Laying of sewer pipes in the ground.Technology

Selecting materials

From internal piping wastewater transported by the external to the reservoir tank or septic tanks.To this function was carried out at the proper level, it is necessary to ensure the correct laying of pipes.

most often to mount the sewerage network using polymer pipes made of polypropylene, polyethylene and PVC, painted in orange color.

the presence of dynamic forces exerted on the pipeline network.It should select corrugated plastic pipe consisting of two layers of material.Connection is made by means of fittings, normally in the funnel.Such piping is less subject to corrosion, durable, and thanks to the low surface roughness of the walls do not create blockages and fouling.They lay at a depth of less than 3m.

sequence of laying pipes

1. Earthworks.First, you need to properly dig a trench, but then begins laying sewage pipes in the ground.The technology of this process is as follows:
   • Determination of the depth of the trench - in accordance with the regulations, it must be greater than the depth of soil freezing in the winter, as well as to consider the location of groundwater
   • Preparation trench - surface leveling floor, performed a bias according tocalculations (usually 1-2 cm per meter), is filled with a substrate of gravel 15 cm thick and its seal, as well as in moments of connection pipes and fittings made small pits
2. construction work.Lay the pipe should be started from the foundations of buildings:
   • Laying pipelines in trenches funnel down and cleaning their edges
   • blur the edges of a special substance, and installation of the pipe into the socket until it stops
   • combination of all the other parts

   For the convenience of work, correct and reliable pipe connections are kindly requested to measure the depth of the pipe entering into the socket and apply the appropriate mark.

   Turns on the main line constructed value of 15, 30 and 45 degrees.Every 15 meters of pipe equipped with the audit or the cleaning of.

3. backfilling is the final stage of construction, after the performed lining sewer pipes in the ground.filling technology provides a system check the slope angle after connecting all the elements.In order to fill the trench, the soil is used, formed in the process of excavation, which was previously crushed and gets rid of large inclusions.
   

   to backfill the soil may not be used, which contains stones or solid lumps larger than 30 cm, as they can damage the sewers.

   trench gradually filled with earth, each layer having a thickness of about 5 cm just ram embankments in the lateral pipeline.Above them spend ramming is forbidden, as it does not exclude the possibility of deformation or damage to the pipe.

Warming sewer pipelines

needing warming - it is usually those that are located above the level of soil freezing or the issues of domestic sewage.Usually used for this purpose polymeric insulation type stenofleks or Energoflex.Insulation is placed around the pipeline and is well secured with wire ties or.Only after the installation of insulation and verification bias network can be carried out backfill the trench.

recommended to pour over the insulation layer of sand thickness of 10-15 cm, and then fall asleep soil and tamp it in the same way as described above.

It should be remembered that the presence of damage to the sewage network it will be better not to change a single element that is out of order, and make a complete dismantling of the system.It will be more reliable and economical.

process that you can perform yourself - is the construction of the system and laying of sewer pipes in the ground.Its technology is simple, and if you implement all the recommendations outlined in this article, the life of the sewer system will be long, and its reliability - high.
