Soft previous pipe for drain
Soft previous pipe for drain is consist of tube, non-woven filter liner, and penetrated cover.The tube is supported by anti-rust spring coil to form a high anti-stress soft structure. The nonwoven filter liner can prevent sediment out of pipe, so as to achieve effect of water seepage.
The polypropylene fiber make the outer coating layer and the spring steel ring around the tube body into an organic entity which has a good omnidirectional permeable features.The penetration water can sink into the tube smoothly, and the sediment impurities are blocked outside, so as to achieve permeability, filtration, and drainage at the same time.
Product Features:
1 Small pore diameter , omni-directional filter ,excellent permeability
2 High tensile and pressure-proof ,long service life
3 With good property of corrosion resistance and erosion resistance.
4 Good integrity, less joints and easy to connect
5 Soft texture and good combination with soil
Application Field:
1 Drainage for road, railway, airport, high way,etc.
2 Drainage for tunnel, retaining wall,subway, and other underground projects
3 Drainage for hillside and bank slope, roof garden and other greening places.
4 Drainage for tall dam of mines, ash dam of fire, rubbish burying field, etc.
