A bending relaxation method of the steel wire for the prestressed concrete girder enforcement is provided the girder is reinforced and conserved easily. A bending relaxation method of the steel wire for the prestressed concrete girder enforcement comprises as follows. A bending relax apparatus(100) having the from side to side expanded diameter is connected in the succession in which two girders(G) is connected. The succession comes under the end part of the steel wire planting a cutting(P) in which the steel wire for repair and reinforcement is inserted. |
