大盈江水电站蜗壳吊装施工技术研究

The Volute Lifting Construction Technology of Yingjiang Hydropower Station

在水电站施工当中,特别是在前期机电埋件施工时,厂房桥机没有形成,土建施工为节约投入成本,不愿过多和过早投入起吊设备,甚至不投入起吊设备,钢筋预制件采用农民工扛到仓号,混凝土入仓利用地形高差采用溜槽入仓,造成机电埋件运输就位困难,大吨位埋件无法施工,被迫修改施工措施。

In the construction of hydropower station, especially in the early embedded parts construction, building bridge machine was not formed. In order to save costs, they are not willing to input excessive and premature lifting equipment in civil construction, even do not input, ask the migrant workers to lift the reinforced precast to the warehouse number, use the concrete chute warehousing according to the topographic height difference, so the electrical embedded parts transport is difficult to emplace, large-tonnage embedded parts cannot be constructed, so we must modify theconstruction measures.
