某水电站上下游围堰采用基础全封闭塑性混凝土防渗墙上接土工膜斜墙的土石围堰,以适应松散透水地基及复杂的水文地质条件和工程地质条件。该围堰塑性混凝土原材料的选择、配合比的设计、塑性混凝土适应性生产等方面的经验,可为相关工程提供参考。经检查,该围堰塑性混凝土的质量达到优秀水平。
The cofferdam at the upstream and downstream of a hydropower station adopts earth-rock cofferdam with geomembrane sloping wall on the basis of fully enclosed plastic concrete cut-off wall to adapt to loose permeable foundation and complex hydrogeological conditions and engineering geological conditions. The cofferdam plastic concrete raw material selection, with the ratio of design, plastic concrete adaptability of production experience, can provide reference for related projects. After examination, the cofferdam plastic concrete quality to achieve excellent levels.
