地下厂房无盖重固结灌浆封堵施工技术

Construction Technology of Coverless Reconsolidation Grouting Blocking for Underground Power House

山西省中部引黄泵站工程位于天桥地下泉域区,每年向黄河补水3.2×10^(8)m^(3),能否有效处理地下水,确保工程顺利进行是工程的关键点,地下泵站通过对底板进行无盖重垂直固结灌浆和边墙打斜孔进行固结灌浆以加强结构和形成有效的帷幕堵水,对有涌水钻孔进行封堵灌浆,确保工程质量和安全。

The middle part of Shanxi Province Yellow River Diversion Pump Station Project is located in the underground spring area of Tianqiao and provides 3.2×108m3 water to the Yellow River every year.Whether groundwater can be effectively treated and the project can be carried out smoothly is the key to the project.Underground pump station strengthens structure and forms effective curtain water shutoff by consolidation grouting without cover weight in vertical direction and oblique hole in side wall.At the same time,the blocking grouting is applied to the borehole with inrush water,which ensures the project quality and safety.
