鉴于龚嘴水电站运行发电已30余年，在第三轮定期检查中，得知7号溢洪道左侧导墙被高速水流淘刷出长约13m、高约3m、最深处约3m的深坑，已经威胁到溢洪道及临近的6号冲砂底孔的安全运行，介绍了龚嘴大坝7号溢洪道左侧导墙水下冲蚀破坏部分采用水下不分散混凝土修补的工程实例。
鑒于龔嘴水電站運行髮電已30餘年，在第三輪定期檢查中，得知7號溢洪道左側導牆被高速水流淘刷齣長約13m、高約3m、最深處約3m的深坑，已經威脅到溢洪道及臨近的6號遲砂底孔的安全運行，介紹瞭龔嘴大壩7號溢洪道左側導牆水下遲蝕破壞部分採用水下不分散混凝土脩補的工程實例。
감우공취수전참운행발전이30여년，재제삼륜정기검사중，득지7호일홍도좌측도장피고속수류도쇄출장약13m、고약3m、최심처약3m적심갱，이경위협도일홍도급림근적6호충사저공적안전운행，개소료공취대패7호일홍도좌측도장수하충식파배부분채용수하불분산혼응토수보적공정실례。
As the Gongzui hydropower station has been operated more than 30 years, regular inspection and repairing is of great necessity .Results of the third round periodic inspection showed that the left-side guide wall of the No .7 spillway has been carved out a deep pit about 13 m in length, 3 m in height and 3 m in depth, which is of great threat to the safe operation of the spillway and the neighboring No .6 bottom outlet .This paper presents the subaqueous repairing work with underwater non-dispersed concrete for the eroded part of the left-side guide wall in the No .7 spillway in Gongzui hy-dropower station .
