(Be sure to watch till the end) Knowledge Extension>>> Why do sprinkler trucks still work on rainy days? Sprinklers working on rainy days are not a waste of water resources, nor are they redundant, but there are very reasonable reasons: Ensure traffic safety: The dirt on the road turns into mud after being soaked by rain, which makes vehicles slip easily. Sprinklers can flush the road surface at this time to eliminate traffic safety hazards. Improve flushing efficiency: Rainwater makes the dirt on the ground soft and reduces its adhesion. In this way, the sprinkler truck can efficiently flush the dirt without spraying too much water. Reduce the workload of sanitation workers: With the flushing of sprinkler trucks, sanitation workers do not have to clean in the rain. Moreover, because the garbage on the ground is washed to the sides of the road by sprinkler trucks, the cleaning work of sanitation workers becomes easier after the weather clears up. |
