Abstract
This invention relates to a concrete pole having a reinforcing band and a cylindrical projection, protruding upward, at the outer periphery of the upper end, and a method of replacing the lower part of a wood pole with the said concrete pole. In order to replace the lower part of a wood pole, the lower part is first cut away from the upper part of the wood pole in use, and pulled out of the ground. Subsequently, the concrete pole is driven instead of the removed lower wood pole. Thereafter, the lower end of the upper wood pole is inserted into the cylindrical projection so as to be integrally connected with the concrete pole.
