Anti-seepage system of landfill for extending penetration time of leachate and manufacturing method thereof
Disclosed is an anti-seepage system of a landfill for extending a penetration time of a leachate, comprising, layered from top to bottom in sequence, a leachate collection and drainage layer (1), a first HDPE geomembrane anti-seepage layer (2), a clay layer (5) and a groundwater collection and drainage layer (6). The clay layer (5) comprises a lower clay layer (51), a middle clay layer (52) and an upper clay layer (53) disposed in sequence. The middle clay layer (5) is filled with a medium-fine sand layer (7) therein. The medium-fine sand layer (7) is formed of sand grains having a grain size of 0.1-0.5 mm, a moisture content of ≤ 3%, and a saturated permeability coefficient thereof is from 1 × 10
