2021-11-02
Since the East Main Tower of Zhongshan Bridge of Shenzhen China channel, the core hub project in Guangdong, Hong Kong and Macao, has also been successfully capped, recently, with the completion of sinking of E31 pipe joint of immersed tunnel of Shenzhen China channel, it has been successfully connected with E32, the first pipe joint at the east end of the project. So far, the sinking and docking of 14 pipe joints have been completed in the immersed tunnel. On December 28, 2016, Lingdingyang broke the tranquility of the past. The construction of West Rengong Island cofferdam, the first project of Shenzhen Zhongshan river crossing channel (hereinafter referred to as "Shenzhen China channel"), was started in the water area of the middle beach. Another sea crossing project in the Great Bay area of Guangdong, Hong Kong and Macao followed the construction of Hong Kong, Zhuhai and Macao Bridge. As the only direct highway connecting the two major functional groups of the Pearl River Delta "Shenzhen Dongguan Hui" and "Pearl River", it is also a traffic link connecting China's Guangdong pilot free trade zone (Guangzhou Nansha, Shenzhen Qianhai and Zhuhai Hengqin). The Shenzhen China channel has great economic and social significance. In the past five years, the butterfly transformation has been completed from the first pile to the pile foundation and bearing platform of the main bridge, which means that the deep and medium channel project brewing since 1998 has come to reality from paper, and the idea of flying over the East and west sides of the Pearl River by one bridge has come to reality.
