The present invention is a bridge lifting system and a method by complex control. When raising a bridge to replace a bridge bearing, a piston of a hydraulic jack is raised within a tolerance range through displacement control to raise the bridge. If the displacement of the hydraulic jack being lifted is outside the tolerance due to uneven lifting due to rigidity, vehicle traffic, etc., the bridge lifting system and method can make compensation through sub-raising through a sub-raising controller. The bridge lifting system of the present invention includes a plurality of hydraulic jacks, an oil tank, and a control part.
본 발명은 복합제어에 의한 교량인상시스템 및 방법으로써, 교량받침 교체를 위한 교량인상시, 변위제어를 통해 허용오차범위 내에서 유압잭의 피스톤을 상승시켜 교량을 인상하고, 강성에 의한 불균등인상, 차량통행 등의 원인으로 인해 인상 중인 유압잭의 변위가 허용오차를 벗어날 경우에 서브인상제어기를 통한 서브인상을 통해 보완할 수 있는, 복합제어에 의한 교량인상시스템 및 방법에 관한 것이다.
