Three-dimensional geotechnical drainage network to high-density polyethylene as raw material, through a special extrusion head ribs, three ribs arranged at a certain distance and angle of the drainage guide groove formed three-dimensional structure. Intermediate ribs having a greater rigidity, a rectangular drain passage. Drainage network composed of three ribs have a high tensile strength and compressive strength of vertical and horizontal drainage guide groove formed between three ribs not easily deformed at higher loads, it is possible to prevent the geotextile geotextile embedded core network to ensure smooth drainage . Three-dimensional geotechnical drainage network based on the use of high strength and high conductivity row type. Three-dimensional geotextile composite drainage network can be used to: 1, groundwater discharge guide layer 2, layer 3, leak detection, leachate collection discharge guide layer 4, closure gas collection discharge guide layer 5, sealing the site to collect surface water discharge guide 6, in the garbage Underground landfill drainage 7, the role of the characteristics of landfill leachate drainage layer and leak detection layer drainage network: the laying of the foundation and between the substrate can be shortened foundation drainage pathways. ******************************************* Company: Shandong Xiang New Material Ltd.
