白云水电站混凝土面板堆石坝渗漏处理技术
Seepage treatment technology for RCC dam of Baiyun Hydropower Station
摘要
Abstract
The RCC dam of Baiyun Hydropower Station, with the largest height of 120m, reached a maximum seepage volume of 1240L/s with further rising before the reinforcement, thus it threatens the dam safety seriously. We introduce some new tech-nologies in the reinforcement, namely seepage detection by sonar in deep water, underwater lifting of closure gate, underwater blasting-demolition of rock plugging, also present some systematic RCC treatment technologies such as large scale renovation of concrete slab, slab crack treatment, hollow detection under slab and its grouting treatment, dense grouting for loose cushion lay-er, renovation of water-sealing. Until now, the seepage volume of the dam has lowered to 50L/s after systematic reinforcement, showing perfective effect, so the seepage location and treatment technologies could provide valuable references to other RCC dams.关键词
