Three-Dimensional Drainage Geonet With Complete Filtration And Protection
Product Introduction
Three-dimensional composite drainage network is a new type of drainage geotechnical material, which is composed of a three-dimensional geotechnical mesh core with needle-punched perforated non-woven geotechnical fabric adhered to both sides. The structure of this material consists of a thick vertical rib and one diagonal rib at the top and bottom.
Product Application
Darinage for the landfill, roadbed and road surface, railway, tunnel, underground structure, back of retaining wall, garden and playground, etc.
Product Property
The main function of the three-dimensional composite drainage network is drainage, while it can also play the role of isolation and base reinforcement. Throughout the entire process of use, it can withstand high compressive loads and maintain a considerable thickness, providing good water permeability. In addition, it can also provide complete "filtration-drainage-protection" functions.
The main uses of three-dimensional composite drainage networks include drainage in landfills, roadbeds, and tunnel interiors. It can also be used for drainage projects such as railways, highways, tunnels, municipal engineering, reservoirs, and slope protection, and has achieved remarkable results.
In summary, three-dimensional composite drainage networks are high-performance drainage materials widely used in various fields. If you need more information or have purchasing needs, you can contact Shandong geotechnical material manufacturers for consultation.
