BRIDGE LIFTING APPARATUS USING ARCH SUPPORT BEAM FOR LIFTING JACK AND BRIDGE LIFTING METHOD THEREWITH
The present invention relates to a bridge lifting apparatus using an arch support beam for lifting a jack and a bridge lifting method using the same, wherein the bridge lifting apparatus is able to more stably support reaction force due to a lifted jack in an abutment and a pier having a lower bridge structure, and is able to quickly lift an upper bridge structure. The bridge lifting apparatus comprises: a plurality of pi-shaped vertical holding beams held to surround an upper portion of the lower bridge structure and installed in a transverse direction; a longitudinal tension material installed after having an upper end and a lower end of each of the pi-shaped vertical holding beams being stretched in a longitudinal direction, and fixedly installing the pi-shaped vertical holding beams in the lower bridge structure; and a lifted jack arch support beam formed in an arch shape beam extended in a transverse direction within an upper end inner side of the pi-shaped vertical holding beam.
교량하부구조인 교대, 교각에 보다 안정적으로 인상잭에 의한 반력을 지지할 수 있으면서도 신속하게 교량상부구조를 인상시킬 수 있는 인상잭 아치지지대를 이용한 교량인상장치 및 이를 이용한 교량인상방법에 관한 것으로서 상기 교량인상장치는 교량하부구조의 상부를 감싸도록 거치되어 횡방향으로 다수 설치된 ㅠ형 수직거치대; 상기 ㅠ형 수직거치대 각각의 상단과 하단을 종방향으로 긴장 후 정착되어 ㅠ형 수직거치대를 교량하부구조에 고정 설치되도록 하는 종방향 긴장재; 상기 ㅠ형 수직거치대 상단 내측 사이에 횡방향으로 연장된 아치형빔으로 형성된 인상잭 아치지지대를 포함하게 된다.
