滴水崖水库属小(Ⅰ)类水库,除险加固前由于大坝渗漏严重,多年来一直空库运行。在除险加固工程中我们针对滴水崖水库所具有的特殊性,经过多个方案比选,最终选定了在上游坝坡内斜铺复合土工膜的方式进行防渗处理。水库除险加固工程完工至今,经过近3年的运行,实践证明了该种方式的防渗处理,不仅在施工中节约了投资,而且目前的防渗效果十分显著。
Di Shuiya reservoir is a small (Ⅰ) reservoir, due to the serious leakage of the dam before excavation, it has been empty for many years. In the project of reinforcement and reinforcement, we aimed at the particularity of Dachai Cliff Reservoir, and after several schemes comparison and selection, we finally chose the way of anti-seepage treatment by obliquely laying the composite geomembrane in the upstream dam slope. After the completion of the reservoir reinforcement project, after nearly 3 years of operation, this type of seepage prevention treatment has been proved, which not only saves investment in construction but also shows significant effect of anti-seepage.
