The longest "crossing" reflects the iron soul of road construction
At 11:30 on the 19th, with a blast, the geku railway, which was trudging among the mountains, completed the longest "crossing" in three years and six months. When the construction commander announced that the Arjin mountain tunnel was through, the cheers echoed in the tunnel at the junction of Xinjiang and Qinghai. (cctv.com) the completion of the
alchin tunnel is not only a celebration of the builders, but everyone will be excited by it. It's more convenient to explore the mysterious scenery of Qinghai and Xinjiang. It's more convenient for the residents of the two places to walk out of their hometown conveniently, and the communication between ethnic regions is closer. Indeed, geku railway is an important part of the central south passage of the three major railway channels of "linking the East with the west". As the third exit channel after the Lanzhou Xinjiang Railway and the Lanzhou Xinjiang high speed railway, it is of great strategic significance to further improve the land transport channel from the land to the border, Central Asia, Mediterranean and other regions in China. Under the prosperity, we should be grateful to the railway builders who have built all these, and we should learn from their "iron soul" of road construction A 6031 a 6031 hard-working spirit. The arjinshan tunnel is a first-class risk tunnel with extremely complex geological conditions. It has to cross 11 fault zones, including 9 water rich areas. The water output in the tunnel is relatively large, with the maximum daily water output of 27000 cubic meters, which is equivalent to the water storage of 10 standard swimming pools. Railway builders often work in "rain". Faced with the living conditions of "green plants can survive here for up to two months" and the multiple tests of plateau, cold, anoxia and water shortage, railway builders forge ahead step by step in the deep mountains. Ensure the construction quality with tenacious and dedicated spirit A 6031 a 6031 is brave to take on the fighting spirit. In the construction area of arjinshan tunnel, there are some unfavorable geology such as karst, swelling rock, high ground stress, fault fracture and water rich zone. Especially under the condition of expansive rock, it is equivalent to tunneling in "sponge". When the expansive rock absorbs the water vapor in the air and reaches the saturation concentration, it will burst and directly affect personal safety. In the face of the danger, the railway builders have not only gnawed the "hard bone" but also realized the connection earlier than the planned time
keep the dedication of loneliness. The longest "crossing" in 3 years and 6 months, working in the mountain with mobile phone signal only 5 meters on both sides of the National Road, no family warm companionship, no red and green lights, and no toasting. Some railway builders have a strong sense of mission and a high sense of responsibility of "people on the road, road in the heart", and they have no regrets to take up the responsibility of driving mountain workers in a powerful transportation country
this is an era of struggle, with the rise of the country, national confidence and social prosperity. When the heavy work makes you tired, think of someone struggling in a place with simple conditions, when you are afraid of the difficulties of work, think of someone challenging nature, when you complain about overtime, think of someone who has been dedicating for a long time in the mountains. On the way of pursuing the dream of a powerful country, "especially able to bear hardships, fight, endure, unite and dedicate", the railway people's actions provide a vivid example for the strivers, and once again vividly reflect the iron soul of road building!
