Three-dimensional composite drainage network
First, the three-dimensional composite drainage network profile:
Three-dimensional composite drainage network is a new type of geosynthetics. Composition structure is a three-dimensional geonet core, both sides stick acupuncture perforated nonwoven geotextile. Three-dimensional geonet core comprises a thick vertical ribs, as well as the top and bottom of the one inclined rib. Can be quickly discharged groundwater road itself has a pore maintenance system, can block the capillary water under high loads. At the same time, it can also play the role of isolation and foundation reinforcement.
Three-dimensional composite drainage network is made of a unique three-dimensional network geotextile geotextile double-sided adhesive. Combination of geotextiles (filtration effect) and geonet (drainage and protection) offers a complete "filtration - drainage - protection" effect.
Three-dimensional composite drainage network core network unique three-dimensional structure, the whole process that can withstand higher compressive load, and can keep a considerable thickness, providing a good hydraulic conductivity.
Second, the three-dimensional composite drainage network applications:
Landfill drainage; highway roadbed and road drainage; railway drainage; drainage tunnel; underground drainage structures; retaining wall rear drainage; garden and playground drainage.
