Background

With the development of infrastructure technology, the construction of remote sea-crossing channels generally adopts a mode of combining bridges and tunnels at present, and the commonly used mode of constructing the submarine channels comprises two modes, wherein one mode is to use a shield machine to open a tunnel below a seabed so as to form the submarine channel, and the other mode is to lay a plurality of immersed tubes on the seabed so as to form the submarine channel by communicating the plurality of immersed tubes. The immersed tube tunnel has lower requirements on the foundation, and is particularly suitable for engineering places where soft foundations, riverbeds or seabed are shallow and foundation trench excavation is easy to carry out by using water dredging facilities. Because of the small buried depth, the total length of the tunnel line including the connecting section is obviously shortened compared with the tunnel constructed by adopting a mine method and a shield method. The section shape of the immersed tube can be round or square, and the selection is flexible. The procedures of foundation trench excavation, pipe section prefabrication, floating transportation and sinking, internal paving and the like can be operated in parallel, the mutual interference is less, and the pipe section prefabrication quality is easy to control, so that the importance is more and more paid.

The construction steps of the immersed tube tunnel comprise foundation trench excavation, foundation construction, immersed tube installation, joint treatment and the like, wherein the foundation trench excavation is to open a foundation trench by selecting equipment such as a bucket excavator, a suction dredge or a dredge with a mud cutting head, a crane with a claw bucket and the like; the foundation construction comprises paving the rough stones firstly and paving the fine stones secondly.
