Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building block type easy assembly type railroad crossing that can be easily removed and restored at a railroad crossing where a railroad and a road intersect on the same plane.
[0002]
[Prior art]
The railroad crossing where the railroad and the road intersect on the same plane is a part of the road and part of the track, and the pavement has sufficient strength as a road surface and is removed for repair work of the track. Recovery must be easy. In order to secure the flange way of the wheel, the railroad crossings are provided with guard rails on the inner sides of the left and right rails, and the road surface and the rail surface are set at the same height. There are two types of railroad crossings: one that is small enough for people to pass, and one that allows vehicles to pass. The invention of the present application is intended for small-scale humanitarian crossings where only people can pass, and the conventional humanitarian crossings are of a wooden structure and those of asphalt pavement, as are large-scale ones that vehicles can pass through. Three types are common: concrete blocks. The level crossing of the wooden structure embeds the old sleeper (horizontal sleeper) in the same direction as the sleeper laid in the track, and lays the old sleeper (vertical sleeper) in the direction perpendicular to the embedded horizontal sleeper (same direction as the rail) The vertical sleepers are lined up and connected with the horizontal sleepers.
In addition, the railroad crossing of the concrete block is provided with a splint on the side in contact with the rail and the guard rail, and a block receiver is laid on the roadbed between them, and the concrete block is placed on the block receiver.
In addition, asphalt pavement crossings are provided with splints on the side in contact with the rails and guard rails, filled with crusher run in the gap between the pavement ballasts in the pavement between them, sprayed with asphalt emulsion and spread. Finished by fully rolling or compacting.
[0003]
[Problems to be solved by the invention]
However, the wooden structure of the humanitarian level crossing has a drawback in that the nail hole connecting the vertical sleeper and the horizontal sleeper becomes large by repeating the removal and restoration operations two to three times, and it becomes impossible to connect the sleepers with the nail. there were. That is, there is a drawback that the life of the sleeper used is short.
In addition, the concrete block humanitarian railroad crossing has the disadvantage that the splint portion has a large nail hole in the same manner as in the case of the wooden structure, so that the number of repeated use is limited and the life is short. Moreover, each concrete block is a heavy object exceeding 100 kg that cannot be transported unless one of the workers is a few workers, and has a disadvantage that it requires a lot of manpower and time to handle it.
In addition, humanitarian level crossings using asphalt pavement have the same problem of splint life as in the case of concrete block crossings, and if it is removed and restored, it is necessary to re-start asphalt pavement again. There was a drawback that it was a major restoration work.
In short, with these conventional humanitarian level crossings, it is difficult to remove and restore the level crossing when the road floor is hardened by multiple tie tampers or rails are replaced, and the life of the wood used is short. There were drawbacks. Further, the removal and restoration work requires a lot of manpower, time and cost, and there is a drawback that a quick restoration work cannot be realized continuously with the track maintenance work by the multiple tie tamper.
