万家寨水利枢纽尾水河道左岸护坡加固改建

Reinforcement and reconstruction on left bank slope protection of tailrace channel of Wanjiazhai Water Conservancy Project

万家寨水利枢纽尾水河道左岸护坡受多年长时间、大流量泄洪冲刷影响,导致尾水河道左岸铅丝石笼护坡、浆砌石护坡等护坡结构出现不同程度的开裂、淘空、坍塌,为满足永久工程安全运行要求,对尾水河道左岸护坡进行必要的防护加固及改建处理,文中通过方案对比,确定加固处理方案为贴坡混凝土护坡形式,该方案的实施,保障了河道行洪安全。

The left bank slope protection of tailrace river of Wanjiazhai Water Conservancy Project is influenced by years of long time and large flow flood discharge,resulting in different degrees of cracking,scouring and collapse of the left bank slope protection structure of tailrace river,such as lead-wire gabion slope protection and slurry stone slope protection.In order to meet the requirements of the safe operation of the permanent project,necessary protection,reinforcement and reconstruction of the left bank slope protection of tailrace river are carried out.Through the comparison of the schemes,the reinforcement scheme is determined to be the form of slope concrete protection.The implementation of the scheme ensures the flood safety of the river.
