摘要
沙沱水电站纵向混凝土围堰施工方案根据坝址区的实际地质地形条件、下游彭水水电站蓄水回水影响、乌江汛期洪水影响以及工期要求等因素的变化不断进行调整、优化,将水下混凝土施工由导管法施工调整为导管法施工为辅、进占挤压法施工为主,加快了混凝土施工进度,纵向混凝土围堰提前40 d达到防洪度汛高程。根据施工现场实际情况的变化不断调整、优化施工方案是顺利完成水利水电工程施工的关键。
The construction scheme optimization of Shatuo hydropower station's longitudinal cofferdam was determined through successive adjustment,optimization according to practical geological condition,backwater influence of downstream Pengshui hydropower station,flood influence of Wujiang river in rainy season etc.factors.The pre-determined tremie method for underwater concrete construction was changed by advancing and pressing method assisted by tremie method and the concrete construction was accelerated and the longitudinal concrete cofferdam was constructed to flood control elevation 40 days ahead of time.Adjusting and optimizing construction scheme successively according to practical condition is the key to complete construction of water conservancy and hydropower project.
