The minus 4℃ sprinkler is still "sprinkling"! The official response is coming →
With the advent of winter, temperatures in many areas have dropped below 0°C.
However, in some areas, sprinklers still spray water on the roads every day. When the weather is cold, water on the ground will easily freeze, causing inconvenience for citizens and frequent traffic accidents.
The pavement sprinkled at minus 4℃ turns into an "skating rink"
On the morning of November 29, on Jianhua West Road in the Central District of Zaozhuang City, Shandong, a sprinkler sprayed water and the road was frozen.
It can be seen in the video that pedestrians walked cautiously on the road, and even passing citizens fell down with people and electric vehicles.
It is reported that similar situations exist in many sections of Zaozhuang urban area.
Some citizens said that the
sprinklers
were still spraying water at minus
4 degrees Celsius
, and
more than ten people slipped
and
fell when they saw it alone .
If a motor vehicle passes by, it will be very dangerous.
This video also caused a heated discussion among netizens, saying:
This kind of operation is really incomprehensible.
The latest official response is here
The staff of the Central District Environmental Sanitation Bureau of Zaozhuang City, Shandong responded:
At present, the sprinkler department has been asked to stop sprinkling, and in the future, it will stop sprinkling below 2°C.
For the "sprinkling" in winter, various places have long had a coup
In fact, "sprinkling" in winter is unavoidable. There are four reasons:
The sprinkler can wash the dirt on the road to the side of the road, and it will be more convenient and safe for the staff to clean.
Sprinklers can water the trees in the green belt. Although the growth cycle of the trees in winter becomes slow, watering is still required.
In winter, the climate is dry and dust is easy to generate. Road dust control is one of the main contents of air pollution prevention and control. The use of water spraying is the most effective, quick and safe measure to curb road dust.
If it snows in winter, the snow will affect road traffic. Sprinkling water can accelerate the melting of snow and protect citizens' travel safety.
In response to this inevitable situation, relevant departments in some regions of the country have explored a set of work plans to adjust the operating time of the sprinkler trucks according to factors such as time, temperature, and climate each winter.
Urban Management Committee of Yichang City, Jiangxi: Adjust the cleaning time and scope
The road cleaning operation time changes from daytime to nighttime, avoiding the peak period of vehicle traffic, and covering all A and B grade roads in the urban area. The cleaning operation mode is "completely rinsed at night, patrol cleaning during the day, and circulating water to moisturize". In order to control dust pollution and haze weather, the main roads in the city will be sprinkled with water every 2 hours during the day to reduce dust.
Urban Management Department of Sanmenxia City, Henan Province: Sprinkle water during periods with higher temperatures
According to time, temperature, climate and other factors, choose to sprinkle water during periods of higher temperature every day; stagger the peak travel times on road sections with heavy traffic; adjust sprinklers to reduce water pressure and avoid pedestrians and vehicles.
Shaanxi Xi’an Urban Management Bureau, City Appearance and Environmental Sanitation Department: The temperature is below 3℃, no washing operation is allowed
The temperature is required to be below 3℃, and washing operation is prohibited.
Because the surface temperature often differs from the air temperature by 2℃~3℃, that is to say, the surface temperature has already dropped to the freezing point before the temperature reaches 0℃.
Therefore, the morning and evening temperature in Xi'an is around 1°C, and the city appearance department prohibits sprinkler operations.
