The extent of any work , which are carried out in China , may hit the imagination of any human . The railway in China has been and remains the No. 1 transport for moving between cities. Passenger Railways . Network in China , probably already is the largest in the world and continues to steadily grow and get stronger .
In principle, for a country with such a high population density it would be difficult to come up with something else.
China plans to build s the most difficult in the world of mountain rail road . It will pass along the Qinghai-Tibet Plateau – one of the most geologically active zones of the Earth . The length of new railway roads is 1629 km, and the planned period of full completion of works – 2025 On first glance , not very long road, but the complexity of the terrain on which it will take place , is located on the transcendent level .
From the history of the issue : even in 2006 year in China passed the grand line to Lhasa, the most high-mountain in the world ( the line passes through the saddle-point point with a height of 5072 m). Its length is 1956 km. It connected Tibet and inner China to the main railway. Then the line was extended to Shigatse , this is another 253 km inland Tibet . But , the Chinese did not calm down on this , setting a new goal : to connect Tibet with indigenous China by the second latitudinal line from Sichuan . Future line received the name of the Sichuan-Tibet railway road Technically , in comparison with the construction of the Qinghai-Tibet railway roads, construction of Sichuan-Tibet railway road even with the lies it. “This is similar to the construction of the huge American slides between the most formidable and challenging valleys in the extreme plateau.”
Lin Sheqing , deputy chief engineer , explained. Ingenue ry should solve a lot of problems, such as a geographical error , a strong earthquake , a dense layer of rubble , strong geothermal barrier , a low supply of oxygen in the tunnel , and so on. D. In addition , the iron road of Sichuan-Tibet will re Seca river Yarlung Tsa ngpo 16 times, a total of 300 km of railway tunnels , or 74.6% of the entire railway .
In general , in the future railway road of Sichuan-Tibet will carry more than 48% of passengers , arriving in Tibet, and 41% of freight in Lhasa will also be transported by this railway road e. Meanwhile, it is not only facilitate transportation in the Tibetan Autonomous Prefecture of Garza , Prefecture Keturah Qamdo , Nyingchi and Lhok (Shannan),but and will benefit the trade of China with the countries of south Asia . In this scheme is seen both iron road on Tibet: from Qinghai ( green color , running ) and from Sichuan ( red , constructed ).
Sichuan-Tibet railway road will be the main backbone of the railway network of the West of China , linking Tibet with the more developed central and eastern regions. Highway will take the start in the city of Chengdu – the administrative center of the province of Sichuan, will pass through the Sichuan city of Ya’an and Kangding , a Tibetan town of Chamdo , where further stretch then through Linchzhi and lhoka to Lhasa – the administrative center of the Tibet autonomous region .
Plot road Ya’an – Nyinche , how to involve engineers , will be one of the most challenging railway projects in the world , because it passes through the southern portion of the Tibetan Plateau and crosses once more complex geological areas. The camping length of the project by 80% consists of tunnels and bridges , and the total drop height exceeds 16 thousand . meters , which is equivalent to the two heights of the highest mountain in the world Mount Everest .
The design speed of trains along it will be 160-200 km / h. After input of the railway roads in the operation time in the path from Chengdu to Lhasa from kratom from 48 hours to 13 hours and is projected to cost at 37 billion dollars Already Build a 1.56-kilometer tunnel Milin , Kotor first was laid on the 435-kilometer rail road of Sichuan-Tibet , which connects Lhasa with of the pinch in the south-eastern Tibet .
The tunnel is one of six 10-kilometer tunnels , which are based on the most difficult part of line 160 km / h. Gallery on Kroogi spruce Milin located at an altitude of about 1200 m from the surface and has an average altitude of 3100 m. The tunnel was considered ” the most difficult nut to crack ” for railway builders , and it was completed on April 7th . It was stated that its completion marked a huge progress in the implementation of the project of building a giant iron roads .
Due to its high altitude , cold climate , complex topography and inconvenient transportation, it is difficult to develop the economy of Tibet and western Sichuan . When the Qinghai Tibet Railway Road was completed, the economy of Tibet quickly grew, as she had a great help in promoting the development of industry , reduction of the cost of the incoming goods, more efficient use of natural resources and attracting growing numbers of tourists.
Still less , some people in the west of the province of Sichuan and Tibet continues to suffer from severe life , so that they rarely have the opportunity to communicate with the outside world and to develop its economy. Considers Xia, that the iron road of Sichuan-Tibet again will have a great value . Railway Station of Sichuan Tibet can be divided into three parts – Railway Road Chengdu Kangdin, rail road Kangdin of the pinch and railway road Lhasa of the pinch. It builds elstvo began with the two ends of the rail road.
Iron Road Chengdu Kangdin ( including iron road Chengdu Jaan and railway road Jaan Kanding) connects Chengdu and Kangding , passing through Jaan s. It began to build in 2014 year , and how will it be completed in 2018. year . This section extends up to 325 km, and the maximum speed of the train , going by railway road Chengdu Kanding , reaches 200 km / h.
Iron Road Kanding of the pinch – the most e linnaya, very tough and beautiful part of the media and three iron roads. Auge idaetsya, that , starting from 2018 the year it will be completed in 2030 year . Iron Road Kanding Nyinche stretches approximately 1,200 km with many tunnels and mos Tami. This iron road will you totally enchanting natural views.
Iron road Lasa Nyinche is common portion railway road Sichuan-Tibet , rail road Sichuan-Tibet (in step construction ) and railway road Gansu-Tibet (in step survey ) . The implementation of this project , launched in late 2014 the year , has been involved about 20 thousand . builders.
Iron Road , Sichuan-Tibet would allow to build the railway road connecting China, Nepal, India and other countries , that will contribute to the growth of the economy of the region with the help of convenient transport traffic.
