Description
Technical Field

Background
With the rapid advance of the urbanization process in China, a large number of long and large tunnels are built or planned in the east alluvial plains, river delta and offshore areas of China in succession. The immersed tube tunnel is a common form of the tunnels, 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. All procedures of foundation trench excavation, pipe section prefabrication, floating transportation and sinking, internal paving and the like can be operated in parallel, and mutual interference is less. The prefabrication quality of the pipe section is easy to control. The immersed tunnel is constructed by prefabricating tunnel pipe sections in sections, arranging temporary water-stopping heads at two ends of each section, then floating to the axis of the tunnel, sinking in a pre-dug geosyncline (foundation trench), completing underwater connection between the pipe sections, removing the temporary water-stopping heads, backfilling the foundation trench to protect the immersed pipes, and laying internal facilities of the tunnel, thereby forming a complete underwater channel.
Although the immersed tube tunnel has many advantages, there are many difficulties in the process of joint treatment, and the pipe joint is an important part and the weakest part of the immersed tube tunnel, so the pipe joint must have good water tightness.

However, the joint connection structure of the immersed tube tunnel has some defects in waterproof and earthquake-proof. For example: after the pipe joints of the immersed tunnel are butted, the stress on the cross sections of the pipe joints is uneven, so that the overall anti-seismic performance is reduced; in the long-term use process, the small deformation or dislocation between pipe joints is caused under the action of external force such as seabed waves and the like, so that the waterproof performance is influenced; it is impossible to know whether there is water accumulation between the GINA waterstop and the OMEGA waterstop, and further, it is impossible to take a waterproof measure in advance accurately.
