Description
Technical field
The present invention relates to a kind of method of prefabricated immersed tube pipeline section in immersed tube tunnel, in particular to the immersed tube pipeline sections of box hat outsourcing
Floading condition production method.
Background technology
The prefabrication of tube section method of immersed tube tunnel decides the success or failure of entire engineering, currently, prefabrication of tube section in dry-docking into
Row, dry-docking scheme have 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 then refuted into dive in haul to the tunnel nearby basin built up using tugboat, realization pipeline section 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 pit
Water depth controls.Pipeline section is made in fixed dry-docking, dock gate is opened after the completion of tube manufacture, and pipeline section is hauled to tunnel location and is sunk
It puts.Fixed dry-docking is divided into builds several classes such as dry-docking, independent dry-docking for axis dry-docking, side.
Batch production dry-docking refers to carrying out technology arrangement according to continuous-flow type prefabricated production line, and all pre- manufacturings are 24 in workshop
Hour is carried out continuously, and each segment is after fixed pedestal upper, maintenance 3d, and pushing tow, vacates and pour pedestal forward, Xia Yijie
The segment neighbor of Duan Yugang ejections is prefabricated.So piecewise prefabricated piecewise pushing tow pours, whole top until completing whole segments
It is pushed into the interim prestressed cable tensioning of shallow depressed place progress and forms entirety, complete 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 Shen Wu, 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 suitble to Large-scale Super Long immersed tube tunnel（Or length can be obtained
The region that the pipeline section that phase stablizes is ordered）Prefabrication of tube section.The built port Zhuhai and Macao bridge of Oresund Bridge immersed tube tunnel and China
It is exactly to use batch production dry-docking.
Existing dry-docking scheme is primarily present following defect：
（1）Mobile dock is only applicable to 4 tracks and following situation, more than 4 tracks since pipeline section is larger, matches
Partly latent refute less, it is larger to rent the difficulty refuted of partly latent；
（2）Mobile dock needs to excavate deeper dive basin to make pipeline section and partly latent refute to detach, to navigation channel and environment
It is affected；
（3）Fixed dry-docking needs excavation Large Foundation Pit to carry out prefabricated tube section, and cost is higher and is affected to surrounding enviroment；
（4）Batch production dry-docking floor space is larger, and cost highest is only suitable for Large-scale Super Long immersed tube tunnel.
Therefore, it is necessary to be improved to the prior art.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of immersed tube pipeline section floading condition production method of box hat outsourcing, the party
Method floor space is smaller, avoids excavating on the bank, while reducing section floating waterway dredging amount, and is suitable for various scale immersed tube tunnels
Road.
The technical solution adopted in the present invention is：
A kind of immersed tube pipeline section floading condition production method of box hat outsourcing, which is characterized in that include the following steps：
（1）Smooth location, construction steel plate processing workshop, outfitting quay and slideway area, the steel plate processing workshop include cutting
Cut milling side workshop, sandblasting Painting Shop and sheet body assembling area；
（2）Inside welding ribbed stiffener and rivet after the cleaved milling side of steel plate, sandblasting application and sheet body assembling；
（3）The steel plate is positioned over and welds U-shaped in slideway area and welds temporary support；
（4）Each 3~4 meters of ranges in both ends pour tunneling boring concrete, and rest part pours bottom plate, whole mid-boards and lower part
3~4m side wall concretes；
（5）Both ends are installed by steel end housing, steel end seal wall and guider；
（6）Pipeline section is slid by jack and winch in water；
（7）The pipeline section is consigned to the remaining side wall of outfitting quay progress and concrete roof and is poured；
（8）The temporary support is removed, and water tank component is mounted on inner tube segment by post-cast strip and interim manhole；
（9）Post-cast strip concrete is poured, secondary fitting-out is carried out, section floating to designated position is subjected to sinking later.
Beneficial effects of the present invention are：
（1）The prefabrication of tube section method of the present invention is refuted compared with mobile dock without partly latent, and the excavation of dive basin is can avoid,
Therefore it can reduce influence to environment, reduce project cost, while not being refuted by partly latent and being restricted sinking suitable for all scales
Pipe tunnel.
（2）The prefabrication of tube section method of the present invention can avoid the excavation of Large Foundation Pit compared with fixed dry-docking, save occupation of land face
Product reduces training of channel amount during section floating, reduces project cost.
(3) present invention can reduce floor space and port basin amount compared with batch production dry-docking, reduce project cost, simultaneously
This method is suitable for all scale immersed tube tunnels.
