Description

  The present invention relates to a greening structure for greening upstanding structures such as walls and fences, and a method for greening using the greening structure.

Standing structures that are relatively thin, such as walls such as revetment walls, concrete fences, and dikes in rivers and seas, stand up to partition rivers from land, etc., and concrete and block surfaces are exposed. I just did it, and it lacked the moisture and beauty of plants.
Attempts have been made to change such a murderous structure into a landscape rich in moisture and beauty by greening.
For example, like the invention described in Japanese Patent Application Laid-Open No. 2004-248533 and Japanese Patent Application Laid-Open No. 2006-8, a basket-shaped planter that accommodates vegetation soil is attached to a standing side surface, and plants are vegetated in this planter. Then, a means of greening is adopted.

The invention described in the above publication is attached to the side surface of the structure, and the load acts directly on the structure.
Standing structures include quay walls and dikes on rivers and coasts. These standing structures are required to have high strength to catch waves and water pressure, and it is preferable to constantly apply loads to the sides. Absent.
Similarly, it is not preferable to place a planter or the like on the top of the standing structure to support the weight of the structure.

In the standing structure, since it stands up like a wall, the problem is where to install the earth and sand for the plants to take root.
Even if a planter or the like is placed at a low position and greened, only the lower part of the structure becomes green, and the upper part of the high structure cannot be made green.
However, if the planter is installed at a high position, the structure that supports its weight is strong, and if it is not installed in a well-balanced manner, there is a risk of falling or falling, and a heavy load is placed on the structure. Will end up.

On the other hand, in order to make the structure greener with better scenery, it is preferable that the side surface of the structure can be greatly greened, and it is desirable that green grows not only on the side surface of the structure but also on the upper side.
However, without attaching the above-mentioned planter to the side, it is difficult to plant the side, and it is also difficult to plant trees.
