Well ring to 10 10 h

06.11.2019 Preparations

The arrangement of sewerage and wells is required condition in private and multi-storey buildings. Certain requirements are imposed on such facilities, so they must fully comply with sanitary and hygienic standards. In addition, when arranging a well treatment system for a country house, any person expects that the structure will last for decades, serving faithfully.

Therefore, the best solution for such work would be the installation of a concrete ring. This product is made of strong and durable material that can last almost forever, provided that the ring is correctly selected, the installation is carried out in compliance with all requirements. Therefore, it makes sense to consider the features of concrete rings, to understand the size range and installation methods.

What are the rings. Types and purpose

Well rings are reinforced concrete structures round shape used for the arrangement of utilities buried below ground level. Depending on the structure being constructed, the following types of rings are used:

Sewerage and water intake.

Products for laying underground cable networks.

Collectors.

Gas pipelines and water intakes.

In addition, there are such varieties on the market:

Rings with a flat and lock end.

Repair.

Additional.

Regardless of the type and purpose, products are made of heavy concrete, grades 200-500, reinforcement is performed.

Production technology

Rings are made for wells from hard concrete, which is poured into the formwork. It is necessary to clarify what is pre-made reinforcement from steel wire, with a diameter 8-12 mm. At opposite ends of the structure, two vertical rods are installed, which act as lugs for lifting the ring.

The mold is compacted by vibration to eliminate the formation of voids. The formwork is removed one day after the concrete is poured. After that, finished products are stored in open areas. The release strength of the ring ( 50% of the set) is recruited after about 7 days. The full strength of concrete is reached after 28 days.

Advantages and disadvantages of reinforced concrete rings

It is no secret that any building material has its strengths and weaknesses. This feature also applies to finished goods. Concrete rings seem ideal, but even they are not without some drawbacks.

The undeniable advantages of ZhB-rings include the following:

High quality at an affordable price.

Wide size range.

The ability to quickly equip the water supply and sewerage system.

High tightness: a tight fit of the seams prevents groundwater from entering the structure.

Long service life: reinforced concrete is neutral to any environment, so it can last at least 100 years old.

Rigidity of the structure: wells made of concrete rings can be mounted even on unstable ground.

Obvious disadvantages include the following:

Dimensions and weight: it is impossible to install a concrete ring without the use of construction equipment, which somewhat "weights" the cost of installation.

Lack of mobility: it is very difficult to move such a well.

It can be seen that there are more positive features, this explains the steadily growing popularity of concrete rings.

Marking according to GOST. How to read the conventions correctly

Each reinforced concrete ring has a marking that determines the scope of the product. Symbols comply with GOST standards, it looks like this:

KLK- products intended for the arrangement of a drain and urban storm sewers.

KVG- rings used for the installation of a gas pipeline and water wells.

KO - support ring that forms the foundation of the well.

KS- wall models installed in confined spaces.

KFK- drainage systems and collector networks.

In addition, the marking of the rings also contains numerical designations.

Decryption example:

KS-7-9. It means wall ring with wall thickness 70 and height 900 mm.

Standard sizes of reinforced concrete rings

Concrete rings are presented in a very diverse range of sizes. Standard sizes products look like this:

Height: 10-100 cm.

Wall thickness: 70-120 mm.

Inner diameter: 70-200 cm.

Specific gravity: 46-2 300 kg.

Thanks to these standard sizes, it is not difficult to choose rings for arranging an individual water supply system.

What else will be required? Additional elements

It should be noted that the installation of rings alone will not solve the problem of a quality water supply system. In order for the well to meet the requirements, installation of additional elements will be required. This is not a mandatory condition, but compliance with this rule will help prevent sewage pollution of the system, increase the service life, and give the structure a finished look.

For this apply:

Bottom plates - provide a solid foundation.

Floor slabs - thanks to a narrow hole, a small-diameter ring is installed on top of such a slab, which is closed by a conventional sewer manhole cover.

Additional rings - products of a standard diameter, but of a smaller thickness. Such elements help to raise the height of the well to the desired level.

The use of such products provides the well with maximum tightness, prevents pipes from freezing in winter.

bottom plates

Mounting process

In order for the well to meet the established requirements, the installation of the structure must be carried out in accordance with all the rules. Here you need to follow the well-known procedure:

Location selection

Water wells and drainage systems are not built close to residential buildings. Average distance from home - approx. 5 meters. There should be no groundwater in the chosen place, otherwise you will have to bear additional costs for sealing. In addition, special equipment must be free to drive up to the installation site.

foundation pit

For digging a pit, it is better to hire equipment: the depth of the pit should be equal to the height of two rings. Digging such a pit by hand will be very problematic. At the bottom of the pit, a drainage cushion is laid from layers of sand and gravel, with a thickness of at least 50 cm.

Rings

For the lower tier, a ring with a blank bottom is ideal, if the product is through, the bottom plate is laid first. The elements are installed on top of each other using a truck crane, the joint is smeared with mortar. If the well is mounted on moving ground, the joint can be reinforced with metal brackets.

After installing the rings, communications are brought to the well, the necessary connections are made, the pit is filled up, the rings are covered with an upper slab, and sewer manholes are installed.

Which manufacturer do you prefer?

Concrete rings for wells produces about 250 companies located throughout Russia. Consider 5 verified manufacturers.

LLC "MasterStroy". The company is located in Voskresensk, near Moscow, specializes in the sale of bulk and bulk cement, is engaged in the manufacture of pressure pipes and reinforced concrete rings.

neck rings By 10-10 are functional reinforced concrete products with increased resistance to harmful environmental influences. This category building materials has the form of hollow elongated cylinders inside. The diameter of the cylinders varies from 70 cm to 2 m, depending on the purpose, and the length always remains the same - 99 cm.

The scope of this type of rings includes such important engineering installations: sewer channels, heating and drainage networks and communication collectors. All of the listed structures are classified as typical prefabricated installations and must meet strict quality standards. So,rings By 10-10 have increased frost resistance (can be used at temperatures down to -40 degrees) and excellent strength. Subject to all production, storage and transportation standards, they easily withstand temperature changes, humidity, typical vertical and horizontal loads.

Deciphering the product label

The marking of reinforced concrete products consists of alphanumeric designations, each of which carries a certain semantic load. The brand is applied directly to the surface of finished elements with indelible black paint. It indicates the type and dimensional characteristics of building materials, and therefore it should be easily visible, both during storage and during transportation. Mark of typicalneck rings By 10-10 decoded like this:

1. TO – neck ring;

2. 10 - diameter in dm .;

3. 10 - height in dm.

In addition to those listed, the following data is also indicated during marking: date of issue of the batch, name or logo of the manufacturer, selling weight of the element.

Main characteristics and manufacturing

The main standard governing the manufacture of neck ringsBy 10-10, stands Album PS 192 . General standards prescribe the production of such building materials exclusively in the conditions of specially equipped plants using the formwork method. The process is divided into several stages: preparing the formwork of the desired shape and size, laying the reinforcing frame and all additional metal elements, supplying the concrete mixture. After the resulting raw material is subjected to heat treatment, cooled until completely hardened and removed from the mold.

As for the materials for manufacturing, the same high requirements are imposed on them. The strength grade of concrete is taken at least M200-M300, high-carbon steel of classes A-I and A-III is used for reinforcement. Welded metal meshes and embedded parts are treated with anti-corrosion oily substances. For their connection, the method of contact-spot welding is used. The reinforcing elements must be covered with a protective concrete layer of at least 15 mm. Compliance of all parameters of the finished materials with the project is checked during the final tests.

Well neck rings By 10-10

Not a single reinforced concrete well can do without well rings - well mouths. Prefabricated concrete wells on underground pipelines are part of a complex system that provides engineering communications with protection. Well neck rings By 10.10 are used to implement hundreds of standard solutions, so their production and price always at an acceptable level. To fix the well shaft, the rings are welded in 4-6 places with steel brackets. The stamp was issued according to the sketches of PI "Mosinzhproekt" and GOST 8020-2016.

The concrete ring is the main element of the construction of the wells; the installation of the ring is carried out after the installation of the chamber. Ring K 10-10 is placed on the cover of the well chamber (PC plates) and the neck rises by stacking the required number of rings. Well shaft ends base plate at ground level. The necks are assembled by welding steel staples. The design of well rings is simple - a frame made of steel reinforcement 6-10 mm thick, covered with concrete and shaped like a ring. The margin of safety of the rings allows you not to worry about the integrity of the well shaft. In the production of K 10.10 rings, laboratory and field tests of batches are carried out, so the reinforced concrete products have a high load-bearing capacity and guaranteed strength. Rings for wells, prefabricated reinforced concrete sold individually or in batches, the cost of products directly depends on the price of steel and concrete. Production methods and technical requirements for reinforced concrete products for rings GOST 8020-90"Reinforced concrete products for manholes". To withstand loads from the ground, manhole covers and upstream rings, well rings reinforced with frames made of hardened steel of class At-IIIC and At-IVC and A-I, A-II and A-III. Temporary ring loads correspond to schemes H-30 and NK80 in Album RK 2201-82.

Certified by GOST reinforced concrete rings have a high degree of anti-corrosion protection and hydrophobization. The mass of the ring is 680 kg and requires installation using special devices. For lifting and mounting rings K 10-10 have included mounting eyes.

Product marking

Well rings in the Album

RK 2201-82

are indicated by the letter K and the diameter of the conditional passage and the height of the ring in decimeters.

Approximate marking of the ring K 10-10 (1160x1160x990) looks like that:

K - ring-mouth of the well;
10 - nominal diameter;
10 - the height of the ring.

Reinforced concrete well necessary for access to the pipe system for the purpose of repair, installation, control and inspection. Such wells are arranged on storm sewers, domestic sewers, water pipes, drains, gas pipelines and some private systems. Reinforced concrete wells these are always prefabricated structures, consisting of rings, well chambers, floor slabs, base plates, etc. Therefore, production requirements, working drawings and design schemes of wells are included in entire albums. Thus, the Album RK 2201-82 included a number of standard engineering communications projects recommended for the construction and reconstruction of facilities in Russia. The price of reinforced concrete rings small, which is why prefabricated construction is so fast and popular.

For the manufacture of concrete rings K 10.10 is used heavy concrete M300 (B22.5), which tolerates operation well in the ground and is not resistant to cracking under pressure loads. The grade and configuration of concrete for well rings is selected taking into account seasonal temperature changes and frosts. Often such well rings used for private construction of small wells in household plots and in their own homes. The water resistance of concrete of W4-W6 well rings is a high class, which provides resistance to regular exposure to moisture and aggressive environments. Rings have low water absorption and can for a long time interact with liquids. For the use of rings in aggressive soils, special sulfate-resistant or other cements are used that tolerate chemical environments well.

Frost resistance well rings F150-F200, so they work in extreme conditions without losing strength. Well necks v a wide range You can find it in our "Reinforcement Handbook".

Product quality control

A high-quality well shaft for your communications is possible only from original and certified concrete products. Reinforced concrete well rings should not have cracks, reinforcement exposures, chips and dents. Minor shrinkage cracks and small deviations in geometry are possible, not more than 5 mm in thickness, 6 mm in diameter. The surface of the rings K 10-10 does not allow large shells, chips, sagging.

Acceptance tests reinforced concrete rings K 10.10 are carried out to check the indicators:

class of concrete in terms of strength and tempering strength of concrete;
conformity of reinforcing and embedded products;
strength of welded joints;
thickness of the protective layer of concrete to reinforcement;
accuracy of geometric parameters;
concrete surface quality.

Together with a batch of rings you will receive a factory technical certificate, which should contain information about the date of manufacture of a batch of concrete rings, the number of products, the results of strength tests, information about the brand of concrete and compressive strength, as well as the class of concrete for frost resistance and water resistance.

Transport and storage

Reinforced concrete well rings should be stored in stacks in working position (face up). One stack should not be more than 6 rows, in order to avoid falling and deformation of products. For transportation, wall rings are stacked in a stack no higher than 2.5 meters and securely fastened. Both during transportation and storage between the rings there must be gaskets with a thickness of at least 40 mm.
