[0010] Furthermore, a handle is provided at one outer end of the support rod.

[0011] The beneficial effects of the utility model are:

[0012] 1. The utility model includes a frame, and support rods are arranged on the four sides of the frame, which pass through the side of the frame and are slidably connected to the side of the frame. An arc plate is arranged at one end of the inner side of the support rod to match the steel cage, and a number of cross bars for supporting the steel cage and strengthening the steel bars are evenly arranged on the inner arc surface of the arc plate. Before lowering the steel cage, the clamp is placed at the hole position, and then the steel cage is lowered by a crane. When the steel cage needs to be connected to the next section of the steel cage, the four support rods are extended, and the cross bars are stuck in the reinforcing steel bars of the steel cage to support the steel cage. It has excellent rigidity and can be used for supporting and positioning steel cages with large pile diameters and long piles. It is easy to use, safe in operation, improves construction efficiency, and prevents the casing from sinking. BRIEF DESCRIPTION OF THE DRAWINGS
