CROSS-SECTION REPAIR METHOD OF CONCRETE STRUCTURE
PROBLEM TO BE SOLVED: To provide a cross-section repair method, easy even in replacing a sacrifice anode material, and taking into consideration long-term durability, by preventing macrocell corrosion of a reinforcement feared in construction of the cross-section repair method, by solving the problem possessed by a conventional technology.SOLUTION: In a cross section repair method of a reinforced concrete structure, a DC battery having an electric potential difference of 1.0-9.0 V and discharge capacity of 300-20000 mAh is connected to a conduction part of a metal wire and/or a lead wire for conducting a sacrifice anode material and a reinforcement, and a cathode is connected to the reinforcement, and an anode is connected to the sacrifice anode material, and the sacrifice anode material is installed so that a position of a construction joint interface side end part of an anode material inside of the sacrifice anode material, becomes on a construction joint interface between a cross-section repair material and a concrete hardened body, or a surface of the concrete hardened body within 30 cm from the construction joint interface.SELECTED DRAWING: Figure 1
【課題】従来技術の持つ課題を解消し、断面修復工法の施工の際に危惧される鉄筋のマクロセル腐食を防ぎ、かつ、犠牲陽極材の交換も容易で長期耐久性を考慮した断面修復工法を提供する。【解決手段】犠牲陽極材と鉄筋とを導通させる金属線および／またはリード線の導通部に、電位差１．０Ｖ以上９．０Ｖ以下で放電容量３００ｍＡｈ以上２００００ｍＡｈ以下の直流電池を、陰極を鉄筋に陽極を犠牲陽極材に接続し、かつ、犠牲陽極材の内部の陽極材の打継界面側端部の位置が、断面修復材とコンクリート硬化体との打継界面上、もしくは、打継界面から30cm以内のコンクリート硬化体の表面となるように犠牲陽極材を設置する鉄筋コンクリート構造物の断面修復工法、である。【選択図】図１
