According to CCTV, the Hong Kong-Zhuhai-Macao Bridge under construction is welcoming major nodes. The last giant immersed pipe E30 of the Subsea Tunnel was successfully installed today. The total length of the completed tunnel reached 5,652 meters, only 12 meters from the final closure. .
The Hong Kong-Zhuhai-Macao Bridge has a total length of 5,664 meters and is constructed by the jointing of 33 giant immersed tubes. It consists of 28 straight section immersed tubes and 5 curved section immersed tubes. It is the longest road immersed tunnel in the world and the only deep The immersed tube tunnel is also the first offshore immersed tunnel in China, with a maximum installation depth of more than 45 meters.
On May 1, 2013, the first section of the immersed pipe was installed.
The last section of the E30 immersed pipe is 171 meters long and is trapezoidal. It is located on the east side of the subsea tunnel at Helongkou. It is the last gateway to ensure the successful installation of the Hong Kong-Zhuhai-Macao Bridge undersea tunnel. The accuracy requirements are unprecedented.
On the morning of the 6th, the E30 was escorted by 13 high-powered tugboats and 10 maritime guard boats. It took 13 kilometers and 7 hours to reach the construction area under the towage of the installation fleet. It sank at a uniform speed of 30 centimeters per minute. The precise docking of the completed tunnel has been completed. The key indicators such as the axis, longitudinal slope, and elevation of the Shanwei meet the design standards.
The total length of the Hong Kong-Zhuhai-Macao Bridge is 55 kilometers. It is composed of the world's first bridge island tunnel cluster. The bridge project was completed last year. After the opening of the whole line, the time from Zhuhai to Hong Kong will be shortened from over 3 hours by land and 1 hour by water to within 30 minutes. It will be the first land connection between Zhuhai, Macau and Hong Kong, and the west end will be linked to Beijing-Hong Kong-Macao Expressway and the national high-speed network. The side connects the Hong Kong regional road network through the Lantau Highway.
