The present invention relates to a soundproofing wall for a road. The soundproofing wall is installed in a relatively higher position than a road surface by being installed on a foundation concrete, in general. But, a wind pressure generated when a vehicle drives slantly ascends by generating a vortex from the lower side to the upper side, and ventilation performance of an existing soundproofing wall for a road, which has a high rotation force and a smooth ventilation structure when being applied with the wind pressure in a horizontal direction, highly deteriorates against the wind pressure flowing in an inclination direction. So, the existing soundproofing wall for a road is unsuitable for the wind pressure flowing in the inclination direction. According to the present invention, the soundproofing wall for a road absorbs noise generated on a road side in the soundproofing wall and reduces a wind load by enabling the wind pressure to flow into a path formed to be inclined to a forward and lower side and a rear and upper side and discharging the wind pressure. The soundproofing wall for a road intermittently absorbs and blocks the noise flowing into the path by using the rotation force. So, the soundproofing wall for a road can prevent the noise from flowing into a residential district. |
