The effect achieved by the above components is: the four groups of mounting plates 21 are installed using the above technical scheme, which is convenient for the subsequent support mechanism 3 to be installed on the mounting mechanism 2, and its structural characteristics are used in conjunction with the support mechanism 3.

[0030] In this embodiment: an installation cavity 22 is formed between each group of installation plates 21, and the support mechanism 3 is slidably connected in the four installation cavities 22. The support mechanism 3 includes a first support plate 31 and a second support plate 32 that are identical and vertically distributed. The first support plate 31 and the second support plate 32 are welded at the intersection of the first support plate 31 and the second support plate 32. The longitudinal sections of the first support plate 31 and the second support plate 32 match the installation cavity 22, and the two ends are respectively slidably connected in the four installation cavities 22. The effects achieved by the above components are: the first support plate 31 and the second support plate 32 can stably support the opposite side walls of the steel casing 1, and there will be no gap between the first support plate 31 and the second support plate 32 and the side walls of the steel casing 1, thereby ensuring the structural stability of the steel casing 1 during hoisting and use, and avoiding deformation of the steel casing; the first support plate 31 and the second support plate 32 are welded at the intersection of the first support plate 31 and the second support plate 32, which improves the stability of the support mechanism 3; the first support plate 31 and the second support plate 32 can be stably installed in the installation cavity 22 without shaking.

Then, the steel casing 1 is compacted and positioned using an excavator, and the area around the steel casing 1 is backfilled to ensure that the position and elevation of the steel casing 1 are accurate. Then, the screw 26 is rotated inversely to unscrew the screw 26 from the threaded hole 33, and the limit plate 24 is pulled out of the limit groove 23 through the movable plate 25. Then, the first support plate 31 and the second support plate 32 are pulled out from the installation cavity 22, and then a steel frame is constructed inside the steel casing 1 and concrete is poured.
