Method for whole removal of partition wall in deep foundation pit
By installing servo jacks on the partition walls in deep foundation pits using a servo hydraulic jack system, the load can be smoothly transferred and monitored in real time. This solves the problems of cumbersome demolition procedures and unstable structural stress in deep foundation pits, and improves construction efficiency and safety.

Abstract
本发明提供了一种深基坑中隔墙整体拆除施工方法，包括步骤：浇筑地下主体结构最下层结构的结构主梁；在结构主梁标高位置，在中隔墙上开凿尺寸大于伺服千斤顶外径的洞口；洞口内装伺服油顶系统并连接中央控制室；伺服千斤顶两端同步顶紧中隔墙两侧的结构主梁；从基坑顶部从上至下整体拆除地下一层的中隔墙，并对地下一层的结构主梁进行混凝土浇筑补缺；由上至下依次完成各层的中隔墙拆除和结构主梁的混凝土浇筑补缺。本发明涉及土木工程施工技术领域，能够解决现有技术中中隔墙拆除工序繁琐、在两侧基坑的不同阶段沉降差异导致两侧结构受力不稳定的问题。
