During spray maintenance, the pump body 14 transports water from the water tank 13 to the vertical tube 3 through the delivery pipe 15 and the double-ended pipe 16. The water flows through the spray holes set on the vertical tube 3, the first telescopic tube 4, the horizontal tube 7, and the second telescopic tube 8 to form a uniform water mist, which sprays the box girder in all directions. The device can move along the longitudinal direction of the box girder to achieve continuous maintenance without dead angles. The spray intensity can be adjusted by the control switch 20. The reinforcement plate 11 can effectively resist the water pressure reaction force during the spray operation to prevent structural deformation. The battery 19 can be charged and reused. The entire equipment is characterized by simple operation, flexible adjustment, and uniform maintenance, which can significantly improve the maintenance quality and construction efficiency of precast box girder concrete.
