Description
Technical field
The present invention relates to rail traffic, in particular to elastic long sleeper buried-type non-fragment orbit structure on a kind of Railway Steel Truss Girder Bridges
It makes.
Background technique
High-speed railway steel truss girder bridge, frequently with Concrete Composite Beam bridge floor or Orthotropic steel plate.Under normal circumstances,
The track structure of Railway Steel Truss Girder Bridges mainly has sleeper open bridge floors, synthetic resin track, Ballast track etc., however sleeper durability
Poor, structural life-time is short；Synthetic resin sleeper cost is higher, is not suitable for extensive be laid with；Maintenance, maintenance of Ballast track etc. have
Mature experience is used for reference, but bridge deck is covered by railway ballast, is not easy maintenance and inspection, and Ballast track self weight is larger, easily causes steel
Truss bridge deformation aggravation.
To meet high-speed railway to high smooth, high stability requirement, engineers and technicians are had developed applied to rail iron
The non-fragment orbit of truss bridge is exactly the most typically plate-type ballastless track.It is practical new such as patent No. ZL201220431923.9
A kind of Railway Steel Truss Girder Bridges non-fragment orbit laying construction is disclosed in type patent specification, and track plates are directly placed on bridge and are indulged
Liang Shang, and connect track plates with bridge stringer by connecting bolt；The utility model of patent No. ZL201220431890.8 is special
A kind of Railway Steel Truss Girder Bridges non-fragment orbit laying construction is disclosed in sharp specification, and track plates are directly placed on bridge and are indulged
The vertically and horizontally displacement that limit component limits track plates is arranged by the surrounding in track plates in Liang Shang.Although two kinds of plate-type ballastless rails
Road structure is simple, but track plates are directly placed on bridge stringer, is equivalent to track plates and is laterally in both ends letter bearing state, right
Track plates itself stress is unfavorable.One kind is then disclosed in the utility model patent specification of patent No. ZL201320538967.6
It is longitudinally continuous spacing-type non-fragment orbit on steel truss girder bridge, is directly to pour the track plates of piecemeal on steel truss girder bridge panel, and set
It is equipped with and is longitudinally continuous position limiting structure.Since steel truss girder bridge has that vibration noise is big, it is easy access bridge bridge and track structure
Cracking, the ballastless track structure do not consider vibration and noise reducing measure.
Summary of the invention
Technical problem to be solved by the invention is to provide long sleeper buried-types elastic on a kind of Railway Steel Truss Girder Bridges without tiny fragments of stone, coal, etc. rail
Road structure reduces bridge secondary dead load, and have the function of vibration and noise reducing to effectively improve the globality and stability of track structure.
The technical solution adopted by the present invention to solve the technical problems is as follows:
Elastic long sleeper buried-type ballastless track structure on a kind of Railway Steel Truss Girder Bridges of the invention, including bridge stringer and length
Sleeper, it is characterized in that: installing fixed prefabricated bridge by installation component on the bridge stringer, scene is poured on prefabricated bridge
It builds concrete and forms cast-in-place road bed board, cast-in-place road bed board forms fixation by embedded connecting elements in the inner with prefabricated bridge
Connection；The elastic packaging layer of lower part setting package its side wall and bottom surface of the long sleeper, and it is embedded in cast-in-place railway roadbed board concrete
It is interior.
The connecting elements is the frame reinforcing bar being arranged in column with longitudinal gap that is horizontally arranged at interval, under each frame reinforcing bar
Portion is embedded in prefabricated bridge concrete, and is fixedly connected with the arrangement of reinforcement of prefabricated bridge.
The invention has the advantages that eliminating the base plate of traditional long sleeper buried-type non-fragment orbit, no tiny fragments of stone, coal, etc. rail is reduced
The structure height in road and the secondary dead load of bridge；Cast-in-place road bed board is connect by frame reinforcing bar with prefabricated bridge, and iron is improved
The globality and stability of ballastless track structure on the steel truss girder bridge of road；Cast-in-place road bed board is connected by frame reinforcing bar and prefabricated bridge
It connects, improves the globality and stability of ballastless track structure on Railway Steel Truss Girder Bridges；Its side wall is wrapped up in long sleeper lower part setting
With the elastic packaging layer of bottom surface, the overall stiffness of non-fragment orbit can be reduced, and there is good effect of vibration and noise reduction, is also beneficial to
Guarantee the durability of substructure.
