ABSTRACT:
A method of repairing utility a pole having a section damaged by an accident or decay includes the steps of severing the utility pole above the location of the damage; removing the section of the utility pole including the damaged portion, and replacing the lower section of the utility pole with a steel stanchion having a platform thereon with a split socket disposed above the platform. The upper section of the utility pole is then laterally slid onto the platform through a window provided by opening the split socket upon removing one of two shells forming the split socket. The split socket is then closed by bolting one shell to the other. A space between the outer surface of the upper section of the utility pole and the inner surface of the split socket is then filled with urethane foam. The stanchion is made of a steel which forms a protective iron oxide coating, which coating is brown in color so as to match the brown color of the utility pole. In a preferred embodiment of the stanchion, the stanchion has a tubular lower portion. The split socket is made of two semicircular shells which are bolted both to one another and to the platform upon which the upper section of the utility pole rests.
