The third road through the road through the Taklama Ganan Desert is opened to traffic

On June 30, the desert highway from Weili County, Xinjiang was officially opened to traffic. This desert road, which started construction in October 2017, has a total length of 334 kilometers. It is the third road that crosses the Takliman Desert after the Tarim Desert Highway and Ahe Highway. At this point, my country has built a desert highway over 1,200 kilometers in the Taklama -Ganan desert, which is known as the "sea of ​​death".

Three desert roads span the world's second largest migrant desert. How does road build roads in the "sea of ​​death"?

334 kilometers consumed for nearly 5 years. Where is the road to the desert?

Freshwater is extremely precious in the desert, but the roads cannot be separated from water.

Taklama Ganan Desert has an average annual precipitation of less than 100 mm, but the amount of evaporation is as high as 3,000 mm. High temperature drying makes the surface water extremely rare here. Although there are richer water resources here, the water quality is extremely poor and the salt content is high.

Drawing on the successful experience of the first two desert roads, the engineers adopted the dry pressure method on the desert section, that is, using the windy sand in the desert to directly compact the formation of the Shaki. Then spread a layer of geomantarie on Shaki, and then spread Gobi materials, gravel, etc. At the same time, the slopes wider than ordinary highways have greater side pressure to the roadbed. As a result, the loose sand has become a solid roadbed.

"We solve key technical problems in the wind -stricken sandy roads in the desert area. Such a process makes full use of the existing materials in the desert to reduce road repair costs a lot." Wang Yunfei, a desert highway project manager, said Essence

The difficulty of desert road building, Xinjiang Transportation Planning Survey and Design Research Institute, the person in charge of the project, Cheng Li is the most clear. The highway passed through the dense and tall sand mountains in the eastern part of the desert. A total of 32 Takahamishashan was tall and filled with 28 hill depression. The largest of which took nearly half a year.

In this harsh environment, the real challenge comes from the test facing workers' lives.

"Tak Raman" means "where you can't get out." One -third of this desert is the wind and sand day, and the sun is shining for a long time, and the surface temperature can even reach 70 degrees Celsius.

High temperature, allowing construction in the desert can only be "getting up early."

In order to protect the workers, the project department adjusts the schedule and selects when the temperature is low in the morning and evening to avoid the hottest period of the hottest in the desert. Even so, the high temperature in the desert allows workers to drink nearly 20 liters of water every day.

The danger of this desert construction is quite large. The dunes of wind and sand will move, and the changes in the location make it easy for people to lose their reference. In order to ensure the safety of workers, the construction site is equipped with a terminal with a Beidou positioning system. All kinds of prevention measures ensure that none of them are casualties in construction in such an extremely extreme environment.

Will Fengsha bury the road? Let the flowing sand dunes "quiet" down

The Taklama Gan Desert is the world's second largest flow desert. Under the action of wind, the dunes will "flow". This means that if you do not take any measures, you will be buried in just a strong windy road.

How to make the flowing dunes "quiet" and become another problem.

"The most feared in the desert is the wind sand. Sometimes the wind sand comes to stop the work, or even rework." Jing Wenyun, the chief engineer of the project, said, "Combined with previous construction experience, we adopt the" grass square+obstacles to the sand barrier '" Methods to establish a three -dimensional multi -level sand blocking system. "

The reeds growing in the wetland played a huge role in the arid desert and became "Gusana".

The reed stalks are dried and tied into the dunes, forming a square square of 1 meter long, distributed on both sides of the highway. This square -shaped lattice that is woven by reed stalks for sand fixation is called grass grid. Its layout is carried out at the same time with the construction of the highway. The widest unilateral side can reach 110 meters and the narrowest part is 60 meters.

When the slender reed straw is tightly arranged together and woven into a grass, it has the power to compete with the wind and sand. There is a grass square on the sand dune, and the sand is difficult to be blown.

The outside of the grass square is two obstacles, 10 meters apart. When the wind sand strikes, first pass the two outermost sand -blocking obstacles, and most of the sand with the wind speed and the wind sweeping the wind is also blocked. Then through the blocking of dozens of meters of grass squares, the wind sand is even more difficult to treat the road surface. Cause damage.

Why repair this road? "The Sea of ​​Death" contains infinite vitality

The county, located in Bayin Guo Leng Mongolia Autonomous Prefecture, Xinjiang, has long been inconvenient to traffic with the outside world for a long time. The opening of the desert highway shorten the journey of this "small town" and Korla 350 kilometers.

"This long -awaited road is finally opened!" Assen Turdi, who lives in the family, said, and at the end is the most remote county town in Bazhou. The girls in the field were unwilling to marry. It only takes 6 hours to go home from Korla home now, and it takes half of the time, and it is more convenient to travel. The opening of the highway also increased confidence in the company's investment along the route. There are more than 6,000 cattle farming in Xinjiang Xuanhara Animal Husbandry Development Co., Ltd., located in the Mochi County. Deputy General Manager Guo Chengli said.

In addition, the opening of this desert highway undoubtedly given a new choice for the desert of the self -driving tour. The desert highway has 307 kilometers deep into the hinterland of the desert. You can enjoy the unique landscape of deserts such as huge sand walls, sandy basins, and stretching sand dunes along the way. There are also 27 kilometers through the eutrier forest, wetland and vegetation coverage area.

This route through the area is a rich container for the Petroleum Geology of the Tarim Basin, which will provide strong support for the exploration, development, and transportation of oil and gas in the future, further promote the economic and social development of the southern Xinjiang region, and promote the development of advantageous resources along the line and economic and social development. It is of great significance.
