[0033] Step 302, hoist and lower the lattice column 200 and the steel cage of the engineering pile connected thereto as a whole, so that the lattice column 200 is hoisted and lowered between the ground and the pile driver platform thereon. In order to improve the stability of the hoisted lattice column 200, a cross bar can be passed through the lattice column 200 to suspend it on the ground.

[0034] Step 303 , hoisting the guide frame 110 above the lattice column 200 , making the axis of the guide frame 110 coincide with the axis of the lattice column 200 , and detachably connecting the guide frame 110 to the top of the lattice column 200 .

[0035] Step 304, on the floor, the lattice column 200 and the steel cage of the engineering pile connected thereto are hoisted and lowered as a whole through the positioning hanging rod 120 and the hoisting ring 130 at the upper end thereof, so that the lattice column 200 is hoisted and lowered below the floor, and during the hoisting and lowering process of the lattice column 200, the positioning direction of the lattice column 200 is guided and corrected through the guide frame 110, and the positioning of the lattice column 200 is determined through the positioning of the guide frame 110, so that the guide frame 110 is partially located above the floor and partially located below the floor.
