In step S600, after the concrete is solidified, the concrete is fixedly connected with the lattice column, so that the lattice column is separated from the orifice limiting frame 100 after the lattice column is ensured not to sink, and then the construction of the lattice column can be completed, and then the lattice column limiting device is pulled out of the pile hole, and the lattice column limiting device can be used in the hoisting construction of the next lattice column.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
