Description
Technical field
This utility model relates to bridge construction field, a kind of drag-line and the overpass encircleing combined system.
Background technology
Along with the continuous propelling of urbanization, the vehicle on road surface gets more and more, and traffic pressure increases day by day, more and more
City selects to build overpass.Overpass is typically built in the location that vehicle flowrate is big, pedestrian is dense, or crossing, wide
Above field and railway.Overpass only allows pedestrian to pass through, the conflict in time avoiding wagon flow and people's plane of flow to intersect, and ensures people
Safety pass through, improve speed, reduce vehicle accident.But the construction of overpass can run into situation about suspending traffic,
Work progress can bring no small pressure to road traffic.Overpass span requires the most increasing now, existing people
Row overline bridge span can not meet demand.And, it is the most attractive in appearance that existing overpass there is also external form, with the city of surrounding
Environment is incompatible with, and fabrication and installation cost is high, the problem of long construction period.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and provides a kind of drag-line and arch
The overpass of combined system, the overpass of this drag-line and arch combined system is in whole work progress, it is not necessary to suspend traffic,
Impact on traffic is little, can improve efficiency of construction, accelerates construction progress, reduces construction cost；And it is applicable to various version
Overpass, the suitability is wide.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
The overpass of a kind of drag-line and arch combined system, including being positioned at middle part and in horizontally disposed main bridge be arranged at
Two auxiliary bridges of main bridge both sides, host bridge is bowstring arch bridge, and each auxiliary bridge is provided with two Tower Column of A Cable Stayed Bridge；Each oblique pull
Bridge tower all includes a bridge tower being vertically arranged and three drag-lines, fixes with auxiliary bridge bridge plate or basis and be connected bottom bridge tower, every
One end of drag-line is fixing with bridge tower top to be connected, and the other end of every drag-line is fixing with auxiliary bridge bridge plate to be connected.
Two Tower Column of A Cable Stayed Bridge on each auxiliary bridge are followed successively by outer Tower Column of A Cable Stayed Bridge and interior Tower Column of A Cable Stayed Bridge, outer cable-stayed bridge from outside to inside
Tower includes a high post being vertically arranged and three root length drag-lines, interior Tower Column of A Cable Stayed Bridge include a low post being vertically arranged and three short
Drag-line.
Two outer Tower Column of A Cable Stayed Bridge are arranged symmetrically with about main bridge, and two interior Tower Column of A Cable Stayed Bridge are also arranged symmetrically with about main bridge.
The step of one auxiliary bridge is spiral terrace, and the step of another auxiliary bridge is vertical step.
After this utility model uses said structure, have the advantages that the People's Bank of China of above-mentioned drag-line and arch combined system
Overline bridge, uses drag-line to be connected with bridge plate by bridge tower, preferably coordinates mutually with surrounding, improve overall aesthetics；In construction
During, only need to set up enclosing, pretensioning drag-line at the two ends of auxiliary bridge, then bridge plate lifting is put in place, whole process is without interrupting
Traffic, the impact on traffic is the least, also improves efficiency of construction, accelerates construction progress, reduces construction cost；The present invention fits
For the overpass of various versions, the suitability is wide；And due to the existence of drag-line, can preferably help overpass to be subject to
Power, is conducive to developing the overpass of large span.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of drag-line of this utility model and the overpass of arch combined system.
Wherein have: the most main bridge；The most auxiliary bridge；Outer Tower Column of A Cable Stayed Bridge；31. Gao Zhu；32. long drag-lines；33. bases；4. oblique pull in
Bridge；41. low posts；42. short drag-lines.
Detailed description of the invention
With concrete better embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of drag-line and the overpass of arch combined system, including being positioned at middle part and in horizontally disposed master
Bridge 1 and two the auxiliary bridges 2 being arranged at main bridge both sides.
Above-mentioned main bridge uses bowstring arch bridge, can give full play to bowstring arch bridge self beam by curved, the advantage of arch pressurized.
Two Tower Column of A Cable Stayed Bridge, the bullet that Tower Column of A Cable Stayed Bridge is preferably vertically arranged it is provided with on each auxiliary bridge.
Each Tower Column of A Cable Stayed Bridge all includes a bridge tower being vertically arranged and three drag-lines, with auxiliary bridge bridge plate or base bottom bridge tower
Plinth is fixing to be connected, and one end of every drag-line is fixing with bridge tower top to be connected, and the other end of every drag-line is fixing with auxiliary bridge bridge plate even
Connect.
Two Tower Column of A Cable Stayed Bridge on each auxiliary bridge are followed successively by outer Tower Column of A Cable Stayed Bridge 3 and interior Tower Column of A Cable Stayed Bridge 4 from outside to inside.
Outer Tower Column of A Cable Stayed Bridge includes a high post being vertically arranged 31 and three root length drag-lines 32, high column bottom preferably be embedded in
The basis 33 of underground is fixing to be connected, and one end of every root length drag-line is fixing with high capital end to be connected, the other end of every root length drag-line and
Auxiliary bridge bridge plate is fixing to be connected.
Interior Tower Column of A Cable Stayed Bridge includes a low post being vertically arranged 41 and three short drag-lines 42, low column bottom preferably with auxiliary bridge bridge
Plate is fixing to be connected, and one end of every short drag-line is fixing with low capital end to be connected, and the other end of every short drag-line is solid with auxiliary bridge bridge plate
Fixed connection.
Two outer Tower Column of A Cable Stayed Bridge are arranged symmetrically with about main bridge, and two interior Tower Column of A Cable Stayed Bridge are also arranged symmetrically with about main bridge, thus
In picturesque disorder, more aesthetically pleasing.
One auxiliary bridge, preferably the step of the auxiliary bridge in left side is spiral terrace, another auxiliary bridge, and the preferably step of the auxiliary bridge in right side is
Vertically step.
Above-mentioned drag-line and the overpass encircleing combined system, work progress is as follows:
The first step, arranges enclosing: only need to arrange enclosing in the both sides of auxiliary bridge in overpass.
Second step, outer Tower Column of A Cable Stayed Bridge of constructing: first holding up two Gao Zhu, every high post is all by three root length drag-lines and People's Bank of China sky
Auxiliary bridge bridge plate in bridge is fixing to be connected.
3rd step, Tower Column of A Cable Stayed Bridge in construction: first holding up two low posts, every low post is all by three short drag-lines and People's Bank of China sky
Auxiliary bridge bridge plate in bridge is fixing to be connected.
4th step, main bridge of constructing: at main bridge portion, use the form of bowstring arch bridge, beam can be given full play to by curved, arch pressurized
Advantage.
In above-mentioned whole work progress, only enclosing need to be set in overpass both sides, and without suspending traffic, to current shadow
Ring the least；Due to the existence of drag-line, the more preferable stress of overpass can be helped, be conducive to developing the overpass of large span.
Preferred implementation of the present utility model described in detail above, but, this utility model is not limited to above-mentioned reality
Execute the detail in mode, in technology concept of the present utility model, the technical solution of the utility model can be entered
