摘要
为了满足大坝碾压混凝土对砂子含粉量从原来的 12 %提高到 15 %± 1%、且 <0 0 8mm含量达 8%以上的新要求 ,大朝山电站人工砂石系统在不降低原生产能力和产品质量标准的前提下 ,因地制宜地建立了一套石粉回收系统 ,圆满地解决了大坝碾压混凝土用砂质量问题 ,取得了较好的经济效益和社会效益。
The dam for the Dachaoshan Hydropower Station requires that the sand of its RCC has the powder content increasing from 12% to 15%±1% and the content of powder diameter of less than 0 08 mm should be over 8% In order to meet this requirement, a powder recovery system was set up in the artificial aggregate system in the Dachaoshan Hydropower Station, according to the local conditions and under the prerequisite that the production capacity and quality standards of the original system could not be lowered Such recovery system has successfully solved the quality problem of the sand used by the RCC of the dam and has gained good economic and social benefits
