Deformation-preventing deep foundation pit reinforcing structure

The utility model discloses an anti-deformation deep foundation pit reinforcing structure, and relates to the technical field of foundation pit supporting, the anti-deformation deep foundation pit reinforcing structure comprises a foundation pit side plate, a frame limiting column is arranged on one side of the foundation pit side plate, a limiting mechanism is arranged on the outer side of the frame limiting column, and the limiting mechanism is used for positioning and discharging the frame limiting columns with different widths. According to the technical scheme, after foundation pit excavation is completed through the vertically-positioned frame limiting columns, separation or deformation of the right-angle-contact frame limiting columns is avoided, a supporting mechanism is arranged on the other sides of the frame limiting columns, the supporting mechanism adjusts the distance between the frame limiting columns according to the use requirement, and the deformation condition is avoided. When the side plat
