Description
Technical field
This utility model relates to a kind of bridge-turning construction equipment, and the underground bridge particularly relating to a kind of band safeguard structure turns
Body device.
Background technology
Bridge type and bridge layout, in addition to meeting basic stress and the traffic capacity, are also had higher requirements by Bridge Design.Especially
It is Urban Bridge, as landmark, by society and government's extensive concern, in addition to cost of investment control, is also built
If place limits.When Longspan Bridge crosses over existing line, limited toward contact by bridge headroom and line slope etc..These because of
Number all has influence on the layout of bridge.Cost of investment is also the important factor controlling bridge type selecting, as attractive in appearance and reduction coagulation
Soil consumption by solid pier along bridge to perforate.Although having saved cost, also have impact on structure design.Sometimes bring the biggest to design
Trouble, due to super large Concentrated load during turning, for meeting structure bending resistance and shearing resistance requirement, is configured with more level
And vertical prestressing bar.Virtually increase structure design risk.
Utility model content
The purpose of this utility model be to provide a kind of compact in design, reasonable in design, can effectively reduce design risk and construction
The underground bridge rotating device of the band safeguard structure of cost.
The purpose of this utility model is achieved through the following technical solutions:
The underground bridge rotating device of band safeguard structure of the present utility model, including circular cushion cap, on described circular cushion cap
Side is provided with top rotary table and annular slide track, and described top rotary table is placed on annular slide track and is cut with scissors with described circular cushion cap by center hinge
Connecing, described top rotary table is placed bridge pier, described circular cushion cap and top rotary table are located at below ground, described circular cushion cap and top rotary table
Be provided around safeguard structure.
The technical scheme provided by above-mentioned this utility model is it can be seen that the band protection that this utility model embodiment provides is tied
The underground bridge rotating device of structure, compact in design, reasonable in design, can effectively reduce design risk and construction cost.

In figure: 1, safeguard structure；2, circular cushion cap；3, top rotary table；4, bridge pier；5, center hinge；6, pull strength counter-force seat；7、
Jack counter-force seat；8, temporary rest pier；9, hauling rope；10, supporting leg；11, notch.
Detailed description of the invention
This utility model embodiment will be described in further detail below.
The underground bridge rotating device of band safeguard structure of the present utility model, its preferably detailed description of the invention is:
Including circular cushion cap, described circular cushion cap is arranged over top rotary table and annular slide track, and described top rotary table is placed on ring
On shape slideway and hinged with described circular cushion cap by center hinge, described top rotary table places bridge pier, described circle cushion cap and upper
Below ground is located at by rotating disk, described circular cushion cap and top rotary table be provided around safeguard structure.
The outer rim of described top rotary table is wound with hauling rope, and described circular cushion cap is provided with traction counter-force seat, described hauling rope
Being connected with traction apparatus, described traction apparatus is against on described traction counter-force seat, and described safeguard structure has notch, described traction
The outer end of rope passes described notch.
Described circular cushion cap is provided with temporary rest pier, and the slideway edges of described circular cushion cap is provided with jack counter-force seat, institute
Stating and arrange crossbeam between jack counter-force seat, crossbeam is provided with boosting jack.
Described safeguard structure is diaphram wall or steel cofferdam structure.
Described bridge pier along bridge to having V-shape hole.
The underground bridge rotating device of band safeguard structure of the present utility model, cushion cap is embedded in underground certain depth, whole
Rotator construction completes at below ground completely, and topology layout is compact, reasonable in design, can effectively reduce design risk and building into
This.
Compared with prior art, this utility model is embedded in underground certain depth due to cushion cap, overcome line slope and
Headroom limits, and arranges for superstructure and bridge pier and design provides sufficient space, and cushion cap is arranged to circle simultaneously, draws counter-force
Move in seat, reduce cushion cap and arrange size, while reducing investment, make suspended deck structure stress the most reasonable.Cushion cap is embedded in simultaneously
Underground certain depth can also effectively reduce the settlement of foundation that neighbouring stress causes.
Specific embodiment:
Seeing shown in accompanying drawing 1, accompanying drawing 2, including safeguard structure 1 and rotor system, wherein safeguard structure 1 is diaphram wall
Or steel cofferdam structure.Rotor system includes top rotary table 3, center hinge 5, pull strength counter-force seat 6, and cushion cap 2, hauling rope 9, jack are anti-
Power seat 7, temporary rest pier 8, supporting leg 10；At cushion cap 2 end face, annular slide track is set as lower rotary table.
Continuous jack traction hauling rope 9 is used to form rotation couple, simultaneously at jack counter-force seat 7 during rotator construction
It is arranged in pairs boosting jack, overcomes the couple that stiction is formed with kinetic force of friction difference.Along with hauling rope 9 traction end not
Disconnected elongation, hauling rope 9 is by the notch 11 through enclosed structure 1, if enclosed structure is not slotted, needs constantly to cut hauling rope.Turn
After completing, rotating disk is carried out sealing and foundation ditch has backfilled and had suffered construction.
Seeing shown in accompanying drawing 1, this utility model embodiment provides one to be used for underground bridge rotating and guard system structure,
After moving down due to cushion cap 2, arrange for bridge pier 4 and provide enough spaces, bridge pier 4 can be designed according to actual needs, such as Fig. 1 institute
Show, in order to handsome in appearance, reduce concrete amount by bridge pier along bridge to opening " V " hole, owing to there being enough spaces to reduce bridge pier
