(57) [Summary] [Purpose] To provide a material for vegetation for greening concrete wall surfaces. [Structure] A two-layer structure in which strips are combined in a grid and fixed at intersections and a water-permeable sheet, and one side of a horizontal strip of the strip is continuously fixed to the water-permeable sheet. The opposite side is not fixed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a material for vegetation for greening concrete wall surfaces such as retaining walls.

[0002]

[Prior art]

 In recent years, there has been a demand for greening concrete wall surfaces such as retaining walls by increasing the amount of green due to environmental issues. As one of the methods, there is a method in which the wall is made up of concrete blocks, and the surface of the concrete block is shaped so that the surface of the concrete block is filled with earth and sand, and that part is greened.

[0003]

[Problems to be solved by the device]

 However, this method is good for new concrete wall construction, but the existing concrete wall must be destroyed and then constructed, which is troublesome and very uneconomical. In order to solve the above problems, the present invention aims to provide a base material for easily greening existing concrete wall surfaces.

[0004]

[Means for Solving the Problems]

 First, the strips are combined in a grid and the intersections are fixed, and the permeable sheet is overlaid. Next, one side of the horizontal strip of the strip is continuously adhered to the water-permeable sheet.

The material thus obtained is laid on a concrete wall surface to be greened so that the surface of the strip becomes the front side and the side fixed to the water-permeable sheet of the horizontal strip is at the bottom, Fix it. Next, the soil containing the seeds and the fertilizer is filled between the horizontal strip and the water-permeable sheet.

[0006]

[Operation] When installed in this way, the horizontal strip acts just as a retaining soil, so the soil does not slip off, and the vertical strip holds the weight of the soil. Furthermore, even if the roots of the plant grow in the direction of gravity, there is sufficient soil for the width of the horizontal strip, so it will not easily die.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. First, as shown in FIG. 1, a belt made of fibers or resin, or belts 1 and 2 with fibers arranged and coated with resin around them are combined in a grid pattern to form an intersection 3 of vertical strips 1 and horizontal strips 2. It is fixed by a method such as adhesion, fusion or sewing. Subsequently, the strips 1 and 2 and the water-permeable sheet 20 such as a nonwoven fabric are laminated. Next, one side 4 of the horizontal strip 2 of this strip material is continuously fixed to the water-permeable sheet 20 by a method such as adhesion, fusion or sewing.

As shown in FIG. 2 and FIG. 3, the material thus obtained is used to make the surface of the strips 1 and 2 on the surface of the concrete wall 30 to be greened. Laying so that the side 4 that is fixed to the water permeable sheet 20 of is the bottom. Then, the vertical strip is fixed on the surface of the concrete wall 30 with concrete nails 31 and the like, and if necessary, the intersection 3 of the strips 1 and 2 is fixed to the surface of the concrete wall 30 with concrete nails 31 and the like.

Next, the space between the horizontal belt 2 and the water-permeable sheet 20 is opened from above so as to open a pocket, and seeds containing 7 kinds of mainly Western turf, organic fertilizers, water retention agents, etc. are placed therein. Fill up as much as possible with the soil 32, which is a mixture of soil and sand, up to the upper edge of the horizontal strip 2.

The width of the strip used in this example is preferably about 5 to 50 cm, and particularly in the horizontal strip, if the width is narrow, the soil cannot be sufficiently filled and it becomes difficult to green. The distance between the strips is about 30 to 200 cm for the vertical strip and about 5 to 50 cm for the horizontal strip. The material of the band material is preferably polyethylene, polypropylene, polyester, or the like, which has excellent durability, and the tensile strength of the band material is required to be at least 20 kilograms or more.

Further, as the water-permeable sheet used here, non-woven fabric, paper, woven or knitted fabric, etc. are used, and one having too good water-permeability in order to improve the water retention of the soil is not good.

[0012]

[Effect of device]

 According to this invention, the horizontal strip just acts as an earth retaining member, so that the soil does not slip off, and even if the root 11 of the plant 10 extends in the direction of gravity, the width of the horizontal strip is sufficient. Since there is a large amount of soil, the surface of the concrete wall can be greened easily and for a long time without dying easily.
