It suddenly rained heavily in Beijing. There is heavy rainfall, accompanied by strong winds. Where will the local rainwater flow?
Heavy rainfall is also one of the characteristics of this precipitation. For Beijing, the average rainfall in Beijing is 60 mm- 100 mm, and individual points can reach 200 mm-300 mm Generally speaking, it is very heavy rainfall. Convective weather is expected from afternoon to evening. It rained obviously and the whole process lasted for more than 30 hours. It is expected that the rainfall will be heavy.
The convection characteristics are obvious. In the process of rainfall, the hourly rain intensity accompanied by strong wind and lightning is also relatively large. Short-term strong winds can reach 7 to 9. There may be a thunderstorm. Heavy rainfall accompanied by strong winds will easily lead to risks such as water accumulation on urban roads, lodging of trees, and leakage of old houses, and the risks such as landslides, mudslides, collapses and flash floods in mountainous areas will also increase significantly. The public should pay attention to the nearby forecast and early warning information, try to reduce travel during the rainstorm, try to take public transport when going out, and stay away from high-risk mountainous areas and rivers. In particular, heavy rain has a great impact on traffic travel, and it is easy to be congested during the morning rush hour. Pay attention to traffic safety.
Beijing Subway: Stop decisively in case of emergency. In view of the extreme rainstorm weather, Beijing Rail Transit Operation Management Co., Ltd. said that when there is rainwater backflow at the entrance and exit of the station, facilities and equipment such as power supply escalators and elevators will be immediately closed, and the direction of gates will be adjusted to guide passengers away from the stagnant water area. Notify the maintenance dispatching center and drainage team, assist in drainage at the entrance and exit of the station, arrange security personnel to be on duty at the affected entrance and exit, and post notices.
For the station, focus on strengthening the control of the square in front of the station, the stepped ground, barrier-free ramps and other places that are prone to water accumulation. Sandbags shall be piled up in time at the entrances and exits, flood control baffles shall be laid, anti-skid mats shall be laid, anti-skid warning signs shall be erected, and cleaning personnel shall be arranged to reinforce the entrances and exits, passages and stations of the station. The platform is on duty to clean up the groundwater in time. Dredge stranded passengers at entrances and exits, issue disposable raincoats to passengers in need, and check whether there is water leakage around station equipment and facilities and ancillary structures.
In terms of trains, when visibility is insufficient in extreme weather, drivers should strictly limit the speed, pull at a lower position, and extend the braking distance in time to avoid "idling" and "slipping". Strengthen the lookout and stop decisively in case of endangering driving safety; According to the changes of rainfall and passenger flow, temporary visitors will be opened in time to adjust the transportation capacity during peak hours.
According to the "Emergency Notice on Doing a Good Job in Flood Control of Urban Rail Transit" recently issued by the Ministry of Transport, when there are emergencies such as flooding and backward flow, the subway in this city will strictly follow the requirements of the "Measures for the Organization and Management of Urban Rail Transit" and resolutely stop it if it does not have safe operating conditions.
