摘要
龙江水电站枢纽工程建设监理部对大坝工程施工过程进行全方位的控制,严格审批配合比、施工措施,着重控制混凝土的原材料、拌和物、现场浇筑及通水冷却。坝体压水检查、钻孔取芯试验结果满足设计要求,55.35万m^3混凝土除前期出现极少裂缝外,后期无裂缝,表明质量控制达到较高的水准。
An approach of all-dimension control has been adopted by the supervising department during the construction of Longjiang Hydropower Station, who have given a strict approval to the mix proportion and construction options, with more emphasis on raw materials of concrete, mixture, on-site pouring and water pipe cooling. The test results of water pressing injection of dam body and core drilling are all satisfactory to the design requirement. Despite of a few cracks appeared in the early stage, the concrete pouring of 553 500 m3 are all up to the standard.
