Construction method for dispersing side load of elevator shaft foundation pit
The construction method comprises the steps that a plurality of component force plates A and a plurality of component force plates B are oppositely supported on a plurality of steel sheet piles, and a stress system for dispersing the side loads of the elevator shaft foundation pit is constructed; and the multiple telescopic pieces A and the multiple telescopic pieces B are controlled to extend by different lengths to abut against the steel sheet piles, so that the multiple component force plates A and the multiple component force plates B make contact with the multiple steel sheet piles to be stressed, and when the inclined steel sheet piles are centralized, pressure loads generated by the sludge foundation on the side edge of the elevator shaft foundation pit are dispersed to the multiple steel sheet piles. The multiple component force plates A and the multiple component force plates B make contact with multiple steel sheet piles to obtain a stress foundation, pressure loads generated by a sludge foundation on the side edge of an elevator shaft foundation pit are dispersed, the inclined steel sheet piles are righting, and the problem that the steel sheet piles needing to be righting deform due to large single-point stress is solved.
本发明公开了一种分散电梯井基坑侧边载荷的施工方法，包括：多个分力板A、多个分力板B对向支撑在多个钢板桩上，构建出分散电梯井基坑侧边载荷的受力体系；控制多个伸缩件A、多个伸缩件B伸长出不同的长度顶着钢板桩，使多个分力板A及多个分力板B对多处钢板桩接触受力，对倾斜的钢板桩进行扶正时，电梯井基坑侧边淤泥基础产生的压力载荷被分散到多个钢板桩上。多个分力板A及多个分力板B对多处钢板桩接触获得受力基础，让电梯井基坑侧边淤泥基础产生的压力载荷分散，实现对倾斜的钢板桩进行扶正，解决了需扶正的钢板桩单点受力多大发生变形的问题。
