Comprehensive drainage and seepage system of composite drainage and seepage wall of solid waste landfill

The invention discloses a composite drainage and seepage wall comprehensive drainage and seepage system of a solid waste landfill. A drainage and seepage wall composite drainage and seepage body comprises a coarse sand protection layer (6), a melon seed piece permeable layer (4) and a coarse sand protection layer (6) from left to right, and vertical non-woven geotechnical cloth (5-1) is externally attached to the two sides of the melon seed piece permeable layer (4) respectively; solid waste layers (8) for landfill of the II-type solid waste landfill are arranged on the two sides of the composite drainage and seepage body of the drainage and seepage wall; and a broken brick covering layer (7) is laid at the upper part of the composite seepage drainage body of the seepage drainage wall at the heightening stage. The seepage drainage wall composite seepage drainage body is arranged along with the running stage of the landfill, seepage drainage of the landfill is completed by increasing the seepage fracture surfa
