Abstract
The utility model relates to a kind of Railway Bridges And Piers, and deck type to be added to encircle anti-fall stone structure, in the longitudinally disposed deck type arch structure in top of the pier coping portion two sides widened section below railway beam, deck type arch structure includes the arc arch rib of two sides longitudinal direction, perpendicular support is provided with above arch rib, perpendicular support top and horizontal stringer consolidate, and are connected the horizontal girder (10) on top by the stull of horizontal cross；Supple buffer layer is laid with above stull.The utility model can be carried out the falling rocks rolled down on steep hill and effectively protect, and prevents falling rocks from invading railway clearance, impacts to traffic safety.
Description
Technical field
The utility model belongs to bridge structure technical field of buildings, and in particular to a kind of Railway Bridges And Piers add deck type arch anti-fall
Stone structure.
Background technique
Rockfall disaster is one of big geological disaster in China three, is a kind of common geology of narrow valley region and cliffy mountain
Disasters Type, in its damaging range structures and mankind's activity constitute and seriously threaten.
China's high-speed rail is widely distributed, and Built Projects are predominantly located at plains region, 13 railways planning in it is large quantities of in
Railways in West China is typical mountain area high-speed rail.Mountain area high-speed rail is influenced seriously by falling rocks, the precipitous V-arrangement ditch region in mountain area, for mountain area
High-speed rail " two tunnels press from both sides a bridge ", bridge is about this engineering type of 100m, currently without particularly suitable rock-fall protection type.Mountain
The bottleneck that area's high-speed rail rock-fall protection develops at constraint China's high-speed rail.
Need to study novel protectiving scheme at present for this engineering model, breakthrough bottleneck, China's high-speed rail could be more preferable
Popularization in the world.
Summary of the invention
The purpose of the utility model is to provide a kind of Railway Bridges And Piers, and deck type to be added to encircle anti-fall stone structure, to rolling on steep hill
Under falling rocks protected, prevent falling rocks invade railway clearance, traffic safety is impacted.
The technology employed by the present utility model is
A kind of Railway Bridges And Piers add deck type to encircle anti-fall stone structure, it is characterised in that:
The longitudinally disposed deck type arch structure in top of pier coping portion two sides widened section below railway beam, deck type arch
Structure includes the arc arch rib of two sides longitudinal direction, is provided with perpendicular support above arch rib, erects support top and horizontal stringer consolidates, pass through water
Lateral stull is put down to connect the horizontal girder on top；
Supple buffer layer is laid with above stull.
One layer of steel plate is equipped between supple buffer layer above stull.
Perpendicular support is flushed with supple buffer layer top surface, and entire deck type arch structure cross section is in shaped door.
Pier coping portion is fixed on by pedestal in arch rib longitudinal direction both ends bottom.
The utility model has the advantage that
(1) handsome in appearance:
General Simple Supported Railway Bridges moulding is single, and deck type arch structure is added on Railway Bridges And Piers, is made
Type is beautiful, is equivalent to and has made an arch appearance finishing to common simply supported girder bridge.
(2) reduce basis to interfere with each other:
Railway Bridges And Piers basis is larger, and when safeguard structure basis is near Railway Bridges And Piers basis, plan-position is difficult to put, and applies
Work interferes with each other.It being made into Railway Bridges And Piers deck type and encircles anti-fall stone structure, safeguard structure lower part is directly combined into one with pier footing,
It does not need to consider further that plan positional relationship.
(3) it reduces and lower space is occupied:
When bridge pier and safeguard structure lower part pier stud arranged apart, space under bridge is limited, by bridge pier
And the compression of protection pier stud, necessarily affect the flood passage cross-section of river and grade separation space under bridge.By bridge pier and safeguard structure
Merge and consider, reduces and space under bridge is occupied, improve flood discharge capacity and grade separation ability.
(4) overall stability is strong:
Two of top longitudinal deck type arch structures are laterally after consolidation, it is similar with by two arch bridge cross
To consolidation, basis is located on the Railway Bridges And Piers of lower part.Top overall stiffness is big, and stability is strong.
Detailed description of the invention
Fig. 1 is the utility model cross-sectional view.
Fig. 2 is the utility model skiagraph.
In figure, 1- deck type arch structure, 2- railway beam, 3- bridge pier, 4- stull, 5- steel plate, 6- supple buffer layer, 7- arch
Rib, the perpendicular support of 8-, 9- cushion cap, 10- stringer.
Specific embodiment
The utility model is described in detail With reference to embodiment.
The utility model relates to a kind of Railway Bridges And Piers, and deck type to be added to encircle anti-fall stone structure, and design principle is using on two
The structure sheaf and buffer layer for holding lateral consolidation rod piece and top between formula arch structure stringer form one on railway clearance
Roof structure, the falling rocks in side slope are stopped by top " roof ", can not invade railway clearance.
The structure is in the longitudinally disposed deck type arch knot in the top of the 3 top two sides widened section of bridge pier of 2 lower section of railway beam
Structure 1, deck type arch structure 1 include the arc arch rib 7 of two sides longitudinal direction, are provided with above arch rib 7 and erect support 8, erect 8 tops of support and level
Stringer 10 consolidate, the horizontal girder 10 on top is connected by the stull 4 of horizontal cross；It is laid above stull 4 flexible slow
Layer 6 is rushed, buffer layer can add the mode of spring with double-layer plate.One layer of steel plate is equipped between 4 top of stull and supple buffer layer 6
5。
Perpendicular 8 top of support is flushed with 6 top surface of supple buffer layer, and entire 1 cross section of deck type arch structure is in shaped door.Arch rib 7 is vertical
3 top of bridge pier is fixed on by pedestal to both ends bottom.
When construction:
Construct pier footing, after the completion of pier footing, construction widen after Railway Bridges And Piers 3, set up railway beam 2.
It is constructed respectively two deck type arch structures 3 using the platform of railway beam 2 in pier coping portion arranged on left and right sides, it can also will
Deck type arch structure 3 is lifted at the top of Railway Bridges And Piers again after the completion of ground construction.The top of deck type arch structure 3 needs to be higher than iron
Road limit.
Support 8 is erected at the top of deck type arch structure 3 laterally to consolidate by stull 4, makes shape after two arch structures transverse direction consolidations
At an overall structure.
It is laid with steel plate 5 in stull 4, is laid with supple buffer layer 6 on 5 top of steel plate.
The utility model relates to structure can effectively prevent falling rocks intrusion railway clearance, Railway Bridges And Piers basis and safeguard structure
Basic " being combined into one ", reduces and occupies lower space, handsome in appearance.Especially in precipitous " V " shape ditch region, two tunnels
A minibridge location is pressed from both sides, rock-fall protection is carried out and has a clear superiority.
The content of the utility model is not limited to cited by embodiment, and those of ordinary skill in the art are practical new by reading this
Type specification and to any equivalent transformation that technical solutions of the utility model are taken, be the claim institute of the utility model
Cover.
