Interconnectable hollow steel pipe for constructing force driven piles and the method of forming the pile

An interconnectable hollow metal pipe for the construction of force driven piles, said hollow metal pipe being comprised by:

• an elongated hollow metal pipe of predetermined length having a pipe connector, said pipe connector having a fitment section for connection in one of opposed hollow transverse ends of said hollow metal pipe for securing said pipe connector in said one of said opposed transverse ends, the other of said opposed hollow transverse ends being a hollow transverse end, said pipe connector having a protruding pipe connecting section dimensioned for sliding fit in said other hollow transverse end of another of said hollow metal pipe, said pipe connector having securement means forming at least two spaced-apart weld cavities with an outer surface of said hollow metal pipe, said weld cavities each configured to have formed therein a weld not exceeding said outer surface of said hollow metal pipe to provide an unobstructed pile outer surface comprised of two or more of said hollow metal pipes interconnected end-to-end by at least one of said pipe connectors said pipe connector also having a torque transmitting disc immovably connected to said other of said opposed hollow transverse ends adjacent an outer surface of said hollow metal pipe, said torque transmitting disc having a shaped through bore formed therein for receiving engagement with said protruding pipe connecting section of a further one of said hollow metal pipe whereupon a rotational force is transmitted thereto.
