乌江渡水电站的坝址为强岩溶灰岩,帷幕钻孔灌浆工程量达20万米,水泥平均单位耗量达293公斤/米,平均日耗量达100～150吨,最高班耗量达100吨;灌浆工程大部分要在长廊道内进行,施工条件差。在这种情况下,如果采用国内传统的单机分散制浆工艺,不仅要增加大量的劳动力,施工操作人员要受到矽尘的威胁,而且无法满足大耗浆量连续灌注的要求。为了解决这些问题,我局结合工程实际情况和
Dam site of Wujiangdu Hydropower Station is strong karst limestone. The project volume of curtain drilling grouting is 200,000 meters. The average unit consumption of cement reaches 293 kg / m. The average daily consumption reaches 100 ~ 150 tons and the highest class consumption reaches 100 Ton; most of the grouting works should be carried out in the corridor, poor construction conditions. In this case, if the traditional domestic single-machine distributed pulping process is adopted, not only a large amount of labor force needs to be added, but also the construction operator is threatened by the silica dust and can not meet the requirement of continuous pouring with a large consumption of slurry. In order to solve these problems, our bureau combined with the actual situation of the project
