摘要
某水利枢纽工程对溢洪道设计及施工情况、堰体裂缝渗水情况进行了调查,综合分析得出溢洪道控制段堰体主要渗水来源;针对渗水原因,对堰体结构缝、堰头、边墩与堰面混凝土间施工缝等部位采用相应的灌浆堵水处理措施,经处理后渗水明显减少,取得了良好的治理效果。
A water conservancy hub project conducts an investigation on the design and construction of the spillway,as well as the seepage conditions of cracks in the weir body.Through comprehensive analysis,the main sources of seepage in the control section of the spillway are identified.Based on the causes of seepage,corresponding grouting and water blocking measures are adopted for the structural joints of the weir body,the weir head and the construction joints between the side piers and the concrete of the weir surface.After treatment,the seepage is significantly reduced,achieving good control effects.
