Full-reservoir-basin integrated anti-seepage system for pumped storage power station and construction method
The invention relates to the technical field of hydropower and hydraulic engineering, and provides a full-reservoir-basin integrated anti-seepage system for a pumped storage power station and a construction method of the full-reservoir-basin integrated anti-seepage system. The composite impermeable layer completely covers the inner wall of the upper reservoir basin, and the composite impermeable layer comprises inner geotechnical cloth, a geomembrane and outer geotechnical cloth which are sequentially stacked from inside to outside; the transition connecting layer comprises a lower cushion layer, a geotechnical mat and an anchoring strip, the anchoring strip is fixedly embedded in the lower cushion layer and/or the inner wall of the upper reservoir basin, and the anchoring strip is connected with the composite impermeable layer in a welded mode; the drainage system is used for avoiding the local swelling phenomenon of the composite impermeable layer; a self-adaptive groove is formed in the transition connection position of the reservoir bank slope face and the reservoir bottom. And/or a self-adaptive groove is formed in the transition joint of the dam slope surface and the reservoir bottom; integrated seepage prevention of the reservoir basin, the reservoir bottom and the dam slope can be achieved, and the method has the advantages of being high in construction speed, good in seepage prevention effect and low in construction cost.
本发明涉及水电水利工程技术领域，提供一种用于抽水蓄能电站的全库盆一体化防渗系统及施工方法，包括：上库盆内壁；复合防渗层，复合防渗层全面覆盖于上库盆内壁，复合防渗层包括由内朝外依次叠设的内土工布、土工膜以及外土工布；过渡连接层，过渡连接层包括下垫层、土工席垫以及锚固条带，锚固条带固定嵌设于下垫层和/或上库盆内壁，并且锚固条带和复合防渗层焊接相连；排水系统，避免复合防渗层出现局部鼓包现象；其中，所述库岸斜坡面与库底的过渡衔接处设有自适应凹槽；和/或，坝坡面与库底的过渡衔接处设有自适应凹槽；本发明能够实现库盆、库底及坝坡一体化防渗，具有施工速度快、防渗效果好、工程造价低的特点。
