Abstract
The utility model relates to an integral road bed that can be prevented from being pressed in the soft laneway soleplate, and is realized by increasing the width and reducing the pressure of the road bed on the laneway soleplate. The integral road bed is prefabricated by the concrete; a plurality of inherent stress reinforced bar and threaded reinforced bar hoops are arranged inside the integral road bed to improve the strength of the road bed. The road bed is provided with longitudinal central holes to reduce the weight of the road bed and to be used as the water flowing passages. Tow track-fixer substrates are pre-arranged on the upper panel of the road bed according to the requirements of the track distance, and the substrate is provided with a track fixer base. A track fixer spring that is used for the railway steel track is fixed on the track fixer base of the integral road bed, so as to complete the pavement of the track.
Description
Affiliated technical field
The utility model relates to a kind of novel railway roadbed of coal mine narrow gauge railway, especially is fit to the soft tunnel of base plate and lays 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.
The utility model content
Be pressed into base plate and maintenance difficult in order to overcome the soft tunnel of base plate track, it is a kind of coal mine narrow gauge railway monolithic road-bed that the utility model provides, 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 scheme that its technical problem that solves the utility model adopts 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 beneficial effects of the utility model are:
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)
1. 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 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 of railway gauge requirement (4), and railway track (6) is fixed on the solid track device base (5) of railway roadbed with solid track device spring (8).
