PROBLEM TO BE SOLVED: To surely and efficiently reinforce the entire body of a concrete utility pole. SOLUTION: In a concrete utility pole reinforcing method, a plurality of rods 22 are inserted from a side aperture 11, and suspended by aramid cords 22a (a rod insertion step). Next rod arrangement auxiliary tools 7 each having a plurality of penetration portions 72 are successively inserted from the side aperture 11, and suspended by aramid cords 7a (a tool insertion step). Then the rods 22 are suitably distributed to the penetration portions 72, and the former are penetrated into the latter (a rod penetration step). Further the side aperture 11 is blocked, and then a reinforcing agent 4b is charged from a top aperture 12 of the utility pole 1 (a reinforcement charging step). COPYRIGHT: (C)2006,JPO&NCIPI
