[0032] The working principle and beneficial effects of the above embodiments are:

[0033] The supporting pile body 1 is designed with a gourd-shaped structure, enabling the supporting pile to effectively disperse and bear water pressure or soil pressure during the protection process, helping to resist the impact force of water flow. The connection of both side webs 12 to the middle web 11 in a gourd shape design makes the supporting pile body 1 have high stiffness and bending resistance in the horizontal direction;

[0034] The setting of the wing plates 14 enhances the lateral support force of the supporting pile, and the trapezoidal cross-section provides greater torsional resistance;

[0035] The transitional design of the first arc surface 13 and the second arc surface 15 makes the force transmission smoother, reduces stress concentration, and improves the stability of the supporting pile structure.

[0036] In one embodiment,

[0037] On the outer end surface of one side wing plate 14, a female tenon is longitudinally provided, and on the outer end surface of the other side wing plate 14, a male tenon is longitudinally formed. Both the female tenon and the male tenon are arranged along the axis of the middle web 11;

[0038] As Figure 4 shown, multiple supporting piles are interconnected through a mortise and tenon structure, enhancing the stability and impact resistance of the overall structure; both the female tenon and the male tenon are arranged along the axis of the middle web 11, making their connection along the main load-bearing direction of the supporting pile, thereby maximizing the utilization of the structure's strength.

The side of the wing plate 14 where the female tenon or the male tenon is provided corresponds to the short bottom side of the trapezoidal cross-section;

[0042] In one embodiment,

[0043] The above-mentioned supporting pile body 1 is a hollow structure; the hollow structure can effectively reduce the self-weight of the supporting pile body 1, reduce the pressure on the foundation, and at the same time reduce the material usage, thereby reducing costs.

The special-shaped stirrups 22 are adapted to the forming surfaces of the middle web 11 and the side web 12, which can ensure the stability of the steel cage body 2 in the concrete, and at the same time is conducive to the transfer and dispersion of the force of the formed retaining pile.

[0050] In one embodiment,

[0051] A wing plate steel cage 3 is arranged in the above-mentioned wing plate 14. The wing plate steel cage 3 includes a plurality of longitudinally arranged second main reinforcements 31 and U-shaped stirrups 32.
