【0015】 請求項1,2に係る発明によれば、電柱固定治具を用いてワイヤソー装置をPC電化柱に固定するので、短時間で迅速に、ワイヤソー装置を確実に固定することができる。また、ワイヤソー装置を鋼管ユニットに固定した状態でワイヤソーを回転駆動してPC鋼線を含め塑性ヒンジ部を切断するので、塑性ヒンジ部を安全かつ迅速に切断することができる。また、鋼管ユニットにワイヤソー装置を固定するので、鋼管ユニットのボルトと鉄筋の位置は不変のため、ワイヤソーのワイヤーで鉄筋を傷つけることなく切断することができる。

Abstract
To provide a construction method for earthquake-resistant reinforcement of utility poles that can safely and quickly cut plastic hinge parts, including PC steel wires. [Solution] In a construction method for earthquake-resistant reinforcement work on utility poles, in which a reinforcing steel pipe unit 10 is installed on the outside of an existing PC electrification pole EP to reinforce it, a wire saw device 5, which rotates and drives the wire saw to cut the target object, is fixed to the PC electrification pole EP using a pole fixing jig 1, and the wire saw is rotated by the wire saw device 5 to cut the plastic hinge portion, including the PC steel wire C1 of the PC electrification pole EP.
