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.
