Abstract: With the increase of operation time, underwater structure of PSPS would inevitably occur large or small defects, especially in vertical joints and perimetric joints, which often cause leakage. This paper explains the underwater treatment of leakage in a pumped storage power station. For various degrees of leakage, a variety of underwater flexible treatment technologies are adopted, which have achieved good results.

Key words: pumped storage power station, structural joint, leakage, flexible underwater treatment technology

摘要： 随着电站运营时间的增加，水下结构不可避免会出现或大或小的缺陷，特别是面板与面板之间、面板与趾板等交界处的结构缝，发生缺陷造成漏水的现象较为常见。笔者详细阐述了某抽水蓄能电站渗漏的水下处理技术，针对不同程度的漏水情况，采用了不同水下柔性处理技术，取得了良好的效果。
