<p>Provided is a composite pile which is formed by integrating a PHC pile located in the bottom with a steel pipe pile located in the top. When a joint coupler for integrating and continuing the PHC pile and the steel pipe pile is installed, the seat on the top end of the PHC pile, which is used to anchor a tendon in the PHC pile of the prior art, is not required, and the PHC pile is integrated with the joint coupler through a bolt coupling instead of welding. Thereby, the present invention reduces material costs and improves workability, thereby improving cost-efficiency. In addition, the composite pile is securely integrated with the concrete foundation by installing reinforcing bars vertically embedded in the concrete foundation using a foundation connection assembly composed of multiple couplers installed on the top ends of the steel pipe piles, respectively.</p> |
