预制梁在河床式水电站坝顶施工中的应用

Application of Precast Beams in Dam Crest Construction of Riverbed Hydropower Station

旬阳水电站坝顶梁因多种原因影响无法形成运输通道而造成原施工计划无法实施。项目部经研究后针对左五孔泄洪冲沙闸坝顶门机及交通梁采用预制梁吊装技术提前安装就位,解决了坝顶施工通道问题,取得了较好的效果。阐述了对预制梁在河床式水电站坝顶施工中的应用进行的研究。

The dam crest beams of Xunyang Hydropower Station cannot form a transportation channel due to many reasons,making the original construction plan unable to be implemented.After research,the project department adopted precast beam hoisting technology to install in advance,which achieved good results solved the problem of dam roof construction channel.This paper describes the research on the application of precast beams in dam crest construction of riverbed hydropower stations.
