The present invention relates to a bridge lifting system, and a lifting method. To be more specific, the bridge lifting system comprises: a rectangular plate-shaped metal base placed on a lower part thereof in order to support a total weight thereof and the weight of a bridge to be lifted; a hydraulic device positioned on a center of an upper part surface of the base; and a pair of lower supporting boards which touch and are fixated to the upper part surface of the base, and installed in a left and right side of the hydraulic device having an increased sawtooth unit; and a bridge supporting board which includes an operating sawtooth unit and a tension tool. In addition, the lifting method using the bridge lifting system comprises: a preparation step of positioning the bridge lifting system between the lower part of a bridge and a bridge pier; a phased lifting step of lifting a bridge supporting board in phases, that is, as much as one sawtooth height of the increased sawtooth unit at a time by operating the hydraulic device; and a replacement step of replacing a bridge bearing after lifting the bridge supporting board to a target lifting height. As such, the bridge lifting system and the lifting method is able to provide stability, efficiency, and economic feasibility by automatically assisting support of a lifting device without any manual work by manpower during a lifting work.

    본 발명은 교량 인상 시스템 및 인상공법에 관한 것으로서, 상세하게는 상기 교량 인상 시스템은 하부에 위치하여 시스템의 전체 무게 및 인상대상이 되는 교량의 무게를 지탱하는 사각 판형 금속재질의 베이스; 상기 베이스의 상부 표면의 중앙부분에 위치하는 유압장치; 상기 베이스의 상부 표면에 접촉하여 고정되되 상기 유압장치 좌우에 한쌍으로 설치되며 증가톱니부를 가지는 하부지지대; 및 가동톱니부 및 텐션툴을 포함하는 교량지지대;로 구성되고, 상기 교량 인상 시스템을 이용한 인상공법은 교량하부와 교각 사이에 상기 교량 인상 시스템을 위치시키는 준비단계; 유압장치를 가동하여 교량지지대를 인상하되, 증가톱니부의 1개의 톱니 높이만큼씩 단계적으로 인상하는 단계적 인상 단계; 및 목표하는 인상높이까지 인상후에 교좌장치를 교체하는 교체 단계;를 포함하는 것으로서 교량 인상 시스템 및 이를 이용하는 인상공법에 관한 것이다.
