China News Service, Wuxi, February 14 (Reporter Sun Quan) As we all know, when the weather is fine, the busy sprinkler trucks on the city roads can sprinkle water and dust to ensure the travel comfort of citizens.

So, is it superfluous to sprinkle water on the road when it rains?

Facing the doubts of some citizens, the Wuxi City Administration issued a document on the 14th to clarify their doubts.

　　The Wuxi urban management department said that the watering of the water trucks in rainy days is actually "borrowing the rain to make power" and "borrowing the rain to wash the road".

"The sprinkler operation that citizens see in rainy days is actually washing the dirt on the road, that is, using high-pressure water guns to wash the dirtier parts of the road while the ground is wet."

　　According to the relevant person in charge of Wuxi City Administration, during normal watering operations, it is difficult to remove dirt and stubborn stains such as dirt under the isolation fence, soil, mud, oil stains on the road, but after being soaked in rainwater, it will become soft and loose. The focus is greatly reduced, and the cleaning effect is better, which can be said to have a multiplier effect.

In case of moderate rain or heavy rain, there is enough scouring force, and there is no need for a sprinkler to "flush".

　　In addition, watering in rainy days is also based on two factors: safety and cleaning.

In rainy days, the dirt, stubborn stains, and accumulated mud on both sides of the road are soaked and brushed by rainwater and turn into mud, which affects traffic safety. At this time, the effect of cleaning the road surface is better than that on sunny days, the road surface is easier to clean, and it can also eliminate vehicles. Slip and pedestrian slip hazards.

　　"In rainy days, leaves, paper scraps and plastic bags are almost adhered to the road surface, making it extremely difficult to clean. Sanitation personnel have to spend a lot of effort to clean, which is not only unsatisfactory, but also has a certain impact on the safety of cleaning personnel and smooth traffic. Therefore, in rainy days, sprinklers are still used to wash and then clean, and the ultimate purpose is to better clean the road." The person in charge said.

　　Does it have to be sprinkled on sunny or rainy days?

Are there specific regulations on the working mode of the flush truck?

In this regard, the Wuxi urban management department explained that the Wuxi sanitation department will formulate different sprinkler operation plans according to seasons and weather conditions.

In summer and autumn, the air and road surface are dry, appropriately increase the frequency of watering and increase the humidity of the road surface; in winter, the operation time is concentrated on the high temperature at noon and afternoon every day, and night operations are cancelled, and the watering is stopped when the minimum temperature is below 3 °C Operation.

　　It is reported that because it is an outdoor open-air operation, weather factors have a greater impact on sanitation operations. In case of heavy rain, typhoon, or low temperature or freezing weather, the watering operation will be stopped in time.

Therefore, the operation time and operation methods of the sanitation department are not static.
