The sewer system is a set of wells, drives, pipelines and other structures that ensure the collection and removal of wastewater, which are formed by people’s life, atmospheric precipitation and production waste.
Sewerage is internal and outdoor. This system includes biological, chemical or mechanical treatment facilities, which in turn are divided into local and industrial treatment facilities.
Installation
If we talk about the installation of the sewage system (especially for the organization of networks of large objects), then the following important point cannot be noted: only real specialists should be carried out, within the framework of the existing requirements.
From a technical point of view, the installation of the sewage system consists of the following stages:
1. Organization of channels.
2. Heat – and waterproofing, seaming of the seams, installation of gutters under pipelines.
3. Invot the required pipelines, connection to the water treatment system.
4. Laying soil, concreting.
The main recommendations
Now let’s give a few recommendations for the installation of the sewer system.
* You need to make sure that the firm from the outer network plastic is 4-5 mm lower than the level of the adjacent surface.
* In places of action on the channels of horizontal forces (for example, in concrete areas), an expansion seam should be provided, which should be on the 2nd sides of the channel line, according to the standards of Din 18318.
* With competent filling of a concrete pillow, laying a prayer surface or asphalt, dynamic loads, the reliability of the sewage system is ensured due to the strength of the side walls of the plastic canal
* In places where the outer sewer is installed in a prayer surface, along the channel line, the expansion seam must be filled with bitumen or mineral mastic. In the case of installation of areas with large load classes, any dynamic forces acting on the prayer should not have direct influence on the side walls of the canal. These forces must be compensated using a monolithic structure: say, by laying the first three rows of paving stones in a special concrete pillow.
* In places of maximum axial effort to sewer systems (for example, where there is a significant slope of the site), it is necessary to follow additional caution measures and recommendations during installation. It makes sense to seek help from the employees of the company to which you have entrusted the installation.
