Embodiment Construction

[0021] In the figure, the overall track bed 1 is prefabricated by concrete, and a central cavity 2 is set in the track bed 1 to reduce the weight of the track bed and be used for running water. The longitudinal strength of the ballast bed is improved by using prestressed steel bars 3 in the longitudinal direction; the transverse strength of the ballast bed is improved by using threaded steel bar tie hoops 7 in the horizontal direction. The upper surface of the ballast bed 1 is prefabricated with two rail-holding bases 4 for pre-embedding the rail-holding base 5 according to the railway gauge requirements. Railroad rail 6 is fixed on the rail-holding device base 5 of ballast bed with rail-holding device spring 8. When laying the track, there is no gap between the track bed and the track bed.

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

Technical field [0001] The invention relates to a novel ballast bed of a coal mine narrow-gauge railway, which is especially suitable for roadway track laying with soft floor. Background technique [0002] The laying of coal mine narrow-gauge railway is to spread ballast and common sleepers on the roadway floor at present, then rails are fixed on the sleepers with spikes. Tracks require frequent maintenance. Especially in roadways with soft floors, sleepers are often pressed into the floor and require frequent maintenance. Affect driving safety. Contents of the invention [0003] In order to overcome the difficulty of pressing the roadway rails into the floor of the soft roadway and maintenance, the present invention provides an integral ballast bed of narrow-gauge coal mine railways. Since the area of ​​the ballast bed is several times larger than that of the original sleeper, it can not only prevent the ballast bed from being pressed into the roadway floor, but also di...
