【摘要】 近年来,堆石自密实混凝土施工技术在混凝土重力坝施工中应用日渐广泛。本文结合工程实例,对石料筛选冲洗、仓面堆石、模板设计架设、自密实混凝土配合比选择、混凝土拌制、入仓浇筑等关键工序及堆石自密实混凝土重力坝施工技术的完善措施和常见问题进行阐述,总结分析了技术要点,供类似工程参考。更多还原

【Abstract】 The construction technology of rockfill self-compacting concrete is used in the construction of concrete gravity dams more and more widely in recent years. The engineering example is combined in the paper for describing stone screening and washing, warehouse stone piling, template design construction, choice of self-compacting concrete mixture ratio, concrete mixing, warehousing pouring and other key processes, measures for perfecting the stone self-compacting concrete gravity dam construction technology as well as come problems. Main technical points are analyzed and summarized, thereby providing reference for similar projects.更多还原
