Soft Permeable Tube is made of the frame struction composed of PVC plastic steel wire, which can fliter totally and drain groundwater with high speed and efficiency. With high permeability and big tonnage, it replaces traditional PVC punch-tube for water seepage. Convinent to use with high efficiency.
Application:
1.Drainage in airport, railway, highway, playground and park greenland;
2.Drainage system of mine coal deport,boiler plant garbage depot and langfill waster site;
3.Drainage of tunnel, retaining wall, road foundation and road;
4.Drainage of places such as farmland low-level bog and roof garden irrigation.
