Description
Technical field
The utility model is related to railroad track applied technical field, specifically provides a kind of combined embedded overall road
Bed.
Background technology
In the past when narrow gauge railway is laid in cities and towns, can only pass through its rolling stock, road in the range of railway line position
Vehicle cannot be using the plan-position in its railway line position；And track is using there is ballast bed, there is that land used is more, investment is big, profile
The cosmetic requirements in cities and towns can not be met.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of combined embedded solid concrete roabed, you can
Save the area, the requirement of aesthetic property in cities and towns can be significantly met again.
The utility model is achieved in that a kind of combined embedded solid concrete roabed of offer, including：
Bed course, is divided into sand folder cobble bottom, sand pad middle level and rubble upper strata；
Railway roadbed concrete layer, rail groove is surrounded by concrete-pouring template in the rubble upper strata, is poured in rail groove
Build and form；
Sleeper, is laid in the railway roadbed concrete layer；
Rail component, is provided with two groups, including rail, connection fastener, strong part and rubble overcoat, and rail is by the road
It is fixedly connected with the sleeper by connection fastener in the rail groove in bed concrete layer besieged city, the railway roadbed concrete of rail groove both sides
Pre-buried strong part in the sleeper of layer neutralization lower end, rail groove others space middle berths fill out metalling, and inner side rubble floor height
Degree be less than outside metalling, outside metalling, rail, railway roadbed concrete layer upper surface it is contour with ground.
Further, rubble upper thickness be 290-310mm, sand pad intima-media thickness be 240-260mm.
Further, track well width is that the distance between 1750mm, two rail inside edges are 762mm.
Further, strong part includes embedded bar and angle steel, in the railway roadbed concrete layer of the rail groove both sides, angle
Steel is pre-buried around the corner, and embedded bar oblique cutting since its adjacent angular is pre-buried, and welds together with angle steel；In the sleeper
In, embedded bar inserts pre-buried from rail groove both sides of the edge.
Further, metalling is divided into the pure metalling of lower floor and the bituminous macadam on upper strata.
Compared with prior art, the utility model has the advantage of nervous in land used condition, circuit (route) is through capable place
When required highway and public its plan-position of railway, the combined embedded solid concrete roabed provided with the utility model, tool
There are safety and stability, good appearance, save the area, reduce investment, shorten the duration.
Brief description of the drawings
Below in conjunction with the accompanying drawings and implementation method is described in further detail to the utility model：
Fig. 1 is the utility model cross-sectional view at sleeper；
Fig. 2 is A point mplifying structure schematic diagrams in Fig. 1；
Fig. 3 is the utility model bearing of trend structural representation.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with the accompanying drawings and implement
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model, is not used to limit the utility model.
Cannot be used to solve the problems, such as that railway takes up an area highway, the utility model provides a kind of combined embedded
Solid concrete roabed, with reference to Fig. 1, Fig. 2 and Fig. 3, including bed course, railway roadbed concrete layer 4, sleeper 6 and rail component, bed course is divided into sand folder
Cobble bottom 1, sand pad middle level 2 and rubble upper strata 3, are laid in railway foundation successively；Railway roadbed concrete layer 4 is by concreting
Template surrounds rail groove in rubble upper strata 3, is poured in rail groove and formed；Sleeper 6 is laid in railway roadbed concrete layer 4；Iron
Rail assembly is provided with two groups, including rail 7, connection fastener 8, strong part 9 and rubble overcoat 10, and rail 7 is by railway roadbed concrete
It is fixedly connected with sleeper 6 by connection fastener 8 in the rail groove that layer 4 is surrounded, in the railway roadbed concrete layer 4 of rail groove both sides with
Pre-buried strong part 9 in the sleeper 6 at end, rail groove others space middle berth fills out metalling 10, and inner side Ballast Layer Height less than outer
Side metalling, outside metalling, rail, railway roadbed concrete layer upper surface it is contour with ground.
When the combined embedded solid concrete roabed that the utility model is provided is laid, first online curb line is by railway foundation
Dig, 3 layers of bed course are laid successively, then erect concreting masterplate, first pour the concrete layer of sleeper bottom, then lay
Sleeper, then the concrete on upper strata is poured, after rail is laid after intensity scale, rail is fixed with sleeper by connection fastener, will be strong
After part position is fixed, then this pours railway roadbed concrete layer, and finally rubble overcoat is completed.
In order to form strong support to track, prevent from rolling repeatedly and cause rail to be recessed, as changing for technical scheme
Enter, rubble upper thickness is 290-310mm, sand pad intima-media thickness is 240-260mm, sand folder cobble underlayer thickness need to be according to geology
Situation and maximum frozen depth determine its thickness.
The utility model is applied to narrow gauge track applied technical field, as a kind of perferred technical scheme, track well width
For the distance between 1750mm, two rail inside edges are 762mm.
As one kind preferably, strong part 9 includes embedded bar 91 and angle steel 92, in the railway roadbed concrete layer of rail groove both sides
In 4, angle steel 92 is pre-buried around the corner, and the oblique cutting since its adjacent angular of embedded bar 91 is pre-buried, and welds together with angle steel 91；
In sleeper 6, embedded bar 91 inserts pre-buried from the groove both sides of the edge of rail 7.
Used as the improvement of technical scheme, metalling is divided into the pure metalling 11 of lower floor and the bituminous macadam 12 on upper strata.
