浅析构皮滩水电站岸坡坝段无盖重固结灌浆试验

Consolidation Grouting Test in Non Concrete Layer Foundation in Dam Section on Bank Slope of Goupitan Hydropower Station

为减少构皮滩水电站岸坡坝段混凝土浇筑与有盖重基础固结灌浆之间的施工干扰,通过无盖重基础固结灌浆施工工艺试验论证灌浆效果,进一步明确了无盖重基础固结灌浆的布孔方式、灌浆压力等技术参数和施工工艺,从而指导了构皮滩水电站岸坡坝段的无盖重基础固结灌浆施工。

In order to reduce construction interference of concrete placement with concrete layer foundation consolidation grouting in dam section on bank slope of Goupitan hydropower station , construction technique of non concrete layer foundation consolidation grouting is applied to prove grouting effects. Hole patterns and grouting pressures of non concrete layer foundation consolidation grouting are further confirmed so as to give guidance to non concrete layer foundation consolidation grouting construction in dam sections on both bank slopes of Goupitan hydropower station.
