广州洲头咀隧道
Guangzhou Chaotou Tsui tunnel
在珠江340米长的水中段采用沉管隧道形式,是亚洲最大的变截面过江沉管隧道,也是国内首次沉管水下变截面管段连接。
首先在岸上预制沉管,然后把巨大的管道放入江底,沉管完成拼装即形成一条完整的隧道。沉管段中第一节(连接海珠区)及最后一节(连接荔湾区芳村)均为截面大小不同的变截面管段,最大宽度39.36米,比标准段宽度31.4米大7.96米,需精确计算管段浮心,让又重又大的沉管按设计安放,不差丝毫。

洲头咀隧道,全长2200米,立交桥最大单跨超过50米,属于半互通式立交,由于节点用地条件和接线条件的限制,在隧道以南、洪德路以西设置了两个匝道以同向螺旋圆的形式连接隧道和内环路,分别解决了南往西方向及西往南方向的交通。

Chau Tau Tsui Tunnel, with a total length of 2,200 meters and a maximum single span of overpasses of over 50 meters, is a semi-inter-interchange interchange. Due to the site conditions and wiring conditions of the nodes, two ramps are set to the south of the tunnel and to the west of Hongde Road Connecting the tunnel and the inner loop to the spiral circle solves the traffic from south to west and from west to south respectively.

  In the Pearl River 340-meter-long water immersed tunnel in the form of the Middle East, is Asia's largest variable cross-river immersed tunnels, but also for the first time immersed pipe underwater variable cross-section pipe connection.
