Foundation pit stand column underpinning method
The invention provides a foundation pit stand column underpinning method which comprises a stand column underpinning system, the stand column underpinning system comprises two underpinning stand columns, two first supporting piles and a joist assembly, the two underpinning stand columns are located on the two sides of a stand column to be underpinned, the two first supporting piles are arranged below the corresponding underpinning stand columns, and a second supporting pile is arranged at the bottom of the stand column to be underpinned; a supporting beam is arranged on the to-be-supported pipe stand column, and the lower portion of the supporting beam is connected with the two underpinning stand columns through a supporting beam assembly. The joist assembly comprises two longitudinal joists and four transverse joists, the two longitudinal joists are arranged on the two sides of the two underpinning stand columns respectively, and the longitudinal joists are arranged below the corresponding supporting beams in a supporting mode. The four transverse joists are arranged on the two sides of the corresponding underpinning stand columns and below the longitudinal joists in a supporting mode in pairs. The longitudinal joists are fixedly connected with the supporting beams through concrete pouring layers. The defects that in the prior art, an underpinning structure is complex, the underpinning cost is high, construction is difficult, the construction period is long, an existing supporting beam column system is prone to being damaged, and recycling cannot be achieved can be overcome.
本发明提供一种基坑立柱托换方法，其包括立柱托换系统，立柱托换系统包括二托换立柱、二第一支撑桩以及托梁组件，二托换立柱位于待托换立柱的两侧，二第一支撑桩设在对应的托换立柱下方，待托换立柱的底部设置有第二支撑桩；待托管立柱上设有支撑梁，支撑梁下方通过托梁组件与二托换立柱相连；托梁组件包括二纵向托梁和四横向托梁，二纵向托梁分别设在二托换立柱的两侧，且各纵向托梁支撑设在对应的支撑梁下方；四横向托梁分别两两一组托设在对应的托换立柱两侧以及纵向托梁下方；纵向托梁与支撑梁之间通过混凝土浇筑层固定连接。本发明能够解决现有技术托换结构复杂、托换成本高、施工困难且工期长、容易伤害已有支撑梁柱体系和不可回收等缺点。
