METHOD FOR REPAIRING CRACK IN UNDERWATER PART
PROBLEM TO BE SOLVED: To provide a method for repairing a crack in an underwater part, which can uniformly fill a crack in an underwater part with a filling material by a simple process.SOLUTION: In a method for repairing a crack in an underwater part of a concrete structure, a sheet material 11 made of an elastic material is fixed to a surface S of an underwater part with a crack CR so as to cover a crack; by injecting an underwater inseparable first filling material through an injection part of the sheet material, the first filling material 21 is filled in the crack leaving part 30 on a side of a deepest part of the crack; an underwater inseparable second filling material which is larger in fluidity than the first filling material is injected into the remaining part through an injection pipe 15 extending into the crack.SELECTED DRAWING: Figure 2
【課題】水中部のひび割れに充填材料を簡便な工程で満遍なく充填することができる水中部のひび割れ補修方法を提供する。【解決手段】このコンクリート構造物の水中部のひび割れ補修方法は、弾性材料からなるシート材１１をひび割れＣＲのある水中部の表面Ｓにひび割れを覆うように固定し、シート材の注入部を通して水中不分離性の第１の充填材料を注入することで、ひび割れ内に第１の充填材料２１がひび割れの最深部側の一部３０を残して充填され、第１の充填材料よりも流動性の大きい水中不分離性の第２の充填材料を、ひび割れ内に延在する注入管１５を通して残りの一部に注入する。【選択図】図２
