The spacing between the platform frames 2 is 2m, and the bottom platform frame can be set to be 40cm from the ground. A supporting steel pipe 5 is arranged on the platform frame 2, and a 3mm thick patterned steel plate is laid on the upper part of the supporting steel pipe 5, wherein the patterned steel plates 7 located at the two arc-shaped ends of the platform frame 2 are movable longitudinally (i.e., the patterned steel plates 7 can be moved along the length direction of the pier body), and the patterned steel plates 8 located on the inner side of the two arc-shaped ends of the platform frame 2 are divided into two rows along the longitudinal direction, and an adjustment space 14 is left between the two rows of patterned steel plates 8, and the two rows of patterned steel plates 8 are both movable transversely (i.e., the patterned steel plates 8 can be moved along the width direction of the pier body). A detachable steel bar slot 6 is arranged at the outer edge of the patterned steel plate on each layer of the platform frame 2. The steel bar slot 6 is made of angle steel, and is provided with a groove that can be engaged with the steel bar. The spacing of the grooves is determined according to the design spacing of the main reinforcement of the pier body. The steel bar slot 6 can be fixed to the edge of the patterned steel plate by bolts in sections, and a circle of steel bar slots can be formed around the platform. When tying the pier body reinforcement, the main reinforcement is positioned by the groove on the steel bar slot 6. Five telescopic adjustment rods 3 are provided at the two arc-shaped ends of each layer of the platform frame 2, and the five telescopic adjustment rods 3 at each arc-shaped end are evenly arranged in a radial pattern along the arc-shaped end of the platform frame 2. The telescopic adjustment rod 3 includes a threaded sleeve 3.1 and a screw 3.2 screwed to the threaded sleeve 3.1, the threaded sleeve 3.1 is fixedly arranged on the platform frame 2, and the outer end of the screw 3.2 is connected to a U-shaped fixture 3.3. A vertically arranged square tube 4 is detachably connected between the U-shaped fixtures 3.3 of the upper and lower corresponding telescopic adjustment rods 3. The length of the screw 3.2 can be adjusted by rotating the screw 3.2.

[0024] In order to facilitate the adjustment of the lateral position of the two rows of patterned steel plates 8, at least one width adjustment mechanism 9 is preferably provided between the two rows of patterned steel plates 8, and the width adjustment mechanism 9 includes an adjustment screw 9.1 and two support plates 9.2 with screw holes. The adjustment screw 9.1 adopts a screw with a diameter of φ18 mm, and the two ends of the adjustment screw 9.1 are provided with screws, and the screw threads at the two ends are rotated in opposite directions.
