摘要
建昌营铁东煤矿风井井筒冻结段双层钢筋混凝土井壁解冻出水后 ,采用壁间注浆 ,辅以壁后注浆 ,文中着重介绍了立井井壁后注浆施工技术 ,并对几个有关后注浆的问题进行有价值的分析论述。
When double_layer steel concrete shaft wall pours water after thawing at shaft frozen section, adopt wall clearance grouting and follow_up grouting.In this paper,mainly introduce shaft follow_up grouting construction technology and expounds some problems after follow_up grouting.
