However, since these soundproof walls are made of metal, ceramic, synthetic resin, and other plate members continuously provided on the surface, the overall structure of the soundproof walls is uniform and has little change. . Also, a wall for forming a soundproof wall in which a soundproof surface of a block of ceramic or the like is used as a sound absorbing plate is known. This sound-insulating wall forming wall is convenient because it can simply be stacked to form a sound-insulating wall. However, the sound insulating walls formed by stacking the sound-insulating wall forming walls are also uniform and have little change.

[0003] If such a uniform and monotonous soundproof wall continues along the road for a long distance, the scenery of the road space is murky and scarcely changed. There is a problem that psychological effects such as are large, and the body and mind are easily fatigued. To solve this problem, vegetation may be planted in front of the soundproof wall, but the plant could not be vegetated because there is no soil on the elevated road.

As a method of solving such a problem, there is known a greening soundproof wall forming box which becomes a soundproof wall when stacked as described in Japanese Utility Model Laid-Open No. 63-104417. This greening soundproof wall forming box has a large number of small-diameter through-holes and large-diameter through-holes provided on a soundproof surface of a stackable box.
