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.
