建筑施工中基坑支护结构加固技术探究

Research on Strengthening Technology of Foundation Pit Supporting Structure in Building Construction

为减小基坑支护结构各测点垂直方向的位移量,提高支护结构承载力和建筑工程质量,文中通过设计基坑支护加固体柱结构、填土加固处理、基础土方开挖与拔除加固体柱等步骤,设计了一种新的建筑施工中基坑支护结构加固技术。应用该技术后,各个监测点垂直方向的位移量得到了有效控制,使得支护结构的承载力得到提升。

In order to reduce the displacement of each measuring point in the vertical direction of the foundation pit support structure, improve the bearing capacity of the support structure and the quality of the construction project, a new reinforcement technology of the foundation pit support structure in the construction is designed through the steps of designing the foundation pit support plus solid column structure in this paper, filling reinforcement treatment, foundation earthwork excavation and pulling out the reinforced column. After the application of this technology, the vertical displacement of each monitoring point has been effectively controlled, so that the bearing capacity of the support structure has been improved.
