  In the greening methods of Patent Documents 1 and 2, box frames as plant growing means are attached to the entire wall surface of the wall to be planted in multiple steps, and the front surface of each box frame is greened to achieve wall greening. A large number of box frames need to be attached to the wall surface of a large area, resulting in work complexity and cost increase.

  Similarly, in the greening method of Patent Document 3, a large number of sheets or boards and nets that help climb the plant from the ground must be attached to the entire surface of a large area wall that is intended to be greened. Invite work and cost increase.

  Moreover, in the greening method of patent document 1, 2, the operation | work which sprays the muddy material used as vegetation customer soil and fills the inside of a box frame is required, and the complexity and cost increase of the said operation | work are further promoted.

  The greening methods of Patent Documents 1 and 2 are based on the idea of greening the front face of the box frame and greening the wall surface of a large area, and Patent Document 3 is a greening method that helps the vines climbing from the ground. Both of them are difficult to implement properly as a method of planting vines and the like from the upper side to the lower side of the wall surface, and in particular, in the greening methods of Patent Documents 1 and 2, the land of land is damaged by rainwater. There is a problem of erosion and runoff.For example, when revetment walls of rivers, etc., the above-mentioned box frame, etc. will sink under the surface of the water and the vegetation soil will be washed away. It is.

In the present invention, a plurality of plant growing box baskets accommodating and holding a plant growing mat are arranged in a line along the top edge of the planted wall, for example, and the wall greening net is formed along the surface of the planted wall from the lower end of the plant growing box basket. Is a wall surface greening structure in which a vine plant grown from the plant growth mat through the plant growth box basket is entangled with the wall greening net to green the wall of the planted wall directly under the plant growth box basket.
The plant growing box is attached with the back side attached to the side of the planting wall, a water receiving box is provided on the bottom surface of the plant growing box, and the wall greening network extends along the surface of the planted wall from the lower back of the plant growing box. Suspend.
As the hanging means, the upper side of the wall greening net is hung on the lower back side of the plant growing box fence through a hanging tool, or the upper side of the wall greening net is attached to the back side of the water receiving bowl with a screw. A net is hung from the lower back end of the box.

  According to the present invention, a limited number of plant-growing box culverts are juxtaposed along the upper side of the wall surface that needs to be greened, and the plant is grown by a simple method of hanging the wall-surface greening net so as to cover the wall surface. By cooperating with the box wall and the wall greening net, it is possible to easily and beautifully plant a large area of the wall and maintain it effectively.

  Especially when the method of hanging down the vines planted on the ground behind the top of the revetment wall of rivers, etc. is used, the hanging vines will rise up or be washed away by the water flow. Although there is a problem, the present invention is effectively solved by the wall greening net, and the plant growing box is not affected by the increase of river water.

  In addition, rainwater or water supplied from the irrigation device penetrates into the plant growth mat in the plant growth box basket to give moisture to the vines, while surplus water is received in the water receiving tank provided on the bottom of the plant growth box basket. And assists the water retention effect of the mat.
