Concrete rings for sewage: sizes, prices and application of products

In this article, you can familiarize yourself with all the features that concrete rings for sewage have: sizes, prices of elements for creating a system, their properties, advantages and disadvantages. The text contains recommendations on the selection of components with optimal parameters and tips for building a sewer system with your own hands based on them.

Concrete rings for sewage: sizes, prices and varieties

In private and suburban construction, sewer systems based on concrete rings are often used. This type of sewage system is considered one of the most economical. After all, the price of concrete rings for sewage is low, and the process of their installation does not require a lot of time. As a result, the owner of the suburban area has the opportunity to create comfortable living conditions outside the city.

Along with bricks and polymer rings, concrete elements are also used for the construction of sewage systems in the country without pumping out. Each of these materials has its own advantages and disadvantages, however, concrete structures significantly exceed the parameters of other system options.

Brick is less durable and requires a significant investment of time to make masonry, in contrast to ready-made elements, which just need to be placed on the bottom of the pit and fixed. In addition, it is extremely difficult to make wells of great depth on the basis of brickwork. The cost of a sewage system made of turnkey concrete rings is not much higher than the cost of manufacturing a brick system. Taking into account the simplicity of installation work and the minimum time required, such a small overpayment is quite justified.

Prices for the installation of a sewage system made of turnkey concrete rings:

Number of rings	Capacity, m³	Number of consumers	price, rub.
3+2	3,5	1-3	35990
3+3	4,2	2-4	39990

Note! Wells practically do not experience serious pressure or stress. Only aggressive environment and water act as destructive factors for concrete.

Advantages and disadvantages of using concrete wells for sewage

Many summer residents prefer to buy concrete rings for the sewage system to equip the system at their summer cottage, the prices of these products are far from the only advantage that confirms the benefits of such a purchase.

Advantages of concrete structures:

• the possibility of installation in areas with any type of soil (due to the increased safety margin, concrete rings are able to withstand the natural pressure that is formed in the process of displacement of groundwater or seasonal movement of soil);
• possibly the use of any materials for waterproofing;

• even if it is supposed to do the installation work with your own hands, this process will not take too much time;
• due to the flat inner surface, the speed and quality of cleaning concrete wells increases;
• the material is more affordable than brick or stone;
• long service life without the need for repair work.

A wide variety of sizes and prices of concrete rings for sewage allows you to create septic tanks of any capacity and depth. This type of material is highly hygroscopic, so contaminated runoff can partially seep through the walls into the surrounding soil. However, this problem can be easily solved with waterproofing.

The main types and overall dimensions of sewer rings

There are two types of concrete products for the construction of sewage systems on sale:

1. Additional (from 670 rubles).
2. Wall (from 990 rubles).

Wall type elements are used to form the neck of the structure. Additional options for products have an extended range of sizes, and non-standard ones. They are used in cases when the height of storage tanks cannot be formed according to the project from elements with standard dimensions. With the help of additional rings, you can adjust the height of any septic tank design.

The concrete rings used for the construction of the country sewage system are elements of the correct rounded shape. The inner diameter of the products ranges from 70 to 200 cm. The standard wall thickness is 70-100 microns. Most often, for the manufacture of drain pits and country septic tanks, a size of 1-1.5 m is used, the price of concrete rings of this diameter is 1500-2500 rubles. for the product.

For the manufacture of rings, manufacturers use metal reinforcement and concrete grades with different characteristics. Metal, as a reinforcing component, increases the strength of products and reliability. In addition, the possibility of stretching the structure made of rings is excluded. In turn, concrete provides corrosion protection to the metal. As a result, the design of the septic tank does not undergo deformation changes under the influence of compressive loads.

Note! High-quality reinforced concrete elements for sewers are manufactured in accordance with the requirements of GOST 8020-90. Therefore, in the process of choosing products, it is worthwhile to study in detail the instructions and manufacturer's data.

The main types of reinforced concrete rings for sewage, sizes, prices

Manufacturers produce different types of rings. Each type of product has its own parameters and a specific purpose.

Buyers can buy concrete rings for sewage of the following types:

• elements without a lock;
• filtration details;
• elements with a dead bottom;
• components with a lock connection or with a quarter.

 

How much are concrete rings for wall-type sewage without a lock

Wall rings for septic structures without a lock are considered the working part of the collection system. This section of the sewer is formed from three elements, including wall, support and additional type products. The dimensional parameters of the rings, as well as their number, are selected in accordance with the design data. Manufacturers mark products of this type with a combination of the letters "KS".

Straight rings without a lock are installed one on top of the other. The joints are treated with cement mortar, which fixes these elements. It is allowed to use special brackets to secure these rings.

Buying rings for sewage: how much do products with a lock connection cost

Rings with a quarter or a snap connection greatly simplify the process of assembling a well. The result is a tight and reliable connection of parts without additional treatment of seams with a sealant. In addition, the special structure of these elements allows compact storage of products on the construction site.

Special recesses are formed at the bottom of these parts. There are projections at the top of the rings. This specific structure allows the elements to be pushed on top of each other during installation. As a result, the rings are securely fixed using a lock connection, which eliminates the possibility of the septic tank structure sliding or displacement. After installation, the elements will retain their original position throughout the entire operational life.

Assortment of reinforced concrete rings for sewage: prices for filtration products

Filter rings for the construction of septic tanks are concrete elements covered with perforations. In other words, the surface of the product is covered with a plurality of holes of the same size. They are evenly distributed around the perimeter of the ring at an equal distance from each other. Through these holes, water purified in a septic tank enters the soil. On the basis of these elements, filtration wells for sewerage are designed.

To fix the drainage rings, special H-shaped fasteners are used. They are made of metal and securely fix structural elements in case of ground movement. To fix a pair of rings together, you will need about 3-4 fixing elements.

At what cost can you buy reinforced concrete rings for sewage: prices of products with a dead bottom

Well elements with a dead bottom in the form of rings are used for the construction of sedimentation tanks. In this part of the sewer system, sludge gradually accumulates during operation, which can be removed using a fecal pump for sewage in a private house or special equipment equipped with equipment with similar functionality.

This type of product is considered by experts as the best option for construction autonomous, as well as an overflow sewer system for waste treatment.

Do-it-yourself sewer installation in a private house made of concrete rings

The construction of a system of concrete rings, like any other sewage system, is carried out in stages.

The work sequence is as follows:

• selection of a scheme for construction;
• calculation of the capacity of the well, taking into account the number of residents;
• choosing a suitable place for installing a septic tank;
• formation of a pit of the required size in accordance with the calculations;
• installation of concrete rings;

• pipe system supply;
• sealing seams between parts and joints;
• falling asleep of the structure.

Calculation and selection of a sewage system from concrete rings

A sewerage arrangement scheme based on concrete rings may provide for a septic tank with one, two or three chambers.

If a small number of people live in the house, it is better to choose a single-chamber structure for construction work, including a drainage well and a sump. Two-chamber systems are used when there is a large amount of plumbing equipment in the house, for example, a bath, sinks, a toilet, a washing machine, a dishwasher, etc. In this case, the sewerage system will consist of two tanks and a drainage well.

The scheme may also include points for placing concrete storm sewers, which are installed around the perimeter of the blind area of ​​the building and in other problem areas where liquid can accumulate after heavy rainfall. This system will protect the relief of the site and the foundation of the building from erosion by water.

The optimal scheme should take into account all the calculations necessary for comfortable use, in particular, the capacity of the well. This indicator depends on the daily water consumption of the residents of the house. The average amount of fluid intake per person per day is about 150-200 liters. To calculate the optimal volume of a septic tank, this indicator must be multiplied by the number of people living in the house on a permanent basis. To the result, you need to add 20%, which will cover unplanned overruns and storm sewers.

Note! According to building codes, a septic tank with an optimal volume should contain drains consumed within three days.

To find out the number of rings required for the manufacture of a septic tank, you need to divide the total volume of the sump by the volume of the concrete product.

Preparation of a site for the construction of a sewage system for a private house made of concrete rings

After the sewerage scheme has been drawn up and calculated, a place for installation is selected wells.

In this case, it is worth considering certain requirements:

• the minimum allowable distance between the house and the septic tank is 10 m;
• the level of movement of groundwater should lie below the mark where the bottom of the well will be located;
• the minimum allowable distance between the drinking water source and the septic tank is 50 m.

The building area must be cleared of debris and stones. Next, a pit is dug, the size of which is able to accommodate a drainage well and a septic tank with a margin of 30 cm on each side. In those places where the storage chambers will be installed, concrete pouring should be performed. Thus, the penetration of the waste liquid into the soil and its contamination is excluded. Then it is necessary to form a drainage layer in the form of a sand cushion. The recommended thickness is 30-50 cm.

As an alternative to concreting, concrete rings equipped with a blind bottom can be used. These products will protect the surrounding soil from sewage pollution.A cushion consisting of gravel, rubble and sand should be formed under the drainage well. Its minimum thickness is 50 cm.

Recommendations for installing concrete rings for sewage with your own hands

Even if the sewage system is made by hand, the installation of heavy concrete rings cannot be performed without the use of lifting construction equipment. The elements are alternately stacked on top of each other and fastened with metal brackets, plates or mortar.

At the next stage, the overflow between the tanks of the system is organized. For this, pipes are supplied. To connect the storage tank and the main, it is necessary to punch holes in the concrete rings for the installation of the pipeline and tees. It is desirable that the sewage system functions as a water seal. To achieve this, you will need to install the line by bending.

For waterproofing concrete sewer rings, it is better to use a product with a water barrier. All joints are processed with this solution. For external sealing, waterproofing agents of the fusing or coating type are suitable. The use of liquid glass is allowed. To improve the level of waterproofing of a septic tank, experts recommend buying plastic cylinders and placing them inside the well.

The finished structure of the well made of rings is covered with a special concrete slab. Some product options have the ability to install sewer hatches. The average cost of slabs with hatches is 1500-3500 rubles. This completes the process of assembling a well from concrete rings. It remains only to fill the pit with the structure with soil, adding a large amount of sand to it. If this is not possible, the recess is filled with soil removed from it earlier.

After that, the system is completely ready for operation. Subject to compliance with all the requirements of the assembly technology, such a sewage system can serve for several decades and provide living comfort for people in their summer cottage throughout this period.
