Recently, the winning bid for a key tunnel project with a total investment of 3.1 billion yuan was officially announced. With strong technical strength, rich construction experience, and reasonable scheme planning, China Railway Engineering Bureau successfully obtained the contracting right for the project, marking that this key infrastructure project related to regional transportation connectivity is about to enter the substantive construction stage.

The supporting construction of the project will also be planned synchronously, and management stations, emergency rescue facilities, drainage and ventilation systems will be set up in the entrance and exit areas of the tunnel to comprehensively ensure the safety of tunnel operation. In addition, it is expected to create thousands of job opportunities during the construction period, driving the development of related industries such as building materials supply and labor services, and injecting short-term vitality into the local economy; After long-term operation, the project will continue to release transportation dividends, promote industrial upgrading, urban expansion, and improvement of people's livelihoods along the route, which has important strategic significance for the high-quality development of the region.

At present, China Railway Engineering Bureau has started the preliminary preparation work of the project, accelerating the review of construction drawings, the entry of construction teams, and the allocation of mechanical equipment. It is expected to officially start construction in the near future. The planned construction period of the project is XX years. At that time, a safe, smooth, and green tunnel will span the mountains and become an important link in the regional transportation network, providing solid transportation support for economic and social development. In terms of technological innovation and quality control, China Railway Engineering Bureau will tailor a "smart construction site" management system for this project, which will achieve visual and digital supervision of the entire construction process through the deep application of IoT, big data, and BIM technology. For example, using geological radar to monitor the deformation of surrounding rock in real time, and automatically collecting construction data through intelligent devices to ensure that each process meets the design standards; At the same time, establish a three-level quality acceptance mechanism, from the entry of raw materials to the completion and delivery of the project, with layer by layer checks, and make every effort to create a "high-quality project" and a "century old project".

From the perspective of regional development pattern, the completion of this tunnel project will further improve the connection between the national backbone road network and the regional road network, and strengthen the radiating and driving effect of the central city on surrounding counties. It will not only shorten commuting time between cities along the route, but also promote the rapid flow of people, logistics, and capital, helping to form a "one hour economic circle" and building a convenient bridge for industrial transfer, cultural and tourism resource development, and urban-rural integration development along the route. Taking a certain characteristic agricultural product production area along the route as an example, after the tunnel is opened, the transportation time of products will be shortened by more than half, logistics costs will be significantly reduced, and the market competitiveness of regional agricultural products will be effectively enhanced.

In the face of complex geological problems and extreme weather impacts that may arise during the construction process, China Railway Engineering Bureau has developed a comprehensive emergency plan, established a professional emergency rescue team, and equipped advanced rescue equipment and materials. During the construction period, we will strengthen the linkage and cooperation with local government, meteorological, geological and other departments, assess risks and hidden dangers in real time, and ensure the safe and orderly progress of the project construction. At the same time, the construction party will actively fulfill its social responsibility, give priority to hiring local labor to participate in the project construction, carry out skill training, and help improve the employment ability of local people; And increase the protection and restoration of infrastructure such as roads and water conservancy along the construction line, reducing the impact of engineering construction on people's production and life.

Industry experts analyze that the construction of this tunnel project is not only a concrete manifestation of the country's acceleration of transportation infrastructure construction and expansion of effective investment, but also a key measure for promoting regional transportation integration development. As the project progresses, it will continue to release the "infrastructure dividend", providing strong support not only for stable growth and employment, but also laying a solid foundation for the long-term development of the region. In the future, this tunnel that runs through mountains and rivers will become a transportation hub connecting the north and south, as well as the east and west, witnessing a new chapter in the high-quality development of regional economy and society,Editor/Bian Wenjun
