BRIDGE REPLACEMENT METHOD
To provide a bridge replacement method for quickly performing replacement work of an existing slab bridge to minimize impact on existing traffic.SOLUTION: A bridge replacement method that removes a superstructure of an existing bridge and replaces the same with a new superstructure, comprises a new bearing installation step for providing a new bearing device between the superstructure and a substructure which are existing, a superstructure removal step for removing the existing superstructure located above the new bearing device, and a new superstructure installation step for providing a new superstructure on the removal site of the superstructure.SELECTED DRAWING: Figure 1
【課題】既設床版橋の架替え工事を迅速に行い、既存交通への影響を最小限に抑える。【解決手段】既設橋梁の上部工を撤去し、新設上部工に架替える橋梁の架替え工法であって、既設の前記上部工と下部工との間に、新設支承装置を設ける新設支承設置工程と、前記新設支承装置の上方に位置する既設の前記上部工を撤去する上部工撤去工程と、前記上部工の撤去跡に、新設上部工を設ける新設上部工設置工程と、を備えることを特徴とする。【選択図】図１
