End housing, the periphery of the first firm end housing is provided with GINA waterstops, and end seal wall is provided with the adjacent long joint in both sides；Described list
The both sides of face wedge are provided with the second firm end housing.
Preferably, described one side wedge long joint top adjacent with both sides, base plate, pouring in the connection cavity of side wall
There is shearing concrete.
Preferably, setting slip casting between the FS final spice bottom of the adjacent long joint in described both sides and blinding layer.
Preferably, described one side wedge is using prefabricated.
Operation principle of the invention is：Long joint end face is provided with waterstop, by the deadweight of one side wedge and very heavy
Top pushing tow is close to the wedge-shaped end face occlusion of one side wedge long joint adjacent with both sides, and compression waterstop reaches water-stagnating effect.
After said structure, what the present invention was produced has the beneficial effect that：A kind of immersed tube tunnel final of the present invention connects
The structure type of head, immersed tube final joints structure size is small, and prefabricated convenience, construction quality is easily guaranteed that；One side wedge shape, construction is difficult
Degree is small, it is easy to which waterstop compresses, and FS final spice block is difficult to be extruded by water pressure；Prefabricated components underwater mating, speed of application is fast, pole
The difficulty of construction of artificial underwater operation workload and final structure is reduced greatly, there is very big promotional value.
