The present invention relates to a composite pile. Since a process of integrally forming a steel pipe and a PHC pile formed on the steel pipe is simplified by mounting a PC steel line mounting unit on an inner surface of the steel pipe, a process is reduced and a shearing key is formed in an inner surface of one end part of the steel pipe, thereby maintaining the steel pipe and the PHC pile to be rigidly combined. Therefore, the axial strength and bending strength of the pile are increased and the material cost of pile is reduced, thereby increasing economic efficiency.
본 발명은 강관 내면에 PC강선 정착부를 정착하여 강관과 그 상부에 형성되는 PHC 말뚝을 일체로 형성하는 과정이 간소화되어 작업공정을 단축시킴과 아울러 강관의 일단부 내면에 전단키를 형성하여 강관과 PHC 말뚝 간의 견고한 합성상태를 유지할 수 있도록 함으로써, 말뚝의 축방향강도와 휨강도는 커지고 재료비는 절감되어 경제성이 향상될 수 있는 합성말뚝에 관한 것이다.
