INJECTION TOOL AND INJECTION METHOD FOR GROUTING MATERIAL
PROBLEM TO BE SOLVED: To provide an injection tool which can easily insert an injection tube into a grout injection hole, even in a limited space of a construction site where a reinforcement structure is complicated, especially a narrow space into which a worker is difficult to insert one's hand, and inject grouting material into a coupler, and to provide an injection method using the same.SOLUTION: In an injection tool, an injection tube 7 made of freely-bending soft material and whose tip end is reduced in diameter, is fitted to a reinforcement pipe 8 made of hard material and keeping a straight shape, so as to protrude from one end of the reinforcement pipe. Then, the tip end of the injection tube 7 is inserted into a grout injection hole, and grouting material is pressure-fed from the other end of the reinforcement pipe 8 and injected into a mechanical joint or anchoring fitting.SELECTED DRAWING: Figure 1
【課題】工事現場の鉄筋構造体が入り組んだ限られた空間、とりわけ作業者が手を差し入れることが困難な狭小な空間においても容易に注入用チューブをグラウト注入孔に挿入でき、グラウト材をカプラーの内部に注入できる注入器具、およびそれを用いた注入方法を提供する。【解決手段】自在に湾曲する軟質な素材からなり先端を縮径した注入用チューブ７を、硬質な素材からなり真っ直ぐな形状を保持する補強パイプ８の一端から突出するように装着し、注入用チューブ７の先端をグラウト注入孔に挿入し、補強パイプ８の他端から前記グラウト材を圧送して機械式継手または定着金物の内部に注入する。【選択図】図１
