Deep foundation pit supporting structure and deep foundation pit construction method
The invention provides a deep foundation pit supporting structure and a deep foundation pit construction method. The deep foundation pit supporting structure comprises a first steel inclined support and a second steel inclined support. In the support replacement construction process, the first steel inclined support and the second steel inclined support are sequentially mounted on an underground second-floor floor slab and an underground first-floor floor slab of a first foundation pit. During deep foundation pit construction, by means of the deep foundation pit supporting structure, the second foundation pit of the deep foundation pit can be excavated in advance when the underground second-floor floor slab construction in the first foundation pit is finished; and compared with a construction procedure that the second foundation pit is intelligently excavated after a first foundation pit basement structure is excavated by +/-0.00 in original foundation pit construction, thus the construction progress is accelerated, the underground structure construction period is reduced, and the influence of the space-time effect of foundation pit engineering on built buildings, pipelines, adjacent subways and the like of the surrounding environment is prevented.
本发明提供了一种深基坑支护结构及深基坑施工方法，所述深基坑支护结构包括第一钢斜撑和第二钢斜撑，在换撑施工过程中，所述第一钢斜撑和所述第二钢斜撑先后分别被安装于所述第一基坑的地下二层楼板上和地下一层楼板上。在进行深基坑施工时，使用本发明的深基坑支护结构可以实现将深基坑的第二基坑提前至第一基坑完成地下二层楼板施工时开始挖掘，相比原有基坑施工第二基坑智能在第一基坑地下室结构出±0.00后开挖的施工工序而言，加快了施工进度，缩短了地下结构施工工期，防止基坑工程的“时空效应”对周边环境的已建建筑、管线、邻近地铁等造成影响。
