In the beautiful Qinghai-Tibet snow plateau, a 500 kV line project with the highest altitude, the highest altitude span and the most complicated natural conditions in Tibet, Tibet, and the Changdu Power Grid Network Project in Tibet is under construction. The power grid construction army gathered from all over the country crawled on the steep ridge and shuttled through the 72-turn, constantly breaking through the forbidden zone of life, challenging the limits of survival and fighting in the construction line. “The 19th tender section of Inner Mongolia Construction started in the north of Dewu Village in Nyingchi County, ending in Sejila Mountain, with a total length of 77.996 kilometers, a tower of 143 bases and an average altitude of 4,000 meters. It is the most difficult to mark. 1. "Introduction from Liu Zhiyong, project manager of Inner Mongolia Power Transmission and Distribution Co., Ltd." Along the steep mountain, the reporter followed the project staff and climbed to the construction site of the 19th section. The high altitude of more than 4,000 meters allows us to keep breathing. The countless Spider-Man, who was "hanging" on the high-voltage line, was shocked by us. The 19th section of the project was built by Inner Mongolia Transmission and Transformation Co., Ltd., 80% of the towers are in the virgin forest, the mountains are steep and the snow is everywhere along the line. Since the transportation vehicle cannot reach the site, the construction materials need to rely on the ropeway transportation, and the staff must walk up the mountain. "The effective working period here is only 6 months, the time is short, and the task is heavy. In order to increase the effective working time and save the physical strength of the mountain, we have to set up camp near the construction site." Liu Zhiyong said that due to the steep slope, the construction is difficult, plus High-altitude, hypoxia-induced altitude sickness, an iron tower that can only be built in five or six days under normal conditions, and it takes a month to use it. In such a tough environment, the Mongolian Railways Army has set a slogan of "guarantee quality, ensure safety" and "never build construction speed on the basis of environmental damage". In order to cut down a tree less, they changed the work that the original machine could do to manual operation. More than a year of intense construction has passed. At present, the foundation construction and tower construction of the 19th section of the construction project undertaken by Inner Mongolia Transmission and Distribution Co., Ltd. is completed. The project is expected to complete all construction tasks by the end of June. Crawling on the tower base, shuttle between the high-voltage lines... Recall that in 1996, since the Mongolian Electric Railway Army stepped out of Inner Mongolia to participate in the national West-East power transmission, the Inner Mongolia power transmission and transformation has been carrying on major national and international tasks, and it is now in Mongolia. Power projects were built in 13 countries including Brazil and Pakistan. "Tibet China Networking Project is a national key project. In order to meet the power demand for economic and social development in central Tibet, expand the coverage of power grids, promote the development of clean energy development in Tibet, and provide reliable power supply for the upgrading and upgrading of rural power grids. Give full play to the construction advantages of mountainous areas and high-altitude areas, and contribute their own strength." Liu Zhiyong said.
