Anti-seepage drainage and plugging system for pumped storage power station upper storage and construction method thereof
The invention relates to the field of anti-seepage treatment of hydropower stations, and particularly relates to an anti-seepage drainage and plugging system for a pumped storage power station upper storage and a construction method thereof. The drainage and plugging system comprises a tank body arranged in the area, with the water seepage amount smaller than 5L/d, of a dam body, the tank body isfilled with a plugging layer, and mortar layers are arranged on the upper surface of the tank body and the upper surface of the plugging layer. The drainage and plugging system further comprises an anti-seepage hole formed in the area, with the water seepage amount not smaller than 5L/d, of the dam body; the direction of the opening end of the anti-seepage hole is the downhill direction; a drainage pipe is arranged in the anti-seepage hole; an one-way check valve is arranged at the upper end of the part, extending out of the anti-seepage hole, of the drainage pipe; and a primer layer, an epoxymortar layer and a polyurea layer are sequentially arranged on the periphery of the outer side of the anti-seepage hole from bottom to top. The construction method comprises the steps of water seepage amount checking-plugging-drainage. The drainage and plugging system is ingenious in design and reasonable in structure, a plugging or drainage mode is adopted for seepage prevention in a reverse water pressure seepage area according to the water seepage amount, the anti-seepage effect is good, construction operation is convenient, and practicability is high.
本发明涉及水电站防渗处理领域，尤其涉及一种抽水蓄能电站上库防渗引排封堵系统及其施工方法，所述引排封堵系统包括坝体上在渗水量小于5L/d的区域设置的槽体，槽体内填充有封堵层，槽体和封堵层的上表面设置砂浆层；引排封堵系统还包括坝体上在渗水量不小于5L/d的区域设置有防渗孔，防渗孔的开口端的方向为顺坡方向，防渗孔内设置有排水管，排水管伸出防渗孔的部分上端设置有单向逆止阀，防渗孔外侧周围从下到上依次设置有底漆层、环氧砂浆层和聚脲层。该施工方法包括渗水量检查‑封堵‑引排步骤，该引排封堵系统设计巧妙，结构合理，在反向水压渗水区根据渗水量的大小采取封堵或引排方式进行防渗，防渗效果好，施工操作方便，实用性强。
