Portable composite water-stop system
Technical field
Immersed tube tunnel technical field is the utility model is related to, particularly a kind of portable composite water-stop system.
Background technology
Immersed tunnelling method constructing tunnel, exactly partly latent refute or dry-docking in prefabricated tunnel caisson difference transportation by driving to making a reservation for
The docking of position sinking, is longer than the metric space of the pipeline section to make the sinking of final section pipeline section smoothly to leave, the remainder away from
Pipeline section from the sinking docking of space institute is considered as FS final spice.The immersed tube tunnel final joint is the key of immersed tube tunnel construction,
Particularly off-lying sea overlength immersed tube tunnel construction, job site operating condition is difficult, is faced with the oceans such as wave and the ocean current of complexity
Environmental condition and meteorological condition.
The structure of immersed tube tunnel final joint is as shown in figure 1, FS final spice 1 is set with the periphery that adjacent tube coupling 2 is connected side
There is toroidal cavity, jack 3 and pushing tow girder 4 are provided with toroidal cavity, the end of pushing tow girder 4 is parallel to FS final spice
End face, the end face of pushing tow girder 4 are provided with Gina waterstops 5, and Gina waterstops 5 are before the end face of pushing tow girder 4, the girder
The material for holding Gina waterstops 5 is natural rubber, is fixed on by casting die system in the end chamfer of girder, waterstop and casting die
System is each perpendicular to girder end chamfer.Waterstop is enclosed along girder end chamfer arrangement one, and top is connected on the piston rod of jack 3
Girder 4 is pushed away, Gina waterstops 5 contact, Gina waterstops 5 in the presence of pushing tow girder 4 with having installed the adjacent surface of tube coupling 2
Binding cavity and extraneous sealing are realized after being sufficiently compressed, the binding cavity draining after being easy to, forms dry construction environment.
In above-mentioned work progress, pushing tow girder 4 can produce cavity clearance in movement between the cover plate 6 of FS final spice,
Seawater can be entered in pushing tow girder by the cavity clearance, so as to have influence on postorder drainage procedure, cause FS final spice can not
Installation is normally completed, therefore, if effectively preventing the sky that seawater is entered between the pushing tow girder of relative movement and FS final spice
Chamber, become a most important link in FS final spice work progress, once seawater is entered in pushing tow girder, by direct shadow
Ring normal, the safe construction to FS final spice.
Similarly, when two relative movement component between need to realize sealing under mobile status when, be equally faced with as
What realizes the problem of sealing.In the prior art, the effect of sealing is mainly reached by sealing, and for two relative movement components
Between be then difficult to sealing and sealing, and due to being relatively moved between two components, it is easy in sealing position hair
Raw seepage, so as to lose water stopping function, and sealing, sealing how are realized between two relative movement components, turn into a skill
Art problem.
Utility model content
Goal of the invention of the present utility model is:For in the prior art can not be between two relatively-movable components
Carry out hermetic seal, and the problem of existing water-stagnating effect is poor, service life is short during using single antipriming, there is provided
