated well with a shallow shaft to accommodate the first ring and then deepening manually, it deepens under its own weight. The following components are laid on top of it until the specified depth of the well is reached. The areas for joining reinforced concrete rings are treated with a concrete mixture with further overlapping with a lid - a reinforced concrete slab with a hole. Well covers are marked: PP6-2, PP8-2, PP20-2-1, PP15-2, PP10-2. Their cross section varies within 1160 - 2500 mm, and weight - from 250 to 3000 kg.

Reinforced concrete cup - a ring with a bottom, presented in the form of a monolithic structure that provides the functions of the foundation. Products are marked with KCD.

Attention! When purchasing rings for a well, experts recommend giving preference to a brand of concrete from M500.

Additional elements

For ease of use and ease of installation, additional accessories are used. They can be supplied as a set when ordering rings or sold separately.

Dimensions of bottom rings (DK)

When arranging reinforced concrete structures, it is important to provide for the maximum level of tightness of the structure being mounted. This is facilitated by monolithic rings with a bottom. Outwardly, they are represented by solid products that prevent the possibility of accumulation of sewage, due to the presence of a lower monolithic element.

Lock ring dimensions

Monolithic structures are distinguished by the presence of a selection and protrusions at the top and bottom of the ring. This contributes to the ease of vertical alignment of parts and the prevention of horizontal displacement. A high level of moisture resistance is achieved due to the density of the interlock.

Quarter ring markings:

For example, the variant KS-15-9ch is considered, where

  • KS - through ring;
  • 15 - passage section;
  • 9 - length;
  • H - the presence of a lock (quarter).

Manhole covers (PC)

Based on the purpose of the well, a hatch opening is required, providing convenient access to engineering solutions. This is facilitated by cylindrical reinforced concrete structures, closed at the top with a lid with a hole for the hatch (made of cast iron or sand-polymer mixture).

Positive characteristics of RC cap rings include:

  • monolithic connection of the ring with the cover;
  • duration of operation provided due to the strength of materials (concrete mixture and steel reinforcing elements for the frame);
  • ease of installation.

bottom plate

The bottom slab is structurally represented by a monolithic reinforced concrete slab used for waterproofing the well. When buying a bottom, you should take into account the load placed on it. In some cases, the use of heavy grade concrete and reinforcement with reinforcement is required. The marking of structures is represented by letters (PN - product type) and numbers (PN7, PN10, PN15 and PN20).

So, the product PN 15 is used for wells with an internal cross section of 150 cm, and PN 10 for wells with an internal diameter of 100 cm.

Floor panels (PP)

Concrete panels with a rounded opening for mounting the hatch (made of cast iron or sand-polymer mixture). It provides access to water and sewer communication solutions. Floor slabs with hatches prevent contamination of wells and protect against accidental ingress of people into it. The dimensions of plates of different markings have different meanings, but the holes for mounting the hatch correspond to standard parameters. This allows you to equip the hatch, in accordance with regulations.

Floor slab grades:

  • PP10-2;
  • PP15;
  • PP20-1;
  • PP with a hatch made of a polymer-sand mixture (PP 10-2 with LPP).

Support ring dimensions (KO)

Installation of structures is carried out on the neck of the well, allowing you to bring the mark of the hatch with a cover to the design value. They are used in the repair and reconstruction of highways, allowing you to ensure that the level of road surfaces and the height of the well. The absence of support rings is only allowed when the well is located far from the highway and places where pedestrians move.

Houses for wells

The houses serve to provide decorative properties and prevent the formation of silt on the bottom, avoiding annual cleaning.

The house protects the water in the well from debris, allowing you to save money on installing filter systems. Sun protection prevents the growth of organisms and bacteria by preventing the water from heating up. In winter, it is excluded from freezing. A closed well increases the level of safety for the child.

The house has a shaft for a cable on bearings, which simplifies the process of extracting water from the well. The water tank is placed inside the structure, which allows you to get water at any convenient time. Galvanized houses are resistant to natural precipitation and have a long service life.

Attention! For the installation of houses, preliminary installation of an octagonal washer is required, which covers the upper ring.

Types of houses:

  1. steel;
  2. concrete;
  3. metal-plastic;
  4. from lining;
  5. forged;
  6. from a log house (oak or pine);
  7. from the blockhouse.

Production and installation

Well rings are represented by typical reinforced concrete products, developed in accordance with GOST 802090. The material for manufacturing is a concrete mortar used for arranging recessed structures in low-aggressive environments.

When choosing reinforced concrete rings, take into account the characteristics of the design. For example, elements for wells located on highways require equipment with floor slabs and hatches. To achieve a given level of moisture resistance of products, monolithic structures with a bottom are used. The connection of individual reinforced concrete rings is provided by metal brackets. Support products allow the well to be brought to a given level.

Installation of rings is carried out in one of the convenient ways:

  • construction option, using construction equipment for digging a pit;
  • non-industrial by uniform undermining of the soil around the entire perimeter of the structure.

When buying reinforced concrete rings, you should decide on the method of delivery. Modern manufacturers offer delivery by trucks and equipment with a crane for unloading and installing elements.
