Railway workers carry out grinding work on rails. Hangzhou Works Section
When the night calmed down the busy city, another sleepless night was about to start for the railway workers in the Hangzhou Works Section of the China Railway Shanghai Bureau Group Co., Ltd.
Every Spring Festival, “Homecoming†has become the theme of many urbanites. The Shanghai-Kunming high-speed railway within the jurisdiction of the Hangzhou Works Section is a large artery for passenger transportation in the east-west direction of East China. During the Spring Festival, the transportation pressure is particularly large. Due to the high volume of high-speed railways and high train density, the time left for railway workers to inspect maintenance equipment is from 0:00 am to 4:00 pm, and there is no train operation during this period every day. It is also known as the "skylight" period.
In the early morning of the 20th, at a working point near the Zhejiang Longyou Station of the Shanghai-Kunming high-speed railway, with the start of the "sunroof" blockade, the first-line workers in the Hangzhou Works Section opened the hot maintenance work. Xue Guangbin, director of the Jinhua high-speed line bridge workshop, told the reporter that the workshop plans to grind the rails of the Shanghai-Kunming high-speed rail Jinhuahang Changchang-Longyou Hangchangchang area tonight.
The so-called grinding is to "plastic" the rails. In order to perfectly match the wheels of the high-speed train and the rail surface, the workers need to correct the deformation of the rail section due to long-term friction. In addition, the grinding can also greatly improve the service life of the rail and ensure the continuous stability of the high-speed rail operation.
During the grinding process, the diamond drill bit and the rail track are polished and sparkle, which is particularly dazzling in the quiet night. Xue Guangbin carefully stared at the "big machine" every move. "Tonight's grinding operation is 13km. Compared with the traditional manual grinding, the use of large machine grinding not only improves the work efficiency, but also saves labor input, and the work quality is also artificial. Greatly improved."
In order to ensure the smooth operation of the passenger train safety during the Spring Festival period, and to provide passengers with a more comfortable and high-quality ride experience, such "deep night combat" has become the norm for first-line railway workers. In addition, in order to better complete the fine-tuning of the track of Shanghai-Kunming high-speed rail, the Hangzhou Works Section actively contacted the rail engineers of the Institute of Iron and Steel to conduct a sample survey on the profile of the rails of the Shanghai-Kunming high-speed rail line, formulate a grinding plan, optimize the rail profile and improve the track smoothness. And surveyed the status of the roads of 8 stations (lines) in Zhuji, Yiwu, Jinhua, Longyou, Zhangzhou and Jiangshan.
It is reported that in addition to completing the nighttime overtime work, the railway department also conducts emergency drills and post training to train common emergency projects such as rails or turnouts, orbital red belts, high-speed railways, etc. The passengers on the road cast a solid steel backing.
