Why is the sanitation truck more busy on rainy days

First, in rainy days, the dirt, stubborn stains and mud remaining in the soil and pavement gaps on the road become soft and the adhesion is reduced after the rain. At this time, the use of high-pressure cleaning vehicles to wash the ground, the efficiency will be significantly improved than usual, to achieve the effect of twice the result with half the effort.

Second, the water flow pressure of the cleaning car is large, and it is easy to spray to passers-by. In order to avoid this situation, when working in sunny weather, the driver has to pay attention to the passers-by while cleaning, and it is easy to miss the unclean ground. On rainy days, there are fewer pedestrians on the road, and it is easier to let go and achieve better cleaning of the ground.

Finally, in the rainy day on the ground is easy to appear silt, if not washed off in time, after the solidification will bring a great burden to the cleaning work of sanitation workers, so clean up in time to better protect the city clean.
