The waiting hall of Zhengzhou East Railway Station leaks rain like "water curtain cave". What's the situation at the scene?

According to Henan Daily, on the afternoon of July 20th, around 17, passengers stranded in Zhengzhou East Station photographed a scene of rain leakage in the waiting hall of Zhengzhou East Station. Like water curtain cave, the scene is very bad. There has been continuous heavy rainfall in Zhengzhou since yesterday. The staff evacuated the site personnel and carried out drainage work. Some trains passing through Zhengzhou were delayed, stopped or turned back. In order to cope with the passenger flow of returning and changing visas, Zhengzhou East Railway Station opened five windows for returning and changing visas in the first and eighth ticket offices.

It has rained for three days a year in Zhengzhou. Zhengzhou Meteorological Bureau made a data collation and summary of this rainstorm. From 0/6 o'clock to 0/7 o'clock in Zhengzhou on the 20th, the hourly rainfall reached 20 1.9mm, from 20: 00 to 20: 00 on the 9th to 20: 00 on the 20th, the single-day rainfall was 552.5mm, and from 20: 00 on June 7th to 20: 00 on the 20th, the three-day rainfall was 6/kloc.

The average annual rainfall in Zhengzhou is 640.8mm, which is equivalent to the three days of the previous year. From the climatological point of view, by fitting the distribution curve, the probability and return period of hourly precipitation and daily precipitation are all once in a thousand years. In climatology, the return period refers to the average interval of rainfall greater than or equal to a certain rainstorm intensity in the statistical period of rainfall records in a certain year, that is, the return period of rainstorm frequency.

Dozens of people were trapped in the stairway at Exit D of the subway station of the Convention and Exhibition Center. The water outside is almost flush with the stairs, and it pours down directly after crossing the stairs. The situation at the scene is very bad. Zhengzhou is now surrounded by knee-high floods. Now we only hope that the people of Zhengzhou can survive this disaster safely.

If someone is trapped near the Yellow River South Road on Shangding Road, you can search Dongjitang. There is water and food, and there are many beds available for free. However, if there are still people in the waiting room of Zhengzhou East Station who have not fled the scene or have been trapped inside, please keep your strength and wait for rescue. I hope everyone can come out alive!
