ABSTRACT:
A solid pre-cast prestressed concrete foundation pile and associated installation components having a single prestressing strand located on the longitudinal center axis of the pile, reinforced in the ends only with helix shaped wire reinforcement. The prestressing strand extends beyond the concrete face on the end to present an attachment point for a connection device used to transmit forces from a structure foundation and to accommodate the utilization of a unique, reusable cushion block and, where necessary a, particular internal splice device to form a continuous pile composed of multiple segments.
The cushion block receives hammer blows applied to the top of the pile necessary to the driving (installation) process, affording protection to the pile top, the exposed strand and the internal splice device. The completed installation may include the optional attachment of the connection device (when required) after removal of the cushion block.
