After seven years of hard work, the Shenzhong Corridor, a magnificent super cross-sea cluster project, has finally unveiled the veil of mystery. It is not only a perfect integration of bridges, islands, tunnels and underwater interconnection, but also a symbol of Chinese wisdom and tenacity. It is like a giant dragon, shuttling in the choppy sea, from east to west, adding another beautiful scenery to the prosperity of the Guangdong-Hong Kong-Macao Greater Bay Area.
Zhang Changliang, deputy director of the Shenzhen-Zhongshan Corridor Management Center, unveiled the mystery of the world's largest cross-sea project for us in an exclusive interview with China News Service's "East-West Question".
Embroidery on the bottom of the sea, 32 "kisses of the deep sea" are completed at the millimeter level. If the tunnel is "the hidden dragon in the abyss", then the bridge is "the flying dragon in the sky".
In order to ensure the navigation capacity of 300,000 tons of Lingding Channel, the Shenzhen-Zhongshan Channel adopted the design scheme of the East Tunnel and West Bridge. "There is an undersea tunnel to the east and a bridge to the west, so to let the two hold hands, we must first build an artificial island in the sea." Zhang Changliang, deputy director of the Shenzhen-Zhongshan Channel Management Center, introduced.
57 steel cylinders, each 28 meters in diameter, 35-40 meters high, weighing up to 650 tons; The construction team has developed the core technology of steel cylinder foundation pretreatment, which "grinds tofu" on the foundation of uneven and uneven construction sea area to reduce the strength of hard soil formations, and the self-developed 12-hammer linkage hammer group with the same frequency vibration and sinking has successfully driven a giant steel cylinder into the submarine rock formation accurately and firmly.
The opening of the Shenzhen-Zhongshan Corridor will undoubtedly leave a strong mark on the traffic pattern of the Pearl River Estuary. How will it reshape the traffic vein of this busy water? Behind this, what kind of scientific and technological mysteries and ingenuity are hidden?
He gave an in-depth interpretation of the construction wisdom behind the project and its significance for the further connectivity of the Guangdong-Hong Kong-Macao Greater Bay Area. At the same time, he also discussed China's outstanding achievements and continuous innovation spirit in the construction of infrastructure projects such as cross-sea and cross-river corridors.
China News Service reporter Chen Chuhong recorded this moment with his camera, allowing us to witness the epic leap of China's cross-sea passage project.
The Shenzhen-Zhongshan Corridor is a 24-kilometer-long bridge connecting Shenzhen and Zhongshan in Guangdong Province, China, and is a world-class "bridge, island, tunnel and underground interconnection" cluster project.
The construction of the Shenzhen-Zhongshan Corridor is of great significance for promoting the economic development and regional integration of the Pearl River Delta region. It will greatly shorten the travel time between Shenzhen and Zhongshan and strengthen the connection and cooperation between the two places. At the same time, it will further improve the transportation network in the Pearl River Delta region and improve the transportation efficiency of the region.
The construction of the Shenzhen-Zhongshan Corridor faces many technical challenges. One of the most challenging was how to construct a 6.8-kilometer-long undersea tunnel in a complex marine environment. In order to solve this problem, the engineering team adopted a series of advanced technologies and processes, such as immersed tunnel technology, underwater robot technology, etc.
The construction of the Shenzhen-Zhongshan Corridor also pays attention to environmental protection. The engineering team has taken a series of measures to reduce the impact on the marine ecological environment, such as establishing marine ecological reserves and carrying out marine ecological monitoring.
The construction of the Shenzhen-Zhongshan Corridor will inject new vitality into the development of the Pearl River Delta region. It will promote the coordinated development of the regional economy, strengthen the ties and cooperation between the Pearl River Delta region and other regions, and promote the sustainable development of China's economy.
It is expected that the Shenzhen-Zhongshan Corridor will be completed and opened to traffic in 2024. At that time, it will become another important transportation hub in the Pearl River Delta region, providing a more convenient passage for people's travel and cargo transportation.
