Jacking tube coupling 4 is released in the elongation of flexible yoke frame 15 in the reversible immersed tube tunnel final connector of item embodiment, until with
Pipeline section 2 is installed accurately to dock；If posture when jacking tube coupling 4 is released cannot achieve and install the accurate of pipeline section 2 and dock, lead to
The contraction for crossing flexible yoke frame 15 retracts jacking tube coupling 4, releases again after adjusting the posture of jacking tube coupling 4.
S2: after jacking tube coupling 4 with installed after pipeline section 2 accurately dock, discharge and has been installed between pipeline section 2 jacking tube coupling 4
Water in binding cavity 11, and sealing is carried out with 2 place of docking of pipeline section has been installed to jacking tube coupling 4.It should be noted that jacking tube coupling
4 can crimp sealing cooperation progress with the sealing installed at 2 docking of pipeline section by first of waterstop 17 of setting with waterpower.
S3: after sealing reaches requirement, by thrust component 7 be connected to the first counter-force bracket 5 and the second counter-force bracket 6 it
Between, to 4 thrust of jacking tube coupling.It should be noted that when using including the first thrust bracing members 71 and the second thrust bracing members
When 72 thrust component 7, since the first thrust bracing members 71 are with the release synchronizing moving of jacking tube coupling 4, thus, in this step,
It only needs for the second thrust bracing members 72 to be connected between the first thrust bracing members 71 and the second counter-force bracket 6.It needs to illustrate
If found after thrust jacking tube coupling 4 with the docking there are error of pipeline section 2, the second thrust bracing members of dismantling have been installed
72, by stretch yoke frame 15 contraction jacking tube coupling 4 is retracted, adjust jacking tube coupling 4 posture after release again, again into
The operation of row step S2 and this step.
S4: after thrust reaches requirement, the gap injection concrete between section pipeline section 1 to jacking tube coupling 4 and is secretly buried, is made
Jacking tube coupling 4 is connected as one with section pipeline section 1 is secretly buried, and is carried out welding with the place of docking for having installed pipeline section 2 to jacking tube coupling 4 and applied
Work completes docking.
Reversible immersed tube tunnel final connector provided by the utility model passes through the flexible yoke frame 15 of setting, thrust group
The mating reaction of part 7, the first counter-force bracket 5 and the second counter-force bracket 6, it can be achieved that reversible construction when jacking tube coupling 4 docks, this
The flexible operation mode of the reversible construction of kind is easy, and without carrying out underwater operation, construction risk is small.Moreover, practical using this
When the reversible immersed tube tunnel final connector of novel offer carries out docking construction, mainly construct complete under dry operating environment
At underwater operation is few, and construction quality is guaranteed, and short construction period is small by water depth effect, and construction cost is low.
