Description
Removing excess water from a specific surface and passage and location, removing underground water, runoff by pumping or gravity flow is called drainage. Drainage is carried out in two specific fields, one of the civil and construction industry to remove excess water from the path of the structure, and the structure, and the other is to control the water level in agricultural fields to control the minerals in the soil and maintain the quality of the soil. Drainage in the past was done with traditional methods, using cement pipe, stones and leaves of trees. In Iran, drainage was done during the Achaemenid period, but in the contemporary period in the Khuzestan, in the faculty of agriculture, and later, using thin-walled polyethylene and P.V.C pipes. It used to be that the pipe was drilled and grooved according to the need.
What is a drainage pipe?
The best method for drainage is piping, many of the old traditional drainage methods have been by making man-made pits and channels out of clay and mud and recently cement.
Drainage with new methods was using P.V.C, polyethylene, and iron pipes that drilled by plumbers, and preparing these pipes was a difficult and time-consuming task, and of course, it had a lot of costs and no definite moisture. Polyethylene pipes were better than all methods because they are in coil form and it is possible to carry 100 meters of pipe in one coil and it is easily pierced, but any way, piercing polyethylene pipes is expensive and takes more times. Recently, drainage pipes are produced from P.V.C material, they are very light, they are perforated and ready to use.
P.V.C drainage pipes
The production of drainage pipe is very precise. First, the pipe is produced using P.V.C materials by extruder method, and then according to the customer’s needs, semi- reticulate or full reticulate is prepared in certain formats, and if there is a need to cover, the fibers it is woven around the pipe using modern textile methods.P.V.C drainage pipes are very flexible and light, but they cannot withstand a lot of traffic load; for this reason, they are installed at a high depth and granulate stones and sand are placed on them. In cases where it is necessary to withstand a lot of traffic load, polyethylene carrugate pipes are used, which are drilled with the help of a drill or a milling cutter.The use of drainage system is very important, if the water remains in the agricultural land and the volume of water is not properly controlled, it will cause serious damage to the agricultural system. If the water remains in the path of the buildings and is not removed properly, the water destrings the building, it is also very vital for the walls and brigades because it leads to the collapse of the wall or brigade.
Drainage has a very small cost compared to other costs in construction, if the drainage is not done accurately and correctly, the water stays in the path of walls, brigades and buildings causes a lot of damage to the infrastructure.
The price of the pipe is very suitable considering that it is a light pipe; on the other hand, this pipe does not need to be drilled and the cost of transportation and implementation is very economical.
Buying a drain pipe is very easy; it is enough to specify the size of the pipe first, then specify whether you want it to be covered or whether you want to cover it without cover using stoned and sand, and finally determine which type you want between the two types of full reticulate or semi-reticulate you want.
Drainage pipe standard
Drainage pipes are produced based on DIN1187.Standard and national standard 7669.An important point in maintaining these pipes is not to collect oil and derivatives with these pipes. covered pipes were first used by the Germans in1960, which was very effective in the development of these industry later. The use of these covers made it unnecessary to lay the trench and the project costs were greatly reduce.
