This round of "the strongest rainfall" has an impact on Guangzhou, or it has reached the level of "the city's particularly serious rainstorm"

According to Guangzhou Climate and Agrometeorological Center's analysis of the rain conditions affecting Guangzhou from May 9, 10, it is predicted that there will be 200-300mm process rainfall in Guangzhou from May 10 to May 13, with local rainfall of 400-500mm and maximum hourly rainfall intensity of 80-/kloc-.

According to the historical meteorological records of Guangzhou, it is predicted that the precipitation in May10-May 13, 20 15, 201June 7-9, and June 5-9, 2020 will have similar impacts on Guangzhou. The above three rounds of precipitation, when the first two occurred, caused the underground facilities such as Guangzhou subway station and garage to be flooded or flooded, and the second two times all caused different degrees of geological disasters, which caused many waterlogging in the city and affected traffic.

It is estimated that the precipitation in Guangzhou will be affected from May 10 to May 13, 2022, or it will reach the level of "particularly severe rainstorm in the whole city". Guangzhou meteorological department reminds citizens and emergency rescue units to do a good job in advance.

It is predicted that the "strongest precipitation" will weaken after May 13.

Combined with the forecast of Guangdong Meteorological Observatory and Guangzhou Meteorological Observatory on May 9, showers turned to heavy rain and local heavy rain in Shaoguan, Qingyuan, Maoming, Heyuan and the north-central cities and counties of the Pearl River Delta in May 10; Other cities and counties in Guangdong are cloudy with (thunder) showers and partial heavy rain; Some cities and counties have (light) fog in the morning and evening.

All parts of Guangdong need to do a good job in flood control and strong convection prevention.

The Guangdong Meteorological Bureau reminded that the precipitation process affecting Guangdong from May 10 to May 13 has the characteristics of the strongest intensity, the widest range and the longest duration this year. The risk of waterlogging and geological disasters in urban and rural areas is extremely high, so we need to pay close attention to it and do a good job in related defense. It is suggested that all localities should focus on preventing persistent heavy precipitation and the disasters such as waterlogging, flash floods, mudslides and landslides in urban and rural areas.

Temporary structures for epidemic prevention and control should pay attention to prevent short-term strong winds, lightning and heavy precipitation. It is necessary to guard against the influence of strong convective weather on offshore operations, water traffic and island tourism. , and take various safety measures. On the premise of ensuring the safety in flood season, please seize the favorable opportunity to do a good job in scientific storage of reservoirs.

According to the forecast of the meteorological department, there will be a wide range of heavy rain to heavy rain in Guangdong in May 10. The reporter learned that in the face of heavy rain, Guangzhou Metro has started flood control and flood fighting in an all-round way according to the plan, deployed a number of safety emergency measures to ensure the safety of operating lines and citizens' travel, and made every effort to weave a "defense network" during the flood season and hold the "safety line" of the subway.

Strengthen the investigation of hidden dangers, and the personnel are on duty 24 hours a day.

According to reports, in order to prepare for relevant defense, Guangzhou Metro intensified encryption ahead of schedule, and conducted a comprehensive investigation of nearly 4,000 key flood control parts and five river-crossing bridges, especially low-lying stations, interval wind pavilions, entrance and exit sections, and new lines and high-risk areas such as existing operating line interfaces, joint construction ports, manhole cover equipment and facilities. When problems are found, they will be rectified immediately.

Each station organized a flood control and waterlogging prevention drill according to the flood control action map. All station staff are familiar with the three-dimensional structure of the station, the distribution of emergency materials for flood control, the drainage and flood control situation in the subway area, the water level of surrounding rivers, runoff and other key information.

At the same time, since May 9th, Guangzhou Metro has increased its personnel to be on duty 24 hours in key equipment rooms and key flood control areas. On the basis of five full-time emergency rescue teams established by the original general contractor and 142 part-time rescue teams composed of more than 3,000 people, 1 operating emergency rescue teams and four branch network professional emergency rescue teams have been established and deployed in Changchun, Yangji and Yangji respectively.

When the corresponding warning level is activated, the rescue team will immediately assemble at the designated place for standby.

Make clear the starting conditions of shutdown, and shut down if necessary.

On the basis of previous years' flood control experience, Guangzhou Metro simulated emergency measures such as train stop, passenger evacuation and station closure under extreme conditions such as exceeding the designed rainstorm intensity. According to the different degrees of extreme conditions, five different degrees of outage measures, such as entrance and exit closure, station closure, section outage, line outage and network outage, are formulated, and the corresponding startup conditions are defined.

When there are entrances and exits and the safe evacuation water level reaches the "station closure line", Guangzhou Metro will promptly organize the affected stations to close their stations; When the external roads are flooded in a large area, causing water to flow into the track area and affecting the train operation, Guangzhou Metro will promptly organize the suspension of some sections or even the whole line of the affected lines.

At the same time, all subway stations in Guangzhou Metro are equipped with the Table of Station Joint Prevention and Control Responsible Persons, in which the names and telephone numbers of flood control responsible persons in seven stations, such as District, Zhenjie and Metro Group, are registered in detail for emergency use.

In addition, we have established a good networking mechanism with emergency, water affairs, meteorology and other departments, made good preparations for information communication and emergency support, timely predicted the flood control risks of subway stations in the corresponding areas, judged the situation as early as possible, started plans and jointly rescued them. In case of emergency, Guangzhou Metro will inform passengers of the changes in subway traffic organization through subway TV, station broadcast, notice and official Weibo, so as to facilitate the adjustment of travel modes.

Enrich emergency supplies and strengthen flood control monitoring and early warning.

In view of shanghai dawn and Guangzhou Metro's newly purchased high-power hydropower stations, hydraulic submersible pumps and other flood control and emergency rescue equipment in recent years, they are on standby at any time. At the same time, all stations have prepared sandbags, water-absorbing expansion bags, flood control baffles and other flood control materials, and key stations are also equipped with emergency materials such as water pumps, fire hoses and cable reels.

In addition, Guangzhou Metro is actively exploring ways to enrich flood control monitoring and early warning, installing entrance and exit water level monitoring and alarm devices, interval water level monitoring and alarm devices and rain gauges at key stations and flood control black spots, and connecting relevant output information to subway BAS system to realize functions such as rainfall level judgment, alarm reminder, real-time and cumulative display, effectively improving the ability of accurate early warning of flood control, and empowering scientific and technological flood control.

Guangzhou Metro reminds that the road surface is slippery in rainy days, so please be careful and slow down to prevent slipping. When there is heavy rain, heavy rain and other bad weather, the subway station will close the escalator at the entrance and exit according to the site conditions. At the same time, the station will provide citizens with convenient umbrellas for rent and disposable raincoats, and strengthen guidance and services for passengers with mobility difficulties. Passengers are requested to follow the instructions of the on-site staff and enter and leave in an orderly manner.
