description The utility model relates to the technical field of environmental protection equipment. The utility model further discloses a dust falling and spraying device for highway bridge construction. The device comprises a base, a bracket and an air duct, a fan is arranged at the rear end of the air duct; a water tank used for supplying water to the air duct is arranged in the base, an acceleration area is arranged in the air duct, an air diffuser is arranged in the air duct relative to the acceleration area and is a cylinder, the diameter of the front end of the air diffuser is larger than that of the rear end of the air diffuser, and a water spraying device is arranged in the air duct relative to the front end of the air diffuser and comprises a water distribution pipe and a sprayer. The sectional area of the airflow channel in the acceleration area is smaller than that of the airflow channel at the fan; the area of the airflow passing face is reduced, the flowing speed of airflow can be increased, water sprayed ou
