Geomembrane liner for anti-seepage of large landfills
Geomembrane liner for anti-seepage of large landfills
The spatial hierarchy of various materials in the landfill anti-seepage system includes the base layer, anti-seepage layer, protective layer, leachate drainage system and groundwater drainage system.
The garbage dump covering project should be completed before the rainy season. If the project is large and needs to be constructed across the rainy season, temporary covering measures should be taken for the unfinished part to reduce the penetration of rainwater into the garbage dump.
Each layer of the system in the landfill should have the functions of exhaust, anti-seepage, drainage, and greening. From the bottom layer, it is the garbage pile, drainage layer, anti-seepage layer, drainage layer, and greening soil layer.
The geomembrane can be 1.5mm, and protective layers should be set up on the top and bottom to prevent the geomembrane from being damaged. Double rough geomembrane should be used on the slope, and geomembrane anchor trenches should be set on the slope.
