The sichuan-tibet railway starts from chengdu and reaches Lhasa via ya 'an, kangding and nyingchi, with a total investment of 270 billion yuan. When the line is fully operational, the running time of the chengcheng-lhasa railway is expected to be reduced from the current 36 hours to 13 hours. The sichuan-tibet railway project is expected to require 200 million tons of sand and gravel aggregate. According to experts, the sichuan-tibet railway is expected to produce 240 million square meters of hole slag, which will be mainly used to prepare gravel aggregate.

According to the national enterprise credit information publicity system, the sichuan-tibet railway co., ltd. was established on January 10, 2020 with a registered capital of 200 billion yuan. The registered place is located in nyingchi city, Tibet autonomous region. The official establishment of sichuan-tibet railway co., LTD. Will accelerate the construction of sichuan-tibet railway project.

sichuan-tibet railway co., LTD was formally established

The construction of sichuan-tibet railway is very difficult, among which the supply of sand aggregate is a key link. According to the views of the industry, the sichuan-tibet railway project is expected to require sand aggregate of up to 200 million tons. The terrain drop along the sichuan-tibet railway is huge, the highest elevation of the whole section is 4,400 meters, and the total elevation drop is more than 3,000 meters. Bridge and tunnel projects account for 81% of the total. & ndash; This means that the construction of the sichuan-tibet railway will produce a huge amount of hole slag, according to experts, the sichuan-tibet railway is expected to produce 240 million square hole slag, which will be mainly used for the preparation of gravel aggregate.

mechanism sand applied to sichuang railway project has technical reserve

According to the knowledge of China sand and stone association and China sand and stone network, on August 23, 2019, the Chinese academy of railway sciences conducted an experiment on the application of mechanical sand concrete in high-speed railway box girders. The static load test automatic control system of jszk-y type railway bridge was applied to load through ten loading points step by step, and the test was successfully loaded to 2.46 times the load. Jiang zhonggui, deputy chief engineer of the engineering management center, pointed out that the test was of great significance and provided technical reserves for the construction of the sichuan-tibet line.

Have & other; Century engineering ” The sichuan-tibet railway is a high-speed railway connecting chengdu, sichuan province, with Lhasa, Tibet. It consists of chengya railway (chengdu to ya 'an), yakang railway (ya 'an to kangding), kanglin railway (kangding - nyingchi), and lalin railway (Lhasa - nyingchi).

The chengya railway was opened to traffic on December 28, 2018, the lalin railway started construction in 2014, the yakang railway started construction in 2016, and the most complicated project, the kanglin railway, has not yet been started.

For the construction of the sichuan-tibet railway, wang group work conference in early January, 2020 will do a good job, and deepen the feasibility approval with optimized start early period of the construction organization plan, pushing the preliminary design and construction drawing design work, coordinate the relevant units and local governments to accelerate the construction of supporting facilities, fully implemented in accordance with the construction conditions.

The formal establishment of sichuan-tibet railway co.

the state attaches great importance to the construction of sichuan-tibet railway

In July 2018, premier li keqiang flew to the gongga airport in Lhasa and then went straight to the construction site of the lalin section of the sichuan-tibet railway in shannan city to inspect the exploration design and construction progress.

Li stressed that the lalin railway is an important section of the sichuan-tibet railway, which will become another major artery from the roof of the world to the mainland after the qinghai-tibet railway. It will not only bring Tibet closer to the mainland in terms of space and development, but also closer to each other psychologically. To accomplish this task, we have a great responsibility and a glorious mission. I hope you can build this railway into a high-quality project of quality and quantity, which can stand the test of history.

Li keqiang said that the sichuan-tibet railway is not only the aspiration of the Tibetan people, but also the aspiration of the whole country. At present, China's development is unbalanced, and infrastructure construction in the central and western regions lags behind. We need to speed up efforts to make up for this shortcoming, and gradually narrow the development gap between the eastern and western regions by expanding effective investment and speeding up infrastructure construction in the central and western regions.

Introduction to sichuan-tibet railway:

The sichuan-tibet railway is a high-speed railway in China that connects sichuan province with the Tibet autonomous region.

Sichuan-tibet railway is constructed by constructing new line and merging old line, and is constructed and operated in sections. Construction of the lalin and chengya sections began in December 2014.

The sichuan-tibet railway runs from chengdu, sichuan province, in the east, to Lhasa, Tibet autonomous region, in the west. The line is 1,838 km long, with a designed speed of 160 to 200 km/h.

The chengya section of the sichuan-tibet railway was put into operation on December 28, 2018. On December 1, 2019, the section of the sichuan-tibet railway from Lhasa to nyingchi was successfully paved to the yarlung zangbo river bridge in rongxiang, shannan city, Tibet.
