Description
Technical field
This utility model is related to prefabricated immersed tube pipeline section technical field in immersed tube tunnel, and in particular to a kind of box hat outsourcing it is heavy
Pipe pipeline section preparation facilitiess.
Background technology
The pipeline section of immersed tube tunnel decides the success or failure of whole engineering, and at present, prefabrication of tube section is carried out in dry-docking, dry-docking side
Case has mobile dock scheme, fixed dry-docking scheme and batch production dry-docking scheme.
Mobile dock scheme is exactly to build or rent large-scale partly latent to refute as packaged type dry-docking, is completed on mobile dock
Pipeline section it is prefabricated, partly latent is refuted into dive in the basin built up near tunnel of haul using tugboat then, pipeline section is realized and is refuted
The separation of ship, then section floating to tunnel location is completed into sinking mating operation.
Fixed dry-docking scheme is the Large Foundation Pit made near tunnel, bottom surface absolute altitude the eating according to section floating of foundation ditch
Water depth is controlled.Pipeline section is made in fixed dry-docking, dock gate after the completion of tube manufacture, is opened, pipeline section haul is sunk to tunnel location
Put.Fixed dry-docking is divided into axis dry-docking, side again and builds several classes such as dry-docking, independent dry-docking.
Batch production dry-docking to refer to and carry out technology arrangement according to continuous-flow type prefabricated production line, and all pre- manufacturings are 24 in the Factory Building
Hour is carried out continuously, and after fixed pedestal upper, maintenance 3d, pushing tow, vacates and pour pedestal each sections forward, Xia Yijie
The sections neighbor of Duan Yugang ejections is prefabricated.So piecewise prefabricated piecewise pushing tow, until complete whole sections pour, it is overall to push up
It is pushed into shallow depressed place and carries out interim prestressed cable tensioning and form entirety, completes a fitting-out, be then shut off between shallow depressed place and pre-fabricated factory
Sliding caisson, shallow depressed place pours water, and pipeline section floating moves to deep depressed place, finally opens deep depressed place transportation by driving to sinking scene.Denmark and Sweden etc.
The workshop of immersed tube pipeline section is all had in country, and this pre-fabricated factory is adapted to Large-scale Super Long immersed tube tunnel（Or length can be obtained
The region that phase stable pipeline section is ordered）Prefabrication of tube section.The built port Zhuhai and Macao bridge of Oresund Bridge immersed tube tunnel and China
It is exactly using batch production dry-docking.
There is following defect in prior art：
（1）Mobile dock is only applicable to 4 tracks and following situation, more than 4 tracks as pipeline section is larger, fit
Partly latent refute less, rent the difficulty refuted of partly latent larger；
（2）Mobile dock separates the dive basin for needing excavation deeper in order that pipeline section is refuted with partly latent, to navigation channel and environment
Affect larger；
（3）Fixed dry-docking needs excavation Large Foundation Pit to carry out prefabricated tube section, and cost is higher and affects larger to surrounding enviroment；
（4）Batch production dry-docking floor space is larger, cost highest, is only suitable for Large-scale Super Long immersed tube tunnel.
Therefore, it is necessary to be improved to prior art.

Each 4 meters of scopes are held to pour tunneling boring concrete, remainder pours base plate, whole mid-boards and bottom 4m side wall concretes；Two
End is installed by steel end housing, steel end seal wall and guider；Pipeline section is slipped in water by jack and winch along slideway；By pipeline section support
It is transported to that two outfitting quays carry out remaining side wall and concrete roof floading condition is poured；Temporary support is removed, and water tank component is led to
Cross post-cast strip and interim manhole is arranged on inner tube segment；Post-cast strip concrete is poured, secondary fitting-out is carried out, afterwards by pipeline section support extremely
Specified location carries out sinking.
After said structure, what this utility model was produced has the beneficial effect that：
1st, the excavation of dive basin can be avoided, therefore which can reduces the impact to environment, reduce construction costs, while not receiving
Immersed tube tunnel of the restriction that partly latent is refuted suitable for all scales；
2nd, the excavation of Large Foundation Pit can be avoided, floor space is saved, training of channel amount during section floating is reduced, is reduced
Construction costs；
3rd, floor space and port basin amount can be reduced, construction costs is reduced, while the method is heavy suitable for all scales
Pipe tunnel.
