ZHAO ZHIQIANG / ZHAO JINGLE / ZHAO BINGQIN / ZHAO DAWEI

The invention relates to the field of foundation pit supporting, in particular to a foundation pit supporting system and a construction method thereof. According to the key points of the technical scheme, the structure comprises a plurality of sheet piles which are fixed to a foundation pit and arranged on the pit walls of the two opposite sides of the foundation pit correspondingly, and the sheet piles are provided with fasteners; the reinforcing keels are movably buckled in the fasteners in the horizontal direction and used for enabling the multiple sheet piles to be in mutual stress association; the support assembly is located between the sheet piles on the two sides of the foundation pit, and a power assembly is arranged on the support assembly; the telescopic supporting assembly is detachably arranged on the support assembly, the two ends of the telescopic supporting assembly are each provided with a telescopic movable supporting part, the power assembly is connected with the telescopic supporting assembly, and the power assembly drives the two supporting parts to be close to or away from each other so that the two supporting parts can abut against reinforcing keels on the two sides of a foundation pit correspondingly; the sheet piles on the two sides of the foundation pit are supported, and the effect of improving the application benefits of the foundation pit supporting system is achieved.

本申请涉及基坑支护的领域，尤其是涉及一种基坑支护系统及其施工方法。其技术方案的要点是：包括若干块板桩，固定于基坑处并与分别布置于基坑相对的两侧坑壁处，所述板桩上具有扣件；加固龙骨，沿水平方向活动扣合于所述扣件中，用于将若干块板桩相互受力关联；支架组件，位于基坑两侧的板桩之间，支架组件上设有动力组件；伸缩支撑组件，可拆卸设置于所述支架组件上，两端分别具有可伸缩活动的支撑部，所述动力组件与所述伸缩支撑组件相连，所述动力组件驱动两组所述支撑部可相互靠近或远离，以使两组所述支撑部可分别与基坑两侧的加固龙骨相抵接，进而实现对基坑两侧的板桩进行支撑，本申请具有提升基坑支护系统应用效益的效果。
