A composite pile is comprised of two or more rigid hollow tubes interconnected together end-to-end by a pile connector. A boring head is secured to a leading lower end of a lowermost one of the tubes. A force transmitting member is removably connectable to a top end of an uppermost one of the rigid hollow tubes to receive a driving force for driving each of the two or more rigid hollow tubes into the ground. The pile connector has opposed axially aligned projecting pile connecting members extending from opposed parallel faces of a transverse impact transfer disc and extend a predetermined distance in adjacent open ends of the tubes to maintain the tubes in alignment with one another. The impact transfer disc is dimensioned to extend to an outer periphery of circumferential end edges of the rigid hollow tubes interconnected end-to-end and to receive the end edges in contact with the opposed parallel faces to transfer the driving force substantially uniformly between the end edges of the tubes interconnected together.
