ABSTRACT:
A precast modular piling system of square-sectioned reinforced concrete sections of standard interchangable lengths are capable of being connected by a joint constituted by a steel jointing piece appearing at either end of the pile sections for purposes of enabling any length of pile to be constructed. Each jointing piece includes a shaped plate secured to the end of a pile section with a framing sleeve extending laterally from each plate. A recess extends inwardly from each corner of the jointing piece through the plate, adjacent parts of the framing sleeve and concrete of the pile section. The recesses are so dimensioned and shaped to receive an end of a substantially I-shaped locking pin which serves to join a driven pile section to a driving pile section upon placement of the respective facing plates in bearing relationship with one another. The abutting surfaces of the and the facing plates are planar to optimize surface-to-surface contact between these parts. The proper location of the locking pins during pile driving and subsequent thereto is maintained by distorting the plates with a hammer or appropriate tool at the shank portion of each recess to prevent the pins from retracting. The spacing between the locking pins and reinforcement bars appearing in the concrete sections at each corner thereof are held to an absolute minimum to assure proper performance of the joint in transmitting loads and stresses during the driving operation and demands of structural support.
