[0009] In a possible design, four stoppers for preventing the brackets from moving are fixedly connected to the inner wall of the arc-shaped plate, and the four stoppers are respectively located above and below both sides of the two brackets.

[0010] In the present application, when supporting a square column, the corners of the column are matched with the intersection of the brackets, and the column is fixed on the column by welding or bolting, and then the column and the device are placed in the pile hole by hoisting. The outer walls of the arc plates are in contact with the inner walls of the pile holes to prevent the square column from tilting, and the anti-rotation blocks are embedded in the inner walls of the pile holes to prevent the column and the device from rotating. When supporting a circular column, the circular column is attached to one side of the two brackets, and the column is fixed on the column by welding or bolting, and then the column and the device are placed in the pile hole by hoisting.
