[0057] In the embodiment, the material of the reinforcement cage 2 is steel; the number of the prestressed steel bars 20 can be 6, 8, 12 or more, for example, in some embodiments, as shown in FIG. 2, the number of the prestressed steel bars 20 is 8, so that the cost is reduced without reducing the strength, and the high strength and low cost requirements of the reinforcement cage 2 are met. Figure 2 The connection mode between the hoop 21 and the prestressed steel bars 20 can be welding, bolt connection, riveting, etc.
[0058] The reinforcement cage 2 has high strength, is arranged along the length direction of the pile body 1, can provide circumferential constraint to the pile body 1, can improve the shear strength of the pile body 1, makes the pile body 1 have good ductility, the pile body 1 is not easy to deform, can make the pile body 1 more resistant to compression along the axial direction, and has high practicability. The axial compression resistance and side friction of the pile body 1 are improved by the reinforcement cage 2, the single pile bearing capacity is higher, and the practicability is better.
[0059] Referring to FIG. 1, Figures 1-2 The maximum width of the assembly recess 11 is 1 / 2-1 / 10 of the width of the pile body 1; in the embodiment, the maximum width of the assembly recess 11 is 1 / 2 of the width of the pile body 1, and the assembly recess 11 is symmetrically arranged on both sides of the pile body 1, thereby improving the adaptability of the support pile. In the embodiment, the assembly recess 11 is naturally formed during preparation, that is, a partition plate is pre-installed between the positions where the two pile bodies 1 are formed in the mold, so as to facilitate the separation of the two pile bodies 1, and the assembly recess 11 is formed by the protrusions pre-installed in the core-pulling preparation mold.
[0060] Referring to FIG. 1, Figure 3 , Figure 3This is a cross-sectional view (II) of a support pile according to an embodiment of the present invention. Specifically, the reinforcing cage 2 also includes multiple threaded reinforcing bars 22 extending along the length of the pile body 1, with the multiple threaded reinforcing bars 22 close to the backwater side of the pile body 1. The threaded reinforcing bars 22 are located between adjacent prestressed reinforcing bars 20, and the multiple threaded reinforcing bars 22 and the multiple prestressed reinforcing bars 20 are connected by stirrups 21. The present invention increases the structural strength of the support pile by providing multiple threaded reinforcing bars on the backwater side of the pile body. At the same time, the multiple threaded reinforcing bars and the multiple prestressed reinforcing bars are connected by stirrups.

Furthermore, compared to a conventional circular transition arc, an elliptical or parabolic transition arc 4 has a greater rate of change with the side of the pile body 1, making demolding during production easier and improving production efficiency and yield.
