Landfill reservoir area anti-seepage system capable of protecting geomembrane and construction method thereof
The invention relates to the technical field of landfill facilities, and particularly relates to a landfill reservoir area anti-seepage system capable of protecting a geomembrane and a construction method thereof. The landfill reservoir area anti-seepage system comprises a reservoir bottom anti-seepage system and a side slope anti-seepage system; the reservoir bottom anti-seepage system comprises a compacted clay layer, a bentonite waterproof blanket, at least one layer of geomembrane, a rubble layer and a woven geotechnical filter screen which are vertically arranged from bottom to top; the side slope anti-seepage system comprises a compacted clay layer, a bentonite waterproof blanket, at least one layer of geomembrane, a rubble layer and a woven geotechnical filter screen which are obliquely arranged from bottom to top; and geotechnical cloth is laid on the upper layer of the geomembrane, and a high-tensile filter and discharge plate is laid on the upper layer of the geotechnical cloth. The landfill reservoir area anti-seepage system is simple in structure and convenient to construct, compared with a traditional landfill anti-seepage system, resources are saved, the reservoir capacity is increased, meanwhile, the geomembrane in the anti-seepage system can be effectively prevented from being damaged, and the service life is prolonged.
本发明涉及填埋设施技术领域，具体涉及一种可以保护土工膜的填埋场库区防渗系统及其施工方法，包括库底防渗系统和边坡防渗系统，所述库底防渗系统包括垂直的自下而上设置的压实粘土层、膨润土防水毯、至少一层土工膜、碎石层和有纺土工滤网；所述边坡防渗系统包括倾斜的自下而上设置的压实粘土层、膨润土防水毯、至少一层土工膜、碎石层和有纺土工滤网；所述土工膜的上层铺设土工布，所述土工布的上层铺设高抗拉滤排板；本发明结构简单，便于施工，与传统的填埋场防渗系统相比节约资源，增大库容，同时可以有效地避免防渗系统中的土工膜被破坏，延长了使用寿命。
