JP2001311104A - Road surface plate for road - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide road surface plates for road having a number of grooves (9) on their ourfaces and having holes, which are laid on the road and the snow can be automatically and compulsorily removed every time pedestrians and vehicles pass when snow is falling and accumulating. SOLUTION: The road surface plate (1) is to be laid on a structure (3) having a dent, arranged under the road surface. The road surface plate (1) has penetrating holes (2), in which the dimension of the hole in the back face is made larger than the hole in the top face.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for a road which can be forcibly cleared of snow naturally by laying a plate having a large number of holes on the surface thereof on a road at the time of snowfall, snowfall, or whenever a pedestrian or a vehicle passes. It is.

[0002]

2. Description of the Related Art Conventionally, a heating element is provided on a road surface, and electric power, groundwater is pumped up, and water is sprayed by a nozzle to melt snow on a snow-covered road. In addition, a special vehicle was driven to physically remove snow on the road surface. These are extremely dangerous for road managers, such as huge construction and maintenance costs, and slipping of pedestrians and running vehicles.

[0003]

During snowfall and snowfall, the road surface of the road has a low friction coefficient due to water and snow and freezes because it freezes. Therefore, it is dangerous that a person walks on a road safely or a vehicle runs. The present invention has been invented in order to respond to the strong demands of such pedestrians, traveling vehicles, and road managers.

[0004]

Means for Solving the Problems To explain the structure,
The road surface plate (1) of the present invention is fixed to a structure (3) having a recess at the lower part of the road surface. The present invention is a road surface plate used for a road having the above configuration.

[0005]

[Operation] The vehicle (4) travels on a road with a road surface plate (1), which has a large number of holes (2) penetrating the road surface and a hole size on the back side larger than that on the front surface, during snowfall. When the person (5) walks, the snow (7) above the hole is pushed into the inside of the hole due to their weight and kinetic energy, and is discharged downward from the road surface plate (1). At this time, since the size of the hole on the rear surface is larger than the hole on the front surface, the snow pushed into the road surface plate (1) is forcibly dropped without clogging or freezing. Therefore, every time the vehicle (4) and the person (5) pass, the snow (7) on the road surface plate (1) is forced into the groove of the structure (3) by the contact pressure of the tire (6) and the sole.
The snow falls naturally, and the road surface is sequentially cleared of snow.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A road (3) having a groove with a recess in the lower part of a road surface, a road having a large number of holes (2) penetrating the road surface and having a larger hole dimension on the back surface than on the front surface. Sidewalks, pedestrian crossings, driveways, and highways with fixed and laid faceplates (1).

[0007]

As described in the section of (a) Depression of the inner surface of the hole, the snow (7) on the road surface plate (1) causes the sole (4) and the person (5) to pass through the shoe sole and Snow (7) above the hole is pushed into the hole by the contact pressure of the tire.
In the normal case, since the inner surface of the hole has a larger diameter than the surface hole, the hole is discharged downward without adhering to the surface. By providing a small indentation (8) in the middle of the hole surface, even if the surface is likely to adhere to the surface, the presence of air in the small indentation (8) and the negative pressure associated with the air flow will cause
Prevents continuous adhesion to surfaces. Eventually, it falls into the groove of the structure (3) and falls naturally, and the surface of the road surface
Snow is removed. Therefore, the huge construction and maintenance costs that would otherwise be caused by providing a heating element on the road surface, sprinkling groundwater, or driving a special vehicle to remove snow can be reduced. In addition, the number of accidents caused by the sliding of the traveling vehicle (4) and the pedestrian (5) is reduced. Secondly, slippage due to brake operation during rainfall is reduced, and safety is improved. Furthermore, even during a typhoon or heavy rain flood, rainwater does not accumulate on the road surface, and even if the vehicle (4) runs at high speed, the pedestrian (5) will not be splashed or flooded and the engine will not stop, Traffic congestion will also decrease. (B) Narrow grooves on the entire surface (9) Rain water and snow-melting water on the road surface plate are guided to the holes (2), and the effect of increasing the friction coefficient of the road surface is provided to prevent accidents due to slippage.

Claims (2)

[Claims] The present invention has a large number of through-holes (2), the size of a hole on the back surface is larger than the hole on the front surface, and a small recess (8) is provided in the middle of the hole surface. 2. A thin groove (9) is provided on the entire surface of the hole (2) in a direction perpendicular to the long axis center line of the hole (2).
