Abstract
The present invention relates to a kind of anti-fall stone structures of trough girder composite roof truss, including trough girder, steel truss girder, cross-brace and steel grating；Vertical longitudinal steel truss girder is set above the floor of trough girder two sides, cross-brace is set between two sides steel truss girder top, laying steel grating above cross-brace, trough girder, steel truss girder, cross-brace and steel grating composition cross section are in the protective zone of rectangular frame shape.The present invention can effectively prevent the falling rocks intrusion railway clearance of precipitous Canyon Area, and construction is simple is easy, provides effective guarantee for operation security.
Description
Technical field
The invention belongs to bridge structure technical field of buildings, and in particular to a kind of anti-fall stone structure of trough girder composite roof truss.
Background technique
Rockfall disaster is one of geological disaster, is a kind of common geological disaster class of narrow valley region and cliffy mountain
Type, in its damaging range structures and mankind's activity constitute and seriously threaten.
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
It is about this engineering type of 100m, currently without particularly suitable rock-fall protection type.Mountain area high-speed rail rock-fall protection is at beam
Tie up the bottleneck of China's high-speed rail development.
Summary of the invention
The object of the present invention is to provide a kind of anti-fall stone structures of trough girder composite roof truss, to the falling rocks rolled down on steep hill
It is protected, prevents falling rocks from invading railway clearance, to ensure the operation security of train.
The technical scheme adopted by the invention is as follows:
The anti-fall stone structure of trough girder composite roof truss, it is characterised in that:
Including trough girder, steel truss girder, cross-brace and steel grating；
The vertical longitudinal steel truss girder of setting above the floor of trough girder two sides, cross-brace is arranged between top in two sides steel truss girder, horizontal
It is laid with steel grating to support top, trough girder, steel truss girder, cross-brace and steel grating composition cross section are in the anti-of rectangular frame shape
Protect space.
Buffer layer is equipped on steel grating.
Protective net is linked on the outside of steel truss girder.
Protection riser is added on the outside of steel truss girder.
The flexible hangar tunnel of arch is provided with above cross-brace, two side bottom of flexible hangar tunnel is fixed on cross-brace both ends.
The invention has the following advantages that
(1) project amount has been saved:
Top is higher from V-arrangement ditch bottom to safeguard structure, and safeguard structure lower part pier stud must have enough
Intensity can just support superstructure.The basis of the anti-fall stone structure of trough girder composite roof truss is acted on trough girder, no
With individually from ground construction pier stud basis, reducing overall engineering quantity again.
(2) reduce basis to interfere with each other:
General 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.After being made into the anti-fall stone structure of trough girder composite roof truss, safeguard structure is directly combined into one with pier footing, is not required 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.Bridge pier and safeguard structure are merged
Consider, reduces and space under bridge is occupied, improve flood discharge capacity and grade separation ability.
(4) stereoscopic protective structure:
Trough girder composite roof truss anti-fall stone structure can also add protection riser, the steel grating at top and two sides on the truss of two sides
Riser and the trough girder of bottom form a closed rectangular section, train passes through inside this rectangular section.Rectangle
Section not only can anti-top falling rocks, moreover it is possible to anti-arranged on left and right sides horizontally slungshot.Further enhance protection effect.
Detailed description of the invention
Fig. 1 is cross-sectional view of the present invention.
Fig. 2 is skiagraph of the present invention.
In figure: 1, trough girder, 2, steel grating, 3- steel truss girder, 4- cross-brace, 5- bridge pier, 6- flexible hangar tunnel.
Specific embodiment
The present invention will be described in detail With reference to embodiment.
The present invention relates to a kind of anti-fall stone structures of trough girder composite roof truss, including trough girder 1, steel truss girder 3, cross-brace 4
With steel grating 2.The vertical longitudinal steel truss girder 3 of setting above 1 two sides floor of trough girder, be linked on the outside of steel truss girder 3 protective net or
Add protection riser.Cross-brace 4 is set between 3 top of two sides steel truss girder, is laid with steel grating 2, steel grating above cross-brace 4
The buffer layers such as ageing-resistant rubber layer are equipped on 2.Trough girder 1, steel truss girder 3, cross-brace 4 and steel grating 2 form cross section
The protective zone of rectangular frame shape.The flexible hangar tunnel 6 of arch is provided with above cross-brace 4,6 liang of side bottoms of flexible hangar tunnel are fixed
In 4 both ends of cross-brace.
Design principle of the invention is to form a rectangular cross section, column using trough girder composite roof truss and the steel grating on top
Vehicle passes through inside rectangular cross section.Rectangular cross section can play protective action to the falling rocks of all directions around.
Work progress is:
1) it constructs behind bridge pier and basis, trough girder of constructing adds steel truss girder in trough girder floor, improves the structural strength of beam body；
2) cross-brace is added at the top of arranged on left and right sides steel truss girder, steel grating is added in cross-brace, is laid on steel grating slow
Rush layer；
3) protective net is hung on arranged on left and right sides steel truss, prevents the slungshot of two sides.
Structure of the present invention can effectively prevent falling rocks intrusion railway clearance, Railway Bridges And Piers basis and safeguard structure basis
" being combined into one ", reduces and occupies lower space, reduces system engineering amount.Especially in precipitous " V " shape ditch region,
Two tunnels press from both sides a minibridge location, carry out rock-fall protection and have a clear superiority.
The contents of the present invention are not limited to cited by embodiment, and those of ordinary skill in the art are by reading description of the invention
And to any equivalent transformation that technical solution of the present invention is taken, all are covered by the claims of the invention.
