Excellent Drainage Capacity Three-dimensional Composite Drainage
Network for Traffic Infrastructure
Product Introduction
Three-dimensional composite drainage network is a new type of
geosynthetic material, mainly consisting of a three-dimensional
plastic mesh with both sides bonded with water permeable
geotechnical fabric. This material not only can replace the
traditional sand and gravel layers but also has extensive
applications in various fields, including landfills, roadbeds,
tunnel interiors, etc.
Product Application
Traffic Infrastructure
In transportation infrastructures such as railways and highways,
the safety and lifespan of three-dimensional composite drainage
networks are closely related to their drainage systems. They
effectively drain groundwater from beneath roads, reducing
structural damage caused by waterlogging.
Environmental Engineering
Landfill Drainage: Effectively manage leachate to protect the surrounding
environment.
Tunnel Drainage: Prevents groundwater accumulation, ensuring construction safety
and the normal use of tunnels.
Municipal Engineering
In urban infrastructure construction, three-dimensional composite
drainage networks are used for road base and surface drainage,
which helps to improve the trafficability and service life of
roads.
Product Property
The main characteristics of the three-dimensional composite
drainage network include excellent drainage capacity, high tensile
strength, and the ability to maintain stable drainage performance
under high loads. In addition, the material also has good corrosion
resistance and acid-base resistance, long service life, convenient
construction, and low cost.
