The Tianshan Mountains are located in the Xinjiang Autonomous Region, not only at high altitude, but also with steep terrain, but it is not easy to open a tunnel for it, but that isSo with the efforts of the engineering team, and in the end, it was a success.
So, how did it get through?What's the difficulty?
The Tianshan Shengli Tunnel has not only changed the traffic pattern between the two placesIt also injects into China's economic developmentA powerful momentum.
But at the same time, it has also encountered numerous difficulties and challenges. The Tianshan Mountains have a unique geographical location and extremely complex geological conditions, which are typical of volcanic landforms, which are important for tunnelsDesign and construction place extremely high demands.
The length of the tunnel reaches 221 km,It is a world-class super tunnel. Tunnels of this length require precise calculations and planning to ensure construction safety and quality.
Ventilation, lighting, and lighting inside the tunnelFire and safety facilities need to be carefully designedto meet the needs of long-term, large-scale transportation.
The tunnel needs to pass through multiple fault zones, which poses a serious threat to construction safety. The engineering team had to conduct a detailed geological survey and analysis of each faultto determine the best traversal scenario.
This requires not only advanced technical means, but also engineersExtensive experience and a high sense of responsibility.
The depth of the tunnel excavation and the distance from the road surface to the top of the hill are extremely challenging for tunnel construction and operation. The depth of the shaft means that ventilation and rescue are more difficult, and the depth of the tunnel is more stable for the tunnelDurability places higher demands.
High geostress and high intensity require that the tunnel design must take into account strong geological activity, and high environmental requirements require the entire tunnelMinimise environmental impact during construction.
The climatic conditions of cold and high altitude are for the construction personneland equipment put forward higher requirements.
There are many challenges at every stage of tunnel constructionBut these are all symbols of China's infrastructure technology development.
Although it is difficult, for the Chinese, we are confident that we can overcome all challenges. In the process, we have not only accumulated valuable experience, but also:It has cultivated a group of excellent engineering and technical personnel.
Construction of the Tien Shan Victory Tunnel,It's a true dawn. It illuminates the development prospects of western China, and also provides new ideas and directions for global tunnel construction.
Despite the challenges,But we firmly believe that through our wisdom and courage, will surely be able to build this tunnel into another great masterpiece in the history of human engineering.
In the face of so many dilemmas and challenges, the construction team did not choose to retreat, but bravely rose head-onDemonstrate their ingenuity and bravery.
In order to better accomplish this arduous task and speed up the construction progress, the construction team innovatively proposed a method called Three Holes + Four HolesA new way of building shafts.
This construction method is very innovativeThe extremely long tunnel is divided into three sectionsThen, two-way excavation starts from both ends of the tunnel, which greatly improves the construction efficiency.
Specifically, the left and right holes are usedThe traditional drill and blast method is used for construction, while the middle pilot tunnel is opened by a hard rock boring machine.
In addition, they deliberately dig holes,These holes are used in exceptional circumstancesThis design greatly improves the tunnel's ability to pass through and respond to emergencies.
In order to further overcome these difficulties, the construction team also developed a project calledThe world's first new injection method for Tianshan and ShengliHard rock boring machines.
The two devices are not only successfully combinedPress-cast concrete construction method and hard rock boring machinery, and also owns the Victory and Tianshan"These two loud and distinctive names.
These two machines are capable of working in extreme environments with their powerful performance, and the Tianshan is able to withstand a large number of mudslides and other unexpected situations in the mountains, while the Shengli isA record for the highest speed of a large-diameter tunnel boring machine was set, capable of digging 35 meters per day.
In order to cope with the more complex geological environment, the engineers also developed the first of the world's first hard rock vertical boring machines, which are equipped with special equipmentThe guidance system ensures precision during the tunnelling process.
The successful breakthrough of this new technology has obtained more than 20 patents and innovationsIt fully demonstrates the scientific and technological strength of the construction team.
The tunnel has greatly improved the efficiency and speed of transportation between the north and south of Xinjiang. It used to take more than seven hours to get from Urumqi to YuliNow it's just three hours.
This shortened time allows people and goods to be moreIt is convenient and efficient to circulate between the north and south of XinjiangIt has greatly promoted economic exchanges and ethnic exchanges between the north and south of Xinjiang.
For example, many specialties from southern Xinjiang can be shipped to northern Xinjiang at a faster speed, which is conducive to increasing the income of farmers in southern Xinjiang. At the same time, the labor and technology of northern Xinjiang can also passThe improved transportation conditions have led to the development of industries in southern Xinjiang.
This is conducive to narrowing the development gap between the north and south of Xinjiang.
The Tianshan Shengli Tunnel project is China's promotion with Central and West Asian countriesAn important transport corridor for cross-border interconnection by land.
It will not only facilitate cross-border exchanges between China and countries along the route, but also enhance Xinjiang's role as an international land portPromote the development of its logistics industry.
This will help accelerate the economic integration between China and the countries along the Belt and Road. This will make it easier for China's industrial products and technologies to be shipped to these countries, and it will also facilitateAgricultural products and resources from these countries are shipped to China.
This will allow the local population to benefit from a wider range of educationhealth care and other quality public services.
The high-quality medical resources in northern Xinjiang can benefit southern Xinjiang through improved transportation conditions, and the cultural needs of the people in southern Xinjiang can be better met through more convenient cultural exchanges. These will bePromote the overall improvement of the quality of life of local residents.
With frequent exchanges between people in the north and south, communication and understanding between different ethnic groups are also strengthening. This helps to promote mutual understanding and friendshipCreate a more united and harmonious society in Xinjiang.
The people of southern Xinjiang can also directly experience the advanced development achievements of northern Xinjiang, so as to understand the national support policiesEnhance the sense of national identity and social security.
In addition, the tunnel project will also strongly support the implementation of the Belt and Road Initiative and expand China's international route.
The Tianshan Shengli Tunnel Project is an important measure for China to expand its opening-up and deepen regional cooperationQuality development will have a profound impact.
The Tianshan Shengli Tunnel is not only the crystallization of the wisdom of the engineers, but also carries the hopes and expectations of the people of Xinjiang and the whole country for the future. Let's all applaud this epic project.
At the same time, I would also like to pay high tribute to the craftsmen and grassroots workers of the great country who have worked hard for it. The completion of the Tianshan Shengli Tunnel will undoubtedly be an important milestone in China's infrastructure history, but it will be much more than that.
