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.
Function and Purpose
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.
