The Dongfeng 10-ton water sprinkling truck, as noted in the new regulations, also takes on the responsibility of dust suppression. With the arrival of autumn and summer, dry and low-rainfall weather, the city management department adjusts real-time based on weather conditions to increase the intensity of road washing and dust suppression to ensure air cleanliness. Dust suppression operations mainly take place during the day, and when water trucks are performing dust suppression, they should play warning music and avoid peak traffic hours to minimize impact on traffic and pedestrians. During operations, the nozzles should face downward, using high-pressure low-volume mist spraying; the mist's dust suppression height should not exceed 1 meter, and the width should not exceed 3.5 meters, achieving the effect of visible moisture without visible water flow on the road surface. High-pressure washing should not replace dust suppression operations. Except during rainy days and when the temperature is below 2°C, Hefei's main and secondary roads should be watered at least twice a day and washed at least once to ensure cleanliness and orderliness, revealing the road's true color. Prevent water from splashing onto pedestrians. (2) After the water in the tank is used up, the driver should promptly push the power take-off lever forward to disengage, stopping the water pump.
