Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning structure for a soundproof panel installed along a road or railway, and a soundproof wall provided with this cleaning structure.

[0002]

2. Description of the Related Art In order to block noise from vehicles, sound barriers are installed along roads and railways. Some soundproof panels used for such soundproof walls are formed of an opaque face plate, but a soundproof panel formed of an opaque face plate has a feeling of oppression because the surrounding scenery is blocked by the opacity, In addition, since it lacks in landscape, recently, soundproof panels formed by a face plate having transparency are widely used so that the surrounding landscape is not obstructed.

[0003]

However, since such a soundproof panel is installed and constantly exposed to the exhaust gas and dust of the vehicle, it is contaminated by the exhaust gas and dust, and there is a problem that the landscape is impaired. Particularly, in a soundproof panel having a see-through property, contamination is conspicuous, and the contamination may impair the see-through property.

However, since the soundproof panel is sometimes exposed to rainfall, it is expected to be washed with rainwater. However, this is also only the area exposed to rainfall. For example, when a soundproof panel is installed under an elevated road or curved above the road, the outside of the soundproof panel on the private side is The surface of the sound-proof panel is easily exposed to rain and can be expected to be washed with rainwater, but the inner surface of the soundproof panel, which is the road side, is less likely to be exposed to rain and is more polluted than the outer surface. Cleaning with rainwater cannot be expected. That is, in the above example, the inside surface of the soundproof panel cannot trace the attached pollutant effectively because only a small amount of rainwater is transmitted to the inside surface by natural rainfall. If pollutants adhere to and accumulate, it cannot be effectively cleaned even if a large amount of water is supplied.Therefore, the inside surface of the soundproof panel should be sprayed with water directly from the work vehicle before pollutants accumulate. Or, it is necessary to regularly clean with a sprinkler.

If a photocatalyst-containing layer is formed on the surface of a soundproof panel and the photocatalyst-containing layer is irradiated with ultraviolet rays, the photocatalyst is activated and the surface thereof is hydrophilized, so that contaminants are less likely to adhere, and It is known that adhered pollutants are easily washed by rainwater when exposed to rainfall.
However, on the inner surface of the soundproof panel which is not easily exposed to rainfall as in the above example, cleaning by the photocatalyst containing layer cannot be expected only by natural rainfall. Therefore, even if the photocatalyst-containing layer is formed, the inner surface of the soundproof panel still needs to be sprayed with water directly by a work vehicle or periodically washed with a sprinkler or the like.

Therefore, the present invention solves the above problems,
A soundproof panel cleaning structure for effectively cleaning a soundproof panel by rainwater, and a soundproof wall provided with this cleaning structure.

In the embodiment shown in FIG. 19, a soundproof device (hereinafter referred to as soundproof device 8 etc.) for absorbing 1 to reduce the headstock and diffracted noise is provided above the gutter-shaped rain receiving portion 7 as described above. The rainwater W, which has fallen on the soundproofing device 8 and the like, is transmitted through the soundproofing device 8 and flows into the rain receiving portion 7.

In the embodiment shown in FIG. 20, the soundproof panel 1 has an upper portion,
The soundproofing device 8 is provided, and the inner side surface 82 and the outer side surface 83 of the mounting base 81 of the soundproofing device 8 are flush with the inner surface 12 and the outer surface 11 of the upper part of the soundproof panel 1, respectively. , Or the rainwater W, which comes into contact with the soundproofing device 8 in a slanting manner smoothly, travels along the inner and outer surfaces 82 and 83 of the mounting base 81 of the soundproofing device 8 and the soundproofing panel 1
It is designed to be guided on the inner and outer surfaces 11 and 12.

The soundproof panel 1 of FIGS. 1 to 20 described above
Is designed to be washed only by natural rainfall, but a photocatalyst containing layer is further formed on the inner surface 12 and / or the outer surface 11 of the soundproof panel 1, and the photocatalyst containing layer is exposed to ultraviolet rays. If the photocatalyst is activated by irradiation and the surface thereof is made hydrophilic, contaminants are less likely to adhere, and the adhered contaminants are effectively washed with rainwater W.

The type of photocatalyst is not particularly limited, but titanium dioxide is generally preferably used.
Titanium dioxide may be rutile type, but is preferably anatase type due to its high activity. Titanium dioxide is activated by irradiating it with ultraviolet rays having a wavelength range of about 300 to 400 nm, and is strongly oxidized by the activation. When force is exerted, the contaminants adhering to the surface are decomposed, and the surface is contacted with water at a contact angle of almost 0 due to activation.
It becomes hydrophilic up to about 20 degrees, and the hydrophilicity makes it difficult for contaminants to adhere, and even if it adheres, it is easily washed away by rainfall or the like.

As described above, according to the present invention, the soundproof panel 1 is washed by natural rainfall. When the soundproof panel 1 is installed and has a surface exposed to rain and a surface difficult to be exposed to rain, for example, installed under an elevated road. It is extremely effective when installed on the road or curved above the road, and is directly below the upper frame member 3 of the soundproof panel 1 in which the frame members 3 and 4 are attached to the face plate 2 and the upper part of the soundproof panel 1. When the headstock 6 and the soundproofing device 8 are attached to the above, it is also effective to wash a portion such as directly below the headstock 6 and the soundproofing device 8 which is hard to be exposed to rainfall.

However, the present invention is not limited to these installation places and configurations, and even if the soundproof panel 1 is installed in a state where the inner surface 12 and the outer surface 11 are always exposed to rainfall, it is not possible to use the conventional structure. Cleaning is expected to be extremely effective in comparison. In the present description, the outer surface 11 of the soundproof panel 1 is described as the civil side and the inner surface 12 is described as the road side. However, depending on the location and form of the installation, for example, the curved surface is installed on the civil side. For example, the surface that is difficult to be exposed to rainfall may be on the private side, and in the case of being installed in the central separator of the road, both the inner surface 12 and the outer surface 11 are on the road side. Therefore, the outer surface 11 and the inner surface 12
The surface does not necessarily mean the surface on the road side or the surface on the private land, but means one surface and the other surface of the soundproof panel 1. Normally, the surface easily exposed to rainfall is the outer surface. If both surfaces are easily exposed to rainfall, either surface is the outer surface 11.

The water guiding hole 5 is preferably formed over the entire area of the soundproof panel 1 in the longitudinal direction, but if it cannot be formed over the entire area due to the structure, it may be partially formed. Alternatively, a packing having water permeability to an extent that does not hinder the flow of the rainwater W may be inserted to prevent the face plate 2 from vibrating.
