Beneath our feet, the \u56ed\u5cad2\u6865 stands as a testament to modern engineering. This bridge is part of the larger Shenzhen-Zhongshan Link. It connects Shenzhen, Guangzhou, and Zhongshan. Imagine the Pearl River Delta before this link existed.
The Shenzhen-Zhongshan Link slashes travel time. What once took hours now takes mere minutes. The \u56ed\u5cad2\u6865 plays a vital role in this transformation. It is more than just concrete and steel.
This bridge is a crucial artery for the region. Consider the economic impact. The \u56ed\u5cad2\u6865 facilitates trade and travel. It helps connect major urban clusters. These include Shenzhen-Dongguan-Huizhou and Zhuhai-Zhongshan-Jiangmen.
Look at its design. The Shenzhen-Zhongshan bridge boasts impressive features. The Zhongshan bridge section has a double-tower cable-stayed structure. It measures 1,170 meters in length with a standard width of 40.5 meters. This makes it the widest cross-sea steel box girder of its kind globally.
Consider the Lingdingyang bridge section. Its main span reaches 1,666 meters. The main tower stretches 270 meters high. It also features a global height record net headway of 76.5 meters. It is the world’s largest offshore steel box girder suspension bridge.
The entire Shenzhen-Zhongshan Link incorporates an undersea tunnel. This tunnel extends approximately 6.8 kilometers. About 5 kilometers consist of immersed pipeline. These pipelines utilize 32 pipe joints and one final joint. It represents the world’s longest and widest undersea steel-tube-shell immersed tunnel.
Think about the immersed tube tunnel. Each standard tube section measures 165 meters long. It has a width of 46 meters and a height of 10.6 meters. During construction, each tube section required about 29,000 cubic meters of self-compacting concrete.
Note the sheer scale of this undertaking. The Shenzhen-Zhongshan Link also features the world’s first underwater expressway interchange. It is located at the airport interchange. Also, the world’s widest repeatedly foldable M-shaped water stop is here. It is in the final joint of an immersed tube tunnel.
Picture the flurry of activity during construction. Many companies contributed to this colossal project. These included China Railway Liuyuan Group Co. and China Railway Major Bridge Engineering Group Co. Their combined expertise brought this vision to life.
Let us appreciate the \u56ed\u5cad2\u6865. It is a critical element of the Shenzhen-Zhongshan Link. As you stand here, you are witnessing a symbol of progress. This bridge embodies China’s ambition and engineering prowess.
