REPAIR METHOD OF CYLINDRICAL CONCRETE STRUCTURE
To provide a repair method of a cylindrical concrete structure that makes it possible to obtain the strength equal to or more than an initial strength with thickening within a range equal to or less than an initial thickness of a skeleton, and to perform repair work easily, meeting the need for urgency.SOLUTION: A repair method comprises steps of: removing the whole circumference of a concrete deteriorated layer; stretching and arranging a steel wire 3 over a healthy concrete surface 2 where the concrete deteriorated layers have been removed; applying or injecting resin repair material 5 thereon or thereto using a mold; and forming a repair layer 6 in which the steel wire 3 is buried.SELECTED DRAWING: Figure 2
【課題】躯体の初期厚を超えない範囲の増肉で、初期強度と同等以上の強度が得られ、さらには、補修作業を容易に行え緊急性に対応できる円筒形コンクリート構造物の補修方法を得る。【解決手段】コンクリートの劣化層を全周に渡って除去し、劣化層除去後の健全なコンクリート面２に、金属製ワイヤー３を張設し、その上から樹脂系補修材５を塗布あるいは型枠を用いて流し込んで、金属製ワイヤー３を埋設した補修層６を形成した。【選択図】図２
