The invention belongs to the technical field of tunnel invert arch construction and relates to a box girder through type self-propelled hydraulic invert trestle. The box girder through type self-propelled hydraulic invert trestle comprises a trestle body, a front approach bridge, a rear approach bridge and a movable supporting mechanism, the front approach bridge and the rear approach bridge are arranged at front and rear ends of the trestle body respectively, the trestle body comprises two box girders in bilateral symmetry and box crossbeams, and the box crossbeams are in longitudinal arrangement and connected with the box girders. The box girders serve as passage surfaces, and bridge decks cover the box girders. The movable supporting mechanism is arranged between the two box girders, an upper guide rail and a lower guide rail are parallelly arranged on the inner side wall of each box girder, the movable supporting mechanism moves along the lower guide rails, and correspondingly, the movable supporting mech
