Plastic drainage Net

3-D composite drainage net is a new kind of drainage geomaterial, using high density polyethylene HDPE as raw material, it is produced by special extrusion technology. It is a 3-layer structure. The reinforcing strip in the middle has a large rigidity, the vertically arranged reinforcing strip allows the water to be drained in direct line pass, the reinforcing strip on both sides is crisscross arranged, so as to increase the stability of the drainage net. The combination of 3-D drainage net and geotextile enables this product to have the functioning of back-filtration, water drainage and protection, it is the most popular drainage geomaterial at present. 3-D composite drainage net has been used worldwide for the projects of rubbish dump water drainage, road base water drainage, road surface water drainage, railway water drainage, tunnel water drainage, underground structure water drainage, back of retaining wall water drainage, garden water drainage as well as sports field water drainage. Features of 3-D composite drainage net: high ability of water drainage (equivalent to 1 meter deep stone water drainage ability) can withstand high pressure loading stress for long period (can withstand 3000Kpa compressed loading stress) high tensile strength minimize the possibility of geotextile coming into the net core, thus to ensure long term hydraulic conductivity. erosion resistant, PH resistant, long life time convenient for construction, time-saving and low cost of engineering ItemDLF800/2DLF1000/2DLF1300/2DLF1600/2Remarktensile strength KN/M14182628compressed strength kpahigher than 1500higher than 2000higher 2200higher than 2500elongation %60606060hydraulitic conductivity 1/m/s0.70.750.80.9thickness Mm5.56.37.58weight g/m21200140017002000width M1.25,21.25,21.25,21.25,2Length M30,5030,5030,5030,50Remark: 1.
