Abstract:

Due to the poor geological condition and serious seepage at the dam site of Miaowei Hydropower Station, the curtain grouting must be carried out. To ensure the curtain construction quality and provide design parameters for practical construction, the seepage control test of curtain grouting was conducted. This paper introduces the design scheme of grouting hole, check hole, uplift observation hole, construction procedure, the measures taken for special problem in the test and its effects. The seepage control test of curtain grouting achieved success and provided detail data for design and construction of curtain grouting.
