Versatile Three-Dimensional Drainage Geonet for Civil and Environmental Projects
Product Introduction
Three-dimensional composite drainage network is a new type of geosynthetic material with unique structure. It consists of a three-dimensional geotechnical mesh core and two needle-punched perforated non-woven geotechnical fabrics pasted on both sides. The three-dimensional geotechnical mesh core includes a thick vertical rib, as well as one oblique rib at the top and bottom.
Product Application
It is mainly used for drainage projects in railways, highways, tunnels, municipal engineering, reservoirs, retaining slopes, etc., and has remarkable effects. It is widely used in underground water collection and drainage projects in civil, transportation, water conservancy, civil construction, mining, environmental protection and other construction projects. It is also used more in landfill sites, such as as the surface water diversion layer and gas diversion layer of the landfill site closure system, and can also be used as the main leachate collection and diversion layer (LCRS), which can discharge the leachate from the impervious membrane in time, making the water head less than the thickness of the geotechnical drainage material, reducing the leakage of the geomembrane caused by excessive water head; it can also play a role in garden and sports field drainage.
Product Property
The three-dimensional composite drainage net has high tensile strength and shear strength, can withstand long-term high pressure loads, and can maintain a considerable thickness, providing good water conductivity. In addition, it also has good corrosion resistance and acid and alkali resistance, and has a long service life.
