Assembled grade crossing

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...

AI Technical Summary

Problems solved by technology

[0006] Although the application of the rail row type railway crossing has overcome the shortcomings of the lack of integrity of the traditional railway crossing, due to the limitations of its own structural design, it still cannot overcome the various diseases of the outer crossing plate of the rails and the mud and mud of the road center.
