Advanced Three-Dimensional Composite Drainage Network For Reservoirs And Slope Protection
Product Introduction
Three-dimensional composite drainage network is composed of plastic mesh with three-dimensional structure and double-sided bonding of water permeable geotechnical fabric. This structure endows the three-dimensional composite drainage network with good drainage performance, and it can also replace the traditional sand and gravel layer to play a drainage role in landfills, roadbeds and tunnel inner walls.
Product Application
Three-dimensional composite drainage network is widely used in drainage projects such as railways, highways, tunnels, municipal engineering, reservoirs, and slope protection due to its unique properties. It not only enhances the safety and service life of the project but also effectively drains water, reducing maintenance costs.
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.
