REINFORCEMENT METHOD FOR UTILITY POLE
To provide a reinforcement method for a utility pole by filling and expanding an urethane foam resin including a fiber reinforcement material into a hollow part of a hollow concrete utility pole without using a spray gun.SOLUTION: In a reinforcement method for a utility pole, an urethane foam resin including a fiber reinforcement material is filled and expanded by mixing on airflow polyol and isocyanate to at least one of which the fiber reinforcement material is added and injecting a mixture of both into a hollow part of the utility pole.SELECTED DRAWING: Figure 1
【課題】 スプレーガンを用いることなく、中空状のコンクリート製電柱の中空部に繊維補強材を含む発泡ウレタン樹脂を充填して膨張させることによる電柱の補強方法を提供すること。【解決手段】 少なくとも一方に繊維補強材を添加したポリオールとイソシアネートを、空気流に乗せて混合し、両者の混合液を電柱の中空部に注入することで、繊維補強材を含む発泡ウレタン樹脂を充填して膨張させることによる。【選択図】 図１
