摘 要: 双塔水库除险加固工程1号副坝混凝土防渗墙施工,是此次除险加固工程的关键分部工程。在工程实施前,坝体主河道段存在三个渗漏点,在防渗墙施工过程中,严把工程程序验收关,尤其在坝体最大渗流点的老输水洞部位防渗墙施工中,成功处置了塌孔事故,为同类防渗墙工程施工提供了参考。 Construction of No. 1 auxiliary dam concrete cutoff wall in Shuangta Reservoir Reinforcement Project is a key sub-project of the reinforcement project. The dam main river section has three leakage points before project implementation.Project procedure acceptance should be strictly controlled during cutoff wall construction process,especially in the cutoff wall construction of the old water conveying tunnel with the largest leakage point of the dam. The hole collapse accident is handled successfully,thereby providing reference for similar cutoff wall engineering construction.
