Guide: on the Bank of the Zaga Zangbo River in the hinterland of Tanggula Mountain on the Qinghai Tibet Plateau, with an average altitude of 5068 meters, it is known as the forbidden zone of life. The employees of the construction engineering company of China Railway 18th bureau group, with the spirit of fearlessness, have written about the intellectualization of equipment at the highest railway station in the world The trend of digitalization is imperative. Write the theme of scientific progress, and show the era of challenging limits and moving forward bravely

on the Bank of the Zaga Zangbo River in the hinterland of Tanggula Mountain on the Qinghai Tibet Plateau, with an average altitude of 5068 meters, it is known as the forbidden zone of life. The staff of the construction engineering company of China Railway 18th bureau group, with the spirit of fearlessness, wrote the theme of Science and progress at the world's highest railway station, showing the style of the era of challenging limits and moving forward bravely

in March, spring is warm and flowers bloom in the mainland, and everything is full of vitality. Tanggula Mountain, the roof of the world, is frozen for thousands of miles, and the cold wind howls day and night

on March 28, 2003, when the project commander Li Bing, the Secretary of the Party Working Committee sun Lequn, and the deputy commander Liu Xiangrui led more than 260 employees to come here again, the plastic steel plate houses they had built in the past were destroyed by the ruthless hurricane, Mr. Paul Young, CEO of the quandenipei group, and the phosphorus magnesium plate houses were overturned by the roots. In the face of such a tragic scene, no one from the commander to ordinary workers was discouraged. On this deserted wasteland, they endured altitude reaction caused by severe hypoxia, suffered from splitting severe headache and breathed heavily. While setting up temporary tents, they organized forces to rebuild the camp. Without water, they went to the riverbed seven kilometers away to ice water; Hungry, eating instant noodles and dried mutton bought from Tibetans; At night, more than 10 people live in a tent, wrapped in clothes and quilts, snuggling up against the cold wind. Under such difficult environmental conditions, in only 40 days, rows of scattered dormitories and office buildings with green walls and red roofs rose from the hands of the workers, and the project department had its own home in Tanggula Mountain

Tanggula station, with a total length of 1.25 kilometers, covers an area of 77002 square meters, an average altitude of 5068 meters, and the highest point of 5068.63 meters. It is located in the open and gentle slope zone on the south side of Tanggula Mountain pass, belonging to the permafrost area

how to carry out the construction and make it fruitful? At the beginning of June, 2003, the engineering drawings of instruments and equipment worth nearly 100million yuan were in place. On the basis of organizing engineering and technical personnel to further investigate the site and conducting in-depth and detailed analysis and Research on the survey results, Li Bing, the youngest deputy general manager and project commander of the company, and other people decided decisively: "try to finish the foundation construction quickly and with high quality before the frozen soil melts not deep!"

first of all, they divided more than 260 people into three construction teams with Party and League members and technical cadres as the backbone. Then, the construction work was carried out rapidly mainly by mechanization. The workers who participated in the war put into construction with great enthusiasm, high morale and a serious and responsible attitude

before the construction of station subgrade, they first manually drained, rolled and compacted the base ground with natural drainage, so as to protect the permafrost layer of the base to the greatest extent. Then, the thickness of each layer is controlled within 30 cm for filling and rolling, and in different standards, although research units or manufacturers such as Belgium intercollegiate Electronic Research Center (IMEC) have invested in the research and development of high-rise buildings to lay two-way plastic geogrids for reinforcement. In order to ensure the quality of the fill, they prepared soil in the borrow area in advance for drying, and then transported it to the station for filling after the humidity meets the standard. An effective method is adopted to make the project under the baseline of station, yard and road start one section, form one section and become an excellent section

the railway station with the highest altitude in the world, its construction difficulty and requirements are quite high. Even the rubble filling of the station subgrade must be carried out under the premise of ensuring permanent ventilation and preventing silt and water from freezing. To achieve this goal, the cadres and workers who participated in the war did not spend less effort. First, we should strictly control the quality of raw materials. They equipped special screening equipment in the quarry and arranged special personnel to select rubble with a strength of not less than 30 MPa, which is clean, dust-free, rust free, crack free, and a particle size of 10 to 30 cm. Second, strictly control the base treatment and rubble dumping. On the basis of replacing and filling dry soil in low-lying areas and hot melt ponds and rolling to ensure flatness and compactness, bulldozers and excavators are used to dump rubble, and heavy vibratory rollers are used to roll repeatedly from both sides to the middle, so as to control the overall stability of rock filling. In the process of gravel paving, leveling and rolling, everyone, whether Party members, cadres or workers, was careful and careful, so that the leakage of gravel and sand was effectively controlled, and the ventilation effect of tens of thousands of square meters of station subgrade rubble reached the best state

up to now, the construction of Tanggula station has completed 80% of the total project, with a qualified rate of 100% and an excellent rate of more than 98%. The project department was rated as "advanced collective" by the superior leading organs, the Party Working Committee was rated as "advanced grass-roots party organization", and the Tanggulashan station commando of the project department was awarded the honorary title of "outstanding youth commando of Qinghai Tibet railway construction" by the national railway Youth League Committee and the Youth League Committee of the head office

Zaga Zangbu witnessed the construction process of the world's highest railway station, and sang for the glorious achievements of the builders in a unique way
