Stick to the political red line and professional bottom line and do our best to do a good job in railway flood prevention and relief work

Since the flood season this year, floods and waterlogging have occurred in many places in China. General Secretary Xi Jinping has continuously made important instructions on flood control and disaster relief work. Facing the severe situation of flood control, what challenges does the railway face? How can China National Railway Group Co., Ltd. focus on key points and implement accurate policies, scientifically and practically implement safety measures in flood season, and resolutely fight the hard battle of flood prevention and relief and transportation safety? In this regard, the reporter interviewed the flood control office of the State Railway Group.

Reporter: at present, the national flood control situation is very serious. What challenges will the railway, as the main transport artery, face? What deployment requirements does the State Railway Group have for railway flood prevention and relief work?

Flood control office: according to the forecast, in the main flood season of this year, China's climate situation is generally biased, extreme weather and climate events are more, precipitation is generally distributed in the north and south, and the middle is less. The disaster situation is generally complex and severe. Since this year's flood season, there has been frequent rainfall in South China and southwest China. Especially since June, continuous heavy rainfall has occurred in the eastern part of Southwest China and the middle and lower reaches of the Yangtze River. The rainfall along several lines of China Railway Bureau Group Co., Ltd., such as Wuhan, Shanghai, Nanchang, Guangzhou, Nanning, Chengdu and Kunming, has experienced a once-in-a-century rainfall. Facing the severe flood situation, the Party group of the State Railway Group conscientiously implemented the spirit of General Secretary Xi Jinping's important instructions, and promptly and decisively adopted a series of effective measures. Each railway bureau group company quickly implemented the deployment requirements of the Party group of the State Railway Group, based on the initiative of disaster prevention and risk avoidance, strictly implemented the safety driving measures in flood season, and organized carefully, strictly prevented and effectively responded. The vast number of cadres and staff are responsible for their work, guarding the soil and fulfilling their duties. They have been fighting in the front line of flood control and emergency rescue to ensure the safety of high-speed rail and passenger trains.

At present, the whole country has entered a critical period of "seven down and eight up" flood control. It is estimated that from July to August, compared with the same period in previous years, the precipitation in most parts of northern China will be 20-50% more than that in previous years, and the precipitation in western Inner Mongolia and some parts of western Gansu will be 50-80% more. In the early stage, the rainfall in the South China heavy rainfall area is still relatively large, and the coastal railway in South China will be affected by typhoon rainfall in the later stage. The task of flood control and flood fighting is extremely arduous. The Party group of the State Railway Group attaches great importance to the railway flood prevention and relief work, conscientiously implements the spirit of General Secretary Xi Jinping's important instructions, holds the whole railway teleconference, mobilizes and deploys the railway flood control and disaster relief and transportation safety work, and requires to carry forward the spirit and work style of continuous struggle, adhere to the people first and life first, so as to ensure the high-speed railway, passenger train routes and main transportation channels We should focus on safety and smooth flow, compact responsibilities, be brave in taking responsibility, implement accurate policies, scientifically and practically implement safety measures in flood season, resolutely fight the hard battle of flood prevention and relief and transportation safety, ensure the safety of high-speed railway and passenger trains, and ensure the safety and smooth flow of railway arteries, and make new contributions to maintaining the overall situation of economic and social development and ensuring the safety of people's lives and property.

Reporter: what specific measures has the State Railway Group taken in terms of highlighting key points, implementing accurate policies, scientifically and practically doing a good job in railway flood prevention and relief work? What key work has been done?

Flood control office: the State Railway Group firmly puts the safety of high-speed railway in flood season as the top priority, and requires the joint efforts of operation, construction, design, construction and supervision units to comprehensively sort out the weak links of flood control safety of high-speed railway, strengthen the inspection and inspection of key flood control sections and analysis of test data, timely and effectively deal with risks, so as to ensure the absolute safety of high-speed railway in flood season To ensure the safety and smoothness of busy trunk lines in flood season, it is necessary to rectify the hidden dangers of main busy trunk lines and main freight channels, implement rescue reserve and preparation work of personnel, equipment, materials, etc., to minimize the impact of water disaster on transportation order; take the rain situation as the order, focus on the water situation, implement effective flood control measures, and local meteorological, water conservancy, flood control emergency management, etc The Department should establish a contact mechanism to comprehensively grasp the rain situation, dynamically find out the water potential, and do a good job in preventing and avoiding danger ahead of time; strictly manage the construction safety in flood season, increase the control of key links such as construction plan, site protection and forbidden construction conditions, resolutely put an end to illegal and reckless action, ensure the safety and stability of construction in flood season, spare no effort to ensure the transportation of flood control and disaster relief materials and personnel, and strengthen the regulation To ensure that disaster relief materials can be transported as soon as they arrive.

At present, the south is about to usher in the typhoon rainfall period. Affected by the continuous heavy rainfall in the early stage, the water content of the mountain tends to be saturated, and the disaster prone period will enter. The northern part is about to enter the main rainy season. Compared with the south, the rainfall in the north is more likely to cause disasters. The State Railway Group further refined the flood control deployment and arrangement. The Ministry of industry and electricity issued a notice on making every effort to ensure the safety of flood control in flood season. The flood control office dynamically observed the clouds and chased the rain, followed up the rain and water conditions and disasters, and had a dynamic dialogue with relevant bureaus and groups every day to give timely key tips on flood control and flood fighting work, and guide and supervise the flood control work.

In the aspects of strengthening inspection, analysis and regulation to ensure the safety and control of high-speed railway in flood season: first, put forward the working goal of preventing collapse and putting collapse body on the road in flood season. Second, regarding the tunnel as the key point of flood control of high-speed railway, continue to organize the investigation and treatment of tunnel hidden dangers, and resolutely take blocking or speed limiting measures when problems are found. For the construction of cold joints, falling blocks, cavities and other key places, the Railway Bureau Group companies are required to establish management measures. In case of heavy rainfall, key patrol inspection shall be conducted, and personnel shall be assigned to guard when necessary. The third is to check the karst and water rich tunnels one by one. If there is high pressure and rich water, pressure relief holes should be added. In case of continuous heavy rainfall, "skylight" operation shall be checked and confirmed by rail operation vehicle. Fourth, the main risk points such as the front slope of high-speed railway tunnel entrance, long and long cutting section, hanging ditch under the wall of cutting section, transition section of road and bridge, and surrounding environment of high-speed railway shall be inspected periodically. If necessary, speed limit shall be used to enter the fence for inspection. Fifthly, all the key flood control sections of high-speed railway should be guarded by personnel, the cadres should be responsible for the protection, and the improvement measures should be studied and formulated. It is clear that in principle, there should be no long-term detention points for high-speed rail, and the flood control management of high-speed railway should be strictly prevented. Sixth, strengthen the analysis of the test data of the high-speed railway, especially the newly opened high-speed railway. In case of continuous heavy rainfall, arrange personnel to check continuously. Adhere to the analysis and tracking analysis of high-speed rail train shaking information. Organize the infrastructure testing center to conduct special analysis on the test data of high-speed railway in flood season.

In terms of highlighting key prevention and control and ensuring the safety and smooth flow of busy trunk lines in flood season, the first is to organize all railway bureaus and group companies to comprehensively sort out the key flood control locations of main busy trunk lines and freight channels, increase the number of watchmen, and provide sufficient guard, patrol and patrol forces in strong flood season. The second is to strengthen the dynamic investigation and treatment of hidden dangers of flood control, timely strengthen the slope protection and retaining wall with potential safety hazards, and timely organize the cleaning of various drainage ditches, water pipes, flood carrying bridges and culverts. It is required to take the initiative to expand the depth of investigation in the difficult and dangerous mountainous areas. Besides the dangerous work areas from the top of the mountain to the bottom of the river, it is necessary to investigate the potential risks all the year round. Besides, the investigation of gutters after rain should not be less than 100 meters. The third is to re check and re confirm the emergency materials, machines and tools, personnel and logistics support, so as to ensure the preparation is in place. Fourth, in case of rain blockade, the leaders of the public works Department of each railway bureau group company come to the stage, and the main leaders of the public works section go to the depot for command, and arrange the section leaders to organize emergency repair on site, so as to minimize the impact on transportation. Fifthly, the rainfall warning value should be reasonably determined in sections, and the passenger and freight should be classified to keep the freight train passing through to the maximum extent under the premise of ensuring safety. Sixth, according to the different characteristics of the north and the south, we should implement classified management and implement precise policies. To guide the Southern Railway Bureau Group companies to focus on flood control, post rain disaster and extreme heavy rainfall caused by typhoon, control the water situation and flood regulation along the line, strengthen patrol and intensive inspection on key sections with saturated soil and mountain water content; put an end to lax thinking and fluke mentality in Northern Railway bureaus and groups, and draw lessons from accidents Pay close attention to the accurate and detailed implementation of various measures in flood season, and highlight the prevention of key water disasters such as flooded lines, subgrade collapse, rockfall in some sections, and water scouring lines caused by short-term heavy rainfall.

Reporter: since July 15, several lines under the management of Shanghai, Wuhan, Xi'an, Nanchang, Chengdu and other Bureau Group companies have suffered from severe rainstorms. The cumulative number of water disasters and the interruption time of the whole road are significantly more than that of the same period last year. In view of this situation, what is the focus of the recent flood control work of the State Railway Group?

Flood control office: in order to ensure safety, the railway has taken a series of active measures to avoid danger, such as reducing the operation of railway passenger cars in mountainous areas and reducing the speed of passenger cars in some sections of ordinary railway. According to the deployment of the State Railway Group, the Ministry of transport, the Ministry of locomotive and vehicle, the Ministry of industry and electricity, and the dispatching center organized various railway bureaus and groups to adjust the operation of some passenger cars in Yingxia, Wangan, Taijiao, Jiaoliu, Chengkun, Baocheng and other railway sections. In the third quarter, speed limit measures were taken for 45 sections of 1194 km lines in 14 lines including Shanghai Kunming, Nankun and Xiangyu. In the main flood season, we took appropriate speed reduction measures for 298 sections of 37 ordinary speed railway lines with a total of 1871 km, so as to avoid mountain torrents, debris flow and geological disaster risks to the maximum extent.

At the same time, according to the requirements of the State Railway Group, the Railway Bureau Group companies continued to carry out the inspection and rectification of flood control risks. A total of 280000 person times of flood control inspection forces were dispatched to inspect 330000 bridges and culverts, 17000 tunnels and 180000 kilometers of subgrade. 24000 problems and diseases were found and 16000 repairs were completed. The places that have not been rectified temporarily were included in flood season inspection and patrol. 195 flood season guards and 2800 rainfall guards were arranged.

The main leaders and leaders in charge of the State Railway Group took the lead to set an example, went deep into the front line, inspected and guided the flood control work of the whole railway. Safety Supervision Bureau of State Railway Group and various professional departments set up flood control inspection team to supervise the implementation of flood control measures. Each railway bureau group company strengthens the cadre to lead the work, follows the shift to supervise. Flood control offices at all levels shall establish a dialogue system for flood control day, timely analyze sections affected by rainstorm, study and judge rainfall trend, sections and types of flood disasters that may occur, and supervise and control before rain, inspection in rain and emergency treatment in advance. Based on precision, clarity and practicality, the Ministry of industry and electricity of State Railway Group has formulated 25 safeguard measures and issued key tips to provide professional guidance for railway bureaus and groups from four aspects: ensuring the absolute safety of high-speed railway in flood season, ensuring the safety and smooth flow of busy trunk lines, strengthening the control of water regime analysis and implementing the management of North-South variance alienation. Organize all railway bureaus and groups to carry out emergency drills of high-speed railway safety information transmission in flood season, and open up the information transmission links among power supply, dispatching and maintenance. This paper popularizes the effective practice of Xi'an Bureau Group to effectively connect the site, dispatching and EMU by setting up flood prevention platform in train dispatching.

Reporter: according to the weather forecast, after July 20, the eastern part of China's main rain belt will be lifted to the north, and the north will enter the period of concentrated rainfall. In the east of Southwest China, there will still be more rain in the management of Chengdu and Wuhan Bureau Group companies. What is the focus of the next stage flood control work of the State Railway Group?

Flood control office: the State Railway Group will further refine measures, implement responsibilities, and resolutely ensure the safety of high-speed rail and passenger trains with wartime thinking, wartime standards and wartime conditions.

Further strengthen on-site inspection and supervision and dialogue guidance, go deep into the front line and command in front, and pay close attention to various flood control and disaster relief measures. Supervise the Railway Bureau Group companies to establish communication with local meteorological, water conservancy and emergency departments, master the rainfall and water regime along the line, especially the impact of environmental changes along the line on Hydrogeology and catchment area, and make targeted prevention in advance. Organize the railway bureaus and groups to carry out targeted dynamic investigation on hidden dangers of flood control according to the rain and water conditions within the management, strengthen the inspection and guard of key sections, and ensure the early detection, early disposal and early resolution of the insurance situation. According to the principle of "better to prepare than to use, when not available, no preparation" has been set up by various Railway Bureau Group companies, including 2300 vehicles of flood control rubble ballast, 2.1 million straw bags, 130000 wooden piles and 3800 excavators along the railway line, so as to prepare materials and equipment for flood prevention, emergency rescue and disaster rescue.

All relevant departments of the State Railway Group continue to guide the railway bureaus and groups to carry out drills to smooth the information transmission among the power, dispatching and EMUs. Organize to re check the emergency plan, materials and team preparation for flood control and disaster relief to ensure emergency preparedness. According to the principle of combining permanent and temporary, eliminating the root causes, leaving no future trouble, and paying attention to improving the flood resistance capacity of the section, the flood rescue and post disaster repair work should be done as a whole. For the water disasters occurred since this year, we should adhere to the analysis of each case, find out the causes and make up for the shortcomings. Strengthen the information analysis related to the safety of high-speed railway and passenger train, strictly implement the basic system and operation discipline, sink the cadres at all levels to the front line, command in front of them, grasp the safety with hard work, strictly grasp the strict management and strict assessment, resolutely put an end to the passenger train collision and collapse accidents, and firmly uphold the political red line and professional bottom line to ensure the safety of high-speed rail and passenger trains.
