In the final joint of the immersed tube tunnel, the first connecting tube 31 and the second connecting tube 32 are sleeved with each other and can slide relatively in the axial direction, so that the first tube segment 1 and the second tube segment 2 can move relatively in the axial direction. In the butt joint construction, the first butt joint end can be abutted with the installed pipe section of the joint by pulling the first pipe section 1 to the installed pipe section close to the first pipe section, and the second butt joint end can be abutted with the installed pipe section of the joint by pulling the second pipe section 2 to the installed pipe section close to the second pipe section. During butt joint, the second water stop belt 42 arranged on the end face of the first butt joint end and the end face of the second butt joint end can stop water at the joint of the pipe joints, and the first water stop belt 41 arranged at the joint of the first connecting pipe 31 and the second connecting pipe 32 can ensure the water stop effect between the first connecting pipe 31 and the second connecting pipe 32.

As a preferred example, the first water stop 41 is an M-shaped rubber water stop, and those skilled in the art can use other types of water stops as the first water stop 41 as long as it can expand and contract in the axial direction to ensure the water stop effect.
In order to prevent the first water stop 41 from being damaged by being subjected to external water pressure, it is preferable that the outer cover of the first water stop 41 is provided with a protection cover 5 as shown in fig. 2. Specifically, the protection cover 5 is formed by a first cover body 51 and a second cover body 52 that are mutually sleeved, the first cover body 51 is fixedly connected to the first connecting pipe 31, the second cover body 52 is fixedly connected to the second connecting pipe 32, and the first cover body 51 and the second cover body 52 can relatively move along with the relative sliding of the first connecting pipe 31 and the second connecting pipe 32. It should be noted that, the first cover 51 and the second cover 52 may be made of steel plates, so as to ensure that they can withstand a large water pressure. It will be appreciated that other structures of the protective cover 5 may be used by those skilled in the art, as long as it can withstand a large water pressure and function to protect the first water stop 41.
Further, as shown in fig. 4, the second water stop 42 is disposed along the circumferential direction of the first pipe section 1 or the second pipe section 2, and thus the second water stop 42 disposed can ensure no water seepage along any circumferential position of the first pipe section 1 or the second pipe section 2, thereby ensuring a water stop effect. It should be noted that the second water stop 42 may be a GINA water stop, and those skilled in the art may also use other types of water stops as the second water stop 42, so long as the water stop function is achieved.
In order to ensure that the first pipe joint 1 and the second pipe joint 2 still keep coaxial when relatively moving, as shown in fig. 3 and 4, a guide post 7 is arranged in the first pipe joint 1, the guide post 7 is axially arranged, a limiting block 8 for limiting the guide post 7 to move only axially is correspondingly arranged in the second pipe joint 2, and a limiting hole 9 capable of penetrating through the guide post 7 is arranged on the limiting block 8. When the first pipe joint 1 and the second pipe joint 2 move relatively, the guide post 7 is always limited in the limiting hole 9, so that the guide post can only move axially, and the first pipe joint 1 and the second pipe joint 2 are ensured to always keep coaxial when moving relatively.
