Composite drainage
network( also
known as three-dimensional geotechnical drainage board, tunnel
discharge water board, discharge water board ) by the
three-dimensional structure of plastic mesh double-sided adhesive
permeable soil geotextile component, it can replace the traditional
sand and gravel, mainly used for landfill, roadbed and the inner
wall of the tunnel drainage.
In railway, highway and
other transportation infrastructure, engineering safety and the
service life and the drainage system has a close relationship which
can share, geotechnical synthetic material is an important part of
the drainage system.
Three dimensional composite drainage
network is a new type of geosynthetics. Structure is a
three-dimensional network geotextile core, both sides stuck with
acupuncture perforated nonwoven geotextile. Three-dimensional
network geotextile core includes a thick vertical ribs, as well as
the top and bottom of a slanting ribs. Can rapidly discharge path
of groundwater, oneself have a pore system, can be in high load
blocking the capillary water. At the same time, it can also play a
role in isolation and foundation reinforcement. A new type of
geosynthetics.
