CONCRETE POLE CAPABLE OF BEING DIAGNOSED FOR FRACTURED STATE, OR THE LIKE

摘要

PROBLEM TO BE SOLVED: To provide a concrete pole that can be prevented from being broken by easily detecting its fracture, etc. SOLUTION: In this concrete pole for stringing overhead wires, lines for monitor from which the fractured state, etc., of the pole can be detected are longitudinally laid in the pole, and at the same time, the lead terminals of the lines are provided on the side face or in the upper part of the pole. The fractured state, etc., of the concrete pole is detected by electrically, optically, or acoustically inspecting the states of the lines for monitoring from the lead terminals, by using a sensor circuit or inspection device.
