修山水电站工程采用分期导流方式施工,经多方案技术经济比较,导流方式选定一期先围右岸电站厂房和13.5孔溢流坝做枯期土石围堰,第一枯水期末拆除一期枯期土石围堰,在厂房全年小基坑内继续施工厂房。二期围余下的溢流坝及船闸,为不过水围堰,厂房第一台机发电利用溢流坝挡水发电,船闸完工前利用闸孔通航。工程实施结果表明该导流方案基本符合工程的具体情况。 Xiushan hydropower station construction by staging diversion approach, the technical and economic comparison of the multi-program, the diversion mode selected a first-around right-bank power plant and 13.5-hole overflow dam dry season rock cofferdam, the first dry-period demolition of a Dry earth cofferdam, small plant in the plant throughout the year to continue construction of the plant. The remaining two overflow dams and locks, but cofferdam cofferdam, the first machine generating plant using spillway retaining water power generation, gate lock before the completion of navigation. The result of the project implementation shows that the diversion scheme basically conforms to the specific conditions of the project.
