All parts of Guangdong need to do a good job in preventing flooding and strong convection.
The Guangdong Provincial Meteorological Bureau reminded that the precipitation process affecting Guangdong will be from May 10 to 13. , has the characteristics of the strongest intensity, widest scope and longest duration this year. The risk of urban and rural waterlogging and geological disasters is extremely high, and it is necessary to pay close attention and do a good job in related defense work. It is recommended that all regions need to focus on preventing sustained heavy rainfall and the resulting urban and rural flooding, flash floods, mudslides, landslides and other disasters.
It is necessary to pay attention to the prevention of short-term strong winds, lightning and heavy precipitation in temporary structures for epidemic prevention and control. It is necessary to prevent the impact of strong convective weather on offshore operations, water transportation, island tourism, etc., and to take various safety measures. On the premise of ensuring the safety of the flood season, please seize the favorable opportunity and do a good job in scientific water storage in the reservoir. Heavy rainfall is coming in Guangdong, and many places in Guangzhou have strengthened their preparedness and response 3
According to the meteorological department's forecast, starting from May 10, Guangdong will have a round of large-scale heavy rains to heavy rains and local heavy rains. The reporter learned that in the face of heavy rains, Guangzhou Metro has fully launched flood control work according to the plan, deployed a number of safety emergency measures to ensure the safety of operating lines and citizens’ travel, and tried its best to build a dense “defense network” during the flood season and protect the subway. safety line".
Strengthen the investigation of hidden dangers, and personnel are on duty 24 hours a day.
According to reports, in order to prepare for relevant defenses, Guangzhou Metro has stepped up its efforts to encrypt nearly 4,000 line networks in advance. Comprehensive inspections have been carried out on key areas for flood control, 5 cross-river bridges, especially high-risk areas such as low-lying stations, section wind pavilions, entrances to entrances and exits, as well as the interfaces between new lines and existing operating lines, joint construction entrances, and manhole cover equipment and facilities. Conduct troubleshooting and rectify problems immediately if found.
Each station has organized a flood prevention and waterlogging drill in accordance with the "Flood Control Operation Map". All station staff are familiar with the three-dimensional structural diagram of the station, the distribution of flood control emergency supplies, the drainage and flood control situation within the subway area, and the surrounding river water levels. , runoff conditions and other key information.
At the same time, Guangzhou Metro has dispatched additional personnel to carry out 24-hour duty in key equipment rooms and key flood control areas since May 9, and will provide emergency rescue services to the original five full-time emergency rescue teams established by the construction general contractor. On the basis of the team and 142 part-time rescue teams composed of more than 3,000 people, we have established an operational emergency rescue team and 4 branch network professional emergency rescue teams, and have established operations in many key flood control areas such as Changqian, Yangji, Nangang, and Guanhu. Flood prevention assembly points are set up at stations.
When the corresponding early warning level is activated, the rescue team will immediately gather at the designated location to wait for orders.
Clarify the conditions for shutdown and start-up, and shut down operations if necessary
Based on the experience of flood control in previous years, Guangzhou Metro will respond to extreme events such as heavy rainfall exceeding the design intensity. Under the circumstances, emergency response measures such as train suspension, passenger evacuation, station closure, etc. will be simulated and reviewed, and entrance and exit closures, station closures, section suspensions, line suspensions, line network suspensions, etc. will be formulated according to the varying degrees of impact of extreme conditions. Five different levels of outage measures and corresponding start-up conditions are clarified.
When there are situations such as existing entrances and exits, safety evacuation water levels reaching the "station closure line", etc. that affect station operations, Guangzhou Metro will organize the closure of the affected stations in a timely manner; when external roads are flooded in large areas, resulting in water If the trains flow into the track area and affect the operation of the trains, Guangzhou Metro will promptly organize partial or even entire sections of the affected lines to be suspended.
At the same time, each subway station in Guangzhou Metro has a "Station Joint Prevention and Control Responsible Person List", which details the names and names of the seven-level flood control responsible persons in charge of the station, such as district, town, street, and subway group. Telephone for emergency use at the station.
In addition, we have established a good networking mechanism with emergency, water affairs, meteorological and other departments to make preparations for information communication and emergency support, timely predict the flood control risks of subway stations in the corresponding areas, and evaluate the situation as early as possible. Start the plan and jointly rescue.
When an emergency occurs, Guangzhou Metro will inform passengers of changes in subway driving organization through subway TV, station broadcasts, notices, official Weibo and other channels to facilitate adjustment of travel methods.
Replenish emergency supplies and increase flood prevention monitoring and early warning
In response to the upcoming heavy rains, Guangzhou Metro has purchased a new high-power hydraulic power station in recent years. , hydraulic submersible pumps and other flood control and rescue equipment are on standby at any time. At the same time, each station has also prepared flood control materials such as flood control sandbags, water-absorbent expansion bags, and flood control baffles. Key stations and depots are also equipped with water pumps, fire hoses, cable reels and other emergency supplies.
In addition, Guangzhou Metro is also 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, rain gauges and other equipment at key stations and flood control black spots, and will install relevant The output information is connected to the subway BAS system to realize functions such as rainfall level judgment, alarm and reminder, real-time and cumulative display, etc., effectively improving the ability of accurate early warning of flood control and empowering flood control with technology.
Guangzhou Metro reminds passengers that the road is slippery on rainy days, so passengers are advised to drive slowly and carefully to prevent slipping. When severe weather such as heavy rain or heavy rain occurs, the subway station will close the entrance and exit escalators in a timely manner according to the on-site conditions. At the same time, the station will provide citizens with services such as convenient umbrella rental and distribution of disposable raincoats, and strengthen guidance and services for passengers with reduced mobility. Passengers are requested to follow the instructions of on-site staff and enter and exit in an orderly manner.
