长调水电站混凝土面板堆石坝坝体填筑从坝料的开采、加工制备到上坝铺填碾压,实行全过程的质量控制。依照施工规范和设计要求,进行了堆石料的爆破、碾压试验及垫层料的制备、掺合级配试验。优选出一套合理的压实参数。施工中把好料源关,严格控制压实参数,加强取样检验,以保证坝体获得良好的填筑质量。
The dam foundation of the concrete face rockfill dam of Changjian Hydropower Station is filled with material from the mining of the dam material, processing and preparation to the filling of the upper dam, and the quality control of the whole process is implemented. In accordance with the construction specifications and design requirements, the blasting of rockfill materials, rolling test and the preparation of bedding materials, mixing grading test. A reasonable set of compaction parameters is preferred. Good material source during construction, strict control of compaction parameters, strengthen sampling inspection, in order to ensure the dam body to obtain a good quality of filling.
