Main characteristics and dimensions of concrete sewer rings

In order to equip an individual sewer system in your own country house there are several ways. But despite the huge range of more modern and newest building materials, reinforced concrete rings are in the greatest demand. Such popularity has been achieved due to the durability, reliability, and frost resistance of such products, as well as the dimensions of concrete sewage rings.

The main characteristics of concrete rings

The use of precast concrete structures in the production of construction can significantly reduce the time of production work, while increasing productivity. It is the rings that are considered the product most often used in construction processes.

Application area

The scope of use of such products can be very different:

• The construction of drinking wells;
• Arrangement of manholes necessary to monitor the status of communication systems;
• Construction of septic tanks;
• Arrangement of storm sewers, etc.

Advantages and disadvantages

The advantages of structures of this kind include:

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

But there is one major drawback, which lies in great weight. For example, the answer to the question of how much a concrete ring with a diameter of 1 meter weighs becomes a value equal to 600 kg. And this suggests that the transportation of such a product to the building site is impossible without special equipment.

Dimensions of structures

Dimensions weight of concrete rings - these are two parameters directly related to each other. As the weight, so the overall parameters of such products may be different, depending on the type of product being created and the purpose of its use.

To date, there are rings of the following sizes:

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

Note! Marking of the product consists of the letters KC or KS and 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 products that are called complementary.

Such products can differ from typical ones according to the following parameters:

• The shape of the design itself;
• Wall thickness, which varies from 65 mm to 115 mm;
• The presence on the surface of the locks, which allow to simplify the process of assembling the structure;
• Height;
• Dia.

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

Council The advantages of using reinforced concrete structures of square shape include the possibility of installing them on a concrete slab. This eliminates the need to build a concrete screed at the bottom of the well, and besides, digging a square hole is easier than a round one.

Types of rings

By type of construction of this kind are divided into two main types:

1. Straight lines. The connection of such rings is made with the help of metal brackets and cement mortar;
2. With a lock - such products are endowed with an annular protrusion in the upper part and a notch in the lower part. Placing such elements on top of each other allows you to create strong connections, which eliminates the possibility of displacement.

Manufacturing technology

A serious load on the products of this kind during their operation necessitates giving them high strength properties. That is why the production process uses only high-quality fine-grained solution. Usually it is concrete belonging to the grades from M200 to M500.

The manufacturing process is divided into the following steps:

1. Fill form is being prepared;
2. The reinforcing framework keeps within a form;
3. Filling is done with ready-made concrete mortar;
4. Void is removed by vibration.

Now the product remains dry in the appropriate microclimatic conditions.

Making rings at home

If you decide to make reinforced concrete rings with your own hands, then by all means you should know:

• To obtain a quality product, you must use cement brand M400 and above;
• Washed quartz sand should act as a fine filler;
• A large filler is low-gravel.

Instructions for making products of this kind at home are as follows:

1. Arrangement of formwork. You will need to build 2 cylinders, of which 1 for the inner diameter and 1 for the outer.

Council Boards, plywood, a roofing sheet, etc. can act as materials for the manufacture of formwork.

1. Choose a flat area and install on it the inner and outer cylinders, so that the walls of the products are equidistant along the entire circumference;
2. Along the perimeter of the formwork at equal distances, place 10-12 metal reinforcing bars with a diameter of 8-10 mm;
3. The resulting frame must be secured with wedges that will move up as the mold is filled with the solution;
4. In order to easily separate the finished product, lubricate the walls of the mold with used engine oil;
5. Pour a layer of concrete in the form of about 10 cm and tamp with a metal pin by piercing. So fill out the entire form;
6. Cover the formwork with thick cloth to protect it from the sun;
7. After 3-5 days, the formwork can be removed and the product left to dry for another 7-14 days, covering it from the sun and moisturizing it several times a day.

Construction of sewage from concrete goods rings

Sewage installation technology involves the process of concreting the bottom of the well in order to prevent the ingress of waste water into the soil.

Council On the modern market, you can find rings immediately with the bottom. This design will prevent the flow of wastewater, as well as the penetration of groundwater into the sewer concrete wells.

In addition to the need to isolate the bottom of the well, you also need to waterproof the joints between the rings.

The following building materials can be used for this purpose:

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

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

Finally

Concrete rings are prefabricated structures that are in demand on the modern market for various purposes. Regardless of what object you are going to build, in the modern construction market you will certainly be able to find structures that are suitable in size and shape.

But if such products are still not found, you can easily make them yourself, because this process is simple and will save on transport work. A video in this article will reveal to you even more interesting information about what are reinforced concrete rings.
