Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof panel having a greening plant cultivation section used for a soundproof wall installed on the side of a road such as an automobile road.

[0002]

2. Description of the Related Art Conventionally, many green plants have been used in order to improve the road landscape such as an automobile road. In addition, the soundproof wall installed on the side of the road also adopts a method of covering the surface of the soundproof wall with green plants to improve the scenery. The concrete method is as follows: (1) Provide a planting zone with natural soil in front of the soundproof wall, plant shrub or climbing type vines in the natural soil, and use shrubs or vines to Method of covering the soundproof wall, (2) A planting band filled with natural soil is provided at the rear of the soundproof wall, or a relatively large horizontal flower pot is installed, and a drooping vine plant is planted in it. We have adopted a method of covering the soundproof wall with plants.

[0003]

[Problems to be Solved by the Invention] Since a motorway passing through a city passes through a narrow urban space,
The road width is only the minimum required to secure the planned traffic volume. In addition, since the motorway that passes through the urban space is an elevated road, it is not possible to secure the land behind the soundproof wall. Therefore, when trying to improve the road landscape by covering the front or rear of the soundproof wall with green plants, it is not possible to secure a space to install a planting band in the front or rear of the soundproof wall, and therefore it is not possible to improve the roadscape. It was difficult.
