Deep foundation pit multi-form inner support construction method and system
The invention discloses a deep foundation pit multi-form inner support construction method and system.The construction method adopts multiple corresponding deep foundation pit supporting modes for reasonable optimization design, and when original supporting piles adjacent to one side of an existing building and remaining anchor cables conflict with existing foundation pit construction, the forms of floor number reduction, one-pass supporting and section steel support replacement are adopted; the influence of the anchor cable on foundation pit construction is avoided through the change of the structure and the support type; when the original support pile adjacent to one side of the existing building and no anchor cable conflict exist, the design of two floors and one support is adopted, and the number of supports in the adjacent anchor cable-free foundation pit area is reduced; when no building exists adjacent to other sides of the foundation pit, the overall safety and stability of the deep foundation pit are effectively ensured by adopting the design of two supports and two floors; on the premise that safety and stability of the deep foundation pit are guaranteed, the problems that anchor cable supports of an existing deep foundation pit and an old foundation pit conflict, and an underground structure of a new building also conflicts with the existing deep foundation pit are solved.
本发明公开了一种深基坑多形式内支撑施工方法及系统，该施工方法采取多种对应深基坑支护方式合理优化设计，当邻近已有建筑一侧原有支护桩且遗留锚索与现基坑施工冲突时采用缩减楼层数、一道支撑和型钢换撑的形式，通过结构与支护型式的变化来避免锚索对基坑施工的影响；当邻近已有建筑一侧原有支护桩且无锚索冲突时采用两层楼和一道支撑的设计，减少了相邻无锚索基坑区域的支撑道数；基坑其它侧邻近无建筑物时采用两道支撑和两层楼的设计来有效确保深基坑整体的安全稳定；在确保深基坑安全稳定的前提下，解决了现深基坑与旧基坑的锚索支护存在冲突，以及新建筑地下结构也与其存在一定的冲突的问题。
