ABSTRACT:
This invention relates to a concrete pile having a steel plate, of a semi-cylindrical shape,integrally fixed at the outer periphery thereof. The steel plate has a number of connectors protruding beyond the inner surface so as to thrust into concrete. The connectors are formed by performing the incomplete blanking of the steel plate. When the concrete pile is subjected to a concentrated load or a large bending moment, it can be reinforced by means of the steel plate. The operation of attaching a waling to the concrete pile can be also easily performed through means of the steel plate.
