摘要
沙河抽水蓄能电站运行已五年。在2005年检查时发现大坝混凝土面板出现了若干裂缝,经过认真分析,确定采用灌浆和SR止水材料的处理措施,于2006年进行了处理。2007年4月对面板进行了复查,处理效果良好,满足裂缝封闭和防止裂缝继续开展的要求。
After 5-year operation of Shahe Pumped-storage Power Station, we found several cracks on the concrete facing slab in the overhaul in 2005. By careful analysis, we determined to adopt the treatment by grouting and laying on SR sealant, which was done in 2006. We re-checked the facing slab in April 2007 and found out its treatment result is good and it met the requirements of closing the cracks and preventing the crack development again.
