Description
Technical field
The invention belongs to arch bridge technical field, and in particular to a kind of using foam concrete and the arch bridge structure of corrugated steel
And its construction method.
Background technology
During road and rail is built at home, jackshaft, foot bridge and culvert occupy larger ratio, and Material bridge and culvert design
The middle overwhelming majority uses armored concrete or masonry structure.Armored concrete or masonry structure, quantity of masonry is big, cumbersome, work of constructing
Phase is grown.Under the geological conditions of complexity, basement process, foundation engineering and quantities shared by substructure are larger, constructional difficulties.One
A little Structure adaptation foundation deformation abilities and anti-seismic performance are generally poor, when inhomogeneous deformation occurs in ground, can be produced in structure
Raw larger stress；If stress exceedes the strength of materials, cracking and the destruction of concrete structure will be caused, influence the work(of works
Energy and life-span, maintenance cost are huge.Arcuately the major bearing structures of bridge are arch ring.Because the horizontal thrust of arch springing both sides acts on,
Significantly reduce the moment of flexure in the arch ring caused by load.But traditional barnacle arch bridge, engineering quantity is huge, and to stone material
Quality, foundation bearing capacity and workmen's skill set requirements are higher, and common full hall formula support system is to the demand of circulation material
Also it is bigger.
Corrugated Steel Bridge and Culvert technology at home at present or a new field.Compared with other materials prefabrication, ripple
Steel plate have section it is small, it is flexible, in light weight, be easy to deposit and transport, construction technology is simple, assembling is quick, the construction period is short
The advantages that, it is a kind of novel product in bridge construction with larger promotion potential.Currently, corrugated steel structure is in medium and small arch
The research applied in bridge just starts to walk.The earthing steel ripple slab bridge largest spans few in number that corrugated steel product is built are not
More than 10m.For example, the Chinese invention patent of Application No. 201310220380.5 discloses a kind of skene arch steel corrugated plating bridges and culverts
Structure, single hole span are only 4m.Often rolled steel dosage is more for earthing steel ripple slab bridge, and bridge deadweight is larger.
To increase the span ability of structure, expanding corrugated steel product use range, dead load of being banketed on arch is further reduced
Deadweight, the strength and stiffness of the raising naked arch of corrugated steel are very crucial.The China of Application No. 201320127712.0 is real
Two layers of corrugated steel make-up connection inside and outside a kind of use, the combined type ripple of inner space filling resistance to compression filler are disclosed with new
Line steel plate arch bridge method of construction.Application No. 201310079450.X Chinese invention patent discloses a kind of open web type greatly across filling out
The composite corrugated steel plate arch bridge structure of soil, the combining structure use the composite corrugated steel plate of sandwich mortar, corrugated steel across main arch ring greatly
It is bolted into invert doubling plate and set peg to fill high-strength mortar in interlayer and forms overall sandwich mortar complex wave
Line steel plate, gastropore use corrugated steel tube, and load is transmitted by banketing between main arch ring and gastropore.
For long-span arch bridge, it is necessary to which arch ring has higher bearing capacity, particularly, rank is compacted in vault gravel pack
Section is, it is necessary to which arch ring has stronger anti-buckling failure ability.Above-mentioned patent proposes to be connected by inside and outside two layers of corrugated steel make-up
Connect and internally the enhancing structure bearing capacity measures such as resistance to compression filler are filled in space.In fact, corrugated steel arch ring is carried
Power enhancing effect is extremely limited, and technique is relatively complicated, and slip casting filling quality is not easy to detect and controlled, and corrugated steel spillage is asked
Topic is not easy to solve.

System, it is intended to spread traffic load stress by laying wing plate beam at the top of arch shell, prevent steel plate from encircleing shell unstability.But due to general
The load that the embankment bottom ground that logical sandstone material fills is born is far above arch shell bottom ground bearing load, serious road-bridge
Relative settlement frequently results in wing plate and disengaging of banketing below, and then wing plate occurs and come to nothing and fracture disease, and using effect is simultaneously
It is undesirable.
Masonry arch bridge main arch ring is shaped form, and generally vehicle can not be travelled directly in cambered surface, so driving a vehicle
The filler for transmitting load is needed between road system and main arch ring.Gathered materials on the spot to reduce cost, it is generally use gravel, broken
Stone, rough sand or cobble folder clay are simultaneously tamped；When filler not easy to drawing materials, often use instead and build formula spandrel construction by laying bricks or stones, generally adopt
By the use of dry-laid masonry or plain concrete is poured as arch fill.Above-mentioned traditional arch fill apparent density is generally 1800~
2450kg/m3, arch ring internal force is larger, is unfavorable for the stress of structure.If using the not good enough cohesive soil filler of water penetration, water penetrates into
Arch fill deadweight increase afterwards, reduce the ability of the vehicle load of arch bridge；The caused bulbs of pressure are normal after water content increase
Often result in side wall and pavement cracking；And seep water and flow to main arch ring, cause steel bar corrosion at crack, weaken area of reinforcement；Steel
Expanded after muscle corrosion, cause concrete scaling, have a strong impact on the bearing capacity and useful life longevity of arch bridge.Application No.
