Description
Technical field
The present invention relates to object mobile field, more particularly to a kind of slip system.
Background technology
Immersed tunnelling method constructing tunnel, exactly partly latent refute or dry-docking in prefabricated tunnel immersed tube 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 the equal Immersed tunnel in both ends of FS final spice, i.e. tunnel connection, and in marine docking
Closure, last closure pipeline section is 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 marine environment bars such as wave and the ocean current of complexity
Part and meteorological condition.
As shown in figure 1, the length of FS final spice 1 is less than the spacing of two interfaced section immersed tube 2, pacify in FS final spice 1
After being attached to position, the pushing tow of closed circular pushing tow girder 11 that the both ends of FS final spice 1 are set respectively simultaneously drives the waterstop 3 of closed circular
It is brought into close contact in the end face of immersed tube 2, FS final spice 1 is docked with immersed tube 2, pushing tow girder 11 is arranged on the groove on FS final spice 1
In 12, the cross section of groove 12 and pushing tow girder 11 is annular, for the ease of pushing tow girder 11 and the Matching installation of groove 12
And follow-up watertight processing, 7-9cm accumulation space between pushing tow girder 11 and groove 12 being present, (i.e. the width of groove 12 subtracts
The width in the space obtained after the width of pushing tow girder 11), because the cross sectional dimensions of the pushing tow girder 11 of immersed tube tunnel reaches
35 × more than 10m, belongs to super large structural member, and pushing tow girder 11 is in groove 12 due to can not be completely equal in pushing tow moving process
Weigh stress, and inevitably shake (particularly S-shaped displacement is rocked), and pushing tow girder 11 is easily stuck in groove 12,
The moving process of pushing tow girder 11 occurs behind implantation seabed, stuck to cause FS final spice 1 to dock failure with immersed tube 2 and be difficult to draw
Return, cause whole immersed tube tunnel project failure, therefore width is rocked, it is necessary to ensure to reduce when pushing tow girder 11 moves in groove 12
Degree, it is stuck in groove 12 to be unlikely to pushing tow girder 11.
The content of the invention
It is an object of the invention to overcome the pushing tow girder in the presence of prior art to belong to super large structural member, it is in groove
In middle pushing tow moving process due to can not fully equalize stress, inevitably shake, pushing tow girder easily it is stuck
In groove, cause FS final spice docked with immersed tube failure and be difficult to retrieve, cause whole immersed tube tunnel project failure it is above-mentioned not
