泰安抽水蓄能电站上库右岸面板水下检查及处理效果分析

Underwater inspection and treatment analysis on concrete face of right bank of upper reservoir at Tai'an pumped-storage power station

泰安抽水蓄能电站上库右岸面板渗漏量呈增大趋势,并与进/出水口附近的面板垫层渗压水头正相关。水下检查发现进/出水口区域面板及结构缝破损,处理后渗漏量减小,运行一段时间后,渗漏量恢复处理前量值,处理未根治渗水问题,建议重新进行处理。

There was a growing trend of seepage at right bank concrete face of Tai＇an pumped-storagepower station, which was positively correlated with the water head on the concrete face cushion zone.Damage was found at concrete face and the structure joints of water inlet/outlet during the underwater in-spection. The seepage dropped after treatment, but returned to the value before over time. The treatmentfailed to solve the problem. We strongly recommend taking further action.
