When artificial spraying maintenance is performed on the cast-in-place box girders, it is difficult for maintenance personnel to directly contact the bottom of the beam for maintenance operations due to the pier support underneath the cast-in-place box girders. If automatic spraying is used, it will also be affected by the height of the cast-in-place box girder and the stability of the spray pipe layout cannot be guaranteed.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content
