9. The production system of the non-uniform-section spiral pipe pile according to claim 1, wherein: the cylindrical part comprises a main rib and a stirrup, the main rib is in a long strip shape, and the stirrup is in a circular ring shape;
the main reinforcements are arranged in a circular shape, the central axes of the stirrups are superposed with the central axis of the cylindrical part, the stirrups are fixedly connected with the main reinforcements, and the axes of the main reinforcements are parallel to the central axes of the stirrups;
the end plate is provided with a main rib hole, the main rib hole corresponds to the main rib, the main rib penetrates through the main rib hole, and the main rib is fixedly connected with the end plate.
10. The method for manufacturing the non-uniform-section spiral pipe pile based on the non-uniform-section spiral pipe pile production system of claim 8, is characterized in that: the method comprises the following steps:
placing a mold clack, placing a reinforcement cage into the placed mold clack, wherein the protruding part corresponds to the spiral cavity, smearing lubricating oil in the U-shaped groove of the torsion-resistant part, and filling a rubber strip with a steel wire rope;
injecting concrete into the placed mould halves, butting the other mould half with the placed mould half when the injection amount of the concrete meets the requirement, and fixedly mounting the two mould halves together;
starting the power part, driving the non-uniform section spiral tube type mould to rotate by the power part, and uniformly distributing concrete in the inner cavity of the non-uniform section spiral tube type mould;
and after the concrete is dried, disassembling one mould clack from the other mould clack, then removing the non-uniform section spiral pipe pile from the other mould clack, and finally drawing out the rubber strip with the steel wire rope from the U-shaped groove.
