摘要
金沙江向家坝水电站左岸大坝混凝土全面浇筑时间比原计划滞后了5个月。为此,采取了对不良地质体改用碾压混凝土回填,导流底孔顶板采用钢衬封顶,增大大坝浇筑高升层,调整施工设备布置等快速施工方法,从而保质保量地实现了主河床按期截流。
The placement of left bank dam concrete of Xiangjiaba Hydropower Station is delayed about 5 months.In order to meet the requirement of construction schedule,the river closure schedule is achieved on time after backfilling the bad geological restructure with RCC,sealing the diversion bottom outlet roof with steel liner,increasing the placement layer height of dam and adjusting the layout of construction equipment.
