A touching story about the road builders on the Qinghai-Tibet Plateau!

The first phase of the project is a Guanjiao tunnel with a length of 40 10 meter, an elevation of 3700 meters at the rail top and a water inflow of 2000 cubic meters day and night; Salt Lake Subgrade, 32km long, with 57,000 compacted sand piles, with total footage1.36m; The construction of the Bayinhe Bridge, the first reinforced concrete ballastless and pillowless beam bridge in China, and other special projects and new technological breakthroughs are not only pioneering works and miracles in the history of the development and construction of the Qinghai-Tibet Plateau, but also accumulated experience and laid a foundation for the second phase of the Qinghai-Tibet Railway. On May 1984, the Xining-Golmud section of the Qinghai-Tibet Railway was officially opened to traffic. More than 60,000 railway officers and soldiers and tens of thousands of road-building workers fought hard and bravely, built a "heavenly road" on the "roof of the world" and led the steel dragon to the Kunlun Mountain where it was born. At present, the central government has decided to start the construction of the second phase of the Qinghai-Tibet Railway from Golmud to Lhasa, which will fundamentally improve the backward traffic conditions on the Qinghai-Tibet Plateau and promote the economic development and social progress of the Qinghai-Tibet Plateau, and the century-old grand plan will become a reality. 1959, 1963 and 1974 entered Qinghai to build the Qinghai-Tibet railway, and 179 people died and 633 people were injured. The construction of the Golmud-Lhasa section of the Qinghai-Tibet Railway was suspended due to the special geographical and natural environment in Tibet and the technical problems of road construction such as plateau and frozen soil.
