Versatile Drainage Geonet For Reinforcement And Drainage In Landfill And Road Projects
Product Introduction
Three-dimensional composite drainage network is a new type of drainage geotechnical material that is widely used in landfill sites, roads, tunnels and other engineering projects. Here is a detailed introduction to the three-dimensional composite drainage network.Three-dimensional composite drainage network is usually composed of a three-dimensional geotechnical network with a stereo structure plastic mesh double-sided adhesive permeable geotechnical fabric. The middle three-dimensional geotechnical network is made of high-density polyethylene (HDPE) as raw material, adding carbon black, anti-ultraviolet, antioxidant agent, and then extruded to form a three-dimensional structure with intersecting ribs. This structure has extremely high rigidity and good drainage performance.
The main functions of the three-dimensional composite drainage network are drainage and reinforcement. It can withstand high pressure loads and quickly drain water; it is corrosion-resistant, acid and alkali resistant, and also plays a role in isolation and foundation reinforcement. In landfills, it can be used for groundwater diversion layers, leakage detection layers, leachate collection and diversion layers, gas collection and diversion layers at the end of closure, and surface water collection and diversion layers at the end of closure.
Product Application
Darinage for the landfill, roadbed and road surface, railway, tunnel, underground structure, back of retaining wall, garden and playground, etc.
