摘要
采取在无水状态下进行封堵的施工方法,封堵渗漏水效果较好,但同时会影响到水利水电工程发电、灌溉、航运、养殖等效益,带来巨大的经济损失。以磨子潭水库放水底涵竖井井壁的渗漏水为背景,针对高水头压力下水工建筑物的渗漏水封堵方法进行研究,制订与之相对应的封堵方案,并付诸实施,成功封堵了渗漏水,有效解决了高水头压力下的渗漏水封堵难题,经济和社会效益显著。
The results of water sealing construction in a state free from water are comparatively better,meanwhile,the economic benefits of water conservancy and hydro-power projects in the aspects of power generation,irrigation, navigation, cultivation and so on, would be greatly affected. This paper exemplifies the water leakage conditions in the walls of vertical shafts of the discharge bottom culvert in Mozitan reservoir,focuses on the study on the water sealing technology for the hydraulic structures under high waterhead pressure and figures out the corresponding practicable sealing programs to solve the existing water leakage successfully,in which the difficulties of water sealing under high waterhead pressure are not only solved effectively but also remarkable economic and social benefits are produced.
