How is the world's first desert railway "refined"?

Xinhua News Agency, Urumqi, June 16th. Question: How is the world's first desert railway "refined"?

Xinhua News Agency "Xinhua View Point" reporter

At 10:53 am on the 16th, a train with a full of passengers slowly sailed out and went east. From Hetian to Ruoqiang and Ruo Ruo Ranka officially opened to traffic.

The "holding hands" of the Ruo Railway and the Gaku Railway and the South Xinjiang Railway means that the Railway Railway Railway Railway is formally formed. This is also the world's first Ring desert railway line with a length of 2712 kilometers.

How is this railway "refined"? "Xinhua View Point" reporter conducted in -depth interviews.

How to design a plan?

He Ruo Railway was officially constructed at the end of 2018. Starting from Hetian City, Southern Xinjiang in the west, Ruoqian County, Payin Guo Leng Mongolia Autonomous Prefecture in the east, 825 kilometers in length and 120 kilometers per hour. Yu Tian and other 22 stations.

Before starting construction, it took more than 8 years of survey and design. The Taklama Gan Desert is China's largest desert and the world's second largest migrant desert. He Ru Ruo Railway crossing the flow desert through about three -quarters. How to prevent wind and sand and effectively solve the harm of wind and sand is a global railway construction problem.

"In the survey and design, we focus on the concept of ecological environmental protection." Said the China Railway First Survey and Design Institute and Ruo Railway Chief Designer Yang Baorong said that it not only takes into account the connection of the road network and the requirements of the economic development along the line The influence of the minimum and the best implementation of the entire railway investment and the implementation of the plan.

"Between Hetian and Ruoqiang, we have studied dozens of design solutions that have different directions, accumulating the research length of tens of thousands of kilometers, and finally determined the current 825 kilometers of line solutions." Yang Baorong said that trying to avoid serious in the area as much as possible. Winds and sand harm the location and ecological fragile and sensitive areas.

How to prevent wind sand?

Fengsha has always been a subject that cannot be avoided and unable to bypass.

"We are not afraid of cold or hot, we are afraid of wind and sand. We cannot be constructed at level 6 or above. Black Sand violence may be in white for a few days." In progress, while the team used a detailed storm diary to explore the innovative construction method to minimize the impact of wind and sand.

The builder adopted the method of "obstructing the sand and the grass", and established a multi -layer sand -blocking system combined with reeds, straws, and so on. There is an appropriate gap in each layer of obstruction to prevent the strong wind from forming a "blocking wall". Between the obstacles and the grass grid, plants that are easy to grow in the desert, red willows, and euphratica. In the future, these plants will form a permanent windproof sandwiches on both sides of the railway.

In the "Forbidden Area of ​​Life" Bacon Moring, it is also necessary to ensure a high survival rate of seedlings. The China Railway Bridge Bureau and the project chief engineer, Wu Jianglin, brought the technical personnel to form the experience and practice of "protection, take, time, and raising". Do full homework and work hard work in the aspects of cultivation, planting season, irrigation and maintenance. In order to get rid of the dilemma of planting saplings in the Gobi Beach, the survival rate of the seedlings is low, and the China Railway Bureau adopts a tree pit to change soil planting, that is, where the tree seedlings are planted, the soil will be changed, and the growth rate of saline -alkali will effectively improve the survival rate of plant.

During the construction day and night of more than 1,000, the builders built a total of nearly 50 million square meters of grass square along the Ruo Railway. Nearly 13 million shrubbings such as shuttle, red willows, sea buckthorn and other shrubs were planted, and the forest belt covered an area of ​​more than 110,000 mu. This 300 -kilometer "green corridor" has become a barrier to windproof sand.

In a particularly serious area of ​​wind and sand, and the Ruo Railway adopts a "bridge representing road" design plan, and builds 5 overham bridges with a total length of 49.7 kilometers, so that wind sand can pass through the bridge and reduce the impact on lines and train operations from the bridge. Essence

The Emulack Bridge is the only all -desert terrain construction bridge in the entire line, and it is also the longest crossed sand bridge in the entire line. Zhang Gang, deputy general manager of the Fourteen Company, who is responsible for the construction of the bridge, introduced that due to the desert terrain, the material transportation was extremely inconvenient. The single beams between the two bridge pier weighed 150 tons, and the car transportation could not be realized. The builder optimizes the construction plan and adopts the alternating construction of bridges and rail paving. The building materials are transported to the front line of construction through the laid railway rails, which not only improves construction efficiency and guarantees transportation safety.

In order to build a sand bridge, the builders also used the application technology of prefabricated concrete structure, which changed the practice of pouring pier pier on the spot in the past. Wang Bo, the chief engineer of the China Railway Beijing Engineering Bureau and the Ruo Railway Project, told reporters that the use of prefabricated bridge piers can not only solve the problem of desert lack of water, but also reduce the impact of wind sand on construction.

In the Taklama -Ganan desert renovation, builders must face various challenges such as sandstorms and construction materials, construction materials, and construction of water. Here, a little wind is the dust of the sky, wherever you go, covering the sky, the weather is as many as 90 days. From May to September each year, the maximum temperature at noon can reach 40 degrees Celsius, and the temperature of the desert surface at the construction site can reach 80 degrees Celsius.

"Thirty thousand steps, ten pounds of sweat, turning around with the kettle; deeper, shallow, stepping on the sand on the scene." This is the daily work of the builder.

How to help local development?

The Haruo Railway was opened to traffic, ending the history of Luo, Cele, Yu Tian, ​​Minfeng and other counties and Bayin Guo Leng Mongolia Autonomous Prefecture and the county and other places in Hetian are not in the history of the train. Hetian Zhihuo, Korla, and Urumqi are the fastest 11 hours, 26 minutes, 17 hours 50 minutes, and 24 hours and 23 minutes. At the same time, as a convenient logistics channel, and Ruo Ran will arrange 8 columns of cargo trains, cotton, walnuts, red dates, and minerals along the route can pass through the railway through the railway.

Buy Shibuyimu, who is on the starting train, is a representative of the Twelfth National People's Congress. His Pauli Township Bashiya Buy Village, where he is located, is a well -known pomegranate industry village. "Finally opened to traffic, excitement!" He said, the opening of this railway will make our pomegranate go further.

Hou Chao Ru 22 years ago, after graduating from Baoding College, Hebei, he taught at the end. She first took the train and then transferred to the car. She said: "Now the way to go home to the hometown has a new choice, the fellows are more common to travel, and it is easier to walk out of the desert."

"The new channel of the desert railway opens the flow of people and logistics, and the rich products and tourism scenery along the route will enter more people's vision to promote the economic prosperity of Xinjiang, especially the southern Xinjiang region." The Ya Site, Andyle Ancient City and other places brought more tourists to promote the development of the local tourism industry. (Reporter Liu Hongxia, Fan Xi, Hao Yu, Guan Qiaoqiao, Gu Yu)
