At this time, in order to ensure the normal use of roads and bridges, the cracks need to be repaired and reinforced.

[0003] A Chinese patent application (application number: CN202123331880.5) discloses a road bridge crack reinforcement structure, comprising a bridge body and a crack. The bridge body is provided with a reinforcement device at the location of the crack. The reinforcement device comprises a first fixing plate and a second fixing plate. The first fixing plate has a first fixing block vertically disposed on the top, and the first fixing block is provided with a threaded column. Two connecting plates are symmetrically disposed between the top of the first fixing plate and the second fixing plate.
