Cast-in-situ bored pile deep foundation pit supporting structure and construction method
The invention relates to the technical field of deep foundation pit supporting, and particularly discloses a cast-in-situ bored pile deep foundation pit supporting structure and a construction method.The cast-in-situ bored pile deep foundation pit supporting structure comprises an inner support, and the inner support comprises a mounting cylinder, a multi-stage telescopic structure and an abutting plate; at least parts of the two multi-stage telescopic structures can stretch out of the two ends of the mounting cylinder and extend in the length direction of the mounting cylinder, and a driving mechanism, a locking mechanism and an unlocking mechanism are arranged in the mounting cylinder. The driving mechanism can adjust the length of the multi-stage telescopic structure, so that the abutting plates at the two ends abut against the inner wall of the deep foundation pit, and when the abutting plates firmly abut against the inner wall of the deep foundation pit, the locking mechanism limits the adjusting function of the multi-stage telescopic structure at the moment, so that the length of the multi-stage telescopic structure is kept fixed; and at the moment, the multi-stage telescopic structure can stably abut against the abutting plate to the inner wall of the deep foundation pit, and therefore stable supporting of the inner wall of the deep foundation pit is achieved.
本申请涉及深基坑支护技术领域，具体公开了一种钻孔灌注桩深基坑支护结构及施工方法，钻孔灌注桩深基坑支护结构包括内支撑，内支撑包括安装筒、多级伸缩结构以及抵压板，两组多级伸缩结构至少部分能够分别于安装筒的两端伸出并向安装筒的长度方向延伸，安装筒内设置有驱动机构、锁止机构以及解锁机构。驱动机构能够对多级伸缩结构的长度进行调节，使两端的抵压板与深基坑的内壁相抵接，当抵压板牢固的抵压在深基坑内壁上时，此时锁止机构对多级伸缩结构的调节功能进行限制，使多级伸缩结构的长度保持固定，此时多级伸缩结构即可稳定的将抵压板抵压在深基坑内壁上，以此来实现对深基坑内壁的稳定支撑。
