Problems solved by technology

[0003] The anti-seepage system of the storage and disposal site of the second type of general industrial solid waste generally adopts a single-layer HDPE geomembrane as the main anti-seepage material. As the weak point of anti-seepage, the connection is very prone to leachate leakage accidents
[0017] The overlapping structure of the existing anti-seepage system and the drainage shaft cannot completely avoid the possibility of tearing of the anti-seepage structure due to uneven force or excessive force, which may cause leakage of anti-seepage leachate. Improvement of the overlapping structure between the seepage system and the drainage shaft

Abstract

The invention provides an anti-seepage system and drainage shaft lap structure for a second-type storage and disposal site. The structure comprises a drainage shaft. The drainage shaft comprises a shaft foundation and a shaft wall on one side of the shaft foundation. An HDPE connection lock is embedded in the shaft well foundation. The other side of the shaft foundation is provided with an anti-seepage system. The two sides of the anti-seepage system are correspondingly provided with a shaft sidewall anchoring trench and a reservoir area anchoring trench. The shaft sidewall anchoring trench isconnected with the shaft foundation. The structure eliminates the weak link of connection between the anti-seepage system and the drainage shaft, and ensures the safety and reliability of the anti-seepage system. By adopting the combined structure of the double-layer anti-seepage system, an auxiliary anti-seepage system and an anti-seepage protection system, the anti-seepage system and drainage shaft lap structure takes geomembrane as a main material, thereby promoting the reliability of the anti-seepage system in the reservoir area of the storage and disposal site of second-type general industrial solid waste, and also having a certain reference significance for the projects of domestic waste landfill and safe landfill disposal site of hazardous waste.

Description

technical field [0001] The invention relates to a second-type storage and disposal field anti-seepage system and a drainage shaft overlapping structure, which is suitable for the second-type storage and disposal field containing this type of structure, and can be extended to domestic garbage landfills and hazardous waste safety filling Landfill and other projects. Background technique [0002] In recent years, the output of the second type of industrial solid waste has been increasing, and the environmental problems brought about by it have become increasingly prominent. In particular, if the leachate produced after the harmful substances in the waste residue are soaked by rainwater is not effectively treated, it will cause great pollution to the surrounding environment and groundwater. At present, the national environmental protection authority has promulgated corresponding laws, regulations and regulations, requiring that the second type of industrial solid waste must be ...
