[0031] An annular flange 5 is integrally formed on the inner wall of the pipe pile body 1 above the supporting structure, and a limiting groove 6 is left between the lower surface of the annular flange 5 and the supporting structure.

[0032] The pipe core pile includes a steel cage embedded in the inner cavity of the pipe pile body 1, and also includes a core column 11 formed by pouring concrete in the gap between the steel cage and the inner wall of the pipe pile body 1. The portion of the core column 11 located in the inner cavity of the limiting groove 6 is solidified to form a clamping portion 12 clamped with the limiting groove 6. The clamping portion 12 is used to clamp inside the limiting groove 6 to form a clamping structure, which greatly increases the stability of the connection between the core column 11 and the pipe pile body 1.

[0033] Reference Figure 1 The supporting structure includes a supporting plate 2 having a diameter equal to the inner diameter of the pipe pile body 1, and a limiting device for limiting the supporting plate 2 is provided below the supporting plate 2. The supporting plate 2 is used to form a cylindrical mold together with the inner wall of the pipe pile body 1, so that the user can pour concrete on the supporting plate 2 to pour the core column 11.

[0034] Reference Figure 1 The limiting device is a plurality of support rods 3 penetrating the pipe pile body 1 perpendicular to the height direction of the pipe pile body 1, the upper surface of the support rod 3 abuts against the lower surface of the support plate 2, and sealing rings are installed at the connection between the two ends of the support rod 3 and the pipe pile body 1. The support rods 3 are provided to support the support plate 2 from below, and the sealing rings are provided to seal the connection between the support rods 3 and the pipe pile body 1, thereby improving the sealing performance of the connection between the support rods 3 and the pipe pile body 1.

[0035] Reference Figure 1 and Figure 3The upper surface of the support plate 2 is also provided with a sealing ring 4 in an annular structure. The sealing ring 4 in an annular structure is used to reseal the gap between the peripheral side of the support plate 2 and the inner wall of the pipe pile body 1, so as to prevent groundwater from entering the upper part of the support plate 2 through the gap between the support plate 2 and the pipe pile body 1, thereby affecting the user's pouring of the core column 11.

The tie bars 8 and the hoop bars 9 together form a steel cage embedded in the core column 11, which is used to improve the supporting performance of the core column 11. The curved portion 10 is formed by bending the bottom end of the tie bar 8 to reinforce the clamping portion 12 extending into the limiting groove 6.

[0038] Reference Figure 2 and Figure 3 The bottom end of the core column 11 extends into the inner cavity of the sealing ring 4 to form an expansion portion 13. Before the expansion portion 13 is cast in the sealing ring 4 and not solidified, the fluidity of the concrete can squeeze the sealing ring 4 toward the circumference, thereby improving the sealing performance of the sealing ring 4.

Since an annular flange 5 is integrally formed in the inner cavity of the pipe pile body 1, a limiting groove 6 is formed between the annular flange 5 and the support plate 2. The poured core column 11 has fluidity before being fixed on the plate, and can enter the limiting groove 6. After being fixed on the plate, the clamping part 12 is formed to clamp with the pipe pile body 1, which greatly improves the stability of the connection between the core column 11 and the pipe pile body 1, and avoids the problem that the existing pipe pile structure is fixed only by the friction between the core column 11 and the inner wall of the pipe pile. After a long time, as the core column 11 wears, the friction between the core column 11 and the inner wall of the pipe pile gradually decreases, and the core column 11 is easily pulled out of the pipe pile after being stressed.
