Abstract
The invention relates to an integral ballast bed which can prevent loose and soft roadway floor from being pressed, the integrated ballast bed is realized by increasing width and reducing the load intensity of ballast bed on the roadway floor. The integral ballast bed is premade by concrete, the built-in pre-stressed steel bars and the threaded steel bar hoops are used to improve the strength of the ballast bed. The ballast bed is vertically provided with a central hollow cavity so as to reduce the weight of the ballast bed and is also used as a water flowing channel. The upper plate surface of the ballast bed is premade with two rail fixer pedestals according to the requirement of the gauge, the rail fixer pedestals are pre-buried with rail fixer bases. The railway rail is arranged fixedly on the rail fixer bases of the integral ballast bed by rail fixer springs, thereby finishing the paving of railway.
Description
Affiliated technical field
The present invention relates to a kind of novel railway roadbed of coal mine narrow gauge railway, especially be fit to the soft tunnel of base plate and lay a railway track.
Background technology
The laying of coal mine narrow gauge railway is railway ballast and a regular sleeper on the roadway floor upper berth at present, with railway spike rail is fixed on the sleeper then.Track needs often maintenance.Particularly in the soft tunnel of base plate, sleeper often is pressed into base plate, needs often maintenance.Influence traffic safety.
Summary of the invention
Be pressed into base plate and maintenance difficult in order to overcome the soft tunnel of base plate track, the invention provides a kind of coal mine narrow gauge railway monolithic road-bed, because this railway roadbed increases several times than original sleeper area, so not only can prevent that railway roadbed is pressed into roadway floor, and can directly railway roadbed be laid on the roadway floor, avoid using railway ballast.
The technical solution adopted for the present invention to solve the technical problems is: coal mine narrow gauge railway monolithic road-bed is to form with concrete prefabricated, and its length keeps original size, and its width is increased to the several times of former sleeper, and its area has also increased several times.Arrange vertically that along solid concrete roabed several cavities, center can alleviate railway roadbed weight.Railway roadbed adopts the longitudinal prestressing reinforcing bar, laterally adopts indented bars to prick hoop.Press the prefabricated two solid track device pedestals of railway gauge at the railway roadbed upper face, the solid track device base is embedded on the pedestal.Rail is fixed on the solid track device base of railway roadbed with the solid track device spring.When laying a railway track, no longer stay the gap between railway roadbed and the railway roadbed.
Beneficial effect
The invention has the beneficial effects as follows:
1, because the railway roadbed area increases, and railway roadbed reduces the specific pressure of roadway floor, the possibility that railway roadbed is pressed into roadway floor reduces.So the track maintenance reduces.
2, railway roadbed is laid on the roadway floor, avoids using railway ballast.Solid concrete roabed is paved with roadway floor, and the tunnel health is clean and tidy.
3, railway roadbed is provided with the longitudinal center cavity, and a gang of trickle in tunnel can flow in the ditch of tunnel opposite side along the cavity, center.

The specific embodiment
Solid concrete roabed 1 is concrete prefabricated forming among the figure, has made cavity, center 2 in the railway roadbed 1 alleviating the weight of railway roadbed, and has been used for flowing water.Railway roadbed vertically adopts prestressed reinforcement 3 to improve the longitudinal strength of railway roadbed; Laterally adopt indented bars to prick the transverse strength that hoop 7 improves railway roadbed.The upper face of railway roadbed 1 is used for pre-buried solid track device base 5 by the prefabricated two solid track device pedestals 4 of railway gauge requirement.Railway track 6 usefulness solid track device springs 8 are fixed on the solid track device base 5 of railway roadbed.When laying a railway track, no longer stay the gap between railway roadbed and the railway roadbed.
Claims (1)
- A kind of solid concrete roabed made from concrete, it is characterized in that: solid concrete roabed 1 is to form with concrete prefabricated, the more original sleeper width of width of ballast bed increases several times, railway roadbed and railway roadbed are when laying, no longer stay the gap, made cavity, center 2 in the railway roadbed 1 alleviating the weight of railway roadbed, and be used for flowing water, railway roadbed vertically adopts prestressed reinforcement 3 to improve the longitudinal strength of railway roadbeds; Laterally adopt indented bars to prick the transverse strength that hoop 7 improves railway roadbed, the upper face of railway roadbed 1 is used for pre-buried solid track device base 5 by the prefabricated two solid track device pedestals 4 of railway gauge requirement, and railway track 6 usefulness solid track device springs 8 are fixed on the solid track device base 5 of railway roadbed.
