In general, soundproof walls are installed on highways, railway areas and places where houses are concentrated or noise is prevented from being transmitted to surrounding areas, especially on the roads where schools or government offices are located in the surrounding area to block or reduce external noise.

The soundproof wall is a soundproof wall for soundproofing, a soundproof wall for absorbing sound by itself, or a soundproof wall for noise interference, which is dissipated by interference between noise, .

The soundproof walls are installed on the base concrete retaining wall installed on the edge along the road with a plurality of vertical supports spaced apart from each other at a predetermined interval, and then the both ends of the soundproof panels are assembled between the vertical supports.

FIG. 2 is a perspective view showing a front surface of a conventional soundproof wall, and FIG. 3 is a perspective view showing a rear surface of a soundproof wall for a conventional road.

As shown in Figs. 1 to 3, a soundproof wall of a conventional road is provided with a soundproof panel 2 sandwiched between vertical support columns 1, and a plurality of soundproof panels 2 are stacked vertically. A sound absorbing hole 2a is formed on a front surface of the soundproof panel 2 and a space retainer 3 for supporting the soundproof panel 2 is provided at both ends of the back surface of the soundproof panel 2. [

However, since the soundproof panel of the conventional road is composed of aluminum, galvanized steel or steel and the glass fiber is simply inserted into the inside of the soundproof panel, there is a problem that it is easily corroded by a vehicle exhaust gas or calcium chloride, In addition, since the soundproof panel 2 needs to be installed or removed one by one during the replacement of the soundproof panel, there is a problem that the construction work is difficult and the maintenance and management are costly.

In addition, when the soundproof panel is made of concrete, desorption occurs, and when it is made of plastic, there is a problem that breakage or discoloration occurs.

In addition, when pressure is applied to the entire surface of the soundproof panel due to the wind pressure generated by the running vehicle or naturally occurring wind pressure, the pressure is directly transmitted to the vertical column 1, There is a problem that the installation structure becomes weak.
