响水涧抽水蓄能电站下水库大型土方工程施工技术

Construction Technology for Large Earthworks of Lower Reservoir in Xiangshuijian Pumped Storage Power Station

安徽响水涧抽水蓄能电站下水库土方开挖工程量约916万m3,其中Q4土656万m3,通过"外防、内排、分区、修路、防护、跟进"施工技术策略,克服了Q4土开挖和弃渣机械设备沉陷、石渣料源紧缺道路修筑难、天气影响施工组织难、有效施工天数有限、施工强度大等难题,按期完成了库盆开挖、围堤填筑施工任务。

Engineering quantities for ground excavation of lower reservoir in Xiangshuijian Pumped Storage Power Station in Anhui is about 9.16 million cubic meters,in which the engineering quantities of Q4 ground is about 6.56 million cubic meters.By adopting a series of construction technologies of outer of prevention,inner of drainage,etc.some problems of subsidence of machine for excavation of Q4 soil,difficult building road because of shortage materials,difficult construction organization because of weather and short construction period are solved to done the construction of ground excavation and fulfill of dyke on schedule.
