Composite pile formed of interconnected rigid hollow tubes

A composite pile comprising two or more rigid hollow tubes interconnected together end-to-end by a pile connector, a boring head secured to a leading lower end of a lowermost one of said tubes, and a force transmitting member removably connectable to a top end of an uppermost one of said rigid hollow tubes to receive a driving force for driving each said two or more rigid hollow tubes into the soil, said pile connector having opposed axially aligned projecting pile connecting members extending from opposed parallel faces of a transverse impact transfer disc and extending a predetermined distance in adjacent open ends of said tubes to maintain said tubes in axial alignment with one another, said impact transfer disc being dimensioned to extend to an outer periphery of circumferential end edges of said rigid hollow tubes interconnected end-to-end and to receive said end edges in contact with said opposed parallel faces to transfer said driving force substantially uniformly between said end edges of said tubes interconnected together, said impact transfer disc being provided with one or more conduit connecting formations disposed exteriorly of an outer circumferential edge thereof whereby to retain a conduit adjacent said tubes, said one or more conduit connecting formations being integrally formed with said impact transfer disc and constituted by a pair of space-apart rigid curved clamping fingers defining a restrictive throat opening between opposed outer ends thereof leading to a retention cavity configured to receive said conduit in close fit therein.
