To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

In addition, in the following description of the present invention, if it is determined that related related technologies and the like may obscure the gist of the present invention, detailed description thereof will be omitted.

1 is a view showing a schematic view of the fog reduction structure of roads and bridges using a water roof method according to an embodiment of the present invention.

FIG. 1 clearly shows only the characteristic parts in order to conceptually clearly understand the configuration relationship for the preferred embodiment of the present invention. As a result, various modifications of the drawings are expected and need to be largely limited to the specific forms shown. There is no.

Referring to FIG. 1, the mist reducing structure of roads and bridges using a water roof method according to an exemplary embodiment of the present invention includes tunnel-shaped water along a trace of a parabolic shape that crosses an upper portion of a road and a bridge. By obtaining a water roof spraying movable unit 110 forming a roof and a fog image on the passage section, the visibility is calculated, as well as the fog velocity and the wind direction are detected to detect the fog concentration and It consists of a configuration including a fog observation unit 120 for calculating the inflow direction, and a control unit 130 for controlling the injection strength of the water roof flow rate discharged by the water roof injection movable portion.

As shown, when the fog flows into the passage section on the road (R) where the fog occurs habitually, it interferes the watch of the vehicle driver to act as a cause of various vehicle accidents. The fog generated from the terrain includes the fog generated in the neighboring area and introduced into the side of the road R, and an identity fog such as radiant radish formed on the upper layer of the road R.

Conventionally, to prevent the inflow of the fog by installing a physical barrier to block the inflow of the fog on the outer sides of the road (R), this method to temporarily block the fog flowing from the side Is limited, it is difficult to effectively block the influx of identity fog formed on the upper road (R).

For this reason, in order to effectively block the fog flowing into the side of the road and the bridge, as well as the fog spreading from the upper layer of the road and the bridge, the present invention provides a water roof that can block the passage section into an enclosed space.
