河南省宿鸭湖水库大坝渗水异常，下游出现沼泽化，长度绵延几公里，积水宽度30～50m，积水量随库水位升降而增减明显。经勘探，存在中等—强透水砂层。经方案比选，采用深层水泥土搅拌桩防渗墙进行防渗处理，施工中严格按照施工方案控制施工质量。完成后与历史同期相同水位比较，防渗效果明显。
河南省宿鴨湖水庫大壩滲水異常，下遊齣現沼澤化，長度綿延幾公裏，積水寬度30～50m，積水量隨庫水位升降而增減明顯。經勘探，存在中等—彊透水砂層。經方案比選，採用深層水泥土攪拌樁防滲牆進行防滲處理，施工中嚴格按照施工方案控製施工質量。完成後與歷史同期相同水位比較，防滲效果明顯。

Henan Suya Lake Reservoir dam has abnormal water seepage.Paludification is occured in the downstream area, and the length extends for several kilometers.Water-logging width is 30 ~50m.Accumulated water is significantly increased or decreased with reservoir water level.Medium-strong permeable sand layer is available according to exploration. Seepage prevention treatment is implemented with deep cement-soil mixing pile cut-off wall through scheme comparison. Construction quality is controlled in strict accordance with construction plan in construction.It is compared with the same water level at the same period after the project completion,and seepage control effect is obvious.
