Description
The present invention relates to a kind of System and method for for realizing submerged floating tunnel, which hangs made of armored concrete
Floating parallelepiped module is polymerized.These modules form a monomer by the special wirerope of interspersed, drawing and are gathered
It is combined into an entirety, these wireropes pass through entire tunnel and are classified as independent section, and enter the sheath being arranged in module wall
Interior, by extracting out and locking in the position, wirerope compresses the structure to enhance its durability.Wirerope can be along the vertical and horizontal directions
It places.This method and existing system are further characterized in that tunnel quota will not change with tide and its load born.In order to
Different continent parts is connected, is for the demand of the floated tunnel even immersed tube tunnel of middle and high depth at present
Greatly.Modular system in the prior art is by cylindrical tunnel construction sections polymerization, is solidified togather to realize submerged floating tunnel.
Currently used scheme is to be based on: tunnel module is tunnel duct piece, and wherein the section of tunnel wall is solid or by one group
Solid non-suspending module condenses together to form tunnel construction sections, and the tunnel construction sections of the two are formed by solid wall, and very heavy, this is right
The suspension in tunnel is clearly unfavorable, it is therefore desirable to which the additional floating body of external application reaches enough suspension thrust in tunnel construction sections.This
The system and method for invention form tunnel wall by using hollow, single floated module to overcome these defects.By the group
Module combines to form tunnel construction sections, and this tunnel construction sections no longer have solid wall, and weight is extremely light, can make tunnel without additional floating body
Road floats.Since under the action of a large amount of bone ribs, the tunnel change in wall that hollow mold block is combined together to form is firm, and tunnel wall
Inside has partition, to increase durability, while making the average weight of total, therefore this tunnel is extremely light and resistance to
With.Tunnel module uses the reinforced concrete structure with conventional rebar, in conjunction with method are as follows: will " big reach " steel bar, press afterwards
Wirerope is inserted into appropriate sheath, is tensed and is locked, and being subsequently injected into cement mortar solidifies sheath and wirerope.The invention also achieves
Tunnel quota does not change this advantage with overload and tide, implementation are as follows: submerges the module section for constituting tunnel, makes
It sinks down into aequum, and then, after anchor hawser is fastened on seabed, the water that emptying module is accumulated more pushes away to generate
Power floats it, further that connection component is firm on seabed, and fighting pretension can, institute is loaded, and such as: ocean current generates
Load.Yet another advantage of the present invention is that the speed of tunnel assembling is identical as prefabricated and sea-freight speed.
According to the present invention, tunnel is realized in horizontal plane and/or underwater suspension, to address on realizing by a system
Other purposes.The system features are, the composition side in tunnel by it is one group of independent levitation, interior it is empty, can be connected together to form it is close
The module 4 for sealing tunnel construction sections forms.Tunnel is independent levitation, and without other floating bodies or block, tunnel is by one group 4 groups of suspending module
At, wherein the connecting side between module 4 connected has seal sand slurry.Module 4 is by bolt connecting type reinforcing bar and after tensing
It compresses wirerope 1 afterwards and wirerope 2 connects into an entirety, these modules 4 are parallelepiped shape, and are connected in its side
It connects；These modules 4 are reinforced concrete structure, at least one internal armored concrete partition 20；Constitute the module 4 in tunnel
With post-tensioning wirerope 1 and wirerope 2；The rear compression wirerope of module is fixed in the sheath 9 in the upper and lower region of module wall；This
A little sheaths are perpendicular to the contact wall of module 4 and in conjunction with wall；The upper and lower region of partition 20 in module is also equally to be arranged；After press
Contracting wirerope 1 and wirerope 2 pass through module 4, and so on to all modules, to form tunnel；Wirerope 1,2 vertically 21,
22 settings, the rear wirerope 1,2 that compresses are in tensioning state；The rear compression wirerope 1,2 of tensioning is in entire tunnel internal, the two and its
It is connected between related sheath with cement mortar, so that wirerope 1,2 and sheath 9 be connected, tunnel is anchored on seabed 12, and
Counterweight 13 is lain in rope or chain 14 or is anchored on the foundation pile in seabed 12, or is lain on the basis of the integral type of seabed；Tunnel phase
For the line that normally floats submergence amount at least equal under the influence of acting on the peak load in tunnel being applied, its sinking
Maximum tide offset.
Target of the present invention is to realize that this method is characterized in by a kind of method of achievable submerged floating tunnel, first can anchor
Gu the counterweight in tunnel is fixed on seabed, or builds foundation pile or the basis that can anchor tunnel on seabed, next, reinforcing bar is mixed
It is that solidifying soil is constituted, with parallelepiped shape and at least with the longer sides of the first suspending module of one piece of internal partition sealing and the
Two modules connect, and center line is aligned with the longer sides of the second module, are then bolted reinforcing bar occasional combination with appropriate
Get up, then repeatedly second stage, that is, increase more multimode and obtain the downside in tunnel, when these block combiners are at constituting under tunnel
When the number of modules of side, equal modules are anchored on seabed with wirerope or chain；Followed by by the way that post-tensioning wirerope is inserted into
It in the respective sheath in the upper and lower region of module and divider upright wall and is pulled, solidifies aggregation module.Wirerope is compressed by after
Along the insertion of vertical wall direction, the precompressed perpendicular to the long and short side of module, to form the downside of submerged floating tunnel, in post-tensioning wirerope and shield
Inner room injection cement mortar both makes to became one, and so that it is sunk down into right amount by aggregation module is partially submerged in next step, from
And it conveniently positioning, polymerizeing these modules to form the vertical wall in tunnel, while be tensioned the connection component in seabed again；With
Afterwards, the module for constituting Vertical tunnel wall and enhancing are placed and separates the potential partition of the tunnel construction sections of tunnel section, the module
Combination follow compact model after the combination on the downside of tunnel described in occasional combination model identical and previous steps, followed by
It realizes on the upside of tunnel, is interconnected to constitute on the upside of tunnel by module respectively, mode is the implementation pattern on the downside of above-mentioned tunnel；With
Tunnel downside and vertical edge, partition are sunk down into the correct depth apart from the water surface together afterwards, to be convenient to positioning, connection tunnel
On the upside of road.Meanwhile seabed connection component is tensioned again；Positioning on the upside of tunnel in Vertical tunnel wall with installation is connected by reinforcing bar
Realization is connect, the rear injection for compressing the interspersed of wirerope, drawing and mortar followed by submergence as previously mentioned, form on the upside of tunnel
