莲花水电站大坝施工质量控制

莲花电站面板堆石坝从石料开采，加工制备到上坝填铺碾压，实行全过程的质量控制。依据规范和设计要求，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，优选出一套合理的碾压参数的检验压实密度的评定标准，从而为进行施工质量控制和检验压实质量提供了依据。在监控过程中，由大坝指挥部统一协调和研究解决质量或进度难题，以保证获得良好的填筑密实度。

Quality control or dam construction in Lianhua Hydropower Station

In the construction of the rockfill dam with concrete facing in the Lianhua Hydropower Station, the quality control has been conducted in the whole process from rock quarry, processing and manufacturing to The spread and roller compaction on the dam. According to the specification and design requirements, the rockfill materials blasting, compaction test, cushion materials manufacture and mixing gradation test have been conducted so that a set of roller compacting parameters and compaction density check have been obtained as the evaluation standards of construction quality control and compaction quality check. Meanwhile, in the process of monitoring and control, the dam headquarters has coordinated, studied and solved the problems of quality and progress so that a good filling density has achieved and some quality control measures and experience have been summarized.
