Drainage — the technical system intended for charge the underground waters and their branch accumulating in soil for the territory of a site. In the location and solvable problems of system of a drainage are divided into a superficial drainage which is equipped on a site at some distance from buildings and a drainage of the bases thanks to which it is possible to secure house basements against penetration of ground waters.
Drainage pipes — the part of a design of a horizontal drainage which is carrying out function of the water reception and water taking away element. Drainage pipes apply in systems of the closed drainage of farmlands, in drainages of constructions in other special drainages (against landslide, mine, etc. ).
Recently two - layer corrugated pipes of an izpolietilen are most widespread.
Polyethylene drainage pipes, possess a uniform structure, high corrosion resistance and durability. Stack drainage pipes end - to - end to each other, connecting special couplings. Drainage pipes have punched openings (perforated or slot - hole openings) through which water arrives. Make pipes on special machines and devices by an extruding method.
For what the drainage is necessary?
Even if in the course of construction there are no signs that ground waters can leave close to a surface, the drainage is necessary.
At construction of the building holes rummage, soil is loosened, all this facilitates water inflow.
As a result can happen so that in the absence of a drainage after the first serious heavy rain the cellar of the building will be flooded with water in spite of the fact that in a radius of several kilometers there are no reservoirs.
There is nothing worse, than the water which is washing away the base of the building. When freezing it destroys its structure, and cracks appear. It is possible to overcome this misfortune only by means of correctly made drainage.
