建筑物纠偏加固是技术难度高、风险大的非常规工作,纠偏加固没有形成独立的理论体系,为了探索建筑物纠偏加固机理和施工方法,针对某小学综合楼设计施工概况及倾斜损坏情况,给出房屋所在地的工程地质简况,分析建筑物倾斜的原因,介绍掏土纠偏、房屋基础下淤泥质粉质黏土层注浆加固施工及监测过程,提出了纠偏加固过程中突发工程事故的处置办法。经掏土纠偏和注浆加固,房屋的倾斜率由17‰纠正为4‰,沉降不再有新发展。
The rectification and reinforcement of buildings is a non-routine work with high technical difficulty and high risk. There is no independent theoretical system for correction and reinforcement. In order to explore the mechanism of rectification and reinforcement of buildings and the construction method, aiming at the general situation of design and construction of the comprehensive buildings in primary schools, A brief introduction to the engineering geology of the location of the house, analysis of the cause of the tilt of the building, introduction of soil correction, grouting reinforcement construction and monitoring process of muddy silty clay layer under the house foundation, proposed disposal measures of sudden engineering accidents in the course of rectification and reinforcement . After digging soil correction and grouting reinforcement, the slope of the house was corrected by 17 ‰ to 4 ‰, no new development of settlement was found.
