高坝洲水电站工程初步设计审查后,采纳了专家们提出的取消二期上游RCC过水围堰、坝体浇筑碾压混凝土并直接挡水的意见。为此,采取了一系列的工程措施和技术措施。为了确保坝体碾压混凝土的各项性能指标及施工质量达到设计要求,进行了三次现场试验。1999年5月中旬,高坝洲工程二期坝体碾压混凝土施工顺利结束,质量满足设计要求。采用RCC筑坝技术,加快了施工进度,取得了明显的经济效益。
After the preliminary design review of the Gaobazhou Hydropower Station project, the opinions put forward by experts to cancel the RCC over-water cofferdam in the upstream of the second phase, pouring RCC into the dam and directly retaining water were taken. To this end, adopted a series of engineering measures and technical measures. In order to ensure that all the performance indexes and construction quality of roller compacted concrete meet the design requirements, three field tests were carried out. In mid-May 1999, construction of the second phase of high dam dam RCC construction was successfully completed, the quality to meet the design requirements. The use of RCC dam construction technology, speed up the construction progress, and achieved significant economic benefits.
