三峡电源电站主厂房蜗壳层混凝土施工技术

Construction Technology of Concrete for Snail Shell Layer of Main Plant Building of Sanxia Electric Power Station

蜗壳层混凝土被称为电站厂房混凝土的“心脏”,是最关键和最难浇筑的部位。三峡电源电站厂房采用铺设弹性垫层,蜗壳座环阴角区采用预埋泵管在浇筑同时回填砂浆的方法,不但施工质量非常好,还可免去二次回填灌浆。从而减少了施工工序,加快了施工进度。

The concrete for snail shell layer is called＂ heart＇ of concrete used in the plant building of the power station , also it is the Most essential and difficult to pour part. In the construction of the plant building of Sanxia Electric Power Station , building the elastic cushion layer is applied , and in advance , embedding pump pipes , at the same time of pouring , baekfillingmortar is applied . In this way , the construction quality is very good , also dispensing with backfilling mortar once more . Therefore , the construction working procedure is lessoned , and the construction tempo is quick- ened
