The Bailey beam slides towards the two ends during pre-stress tensioning and is lifted as a whole, and pre-stress is also applied to a lower edge of the Bailey beam, thereby achieving the effects of having a inverted arch structure, closing cracks and reducing downward deflection. After tensioning is completed, sealing is performed by fixing a filler and a sealing steel plate (15) and by injecting a solidification body, such that the pre-stressed tendon (11) and the Bailey beam form a whole to be stressed together, thereby not only reducing a pre-stress loss, but also improving the durability of the pre-stressed tendon. The Bailey beam transmits a force based on a lever principle. Full use is made of the advantages of the Bailey beam and an external pre-stress, and by means of assembly-type construction, the Bailey beam is easy to assemble, has a short construction period and does not require traffic to be interrupted, and can be widely used in the field of the reinforcement of concrete structures.
