江垭大坝自164m高程至200m高程采用RCC斜层铺筑法施工。经坝体钻孔压水及取芯检查,RCC的抗渗性及力学指标均满足设计要求。实践表明,RCC斜层铺筑工艺有效地解决了大仓面施工中浇筑能力不足和入仓混凝土停放时间长的问题,加快了施工速度,提高了施工质量
Jiangya Dam from 164m elevation to 200m elevation using RCC slab paving construction. After the dam body pressurized water and core inspection, RCC impermeability and mechanical indicators to meet the design requirements. The practice shows that the RCC inclined layer paving process effectively solves the problems of insufficient pouring capacity and long storage time of concrete entering the warehouse for the big noodle construction, accelerates the construction speed and improves the construction quality
