Recently, the shield machine on the east line of the Shantou Bay Tunnel set a record high by driving 8 rings (16 meters) per day. As of January 3, 225 rings of segments have been installed along the eastern route, totaling 450 meters, of which 280 meters are located at the seabed.
The Shantou Bay Tunnel has a total length of 6.68 kilometers and is divided into two lines and two tunnels of east and west, and the shield method is adopted for its construction. The east line of the tunnel adopts the German Herrick 15.01-meter large-diameter shield for driving, while the west line adopts the 15.03-meter large diameter shield independently manufactured by our country for driving in the same direction as the east line. Such a large diameter and long distance practice of passing through the bay is the first of its kind in the country. After the tunnel is completed, it is a two-way six-lane way , and the driving speed of the main line is designed to be 60 km/h. The interior space will be divided into three layers, among which, the top is the smoke passage, the middle is the three-lane traffic layer, and the bottom is the rescue passage and pipe gallery.

汕头海湾隧道施工大提速
近日，汕头海湾隧道东线盾构机创下了日掘进8环（16米）的历史新高。截至1月3日，东线已安装管片225环，合计450米，其中280米位于海底位置。
汕头海湾隧道全长6.68公里，分为东西两条线路、两座隧道，采用盾构法施工。隧道东线采用德国海瑞克15.01米大直径盾构掘进，西线采用我国自主生产的15.03米大直径盾构同向掘进，如此大直径、长距离穿越海湾在国内还属首次。隧道建成后为双向六车道，主线设计行车速度60千米/时，内部空间分为三层，顶部为排烟通道，中部为三车道行车层，底部为救援通道及管廊。
