China New Network Taiyuan, May 1 (Ren Lina) On the 1st, the 653-kilometer Daqin railway contact line was cut off, all trains were suspended, 9,800 construction workers, 45 large-scale maintenance machinery, and 81 small machines entered the railway line. On the May 1st International Labor Day, the Chinese West-East Coal Transportation Channel started a concentrated medical examination in the spring. This is the most mechanized construction since the Daqin Railway initiated the centralized repair mode.

  The Daqin Railway runs from Datong in Shanxi Province to Qinhuangdao Island in Hebei Province in the east, with a total length of 653 kilometers. The Group, the top ten iron and steel companies and tens of thousands of industrial and mining enterprises, as well as the transportation of coal for production and living in more than a dozen provinces, municipalities and autonomous regions, are important energy channels. Every spring, in order to restore the quality of the line equipment after high-intensity transportation during the Spring Festival, Daqin Railway will carry out a concentrated repair construction.

  Affected by the new coronary pneumonia epidemic this year, the concentrated repair of the Daqin Railway has been delayed by about a month from the previous year, ending from May 1 to May 30. During this period, it will be shut down for 3 hours from 7:00 to 10:00 every day, and large construction machinery and construction teams will be concentrated to carry out large-scale operations, from aerial power supply contact nets, ground rail facilities to underground cables, and three-dimensional maintenance. Doing more than a dozen construction operations such as switch ballast replacement, rail replacement, and tunnel cleaning.

  In order to adapt to the requirements of epidemic prevention and control, and improve the quality and efficiency of construction, in this year's Daqin Railway's concentrated repair construction, tamping machines, cleaning vehicles and other large road maintenance machinery of three bureau companies in Beijing, Jinan and Zhengzhou have also moved to thousands of miles. The Daqin Line helped to carry out related construction operations and at the same time used 81 small excavators for the first time. The small excavator is equipped with slope rakes, ballast buckets and plow plows, which are designed by the employees themselves, and can greatly reduce the amount of manual work when changing lines and cleaning screens.

  Zhang Feifei, secretary of the party branch of Datong Engineering Department ’s Huaying Line Workshop, said that on May 1st, they exchanged stone ballast for two sets of turnouts. Originally, 300 people were needed. After adding 8 small machines, only 100 people were needed, which increased labor. The efficiency has reduced the drawbacks of manual work standards that are not easy to be unified, and has also reduced the intensity of personnel, ensuring the safety of epidemic prevention and control. According to statistics, with the use of a large number of mechanical equipment, this year's Daqin line has been concentrated in construction, saving more than 1,100 people compared to last year.

  At the same time, in order to ensure the correctness of construction and transportation, Taiyuan Bureau Group has precisely formulated the construction plan and transportation plan, accurate each construction operation to the minute, and launched a special transportation plan during construction, striving to stabilize the traffic volume, put The losses affected by the epidemic have been recovered and played an active role in ensuring energy security and stabilizing the supply chain of the industrial chain.

  It is understood that on the same day, another large railway channel in Shanxi Province, the Beitongpu Railway also started intensive repair work. (Finish)
