in October 23rd, the opening ceremony of the Hong Kong Zhuhai Macao Bridge was held in Zhuhai, Guangdong. President Xi Jinping attended the ceremony and announced that the bridge was officially opened. What is the best Hong Kong Zhuhai Macao Bridge in the world? The Zhuhai Macao bridge spans Lingdingyang, connecting Hong Kong in the East and Zhuhai and Macao in Guangdong in the west, with a total length of about 55 km. It is the first super large cross sea traffic project jointly constructed by Guangdong, Hong Kong and Macao. The Hong Kong Zhuhai Macao Bridge will be opened to traffic on October 24. The Macao port management area and related connecting roads will be opened at 3 p.m. on October 23. With the completion of the Hong Kong Zhuhai Macao Bridge, the construction of Guangdong, Hong Kong and Macao Bay area has entered the "fast lane".
It is understood that the Hong Kong Zhuhai Macao Bridge is the first super large cross sea transportation project jointly constructed by Guangdong, Hong Kong and Macao under the framework of "one country, two systems". It is also another major infrastructure construction project in China after the Three Gorges Project and the Qinghai Tibet railway. The whole project includes the main works of the bridge and tunnel in the sea, Hong Kong connecting line, Hong Kong port, Zhuhai connecting line, Macao connecting line and Zhuhai Macao gate The main works include a 22.9 km bridge, a 6.7 km subsea tunnel and an east-west artificial island connecting the tunnel and the bridge. It has the longest overall span, the longest steel structure bridge and the longest subsea immersed tube tunnel in the world. It took more than ten years from the early planning to the completion of the project, in which the main project of the bridge has been constructed for nearly nine years.
When the Hong Kong Zhuhai Macao Bridge is completed and opened to traffic, it will be the first time to realize the land docking between Zhuhai, Macao and Hong Kong, greatly shortening the distance between Hong Kong, Zhuhai and Macao. By then, the transportation time between Zhuhai and Hong Kong will be shortened from about one hour by water and more than three hours by land to 20-30 minutes. 'the Hong Kong Zhuhai Macao Bridge has completely ended the traffic problem between Hong Kong and the West Wing of the Pearl River Delta. "Liang gangrui, former president of the Hong Kong Institute of transport and logistics, said that for a long time, Hong Kong could only enter the mainland through Shenzhen. The route was too simple and the radiation was greatly reduced. After the opening of the Hong Kong Zhuhai Macao Bridge, Hong Kong has formed a close connection with the cities on the West Bank of the Pearl River, providing greater space for Hong Kong's industrial transfer.
The completion and opening of the Hong Kong Zhuhai Macao Bridge will greatly enhance the economic competitiveness of the Pearl River Delta region. Yuan Ping Ping, deputy director of the Hong Kong Macao Pearl River Delta Research Center of Sun Yat sen University, said that the completion of the Hong Kong Zhuhai Macao Bridge will enable the West Bank of the Pearl River and Hong Kong and Macao to take the lead in forming a unified market, improve the economic integration of the three places, and make Guangdong, Hong Kong and Macao Bay area one of the most dynamic economic regions in the world.
In the future, traffic infrastructure in Guangdong, Hong Kong and Macao will be further strengthened. Guangzhou Shenzhen Hong Kong high speed railway, pearl river channel, Humen second bridge, Guangzhou second airport, Pearl River Delta trunk airport, Pearl River Estuary port resource integration, etc. will strongly support the interconnection and external exchange of people flow, logistics flow, capital flow, information flow, etc. in Dawan district.
What is the best Hong Kong Zhuhai Macao Bridge in the world?
'the longest cross sea bridge ',' The Longest Undersea Tunnel ',' the most advanced island building technology '& hellip; Tomorrow (October 24) at 9 am, the Hong Kong Zhuhai Macao Bridge, known as the 'Mount Everest' in the bridge industry, will be officially opened to traffic. This 14 year 'super' sea crossing bridge, from design to construction, has set many of the world's best, and has been hailed by the guardian as one of the 'Seven Wonders of the modern world'.
The Hong Kong Zhuhai Macao Bridge, with a total length of 55 km, consists of three navigable bridges, one subsea tunnel, four artificial islands and connecting bridges and tunnels, non navigable continuous girder bridges in deep and shallow water areas and land connecting lines of Hong Kong, Zhuhai and Macao.
It is understood that the Hong Kong Zhuhai Macao Bridge is the longest sea crossing bridge in the world, or the most difficult one in the world. At the same time, the Hong Kong Zhuhai Macao Bridge has 15 kilometers of all steel box girder, which is the longest steel bridge in the world.
The Hong Kong Zhuhai subsea tunnel, the longest in the world, is the Hong Kong Zhuhai subsea tunnel with a total length of 48.7 meters. At the same time, the Hong Kong Zhuhai Macao Bridge also has the largest immersed tunnel. The standard pipe section of the immersed tunnel is 180 meters long and the displacement is more than 75000 tons.
In terms of engineering construction, the Hong Kong Zhuhai Macao Bridge adopts the world's first deep inserted steel cylinder rapid Island forming technology. 120 giant steel cylinders are directly fixed on the seabed, inserted into the seabed, and then filled in the middle to form an artificial island. The diameter of each round steel tube is 22.5 meters, almost as big as the basketball court, and the height is 55 meters, which is equivalent to the height of 18 floors. Its deep-water highway immersed tube tunnel without docking is also the most difficult in the world. When immersed tubes are not docked on the seabed ranging from 13 meters to 48 meters below sea level, the docking error must be controlled within 2 cm.
