Description

Technical Field

[0001] The utility model relates to the technical field of anti-seepage of garbage landfills in environmental engineering, in particular to a flexible anti-seepage curtain for garbage landfills. Background Art

[0002] Domestic urban domestic waste contains a high content of kitchen waste components, which will produce a large amount of leachate after degradation. In order to prevent the leachate produced by waste degradation from polluting soil and groundwater resources, and thus affecting the ecological environment and human health, landfills need to take effective anti-seepage measures. At present, in valley-type landfills, the common vertical anti-seepage technology is to use concrete-like rigid materials to construct an anti-seepage layer, but these materials have certain limitations. For example, rigid materials are prone to cracks when geological conditions are complex or when the ground subsides, resulting in a decrease in anti-seepage effect; rigid materials are more expensive and difficult to construct; in addition, the anti-seepage layer constructed with rigid materials cannot effectively discharge biogas, and a gas collection and drainage system needs to be laid.

[0003] In view of the shortcomings of the prior art, the utility model proposes a flexible anti-seepage curtain for landfills. The flexible anti-seepage curtain is made of flexible materials with high elasticity, chemical corrosion resistance, and environmental aging resistance. It can effectively adapt to geological changes and reduce the occurrence of cracks caused by ground subsidence or geological displacement. At the same time, the construction of flexible materials is simple and the cost is relatively low, which is more suitable for large-scale landfill anti-seepage projects. In addition, the design of the flexible anti-seepage curtain also takes into account the synergy with other structures of the landfill, such as drainage systems, gas collection systems, etc., to achieve more efficient leachate management and environmental risk control. The use of this flexible anti-seepage curtain can not only effectively prevent the leakage of harmful substances, but also improve the overall operating efficiency and environmental friendliness of the landfill.
