响水潭水库输水管竖井堵漏与加固实践

Caulking and reinforcement between water pipeline and vertical shaft in Xiangshuitan Reservior

响水潭水库输水管竖井圆筒底部与问室连接处下游侧面出现长达11．5m，宽约2～20mm的裂缝，应用了化灌与外粘钢板加固技术对其进行堵漏与加固。应用4年来，效果良好。

Between the bottom of the vertical shaft and the connected part of sluice gate chamber,there is a crack 11. sin in length and 2-20mm in width. We use chemical grouting to caulk it and reinforce structure by adhesion technology of steel plate. The methods get good results,and these buildings have been used for four years.
