The present invention is suitable for the road construction technology field, in particular relates to a box culvert synchronous jacking system. The box culvert synchronous jacking system comprises a plurality of parallel jacking units, a plurality of electric throttle valves, a hydraulic pump and a measurement module. Each jacking unit comprises a plurality of parallel jacking pickaxes, one end of one jacking unit is connected with one end of one electric throttle valve, and the other end is connected with one end of the hydraulic pump, and the other end of the hydraulic pump is connected with the other ends of the electric throttle valves separately. The measurement module comprises a control unit used for adjusting the apertures of the electric throttle valves and a deviation detection unit used for detecting the jacking deviation of a box culvert, the deviation detection unit is connected with the control unit, and the control unit is connected with the electric throttle valves. By the above scheme, the measurement precision can be improved, and the jacking speed is accelerated.
