7 -minute drive runs through!Shantou Bay Tunnel opened on September 28

On September 26, the Traffic Police Detachment of the Shantou Public Security Bureau issued the "Notice on the General Line of the Shantou Bay Tunnel" stating that the main line of Shantou Bay Tunnel Engineering on both sides of the north and south of the Nei Bay has passed the acceptance conditions. It will be opened at 10 am.

The Shantou Bay Tunnel runs through the Bay of Shantou, with a total length of 6680 meters. It adopts first -level highway technical standards and sets two -way six -lane lanes. The design speed is 60 kilometers per hour. The project starts at the intersection of Tianshan South Road and Jinsha East Road in Longhu District, North Bank. It crosses the Bay of Sue and goes ashore at 200 meters on the west side of the diving hall on the south bank. The mountain tunnel is connected to the main urban area of ​​Qijiang. The tunnel is divided into three layers, the upper layer is a smoke discharge passage, the middle layer is a driving lane, and the lower layer is a personnel evacuation and a comprehensive pipe corridor channel. The north -south coast of the tunnel also set up a wind tower about 60 meters high as a ventilation facility for the tunnel. The tunnel opens a new channel across the sea on both sides of the south and south of Shantou. Free traffic will be implemented after opening. The fastest driving time on both sides of the strait will only take 7 minutes.

At present, Shantou is accelerating the construction of the city's urban development pattern. After the opening of the Shantou Bay Tunnel, it breaks the time and space distance between Shantou's main urban area and Nanbin New City. Xiao Guanping, the general manager of CITIC Shantou Binhai New City Investment Development Co., Ltd. and chairman of Shantou Susou Channel Construction Investment Development Co., Ltd., said that after the opening of the Gulf Tunnel, the north -south coast of Shantou achieves all -weather traffic. It is more unobstructed, which is conducive to promoting the "one bay" to fly together than the wings, and promote the high -quality development of Shantou's economy and the development of the coastal economic belt.

The Shantou Gulf Tunnel is the world's first large diameter shield tunnel located in the 8 -degree earthquake intensity area. It is also the first largest underwater highway engineering shield tunnel in China. Construction is hailed by industry experts as "world -class challenge projects."

It is worth mentioning that the shield of the western line of Shantou Bay Tunnel adopts the first domestic large -diameter mud shield machine with independent intellectual property rights. This device integrates the five innovative points of the integrated design of the ultra -high pressure capacity system, the technique of constant pressing knife, the main driver technology of the telescopic swing type, the double gas road pressure control technology, and the high degree of intelligence. High degree of operation, high ground settlement control accuracy, safe and efficient, and have unique advantages in the construction of a series of Jiangyuehai Tunnels in my country. New record of the project.

Shi Qu, manager of the engineering management department of Shantou Sudou Channel Construction Investment Development Co., Ltd., said: "This project has obtained 14 invention patents, 9 of which are practical. In addition, there are 5 innovations in engineering laws and 2 in scientific and technological inventions. The item, one is a stone -throwing area, and there is a software application, that is, the whole process of information management. "
