Application of geomembrane in landfill

The foundation of the composite lining structure at the bottom of the landfill, the groundwater diversion layer, the thickness should be greater than 30cm, the anti-seepage protective layer under the HDPE impermeable membrane, the clay thickness should be greater than or equal to 100cm, and the permeability coefficient should not be greater than 1.0 × 10-7cm / s , HDPE high quality plastic geonet, under-membrane protective layer, leachate diversion layer, the thickness should be greater than or equal to 30cm, geotextile layer, composite lining structure foundation of the slope in the reservoir area, groundwater diversion layer, the thickness should be greater than 30cm; Seepage protective layer, clay thickness should be greater than 75mm; permeability coefficient should not be greater than 1.0 × 10-7cm / s, HDPE geonet manufacturers, membrane protective layer, leachate diversion and buffer layer. Urban life landfills must be anti-seepage treatment, HDPE high quality HDPE geonet can play a good anti-seepage effect, to prevent pollution of groundwater and surface water, and also should prevent groundwater from entering the landfill. The artificial anti-seepage system shall meet the following requirements: the anti-seepage system of the synthetic lining shall adopt the composite lining anti-seepage system. The anti-seepage system located in the area with poor groundwater may also adopt the single-layer lining anti-seepage system. In areas with very high environmental requirements, a double-lined anti-seepage system is used at the bottom of the reservoir area.
