A composite pile of a prestressed high strength concrete(PHC) pile and an outer steel pipe attached concrete pile, a constructing method thereof, and an intrusion auxiliary pile used to the same are provided to determine a pile type, and to construct the pile effectively by integrating the PHC pile and the concrete pile using concrete. A composite pile has a lower part formed with a prestressed high strength concrete(PHC) pile(10) having a hollow(12), and an upper part formed with a concrete(21) and a steel beam hollow pipe(22). The steel beam hollow pipe is placed on the PHC pile and connected with the PHC pile integrally. Lower reinforcing bars(13) are inserted in the hollow of the PHC pile and installed with a floor plate(40) closing the hollow. An adhesion plate is closely contacted with the inner surface of the hollow of the PHC pile. Upper reinforcing bars(23) are inserted in the steel beam hollow pipe. The PHC pile and the concrete pile are integrated by pouring the concrete in the hollow of the PHC pile and the steel beam hollow pipe which are connected. Coupling plates(50) are integrally coupled with the reinforcing bars by combining the upper ends of the lower reinforcing bars with the lower ends of the upper reinforcing bars. |
