Drainage and Filtration Performance Three-Dimensional Composite Drainage Network for Landfill Roadbed and Tunnel Wall
Drainage and Filtration Performance Three-Dimensional Composite Drainage Network for Landfill Roadbed and Tunnel Wall
Product Introduction
Three-dimensional composite drainage network is a new type of geosynthetic material, mainly composed of three-dimensional plastic mesh and waterproof geotechnical fabric pasted on both sides. This material can not only replace the traditional sand and gravel layer but also has extensive applications in various fields, especially in engineering projects requiring efficient drainage.
Product Property
-
Filtering: The geotechnical fabric provides a filtering function, preventing soil particles from being carried away by the water flow.
-
Drainage Function: The three-dimensional mesh core effectively drains groundwater, reducing groundwater pressure.
-
Protective Function: Protect the soil and buildings from infiltration deformation by means of isolation and foundation reinforcement.
Product Application
Three-dimensional composite drainage network is widely used in underground drainage projects in civil engineering, transportation, water conservancy, civil construction and mining, environmental protection and other fields because of its unique drainage and filtration performance. Especially in the application of landfill, roadbed and tunnel wall, it can effectively collect and discharge water seepage in the soil, reduce groundwater pressure, and protect the safety of soil and buildings.
