Deep foundation pit prestress support changing structure and construction method
The invention discloses a deep foundation pit prestress support changing structure and a construction method. The deep foundation pit pre-stress support changing structure mainly comprises a foundation slab pre-stress support changing structure and a main body structure floor pre-stress support changing structure, and automatic supporting axial force monitoring and automatic horizontal displacement monitoring of deep soil outside a pit are combined; additional internal force and additional deformation of the foundation pit due to support dismounting are actively compensated, the safety of support dismounting of the foundation pit is effectively improved, and the construction efficiency and progress of the foundation pit are guaranteed.
本发明公开了一种深基坑预应力换撑结构及施工方法。该深基坑预应力换撑结构主要包括基础底板预应力换撑结构与主体结构楼板预应力换撑结构，结合自动化支撑轴力监测与自动化坑外深层土体水平位移监测，通过逐级施加千斤顶顶力，主动补偿基坑由于拆撑出现的附加内力与附加变形，有效提高了基坑拆撑的安全性，保障了基坑施工效率与进度。
