Before rubber ring, adjust it is all to adjust the annular adjustment structure internal diameter that pressing plates to be formed maximum, can be convenient in this way tube coupling into
Enter.
The front end of tube coupling is put into Tunnel doorway, and adjusts all adjusting pressing plates, the ring-type formed it by step 803
Inside diameter is identical as tube coupling diameter.
Specifically, adjusting all adjusting pressing plates after the first root canal section front end enters the first cord rubber ring and making shape
At annular adjustment structure internal diameter it is identical as the diameter of tube coupling, and push pipe hereafter during keep the internal diameter constant, in this way
Effective compacting can be formed to the first cord rubber ring during push pipe, avoid during main top oil cylinder is retracted by
In changes of voids mud is revealed, to solve the problems, such as that the first cord rubber ring turns up, it is therefore prevented that tunnel portal sealing
It is destroyed.
End in contact after step 804, main top oil cylinder front end and tube coupling starts push pipe.
It should be noted that in step 804, needed replacing if cord rubber ring damages during push pipe,
First stop the movement of main top oil cylinder, and injects filler into the annular seal inner tube of a tyre for having certain telescopic resilience from valve and be allowed to
Tube coupling is expanded and wrapped up, then demounting bolt carries out the replacement of cord rubber ring, after replacement, will be provided with by valve centainly flexible
Filler in the annular seal inner tube of a tyre of elasticity discharges and starts the movement of main top oil cylinder, continues push pipe.
Further, if carrying out push pipe operation in the biggish situation of hydraulic pressure in long-distance pipe jacking operation or tunnel,
Before step 804, filler can also be injected into the annular seal inner tube of a tyre for have certain telescopic resilience by valve and be allowed to
Expand and wrap up tube coupling, in this way can to avoid during main top oil cylinder push pipe due in tunnel pressure it is excessive and lead to tube coupling
It retreats.
Step 805, behind tube coupling top to predeterminated position, first pass through valve into the annular seal inner tube of a tyre for having telescopic resilience
Injection filler is allowed to expand and wrap up tube coupling, then main top oil cylinder is retracted.
After step 806, main top oil cylinder exit tunnel portal, it will be provided in the annular seal inner tube of a tyre of telescopic resilience by valve
Filler release.
