[0031] The above-mentioned method for making ground screw steel pipe piles is characterized in that the steps of the making method are as follows: (1) Selecting and installing the mandrel 4: Selecting a mandrel 4 of corresponding size according to the parameters of the ground screw to be prepared, and clamping the front end of the mandrel 4 in the clamping groove, and clamping the rear end of the mandrel 4 by the clamping claws on the chuck 10; (2) Adjust the position of the driving roller 17 and make it fit with the side wall of the mandrel 4: adjust the position of the driving roller 17 by the lifting motor 18, insert the L-shaped steel belt 1 into the driving roller 17, and press the steel belt 1 against the side wall of the mandrel 4; (3) Adjusting the position of the welding head rod 36: adjusting the position of the welding head rod 36 to contact the side of the steel strip 1; (4) Winding: The end point of the steel strip 1 is welded to the core rod 4 through the gun head of the welding gun at the end of the welding head rod 36, and then the rotating motor 11 and the sliding motor 12 are started. The rotating motor 11 drives the core rod 4 to rotate, and the sliding motor 12 drives the slide plate 3 to move, thereby driving the steel strip 1 to be wound on the core rod 4, and welding is performed while winding.

The glue can melt when it comes into contact with water. At the same time, it also avoids the welding of the welding seam with the core rod during the winding welding process, which affects the demolding. In the above scheme, a steel strip 1 with an L-shaped cross-section is wound to form an integral ground screw. This method is simple, and the ground screw can be prepared by winding, which saves costs and has high processing efficiency. Moreover, under the pressure of the roller surface of the driving roller 17 contacting the side of the core rod 4, the core rod 4 rotates at the same time, so that the winding of the steel strip 1 can be realized, and the stretching process of the steel strip 1 is also realized during the winding process. Due to the adoption of the above-mentioned structure, the present invention has the advantages of simple structure, simple manufacturing method, cost saving, and high processing efficiency.

The tooling for making ground screw steel pipe piles according to claim 4 is characterized in that The core rod comprises a conical rod and a round rod, the conical rod and the round rod are integrally connected, and the outer walls of the conical rod and the round rod are wrapped with a solid layer, which is a structural layer that can be melted with water, and the thickness of the structure is 2-5mm.
10. A method for manufacturing ground screw steel pipe piles, characterized in that The steps of making the method are as follows: (1) Select and install the mandrel: Select a mandrel of corresponding size according to the parameters of the ground screw to be prepared, and clamp the front end of the mandrel in the slot, and clamp the rear end of the mandrel with the claws on the chuck; (2) Adjust the position of the driving roller and make it fit with the side wall of the mandrel: adjust the position of the driving roller by the lifting motor, insert an L-shaped steel belt into the driving roller, and press the steel belt against the side wall of the mandrel; (3) Adjust the position of the welding head rod: adjust the position of the welding head rod to contact the side of the steel strip; (4) Winding: The end point of the steel strip is welded to the core rod through the gun head of the welding gun at the end of the welding head rod, and then the rotating motor and the sliding motor are started. The rotating motor drives the core rod to rotate, and the sliding motor drives the slide plate to move, thereby driving the steel strip to be wound on the core rod, and welding is performed while winding. Since the core rod includes a conical rod and a round rod, the lifting motor adjusts the height between the driving roller and the side of the core rod in the conical rod part, and the flipping motor adjusts the inclination angle of the driving roller. The lifting motor gradually drives the driving roller to move upward to complete the winding of the conical rod part. After the round rod part after the conical rod part, the flipping motor drives the driving roller to a horizontal state. The lifting motor rises until the driving roller contacts the side of the round rod to complete the winding of the round rod part, and finally welds it into a ground screw shape; (5) Demolding: knock off the welding part between the end point of the steel strip and the core rod, place the core rod and the wrapped steel strip in water, melt the structure, and then pull out the core rod.
