DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for greening a slope formed when a forest, a plateau, or the like is opened to construct a road, a residential land, or the like.

[0002]

2. Description of the Related Art A slope formed when a mountain forest, a plateau, or the like is cut open is designed to prevent landslides and the like by vegetating and greening the surface. The slope that has been greened by vegetation is covered by plants, and is in a state that does not feel uncomfortable with the surrounding environment.

When greening a slope, for example, Japanese Patent Application Laid-Open
As disclosed in Japanese Patent Application Laid-Open No. 3-284322, a slope is covered with a wire mesh, and a vegetation base material mixed with soil, fertilizer, seeds, and the like is sprayed by a pump.
However, when the vegetation base material is directly sprayed on the slope in this way, the sprayed vegetation base material may flow down the slope.

[0004]

In order to solve such a problem, a slope frame is usually formed on the slope by concrete or the like, and a mixture of soil, fertilizer, seeds, etc. is formed in the slope frame. A method of spraying a vegetation base material consisting of However, in such a method, the vegetation base material sprayed into the inside of the concrete slope frame does not flow down, but the sprayed vegetation base material is attached to the surface of the concrete slope frame. No vegetation can be planted on the surface of the slope frame. As a result, the surface of the slope frame made of concrete or the like is exposed in a grid pattern on the slope, which impairs the appearance.

Japanese Patent Application Laid-Open No. 58-213921 discloses a method in which a cardboard box containing soil, fertilizer, seeds and the like is placed in a concrete frame and vegetated. However, even with such a method, the vegetation cannot be vegetated on the surface of the concrete frame, and the surface of the concrete frame is exposed on the slope to impair the aesthetic appearance.

A slope frame formed of concrete or the like has recently been constructed by arranging wire ropes, reinforcing bars, and the like in a grid pattern on the slope face, fixing them with anchor bolts or the like, and arranging the wires in a grid pattern. It is formed without using a mold by spraying mortar along a rope, a reinforcing bar or the like. However, fixing a relatively heavy wire rope or a reinforcing bar to a slope requires a large number of anchor bolts and the like, and there is a problem that the fixing operation is not easy.

[0007] The present invention is to solve such a problem, and an object of the present invention is to provide a method of greening a slope capable of vegetation over the entire slope. It is another object of the present invention to provide a method for greening a slope, which is extremely easy to perform.

[0008]

According to the present invention, there is provided a method for revegetating a slope, comprising the steps of: providing a slope frame having synthetic wood or natural wood, and a chip-like anchor material attached to the surface of the wood;
Seeds are mixed with soil over the entire surface of the slope frame and the slope surface where the slope frame is not placed, with the process of fixing along the slope in an almost horizontal state with an appropriate gap in the vertical direction Laminating the vegetation base material thus obtained.

The slope frame used in the greening method of the present invention is:
Any cross-sectional shape may be used as long as it is synthetic wood or natural wood to which a vegetation base material mixed with seeds, soil and the like can adhere to the surface. Synthetic wood or natural wood may be used alone as the slope frame.However, in a slope frame in which a chip-shaped anchor material is bonded to the surface of synthetic wood or natural wood with an adhesive, the vegetation base material is used. This is preferable because it is securely held on the surface of the slope frame. In addition, by adhering a fertilizer component that promotes plant growth to the surface of synthetic wood or natural wood, plant growth on the slope frame surface is promoted.

As the synthetic wood, a glass fiber reinforced foamed polyurethane resin molded product, for example, trade name "FFU" (manufactured by Sekisui Chemical Co., Ltd.) is preferable.

As the chip-shaped anchor material bonded to the surface of synthetic wood or natural wood with an adhesive, coarsely crushed synthetic wood, milling waste or the like which is not likely to rot is suitably used. Moreover, you may mix and use the crushed material of synthetic wood and the crushed material of natural wood appropriately. Such a chip-shaped anchor material is such that one side is adhered to synthetic wood or natural wood by an adhesive, and the other side protrudes from the adhesive so that a vegetation base material having soil, seeds and the like can be held. However, any chip having a certain length or more may be used. The anchor material may be used as a single layer as long as it has a length of 10 mm or more, and in the case of an anchor material as short as about 2 mm, it may be used by laminating a plurality of layers.

Since the anchor material using synthetic wood has a relatively high strength, even if the surface of the synthetic wood or natural wood is steeply inclined, the vegetation base material laminated on the anchor material is used. Can be stably held without falling.

The adhesive used for bonding the anchor material to the wood has a strength necessary for bonding the anchor material to the surface of synthetic wood or natural wood, and is water-resistant. Those that have no adverse effect on plants are used.

[0014] The anchor material can be applied to the synthetic or natural wood surface by sprinkling the applied or sprayed adhesive or by the flocking method in a state of being substantially uniformly dispersed in the adhesive. Is adhered so as to be partially protruded from the adhesive. Also, by spraying the adhesive and the anchor material simultaneously on synthetic wood or natural wood by a spray-up method, which is one of the molding methods of the fiber reinforced resin, a state in which a part of the anchor material protrudes from the adhesive. Can be glued to synthetic or natural wood. In the spray-up method, the anchor material may be along the surface of synthetic wood or natural wood and may not sufficiently project from the adhesive layer, but in this case, the shape of the anchor material is irregular and easily entangled What is necessary is just to use a thing or a flocking method together.

When the anchor material adheres to the adhesive on the synthetic or natural wood and the adhesive is semi-cured or after it has hardened, again on the anchor material bonded to the synthetic or natural wood, If a new anchor material is adhered by the flocking method, the anchor effect on the vegetation base material laminated on the anchor material is significantly improved.

As the vegetation base material, a mixture of seeds mixed with soil, fertilizer, etc. suitable for growing plants is usually used, and such a mixture is sprayed by spraying over the entire slope surface and slope frame surface. Can be

[0017]

According to the planting substrate of the present invention, the vegetation base material is adhered to and held on the surface of the slope frame having synthetic wood or natural wood. Does not become exposed. Since it is made of synthetic wood or natural wood, it is lightweight and can be easily fixed to a slope.

In a slope frame in which a chip-shaped anchor material is adhered to the surface of synthetic wood or natural wood by an adhesive,
The vegetation base material is stably held on the slope frame surface.

[0019]

When through holes are provided in synthetic wood or natural wood, seeds that have germinated in the vegetation base material are rooted on the slope through the through holes.

[0021]
