Warp knitted grill reinforcing composite geomembrane

A warp knitted grill reinforcing composite geomembrane consists of a geo-fabric layer, an ordinary geomembrane layer and a warp knitted grill layer, and the composite layers are arranged together through heat sealing or bonding. The utility model adopts composite layers and integrates functions of three materials, including warp knitted grills, geotextiles and ordinary geomembranes, as a whole, and overcomes the disadvantages of low geomembrane intensity, over-high elongation percentage, high probability of puncturing, high probability of tearing and the like in the ordinary geomembrane. The warp knitted grill reinforcing composite geomembrane has the characteristics of high tensile strength, low elongation percentage, even longitudinal deformation and lateral deformation and high tearingstrength, and has the advantages of high puncture resisting intensity, high waterproof and drainage capacity, large friction factor and small coefficient of inertia expansion. The warp knitted grill reinforcing composite geomembrane is widely used in projects involved in railroads, tunnels, subways, culverts, express ways, sports halls, dams, hydraulic architectures, coastal shoals, reclamations,environmental protections and the like, and can play good water resisting, seepage-proofing, strengthening, reinforcing as well as protecting effects.
