At 16 o'clock on October 25, SANGRI County, Shannan City, Tibet, was as clear as the sky, with clouds rolling and clouds relaxing. On the Mingze super major bridge of Larin Railway on the Bank of Yarlung Zangbo River, TJ165 bridge erecting machine boomed, and a piece of 32 meter simply supported T-beam weighing 143 tons landed steadily on the pier On the pier and abutment, the four workers of the beam shifting team are ready to install the support fastener, align, pave dry hard mortar and level quickly The workers are skillful and cooperative. Every process, in their hands, is like making a perfect handicraft, which is not careless at all The total length of Mingze super major bridge is 3376m, with 103 piers and 2 abutments, of which 44 are located in the middle of the Yarlung Zangbo River. "This is the third hole beam erected today. It will take about 17 days to complete the track laying project of the bridge. Today, it is only 13 kilometers away from SANGRI station. " Nie Yongjun, the 37 year old leader of the laying team of Lalin railway project of the Third Engineering Co., Ltd. of China Railway Construction 11th bureau group, looks full of spirit and bright eyes on his dark face. "Since the track laying began in September 2018, we have overcome the difficulties of plateau hypoxia and complex construction conditions, ensuring that the construction progress is consistent with the construction period." China Railway Construction 11th Bureau Group has undertaken the tasks of track laying, partial fabrication and beam erecting for the main line of the railway with a total length of 399.61 km. Since the erection, the progress has been smooth. Nie Yongjun, who has rich experience in railway laying, is full of confidence in the construction of the railway. At present, he has completed the task of laying 106 kilometers of track, accounting for 26.5% of the total task, erecting 1133 beams, and 62.5% of the total task In the afternoon, the plateau is sunny, and the river flows slowly. On both sides of the north and the south, there are endless mountains. Between the two mountains, the track laying and beam erecting work is carried out in an orderly manner, and the operation process is strictly standardized. The continuous extension of the bridge is like a rainbow, crossing the river bank, and building a happy road for the Tibetan people. Nie Yongjun said: "this is the valley of southern Tibet. The river is wide and the wind is strong. It is facing severe sandstorm weather test. We will communicate with the meteorological department before operation. There are also advanced wind speed measuring equipment on the bridge erecting machine, which can judge the safe laying time more scientifically. " "The whole process of erecting one hole beam takes 3 hours. In this plateau area, we have set a record of erecting 7-hole beams in a day. " Liu Jun, Secretary of the Party Working Committee of the scaffolding project department, said, "every T-beam and every track array are transported here from Xierong track laying base by train. We have undertaken a total of 3628 beam making tasks, and now 2817 have been completed. " In the large beam making yard and track laying operation line in the scaffolding base of Caina Township, Qushui County, the workers are still working hard to produce "ammunition" for the front scaffolding "battlefield". In the long rail storage area of the base, the long rails with a total length of more than 200 kilometers are stacked together in a neat way, which is more than one person tall and can't be seen at a glance
