CRACK REPAIR METHOD FOR UNDERWATER PART
PROBLEM TO BE SOLVED: To provide a crack repair method for an underwater part, which can prevent a filler from leaking by installing a simple formwork and easily grasp a filling state of the filler by visual inspection under water.SOLUTION: A crack repair method for an underwater part is a method to repair a crack on an underwater part of a concrete structure. A light permeable sheet material 11 made of elastic material is fixed on a surface S of an underwater part C having a crack CR so as to cover the crack. A filler is charged in the crack by injecting an underwater antiwashout plastic grout material as a filler 21 through injection parts 12a, 12c formed on the surface of the sheet material. Filling state of the filler is checked through the light permeable sheet material.SELECTED DRAWING: Figure 4
【課題】水中で簡易な型枠の設置で充填材料の漏出を防止でき、充填材料の充填状況を目視で容易に把握可能な水中部のひび割れ補修方法を提供する。【解決手段】この水中部のひび割れ補修方法は、コンクリート構造物の水中部にあるひび割れを補修する方法であって、弾性材料からなる光透過性のシート材１１を、ひび割れＣＲのある水中部Ｃの表面Ｓにひび割れを覆うように固定し、シート材の表面に形成された注入部１２ａ，１２ｃを通して水中不分離性の可塑性グラウト材を充填材料２１として注入することでひび割れ内に充填材料を充填し、充填材料の充填状態を光透過性のシート材を通して確認する。【選択図】図４
