Example Embodiment

[0021] Hereinafter, an assembled level crossing as an example of the present invention will be described based on the drawings.

[0022] figure 1 It is a schematic cross-sectional view showing the assembled level crossing of the present invention.

[0023] Such as figure 1 As shown, the assembled level crossing of the present invention has a graded gravel layer 10, a monolithic track bed 20, and a track 30.

[0024] The graded gravel layer 10 is laid on the foundation of the crossing. The monolithic track bed 20 is arranged on the graded crushed stone layer 10, and two rail installation grooves 21 are formed on the upper surface of the monolithic track bed 20. The rail 30 is installed in the groove 21 for rail installation.

[0025] When constructing such a level crossing, as long as the monolithic track bed prefabricated block is hoisted on the graded gravel layer, the line is laid, and the cement mortar is used for grouting, and finally the road surface on both sides of the cross...

Abstract

The invention provides an assembled grade crossing with compact structure, good integrity, stress uniformity, simplicity in construction, long maintenance cycle and low maintenance cost. The assembled grade crossing comprises a graded broken stone layer, an integral road bed and a track, wherein the graded broken stone layer is laid on a foundation of the railroad grade crossing; the integral road bed is arranged on the graded broken stone layer, and two grooves used for mounting the track are formed in the upper surface of the integral road bed; and the track is mounted in the grooves used for mounting the track. The assembled grade crossing is simple to construct, construction speed is high, construction time is shortened, normal traffic can be restored in the shortest time, and construction cost is reduced; meanwhile, the problems that a circuit is hung on a plate, mud pumping is caused and a grade crossing plate is broken can be solved.

Description

technical field [0001] The invention relates to a level crossing, in particular to an assembled level crossing. Background technique [0002] A level crossing is a crossing at the intersection of a railway and a highway. It is often used when the traffic volume is not large, or when there is no condition to set a three-dimensional intersection, especially in large ports. And in such a large port, the railway and road transportation are very busy, and the railway level crossing as the necessary passage for the railway and the road is the throat and the weakest link of the railway and road transportation. [0003] At present, level crossings mainly have two forms: typical traditional railway crossings and rail row railway crossings. The laying method of a typical traditional railway crossing is as follows: wooden sleepers are laid on the track bed at a distance of 0.5m, and steel rails and wooden sleepers are connected with spikes. Fill the ballast between the wooden sleeper...
