On the evening of February 20, there was snowfall in Beijing. The Beijing Municipal Environmental Sanitation Department started snow and ice removal work overnight to ensure the safety of the public.
The reporter of the main station reported that due to the influence of strong cold air, the snow will not melt in a short time after falling to the ground, so that the thickness of the snow quickly accumulates to about 7-8 cm within a few hours, which also brings great difficulty to the overnight snow removal and de-icing work.
Yang Jinliang, a second-level researcher of the Environmental Sanitation Department of the Beijing Municipal Urban Management Commission, said in an interview with reporters that the snowfall was uneven, showing the characteristics of large in the south and small in the north, and the south has reached the level of blizzard. The sanitation department requires that the motorized and non-motorized lanes of the main and secondary roads be cleaned before 6 a.m. on the 21st, and the roads are required to show their true colors.
A total of 630,000 people were on duty, and 6,370 snow and ice shoveling vehicles were dispatched to carry out the combined operation in accordance with the principle of mechanical snow clearing, manual snow clearing supplementation, and scientific use of snow melting agent.
