Reporter for China National Railway Groupthe companyIt was learned that on October 31, the “two tunnels and a bridge” of the Ya’an-Nyingchi section of the Sichuan-Tibet railway were started and the power supply was built.Project tenderThe results began to be published on the Beijing construction project transaction information network. This indicates that the construction of the Yalin section of the Sichuan-Tibet railway is about to enter the project implementation stage.

The length of the new main line is 1011 kilometers.

There are 26 seats on the line.station

The Sichuan-Tibet Railway runs from Chengdu City in Sichuan Province in the east to Lhasa City in Tibet Autonomous Region in the west. The line is 1,838 kilometers long. It is a fast railway connecting Sichuan and Tibet and the second national railway in Tibet.

The section from Ya’an to Linzhi, which is about to start, is in Sichuan Province and the Tibet Autonomous Region. The new line starts at Ya’an Station of the existing Chengdu-Ya’an Railway, passes through Ya’an City in Sichuan Province, Ganzi Tibetan Autonomous Prefecture, Changdu City and Nyingchi Autonomous Region from Tibet, and connects to the Linzhi station of the Lhasa-Nyingchi railway under construction. The line is a Class I national double track railway with a design speed of 120 to 200 kilometers per hour. The length of the newly built main line is 1011 kilometers and there are 26 stations on the entire line. Support the construction of 885 kilometers of temporary construction roads, 2,000 kilometers of power lines, as well as Chengdu and Linzhi operation guarantee bases, etc. Project estimateTotal inversionAbout 319.8 billion yuan.

According to the tender issued previouslyadThe “two tunnels and a bridge” and the power supply for the construction of the early start section of this tender are the early start section of the Yalin section of the Sichuan-Tibet railway, including the tunnel from Sejila Mountain to the Nyingchi Train Station, Kangding No. 2 Tunnel, Dadu River Bridge, and Related Supporting Rural Roads Construction and Reconstruction Power Supply Project in Initial Construction Section from Linzhi to Bomi and Ya’an to Xindu Bridge.

At the same time, special geological engineering studies and route plan were carried out to stabilize the route plan For long tunnels and large spans and tall piers in complex geological conditionsbridge, Developed an effective and reliableEngineering technologyMeasures to ensure the safety of construction and operation. Focus on the main scientific research projects of the Sichuan-Tibet railway and carry out important scientific and technological research; systematically summarize and comb domestic and foreign railways, highways, water conservancy and other similar engineering experiences, and form a series of technical summariesreportAnd the design and construction standards, and the deep involvement of academics and national experts, have provided strong technical support for planning and construction work.

This line bypasses many environmentally sensitive areas and comprehensively utilizes the slag discharged from the tunnels throughout the line in accordance with the principles of reduction, resource utilization and safety. Organized research and investigation on wildlife protection and formed an ecological protection plan, Route planning fully considers organic connection with airports and highways, and promotes the construction of a comprehensive transportation system;landComprehensive research of the development plan, play the leading role and benefits of the Sichuan-Tibet railway, and work hardto get betterThe production and living conditions of people along the line,Serviceeconomicsocietydevelopment of.
