ABSTRACT:
A novel piling comprises a tubular member containing a plurality of passages therein. The piling includes a first rod longitudinally placed within the inner diameter of the tubular member, with the first rod having a first plurality of blades attached thereon. The first plurality of blades will be aligned with the plurality of passages. The piling also includes a gripping member adapted for rotating the blades from the inner diameter of the tubular member to an extended position protruding through the passages. The gripping member consist of a first gripping surface formed on the first end of the first rod and a rod holder, operatively attached to the second end of the tubular member. The rod holder will contain the second end of the rod so that the first rod may be rotated by a turning of the first gripping surface. The novel piling may also include a second plurality of passages therein, along with a second rod longitudinally placed within the inner diameter of the tubular member and adjacent the first rod. The second rod will have a second plurality of blades attached thereon. The blades (and associated passages) of the first rod will be staggered relative to the blades (and associated passages) of the second rod so that the first and second rod cooperate with one another. A method of driving a piling into a ground surface is also disclosed.
