Geotextile Filter
1. Geoscreen is usually made of polymer material, which has good water permeability and durability. Its structural design allows water to pass through quickly, while solid waste is intercepted on the screen, thus realizing effective filtration.
2. Geoscreen is mainly used for filtration and drainage of waste. It can effectively separate the water in the garbage from the solid waste to ensure that the water inside the landfill can be smoothly discharged, thus preventing the instability of the landfill and environmental pollution caused by the accumulation of water.
Geosynthetics filter mesh adopts polypropylene polyethylene polymer woven into a mesh permeable material is mainly used for landfill sublayer water filtration, the implementation of the standard: CJ/T 437-2013, to 200g per square meter, 300g dosage is predominant. If the design index model is expressed as: GF2-45-10-200 indicates that the collection of leachate with the geotechnical filter mesh, longitudinal tensile strength of 45KN / m, the open rate of 10%, the weight of 200g per square meter.
The use of geotechnical filter mesh is mainly used in two aspects, on the one hand, used for groundwater, garbage sealing surface layer of excess water collection, on the other hand, used for the garbage bottom layer of the collection of leachate use. In the specific procurement process must be clear in what position, in the landfill project will also be used in the geotechnical drainage network, known as three-dimensional composite drainage network, geotechnical filter mesh laid in the bottom or top layer of the geotechnical drainage network for the landfill slope seepage use, which is a completely different product.
