With an investment of 50 billion yuan in the century's project, the Shenzhen-Zhongshan Corridor will be completed and opened to traffic in 2024
The Shenzhong Passage, with a grand project across the Lingding Ocean, is another feat of the mainland after the Hong Kong-Zhuhai-Macao Bridge. It will be completed and opened to traffic in 2024, when the distance between Shenzhen and Zhongshan will be shortened to 20 minutes, realizing rapid access between the core areas of the Guangdong-Hong Kong-Macao Greater Bay Area, which is of great significance to the development of the region.
The Shenzhen-Zhongshan Corridor is an important part of the national highway network G2518 across the Pearl River Estuary, and is also the core transportation hub project of the Guangdong-Hong Kong-Macao Greater Bay Area, with a total length of 24 kilometers, integrating "bridges, islands, tunnels and underwater interconnection". Among them, the cross-sea tunnel is about 6.8 kilometers long, including about 5 kilometers of immersed pipe section, and consists of 32 pipe sections and 1 final joint. The Shenzhong Tunnel is the world's longest and widest steel-shell concrete immersed tunnel, and its construction scale and technical difficulty are unprecedented.
During the construction process, the engineering team faced numerous challenges, including shipping, flood control, water conservancy, airport aviation height restrictions, marine environment, navigation safety and other factors. However, with their innovative spirit and high level of expertise, they gradually overcame these difficulties and successfully constructed 32 sections of the undersea tunnel.
In the construction of undersea tunnels, precision is a very crucial factor. In order to achieve this goal, the Shenzhen-Zhongshan Channel has developed the world's first immersed tube floating installation integrated ship "Yihang Jin'an 1". This ship has the largest installation capacity, the highest precision and the most efficient construction operation, which can meet the 80,000-ton immersed tube 50 kilometers of ultra-long-distance safe floating installation operations, greatly improving the construction efficiency.
In the deep and medium channel project, the installation accuracy of each pipe section is strictly controlled within 20 mm, and 15 pipe sections have reached the "millimeter" installation accuracy within 10 mm. This accuracy is achieved thanks to the excellent performance of the "Yihang Jin'an 1", an integrated ship, which has raised the world's centimeter-level standard for immersed tube installation to China's millimeter-level standard.
The success of the Shenzhen-Zhongshan Corridor project is not only the rise of a bridge, but also a magnificent leap forward in the field of cross-sea engineering construction in the mainland. This grand project, which connects the east and west banks of the Pearl River, not only demonstrates the mainland's outstanding strength in engineering construction, but also demonstrates the mainland's leading position in scientific and technological innovation and engineering technology.
The construction process of the Shenzhen-Zhongshan Corridor is a perfect combination of scientific and technological innovation and engineering technology. From design to construction, every link embodies the wisdom and sweat of countless scientific researchers and engineers. Guided by innovation and supported by science and technology, they have overcome one technical problem after another, and have written a new chapter for the mainland's engineering construction.
The construction of the Shenzhen-Zhongshan Corridor has not only injected new impetus into the development of the Guangdong-Hong Kong-Macao Greater Bay Area, but also promoted the economic exchanges and integrated development of the east and west banks of the Pearl River. The completion of this bridge will provide more convenient and efficient transportation conditions for the development of the Guangdong-Hong Kong-Macao Greater Bay Area, and promote the economic take-off of the Pearl River Delta region.
During the construction of the Shenzhen-Zhongshan Corridor, the concept of environmental protection runs throughout. The engineering team has adopted a series of environmental protection measures, such as reducing construction noise and controlling construction pollution, to reduce the impact on the surrounding environment. This people-oriented and green development concept is a distinctive feature of mainland engineering construction.
The construction of the Shenzhen-Zhongshan Corridor meets the requirements of sustainable development and provides a sustainable solution for future transportation development. The completion of this bridge will not only provide strong support for the development of the Guangdong-Hong Kong-Macao Greater Bay Area, but also set an example for the sustainable development of the mainland's engineering construction industry.
In short, the successful construction of the Shenzhen-Zhongshan Corridor is an important milestone in the construction of the mainland's cross-sea project, as well as an important embodiment of the mainland's scientific and technological innovation and engineering technology development. Let us praise the mainland's scientific and technological personnel and applaud their hard work and outstanding achievements! At the same time, we should also be proud of the mainland's engineering construction undertakings and the motherland's strength and prosperity!
