The foundation reinforcing device comprises a fixing rod, pouring holes are formed in the outer wall of the fixing rod, the pouring holes are a plurality of sets of circumferential arrays, the outer wall of the fixing rod is fixedly connected with a telescopic rod, one side of the telescopic rod is fixedly connected with a limiting plate, the limiting plate is of an arc-shaped structure, and the top of the fixing rod is fixedly connected with a supporting plate; the top of the supporting plate is fixedly connected with a supporting base. According to the device, the telescopic rods have certain elasticity, the limiting plates are arranged on the outer sides of the telescopic rods, each limiting plate is of an arc-shaped structure and tightly attached to the inner wall of the foundation pit, and the telescopic rods and the limiting plates are distributed on the outer wall of the fixing rod in a multi-group circumferential array mode, so that the fixing rod in the center can be fixed to the center of the foundation pit, and the fixing rod is prevented from inclining. Due to the existence of the outer wall telescopic rods and the limiting plates, stress on the periphery of the fixing rods is uniform, and meanwhile in the later pouring process, the contact area between the fixing rods and concrete can be increased due to the existence of the telescopic rods and the limiting plates.

本发明公开了一种地基加固装置，包括固定杆，固定杆的外壁开设有浇筑孔，浇筑孔为多组圆周阵列，固定杆的外壁固定连接有伸缩杆，伸缩杆的一侧固定连接有限位板，限位板为弧形结构，固定杆的顶部固定连接有支撑板，支撑板的顶部固定连接有支撑座。本发明中，伸缩杆具有一定的弹性且伸缩杆外侧设置有限位板，限位板为弧形结构且紧贴基坑的内壁，由于伸缩杆与限位板为多组圆周阵列分布在固定杆的外壁，因此可将中心处的固定杆位置固定在基坑的中心，防止固定杆位置的歪斜。外壁伸缩杆与限位板的存在，使得固定杆的四周受力较为均匀，同时在后期的浇筑过程中，伸缩杆与限位板的存在也会增加固定杆与混凝土的接触区域。
