Geocomposite Drain Pipe is made of plastic core and outer filtering cloth. In the state of hot melting, it is formed into three-D network structure. It has two shapes: rectangle and round. This kind of pipe has some advantages: good drainage, high pressure resistance, light weight, so it is very popular in some projects.
Application of Geocomposite Drain Pipe:
1) Highway and roadway subgrade
2) Retaining wall
3) Landfill
4) Roof garden
5) Building foundation
6) Underground irrigation
Flexible permeable hose is supported by anticorrosive spring rings to form an anti-high pressure structure.Besides, an additional non-woven cloth works as a filter to prevent the sand and soil from going into the pipe,thus purifying the water. Terylene threads on the outside surface enables the pipe to have a good sopping capacity and c ollect the superabundant water in the soil system. The rubber tendon enables the pipe wall to integrate well with the spring steel circle so that a omnidirectional penetrating function is realized, with the impurities like bedloads blocked out. In this way, penetration, filtering and drainage are done at the same time.
