[0022] By uniformly distributing support rods and support plates within the concrete layer, the overall structural stability of the pipe pile is significantly improved. The combined action of support rods and support plates can more effectively resist external pressure and bending moment, thereby prolonging the service life of the pipe pile.

[0023] The design of through holes and notches on the support plate allows the concrete to flow smoothly during pouring, ensuring uniform distribution and tight filling of the concrete layer. This helps to reduce air bubbles and voids, improving the density and strength of the concrete.

[0040] Working principle:

[0041] The concrete layer 1 serves as the main load-bearing structure, responsible for bearing loads from above and outside. The support rods 5 are evenly distributed within the concrete layer 1, enhancing the overall stability of the concrete layer 1. They can disperse loads and prevent local damage to the concrete layer 1 when under stress. The support discs 4 are evenly distributed on the support rods 5, further enhancing the support capacity of the concrete layer 1. The design of the support discs 4 allows loads to be more evenly transmitted to the entire concrete layer 1, avoiding stress concentration.

[0042] When pouring the concrete layer 1, the concrete flows between the support discs 4 through the gaps 401 on the support discs 4. This design ensures that the concrete can uniformly fill the entire concrete layer 1, avoiding the generation of bubbles and voids. The density of the concrete is crucial to the load-bearing capacity of the pipe pile. Through reasonable gap 401 design, this scheme can effectively improve the density of the concrete, thereby enhancing the overall strength of the pipe pile.

[0043] The flange plates 3 and fixing holes 301 provided at both ends of the concrete pipe pile allow adjacent pipe piles to be conveniently connected and fixed by bolts. This connection method is not only simple and easy to implement, but also ensures the firmness and reliability of the connection. The flange plates 3 are fixed on both ends of the inner lining pipe 2 through the connection pipe 303, further enhancing the connection stability of the pipe pile. At the same time, the fixing discs 302 are embedded in the concrete layer 1, forming a firm overall structure with the concrete layer 1 and improving the uplift resistance of the pipe pile.

[0044] This concrete pipe pile scheme achieves the enhancement of overall stability through reasonable structural design. The synergistic effect of the support rods 5, support discs 4, inner lining pipe 2, and flange plates 3 enables the pipe pile to exhibit good performance when bearing various loads. In addition, this scheme has high adaptability. The number and distribution of the support rods 5 and support discs 4 can be adjusted according to different engineering requirements to meet the requirements under different load conditions.
