High Strength Drainage Geonet with Excellent Drainage Performance
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.
Structural Features
The structure of the three-dimensional composite drainage network is composed of a three-dimensional plastic mesh with permeable geotechnical fabric adhered to both sides. This structure gives it several distinct characteristics:
High Strength: The three-dimensional composite drainage network has high tensile strength and can withstand high pressure loads, even capable of supporting a compression load of about 3000Ka.
Good drainage performance: It has excellent drainage capabilities, equivalent to the drainage effect of a one-meter thick layer of gravel.
Durability: The material is corrosion-resistant, acid-base resistant, and has a long service life, making it suitable for various harsh environments.
Stability: Reduced the likelihood of geotechnical fabric embedding into the mesh core, maintaining long-term stable water permeability.
Easy Construction: Convenient construction can shorten the cycle and reduce costs.
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.
In summary, three-dimensional composite drainage networks are high-performance geosynthetic materials. Their application not only improves the safety and service life of engineering projects but also simplifies construction processes and reduces costs. With the advancement of technology and the development of new materials, three-dimensional composite drainage networks will play an even more important role in future engineering construction.
