[0002] With the increasing requirements for the ecological environment, more and more solid waste projects at home and abroad, such as non-ferrous tailings, non-ferrous smelting waste, phosphogypsum, manganese slag, red mud, etc., are required to carry out different levels of horizontal anti-seepage design for the entire reservoir area according to their solid waste categories during the new construction or renovation and expansion process.

[0003] Chinese patent application No. 202321853507.2 discloses a groundwater seepage collection structure for a tailings pond. The structure arranges a foundation layer under the impermeable membrane and a seepage collection well on the upper side of the impermeable membrane. The seepage water under the membrane is collected into the well through the water collection holes and then drained out of the tailings pond through a drainage pipe. This reduces the investment in arranging a groundwater drainage layer in the entire reservoir area. At the same time, it can more effectively drain the groundwater accumulation area, achieve the effect of drainage under the membrane, and reduce the damage to the impermeable membrane caused by the water pressure under the membrane.

[0004] In the above-mentioned public patent, the wire mesh is fixedly installed inside the water collection hole for filtering groundwater. The mesh holes of the wire mesh are easily blocked after long-term use, which will affect the normal water seepage use of the water collection hole. The cover plate and the well body are separated structures, and the connection is not tight enough, resulting in poor use effect. Utility Model Content
