苏阿皮蒂水利枢纽大坝泄流底孔坝段混凝土入仓方式研究

Study on Concrete Placing Methods in Flood Discharge Bottom Outlet Dam Section of Souapiti Hydro Project

苏阿皮蒂水利枢纽项目大坝是以碾压混凝土为主的重力坝,根据施工条件的变化,泄流底孔坝段在不同阶段灵活采取了多种混凝土入仓方式,避免了该坝段结构体型复杂、结构布置位置独特等因素造成的影响,为满足施工进度要求创造了条件。介绍了4个不同阶段混凝土入仓方式,可供同行参考。

The dam of Souapiti Hydro Project is a gravity dam mainly composed of roller compacted concrete.In the concrete construction of dam section of flood discharge bottom outlet,various concrete placing methods are flexibly adopted according to the changes of construction conditions,which avoid the influence of complex body shape and unique structure on concrete placing and guarantee construction progress.The concrete placing methods at four different construction stages are introduced herein.
