DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simplified level crossing pavement installed at a level crossing where traffic on a road is relatively small.

[0002]

2. Description of the Related Art In a conventional level crossing, as shown in FIG. 4, a guard rail 3 is fastened inside a main rail 2 fastened to a wooden sleeper 1 to secure a flange way 4.
In general, a method of assembling wood 5, L-shaped steel 6, and concrete block 7 in the space of the remaining sleeper 1 and fixing it to the sleeper 1 to construct a pavement for a road is used.

[0003]

In a conventional level crossing, a wooden board, an L-shaped steel, a concrete block or a rubber block is disposed as a level crossing slab on a sleeper. Because there is no elastic material in between,
Most of the vehicle load is transmitted to the sleepers directly underneath, increasing the underside pressure of the sleepers directly under the load, resulting in the descent of the sleepers, which promotes the ups and downs of the tracks. is there. Also, since many pegs are used to fix the railroad crossing slab on the sleepers, a long track maintenance work time is required to remove and re-install the pegs during the track maintenance work time. Therefore, there is a demand for the development of a railroad crossing pavement plate which lowers the pressure of the lower surface of a sleeper, which is easy to remove and install a flooring plate, and which can be used for a concrete sleeper track.

[0004] In order to achieve the above-mentioned desires, a method of fastening a concrete paving board to a concrete sleeper, a method of adapting and cushioning a usual concrete sleeper and the bottom of a paving board, or a method of using a paving board within a gauge. Problems such as securing the flange way between the main line rail and the like must be solved.

[0005] In order to solve the above-mentioned problem, a special concrete sleeper having a top surface suitable for placing a pavement board and having a bolt hole for fastening a pavement board is designed. However, in this case, there is a problem that the design of the concrete sleeper becomes complicated and expensive, and the maintenance management becomes complicated.

[0006]
