Cross-Harbour Tunnel of Hong Kong-Zhuhai-Macao Bridge 1
The Hong Kong-Zhuhai-Macao Bridge across Lingdingyang connects Hong Kong, Zhuhai and Macao, and the whole project is very large in scale. The main project consists of three parts, of which the island tunnel project is the most critical and difficult part. The main project of Guangdong, Hong Kong and Macao is about 29.6 kilometers long, with a total length of 22 kilometers, 69 kilometers of bridge engineering and 69 kilometers of bridge engineering. It consists of a 7-kilometer-long submarine immersed tunnel. There are two artificial islands at both ends of the tunnel, facing each other across the sea.
2. Xiang 'an Cross-Harbour Tunnel
Located in Xiamen, the total length of the tunnel is 695 kilometers, the total length of the tunnel is 5 kilometers, the sea area is 4.2 kilometers, and the deepest part is about 70 meters above sea level. As the largest subsea tunnel in the world, Xiang 'an Tunnel has a span of170m2, a span of170m2 and a height of13.5m.. It adopts the form of three-hole tunnel, with three lanes on both sides of the main tunnel, and the service tunnel in the middle hole is the municipal pipe gallery, maintenance and escape passage.
3. Jiaozhou Bay Cross-Harbour Tunnel
It is connected to Xuejiadao Sub-district Office, Huangdao District, Qingdao in the south, Tuandao in the main city of Qingdao in the north, and goes under the JIAOZHOU Bay. The total length of the tunnel is 7.8 kilometers, of which the cross-harbour tunnel is about 30 kilometers long. The design speed is 80 kilometers per hour. The tunnel is located at the mouth of Jiaozhou Bay, connecting Qingdao and Huangdao, with six lanes in both directions.
4. Shiziyang Tunnel in Guangzhou-Shenzhen-Hong Kong
Shiziyang Tunnel of Guangzhou-Shenzhen-Hong Kong High-speed Railway is the key project of Guangzhou-Shenzhen-Hong Kong High-speed Railway crossing Shiziyang waters, and it is also the first underwater railway tunnel in China, which is known as China Century Railway Tunnel. The tunnel is located in Shiziyang, Pearl River Estuary, Guangdong Province, with tung chung station in Guangzhou in the west and Humen Station in Dongguan in the east.
5. Qingdao Metro 1 Line Cross-sea Tunnel
The subsea tunnel of Qingdao Metro 1 Line starts from Wawuzhuang Station in West Coast New District. After crossing the JIAOZHOU bay estuary north along the east side of JIAOZHOU bay tunnel, it will land on Tuandao and connect with Guizhou Road Station in the main city of Qingdao. The total length of the tunnel is about 8. 1 km, of which the sea area is about 3 km long. As the most important control project of the subway 1 line, the cross-harbour tunnel is not only the first cross-harbour tunnel in China, but also the deepest and longest cross-harbour tunnel in China.
6. Hong Kong Cross-Harbour Tunnel
The Hong Kong Cross-Harbour Tunnel is three intermittent cross-harbour tunnels, including nine central tunnels, nine eastern tunnels and western tunnels in Hong Kong. They span Victoria Bay, connecting Hong Kong Island and Kowloon Peninsula. Middle Road Cross-Harbour Tunnel is the first cross-sea traffic tunnel in Hong Kong, with a total length of 1.86km, including a four-lane traffic tunnel and a subway tunnel, with a daily flow of1.2000 times.
7. Shantou Bay Tunnel
Located between the Bay Bridge and the Stone Bridge, it is the first undersea tunnel built in the seismic intensity zone of 8 degrees in China and the most difficult large-diameter shield tunnel in China. The project connects the northern and southern urban areas of Shantou City, starting from the intersection of Tianshan South Road and Jinsha East Road, laying along Tianshan South Road, passing through Changping East Road and Zhongshan East Road, passing through Suai Bay in the southeast of Overseas Chinese Park, landing on the west side of South Bank Diving Hall, and ending at the entrance and exit on the north side of Hutoushan Tunnel under construction.
8. Haicang Cross Harbour Tunnel
Haicang Tunnel is a passage connecting Haicang District and Xiamen Island. The starting point is located at the intersection of Ma Qing Road and Haicang Avenue in Haicang District, and the ending point is located at Torch North Road in Xiamen Island. The main line is two-way and six-lane, with a design speed of 80 km/h. This project is of great significance for alleviating the traffic pressure in and out of the western part of Xiamen Island and promoting the cross-island development process.
9. Cross-sea tunnel between Dalian Metro Line 5 Railway Station and Suoyuwan South Station.
There are 24 lines in Dalian Metro Line 5, with a total length of 484 kilometers, with 8 stations10, of which the length from the railway station of the whole line control project to the south station of Suoyuwan is 2882 meters, and the sea area of Dalian Suoyuwan is 23 10 meters. It is the world's first large-scale shield tunnel in karst stratum, the longest large-scale shield tunnel in hard rock stratum in China and the largest subway tunnel in China.
Dalian Bay Cross Harbour Tunnel 10
Dalian Bay Cross-sea Tunnel Project is invested and constructed by PPP cross-sea immersed tube mode, connecting Renmin Road, the main road in Zhongshan District, to the south and No.20 Road in Barracuda Bay to the north. Including submarine immersed tunnel engineering, land tunnel engineering, wiring road engineering, etc. Need to install 18 large immersed tube. The standard pipe length is 180m, and the weight of a single immersed pipe is about 60,000 tons, which is equivalent to the displacement of a medium-sized aircraft carrier.
