堆石重力坝自密实混凝土砌石施工

Self-compacting concrete masonry construction of rockfill gravity dam

为解决堆石重力坝空隙填充施工效率低的问题,文中提出了自密实混凝土砌石的施工方法,即先向仓面中放入大粒径块石,从而形成一个具有大孔隙的堆石仓面,再浇筑自密实混凝土实现对空隙的填充,完成水库堆石重力坝的施工。文中通过实例分析,该技术可以大大提高堆石重力坝的施工效率,缩短施工周期,减少建设成本,从而增加效益。

In order to solve the problem of low efficiency of void filling construction of rockfill gravity dam, the construction method of self-compacting concrete masonry is proposed, that is, large particle size blocks are first put into the silo surface to form a rockfill silo surface with large pores, and then self-compacting concrete is poured to fill the void and complete the construction of rockfill gravity dam in reservoir. Through the analysis of examples, the technology can greatly improve the construction efficiency of rockfill gravity dam, shorten the construction period, reduce the construction cost, and increase the benefit.
