玛尔水电站大坝混凝土入仓方式选择

Selection of Construction Warehousing Ways of Mahl Hydropower Station

玛尔水电站拦河坝采用碾压混凝土重力坝,碾压混凝土施工方案是大坝快速施工的关键,直接影响到工程的工期和投资。该文根据工程地形地质条件和枢纽布置特点,结合施工导流规划和施工进度安排,拟定了多种碾压混凝土入仓手段,提出采用自卸汽车、负压溜槽、皮带机、布料机和缆机等方式入仓的施工方案,结合对典型坝段浇筑上升高度分析,结果表明所选施工方案是可行、合理的。

The barrage of Mahl hydropower Station is RCC gravity dam. The construction scheme of RCC dam is the key to high-speed construction,directly affecting on project schedule and cost. According to the topographic and geological conditions and layout of project,combined with construction diversion planning and construction schedule arrangement,this article drew up a few ways of RCC construction,such as dumper,negative pressure trough,belt conveyer,placing booms,cable crane. Combined with analysis of rising height of typical dam,the result shows that the selected construction scheme is feasible and reasonable,and it＇s potential reference for other similar projects.
