From the night of July 10th to 13th, there were regional heavy rain in central and northern Shaanxi and western parts, with heavy rainstorms. The scope of this heavy rainstorm is wide, strong, long, and strong. The land rainfall in northern Shaanxi and northern Guanzhong is close or super historic value, and the flood prevention situation is severe.
Land heavy rainfall can easily cause urban waterlogging
Causes serious threats to people's life safety
So what is urban waterlogging?
Urban waterlogging refers
Or continuous precipitation
More than urban drainage capacity
The phenomenon of stagnant stagnation in the city
Urban waterlogging occurred mainly in some areas with low coastal terrain, and inland cities now often occur.
The incidence of some specific locations in the city is higher
Drip bridge cave, subway, underground crossings, underground malls, underground malls, underground garages, etc. are all areas that are prone to waterlogging.
The "sick root" of the waterlogging
Affected by climate change, the annual extreme heavy rainfall frequency shows an upward trend
The intensity of rainfall and concentrated scope brings increasing challenges to the city
With the continuous expansion of the city scale, the urban waterlogging points are also increasing with the day
With the acceleration of domestic cities, the land that was originally covered with vegetation was replaced by asphalt roads and cement roads. Low -lying land used to store water became a house. Fully (such as underground garage, subway, etc.), various practices lead to a reduction in the accumulation and penetration of rainwater.
What should I do if I encounter urban waterlogging?
Pay attention to early warning and protect early protection
Pay attention to receiving heavy rain and stagnant warning information released by the meteorological and water affairs department;
After receiving the warning, the low -lying communities, shopping malls, garages, etc. should take protective measures in advance. You can use door panels and sandbags to build a dam.
Refuge to a high place
Fields are generally selected, high, more convenient, and good for hygiene conditions, such as the flat building top of high -rise buildings, schools and hospitals with high or firm buildings.
Stay away from electric equipment
Stay away from electricity usage facilities to avoid danger caused by facilities leakage. If you find that the high -voltage wire tower or the wire rod is dumped, if a broken wire is encountered in the stagnant water on the ground, it should be avoided quickly;
If you encounter waterlogging in the home, you should cut off the power and gas valve in time.
Pay attention to the flood prevention logo, not walking in the stagnant water, not close to the vortex
Do not walk on the road with stagnant water. Pay attention to the roadside flood safety warning signs. Try to get closer to the building as much as possible. Do not approach the places with vortexes to prevent dangerous areas such as deep wells and pits that are missing.
Precautions
When driving, do not risk driving the car to a place where there is water. Do not park the car to the low -lying place when you park to prevent the vehicle from entering the water;
Use low -end driving through the water accumulation, open the window;
If the vehicle accidentally gets off the water, do not start the engine;
In the event of danger, decisively abandoned the car to escape, and when he was trapped, he found a tool to break the car window.
Precautions for the bridge
When there is a waterlogging in the overpass, you should find the route of bypass in time. Do not walk blindly;
Vehicles that have entered the traffic bridge can be followed by traffic prompts. One is to drive in separate roads, and the other is to drive slowly at the auxiliary road with a high terrain;
Pedestrians should stay away from deep water, stay away from the vehicle, and choose a slow place to choose.
Don’t just travel to the water, not playing in the water
Do not make the water barefoot, do not let children play in the water. There are many bacteria and foreign bodies in the water. Foreign bodies break the skin will cause infection. Bacteria are easy to enter from the skin pores.
Pay attention to disease prevention after waterlogging
Avoid drinking water without boiling;
Food should be separated from raw and cooked, and heat before eating, and consume less foods that are prone to pathogenic bacteria as possible.
"Intellectuality" cities in cities are in the heart of flood control and drainage
After the Shaanxi Meteorological Observatory issued a warning of heavy rain, the Xi'an Digital Urban Management Supervision and Command Center will keep an eye on the Xi'an city flood flood prevention information system. The Xi'an urban waterlogging and flood prevention information system has marked 131 key prevention points in the city on the large -screen map. Each point coordinate position is clearly visible. On -site videos are transmitted in real time, and the attribute information of the responsible person is clear at a glance. Among them, some key points have a water level monitoring device, which can be collected in real time to report the accumulation of water on the site. As long as the monitoring water level is higher than the warning value, the system will immediately call the police to remind the relevant flood control personnel to deal with it in time.
The urban flood flood prevention information system connects data resources such as real -time meteorological, rainfall, meteorological cloud maps such as Xi'an City, as well as urban flood -related monitoring data. Combined with GIS maps, information can be basically achieved. Display on the diagrams, the staff can use the mobile phone app to achieve on -site command and scheduling.
The daily maintenance personnel will pass the drainage pipe network inspection dynamics uploaded by the system platform in real time. According to the database dynamic information update, it will always grasp the blockage, stasis, black and odorous water bodies, and lack of protective nets in the pipeline. Relying on the union perception of equipment and digital communication technology monitoring systems, once the monitored manhole covers have displaced, lack, damage, and rolling, etc., the system will automatically alarm in real time. According to the abnormal situation of the system prompts, the real -time push to the maintenance personnel in the background can ensure that the hidden dangers of various types of safety are effectively disposed of as soon as possible.
