The present invention relates to a composite pile including a PHC pile and a steel pipe pile which has improved resistance to the horizontal force applied from the outside by coupling a reinforced bar and concrete to the inside of the steel pipe pile. The conventional composite pile has problems that costs is increase and coupling is not easily performed because the composite pile needs a separate adhering reinforcing member to couple a PHC pile and a steel pipe pile. To solve a problem, the composite pile formed by coupling a PHC pile and a steel pipe pile comprises: a PHC pile which has a through hole and is coupled to a lower side of the steel pipe pile; and a steel pipe pile which has a metal plate welded and coupled to a lower surface thereof and a plurality of vertical reinforcing bars and horizontal reinforcing bars inserted into the inside thereof and fixed and coupled by a second concrete layer. By making the vertical reinforcing bars and the horizontal reinforcing bars inserted into the inside of the steel pipe pile and coupled by the concrete layer, the composite pile including a PHC pile and a steel pipe pile can reduce manufacturing costs by reducing the thickness of the steel pipe pile and increase the strength of the steel pipe pile, thereby improving resistance to horizontal force applied from the outside. Also, the composite pile including a PHC pile and a steel pipe pile can reduce manufacturing costs and assembling costs because a separate load transferring member against a vertical shaft load applied to the steel pipe is not additionally required, and can more easily perform a manufacturing process by welding an outer circumferential surface to be simply and strongly coupled. |
