溪洛渡水电站右岸导流洞混凝土衬砌施工技术

Concrete Lining Technology of Extra-large Diversion Tunnel on the Right Bank of Xiluodu Hydropower Station

溪洛渡水电站右岸导流洞工程为特大型洞室群。在导流洞村砌混凝土施工过程中,克服了泵送混凝土施工不易组织,特大型钢模台车不易调校、混凝土过流面质量要求高等多重困难,认真制定措施和预案,开展技术攻关,摸索出了一套特大型洞室衬砌混凝土施工经验,为工程的顺利实施提供了保障。

The right-bank diversion tunnel of Xiluodu Hydropower Station is an extra-large cavern group. In the concrete lining construction of diversion tunnel, we overcame many difficulties in the aspects of pumping concrete, the adjustment of oversize steel-frame trolley, the high quality requirement of concrete overflow-surface. We seriously formulated many measures and emergency alternatives and developed the technical researches so that we gained a series of concrete lining construction experience of extra-large tunnel ,which provides the guarantee for the smooth completion of the project.
