Sewage reinforced concrete non-pressure pipeline
As a matter of fact, pipes from asbestos-cement are not inferior to their metal counterpart in strength. They are resistant to various chemical influences, low temperatures and corrosion. Their installation is easy and simple, plus, asbestos-cement non-pressure pipes have good thermal insulation properties. A particular advantage is their price, which is very affordable. According to GOST, which defines the size, such non-pressure pipes can be in diameter from 100 to 500 millimeters.
They are used as drains and drains in non-pressure sewage systems. In addition, asbestos-cement pipes are used for laying communication cables, chimneys, garbage chutes and electric wires. Also, often used by builders as a fence, cellar and other structures.
Comparison of tubing with other
Another alternative installation of a sewage non-pressure pipeline, can be the installation of tubular pipes. They are installed at a certain depth below the ground, where they can transport:
- wastewater from atmospheric water;
- of groundwater;
- household fluids, non-corrosive to concrete and rubber, which acts as a sealant;
- production fluids.
They are made of heavy concrete using vibrohydraulic pressing technology. If you make a comparison with analogues, then the tube has a higher strength. They are characterized by high crack resistance, frost resistance and water resistance.
The internal surface of the socketed non-pressure pipes is processed by grinding, so they are technologically and easy to install, and also have almost complete tightness.
RC pipes are divided into three categories( distance to the top of the pipe), relative to strength:
- up to 6 meters;
- up to 4 meters;
- up to 2 meters;
The bearing capacity is greater due to reinforcement, while the wall thickness remains the same for a single diameter.
Polymeric materials as non-pressure drainage pipes
PVC pipes are used almost everywhere and are famous for their following performance properties:
- Chemicals;
- Not subject to corrosion;
- Characterized by long service life;
- Easy to install;
- Easily transported.
- Relatively low cost.
Thus, they occupy a significant place in the construction market. In the municipal economy, such pipes are used in large quantities for construction and other needs. Speaking objectively, pipes made of polymer can be considered the basis of house sewer networks. They are mounted in the bell, with no special equipment required. At one end of the pipeline there is a bell, with which the ends are connected.
Non-pressure PVC pipes are divided into two types:
- Three-layer;
- Monolithic.
Depending on the rigidity, they are classified into the following classes:
- SN2 - set to a depth of 1 m;
- SN4 - up to 6m;
- SN8 - up to 8m;
- SN16 - up to16m.
By design, polymer pipes can be divided into:
- Corrugated - designed for drainage.
- Spiral-shaped - used for the organization of a technical sewer system and stormwater.
