Sewer pipes for outdoor sewerage

Basic inquiries to drainage pipelines

Basic requests for drainage pipelines

When construction works on all communication networks are underway, sewage pipes are always in use for laying both external and internal networks for drainage. Specific requirements for such systems can be clarified in regulatory documents, as well as on the calculation of discharge of runoff. Pipelines that are on the outside should fulfill these requirements:

  • Have good resistance to dynamic and static reactions.
  • After filling with soil, do not deform.
  • To be resistant to different types of loads( transport, people).
  • If the surface water changes, such pipes should not be dislodged in the butt joints.

During the construction of residential buildings, industrial facilities, the pipeline must be laid in trenches, and be excavated below the freezing marks of the soil. Such rules are prescribed in special GOSTAH, which are available today.

All quantities can be viewed in certain metrological services, they have all the data on construction work on certain objects. If the pipeline laying processes take place outside the city, then the installation depth is from 0.5 to 2 meters. It also depends on the terrain and the location of the house.

Basic requests for drainage pipelines

Sewer pipes for external sewerage crossing the most important road systems, must have a high degree of external load. To do this, use very strong pipes. Apply drainage systems, wrapped in corrugated materials. Such plastic pipes are highly flexible.

External piping systems and their material for the manufacture of

For good quality and installation of external drainage systems, it is necessary to pay attention to their frost resistance, corrosion resistance, as well as to the strength of the material being used, since the life of the device depends on this.

Very often steel pipes are used for external sewage, but they have a number of negative characteristics:

  1. They are very corrosion resistant and at least work well for several years.
  2. The throughput is not high. On the walls occur sediments, which reduce the passage of runoff through the system.

External piping systems and their fabrication material

Plastic pipes are also used, they are much better than steel pipes and have become an excellent substitute for them. They have a large range of positive characteristics, such as:

  1. Have good strength.
  2. Durability exceeds 2-3 years.
  3. Easy to carry.
  4. Installation work is very easy and not time consuming.
  5. For unstable systems, as well as for mobile soil, they are flexible.
  6. Also have good frost resistance and can be laid during the cold season.

External piping systems and their fabrication material

But such systems have a number of negative qualities, for example - it's low strength when laying them under a certain slope. To solve such a problem, it is recommended to use pipes with double walls or corrugated pipes.

Installation work

Installation works for outdoor drainage systems have such properties:

  1. Almost always in country houses pipes with a diameter of 100mm are used.
  2. To use a polyethylene connection, it is necessary to operate quite expensive equipment. Most often it is used for welding.
  3. Polyvinyl chloride pipelines are more advantageous for the device, and also less costly in choosing the equipment.
  4. It may be that the sewerage systems are laid, not very deep, for this they must be insulated so that there are no ruptures. If such a system is laid down below, then no thermal processes are required.

Installation work

External drainage systems for drainage drainage must be insulated so that there are no problems, for example, accidents, and the pipelines are not frozen, and they will still work well. This factor is very important and it is worth not forgetting about it.
