REPAIR METHOD AND INJECTION TOOL
To provide a repairing method capable of reducing the influence of water on resin and repairing a gap portion even when moisture is present in the gap portion.SOLUTION: The repairing method of the present embodiment is a repairing method of injecting resin into a gap portion 103 by a crack 102 of a concrete structure 100 using an injection tool 1, and includes steps S10 and S30. In the step S10, the injection tool 1 is adhered to a wall surface 101 of the concrete structure 100 with an epoxy type adhesive. In the step S30, the resin is injected into the gap portion 103 via the injection tool 1 at an injection pressure of 3.0 MPa. The injection tool 1 has an adhesion surface 11a, a main body part discharge port 132, a main body part supply port 131, and a flow path 13. The adhesion surface 11a is adhered to the wall surface 101. The flow path 13 connects the main body part discharge port 132 and the main body part supply port 131. When the area of the adhesion surface 11a is denoted as A and the cross-sectional area of the flow path 13 is denoted as B, A/B≥1.53 is satisfied.SELECTED DRAWING: Figure 6
【課題】空隙部に水分が存在する場合であっても、水が樹脂に与える影響を低減し空隙部の補修を行うことが可能な補修方法を提供する。【解決手段】本実施の形態の補修方法は、コンクリート構造物１００のひび割れ１０２による空隙部１０３に注入具を用いて樹脂を注入する補修方法であって、ステップＳ１０と、ステップＳ３０と、を備える。ステップＳ１０は、注入具１をエポキシ系接着剤によりコンクリート構造物１００の壁面１０１に貼り付ける。ステップＳ３０は、注入具１を介して空隙部１０３に3.0ＭＰａの注入圧で樹脂を注入する。注入具１は、貼付面１１ａと、本体部排出口１３２と、本体部供給口１３１と、流路１３と、を有する。貼付面１１ａは、壁面１０１に貼り付けられる。流路１３は、本体部排出口１３２と本体部供給口１３１を繋ぐ。貼付面１１ａの面積をＡとし、流路１３の断面積をＢとすると、Ａ／Ｂ≧1.53を満たす。【選択図】図６
