する方法が一般的であった。2. Description of the Related Art Conventionally, as a method of planting vegetation on a slope, a method of attaching a bag filled with a vegetation base material to a main mesh stretched on the slope or a fine mesh on the main mesh is known. In general, a method of attaching a bag formed by the method described above and filling the vegetation base material into the bag is common.

盤材を充填することができなかった。In the method of attaching a bag on the slope and filling the vegetation base material therewith, the slope having irregularities is filled with the vegetation base material by positioning the bag along the recess. However, on a slope with few irregularities, if the net stretched on the slope is not lifted, a space as a pocket is not formed in the bag, and therefore, the vegetation base material cannot be filled.

退してしまった。Furthermore, in any of the above methods, the fallen leaves hardly accumulate on the vegetation base after the construction, and the fallen leaves can hardly be retained particularly on a steep and smooth slope. The plants grew as long as the vegetation base material had nutrients, but gradually declined when nutrients were lost.

図ることとした。Therefore, a first means of the present invention is to attach a rod-shaped core material to the upper end of the net and to separate the core from the main net stretched on the slope. The lower end of the mesh body in a state where the pocket is formed with the mesh body kept loose in the vertical direction while the opening is formed between the core material and the main mesh body by attaching and fixing. The vegetation was fixed by fixing it to the net and filling the vegetation base material inside the pockets.

With an opening formed between them, the mesh is fixed to the main mesh in a state where the mesh is held loose in the vertical direction and the pocket is formed, and it is stretched on the slope to create a pocket. Vegetation was planned by filling the vegetation base material into the inside of the section.

で、植生基盤材を保持し、且つ落ち葉を堆積させること
ができる。According to the present invention, a pocket is formed by attaching a core material at an interval above the main net so as to form an opening, thereby forming a pocket even on a slope with little unevenness. Since the shape of the pocket having an opening can be maintained, the vegetation base material can be held and fallen leaves can be deposited.

There is a reinforcing effect. Moreover, if the material of the barbed portion of the barbed wire is decomposed or corroded over time, the young tree,
Prevention of feeding damage only at the seedling stage, and it is possible to coexist with animals after plant growth.

たポケット体６が取り付けられている。FIGS. 1 and 2 show steps in an embodiment of the present invention. First, as shown in FIG. 1, a main net 2 having a large mesh is stretched on a slope 1. A rod-shaped core material 5 is attached to the upper end of the net 3, and a pocket 6 having a pocket 4 formed below the main net 2 is attached to the main net 2.

することによって取り付けられる。As shown in FIG. 1, for example, the pockets 6 are formed by connecting the hooks at both ends of a hook 21 with hooks to the main mesh 2.
By hooking the core member 5 on the core member 5, the core member 5 is suspended from the main mesh body 2 and fixed at appropriate intervals to form an opening 10 upward, and the lower part of the mesh body 3 is loosened in the vertical direction. The main net 2 is fixed by an anchor 9 or the like while being held.

が可能となる。As the main net 2, a net made of a resin such as geotextile or a wire net such as a rhombic wire net is used in many cases. The net 3 is made of the same material as the main net 2,
In order to form the pocket portion 4, it is necessary that the pocket portion 4 be easily bent, and one having a small mesh is preferable. As the core material 5, a vinyl chloride tube, a small-diameter steel tube, or the like is used. For example, the core member 5 is inserted into a bag formed by bending and sewing the upper end of the net 3. This core material 5 may be inserted in the net 3 in advance, but if it is inserted after the net 3 is installed at the site, an arbitrary material and size can be selected according to the situation at the site. It becomes possible.

い。Then, an L-shaped holding member 22 is fixed below the pocket body 6 on the slope 1 with a fastener 29 such as a concrete nail or an anchor pin as shown in FIG. 2 is prevented from shifting, and the pocket body 6 is prevented from sliding down along the slope of the slope 1. The holding member 22 may be a strip, a steel pipe, or another shape as long as it can prevent slippage of the slope 1 such as concrete. Preferably, it is a long material extending in the lateral direction. Aluminum or stainless steel, which is resistant to corrosion, is used when durability is particularly required. However, when the roots enter the inside of the slope 1 and are firmly fixed, the roots are fixed. For example, a bamboo material, wood, or the like that corrodes later may be used.

のではない。The inside of the pocket portion 4 is provided with a sheet 7 having an earth retaining effect and a heat insulating effect, so that the vegetation base material 31 can be held and drying and freezing can be prevented. For example, a Russell net is used as a sheet having an earth retaining effect, and a foamed polyethylene sheet having a thickness of about 3 mm to 5 mm is often used as a sheet having an insulating effect. It does not do.

どを柔軟に選択できるという利点がある。Such a pocket body 6 including the sheet 7 and previously attached to the main net 2 may be stretched on the slope 1, or first, only the main net 2 may be attached to the slope 1. After being stretched above, each may be attached and formed on site. In the case of the former, there is an advantage that the quality of the pocket body 6 is stable and the number of steps at the site is reduced. In the case of the latter, since individual materials are not bulky and light, heavy machinery and the like are required during transportation and construction. In addition to the necessity, there is an advantage that a material, a dimension, an installation position, and the like can be flexibly selected according to a site situation such as a change in the shape or gradient of the slope 1.

Holds the position of the core material 5 by tension, so that it also keeps the shape of the pocket portion 4 and protects the vegetation base material 31. If the barbed wire 8 is made of a material that corrodes, for example, like iron, or a resin that decomposes with the passage of time, the barbed wire 8 will not be damaged by the plant in the pocket portion 4 only during the seedling stage. After the plant has grown, the spines 8a disappear and the invasion of animals becomes possible,
It can be made to live with animals. However, if it is desired to prevent the invasion of animals even after the growth of the plant, the barbed wire 8 including the spines 8a may be formed of a durable material such as stainless steel.

こともある。As the vegetation base material 31, a mixture of bark compost and peat moss is used. However, it is necessary to make the inside of the pocket portion 4 as light as possible so that a large amount of fallen leaves can be deposited. Not only that, but it is also preferable for preventing water retention and vegetation base material 31 from drying. If early greening is desired, seedlings may be planted.
【００２４】また、ポケット体６は、法面１上に千鳥状

養分を補うので、植物の衰退を防ぐことができる。According to the present invention, even on a smooth slope such as concrete, the shape of the pocket portion opened upward is maintained by the core material attached at a distance from the slope, so that the vegetation base can be maintained. The material is easy to fill, and the fallen leaves are apt to accumulate, gradually becoming mulch and naturally supplementing nutrients, so that the decline of plants can be prevented.
【００２６】また、植生基盤材の重さに対しても、ポケ

きる。If the core material is connected with barbed wires from the shoulder to the butt, the invasion of animals can be prevented and the damage to food can be prevented. Moreover, if the barbed wire is made of a material that corrodes or decomposes, depending on the material of the barbed wire, it can prevent eating damage only at the seedling stage and can coexist with animals after the plant has grown, and can be durable. In the case of using a material having, the invasion of animals can be permanently prevented. Further, it can also serve as a reinforcing material for holding the position of the core material.
