Anti-collapse supporting structure for deep foundation pit
The invention belongs to the technical field of foundation pit supporting, and particularly relates to an anti-collapse supporting structure for a deep foundation pit, the anti-collapse supporting structure comprises the foundation pit, a plurality of cast-in-place piles are fixedly arranged at the groove bottom of the foundation pit, the side walls of the cast-in-place piles are jointly and fixedly connected with a plurality of surrounding purlins, and a plurality of cable-stayed anchor rods are fixedly inserted into the surrounding purlins and the side wall of the foundation pit. A retaining wall is fixedly connected to the pit bottom of the foundation pit in an inserted mode, and a plurality of active supporting mechanisms are fixedly installed between the retaining wall and the multiple cast-in-place piles. By means of the method, the stability of row pile anchoring and pulling supporting can be improved, pressure can be applied according to soil layer collapse, supporting is actively strengthened, the supporting collapse prevention performance is improved, meanwhile, graded automatic triggering can be achieved, collapse buffering protection can be conducted on the outer edge of the interior of a foundation pit, field personnel can be reminded, the collapse danger degree can be reduced, and safety is improved.
本发明属于基坑支护技术领域，尤其是涉及一种用于深基坑的防坍塌支护结构，包括基坑，所述基坑的槽底固定设有多个灌注桩，各个所述灌注桩的侧壁共同固定连接有多个围檩，各个所述围檩与基坑的侧壁均固定插接有多个斜拉锚杆，所述基坑的坑底固定插接有挡土墙，且挡土墙与多个灌注桩之间固定安装有多个主动支护机构。本发明可以提高排桩锚拉支护的稳定性，并且可以依据土层坍塌施压，主动进行加强支护，提高支护防坍塌性能，同时还可以分级自动触发，在基坑内部外缘处，进行坍塌缓冲防护，既可以提醒现场人员，又可以降低坍塌危险程度，提高安全性。
