In December, the northeast region ushered in the first snowfall after winter, with more than ten hours of snowfall and cold wind, challenging the operating limits of the Harbin High Speed ​​Rail. In order to ensure the safe operation of high-speed railway line equipment under severe cold, Shenyang Railway Bureau has continuously increased investment in science and technology, giving full play to the supporting role of high-tech equipment, and adding a safety barrier for the trains of the Harbin-Hedagon high-speed trains flying in the cold. Since the opening of the Harbin-High-speed Railway in December 2012, more than 130 trains have been flying on the Hada High-speed Railway every day. The Shenyang High-speed Railway Works Section of the Shenyang Railway Bureau is responsible for the maintenance of the 766-kilometer line from Fuyu North to Dalian. On December 5th, the reporter went to the safety production command center of the Shenyang High-speed Railway Works Section. The various display images on the display screen made the Qianli high-speed railway line unobstructed, and wrote the slogan of “safety first, scientific rigorous, quick response, strong commandâ€. Especially eye-catching. With a total length of 921 kilometers, the Harbin High-speed Railway is the world's first high-speed railway that passes through the alpine region. How to keep the high-speed rail in optimal operation under extremely cold conditions is also a worldwide problem. In order to ensure the safe operation of the Harbin high-speed railway, the Shenyang High-speed Railway Works Section has set up 146 monitoring units, 103 wind monitoring points, 39 rain monitoring points, 16 snow depth monitoring points and 40 lead intrusion limits along the Harbin High-speed Railway. Monitoring and 23 earthquake monitoring stations, these monitoring stations are woven into a three-dimensional cross-type safety net with monitoring and prevention everywhere. "Only by mastering the weak changes of the high-cold railway equipment, we can sum up and refine the most professional high-cold railway maintenance concept." Wang Xiaoming said. In order to reduce the impact of severe cold weather on the equipment of the line, the technical department of the section and the scientific research department of the Shenyang Railway Bureau selected a representative soil moisture meter along the Harbin high-speed railway to monitor different parts of the roadbed. The depth of water content, analysis of the variation of the water field in the subgrade, and the installation of 59 thermometers and subgrade monitoring devices along the high-speed rail to monitor the ground temperature changes and the longitudinal and lateral changes of the subgrade. In addition, this section also installed a wireless remote visual monitoring and early warning system for orbital position for Harbin High-speed Railway. It monitors the deformation of the track surface and the data of crawling caused by changes in the subgrade. It provides important parameters for the track stress change, which is the track and roadbed maintenance and Construction provides reference and warning data. Due to the high standard of high-speed rail operation and the difference in the standard of existing line operations, the inspection and acceptance of high-speed rail lines are completed by various precision instruments. Complex high-tech measuring equipment such as full-scale instruments and electronic theodolites have become the weapon of high-speed rail maintenance operations. These technical equipments show the superiority of traditional manual inspections in the maintenance and repair of high-speed rail lines in high-altitude areas, equipment fault alarms and processing, and real-time information collection. "Through the practice and exploration of the past two years, we have established a relatively complete set of operational safety organization measures to deal with severe cold and snow and ice weather, and accumulated rich experience for high-speed rail maintenance in the alpine region, and solved the high-speed rail maintenance in many high-cold areas. The world's problems have formed a scientific and rigorous production model." Qiao Lianjun, secretary of the Party Committee of the Shenyang High-speed Railway Works Section.
