深基坑邻近建筑物注浆加固技术
摘要:某建筑物距离地铁车站深基坑较近,在深基坑施工过程中建筑物产生了不均匀沉降,采用袖阀管注浆施工工艺对建筑物进行加固。通过对建筑物的基础形式进行调查,有针对性地选择注浆孔位,合理选取注浆参数,取得了较好的注浆效果,使建筑物沉降控制在允许范围内。
Abstract:Different settlement and large settlement occurred On the building adjacent to the foundation pit during theexcavation process of a metro station foundation pit. The sleeve value barrel grouting construction technologise was used to reinforcing the building. Byi investigating the form of the building foundation, we choose the grouting holes and selected the grouting parameter reasonably, made a good grouting effect, and controlled the building subsidence within permitted.
