The invention relates to the technical field of foundation pit supporting, and discloses a row pile cantilever structure for foundation pit supporting. In order to improve the supporting stability of a row pile cantilever, longitudinal reinforcing ribs are arranged in foundation piles, transverse reinforcing ribs sleeve the outer sides of the longitudinal reinforcing ribs, protection mechanisms are symmetrically fixed to the inner walls of the foundation piles, and jacking and supporting mechanisms are fixedly connected to the top ends of the foundation piles. According to the row pile cantilever structure for the foundation pit supporting, soil on the two sides of a foundation pit is isolated and protected through the protection mechanisms, and the situation that the soil slides off in a large area due to rainwater, external pressure and the like can be effectively prevented; and meanwhile, the rainwater in the soil can be leaked out through the protection mechanisms, the situation that the foundation piles are unstable in supporting and inclined due to the fact that the rainwater is located in the soil for a long time is avoided, in the row pile cantilever supporting process, the supporting stability of the foundation piles can be improved by jacking and supporting the foundation piles through the jacking and supporting mechanisms, and the foundation piles are prevented from being crushed by active pressure from the top of the foundation pit.
本发明涉及基坑支护技术领域，公开了一种用于基坑支护的排桩悬臂结构，为了提高排桩悬臂的支护稳定性，所述基桩的内部设置有纵向加强筋，所述纵向加强筋的外侧套接有横向加强筋，所述基桩的内壁对称固定有防护机构，且基桩的顶端固定连接有顶撑机构。本发明通过防护机构对基坑两侧泥土的隔离防护，能够有效的防止由于雨水、外界压力等导致泥土出现大面积滑落的情况，同时能够使泥土中的雨水通过防护机构渗漏出，避免雨水长久处于泥土中，导致基桩出现支护不稳、倾斜的情况，在排桩悬臂支护过程中，通过顶撑机构对基桩的顶撑支护，能够提高基桩的支撑稳定性，防止来自基坑顶部的主动压力压垮基桩。
