Description

Detailed Description of the Invention

[0001]

[Industrial application] The present invention makes it possible to combine the conventional frame construction method and vegetation construction method for the purpose of preventing collapse of cut slopes and vegetation greening, and also helps to create and restore an ecological environment. The present invention relates to a vegetation method that has a functioning slope and preserves the ecosystem.

[0002]

2. Description of the Related Art Conventionally, various vegetation methods have been developed and applied in various fields to prevent collapse of cut slopes and slopes and to grow plants. The vegetation method is roughly classified into a spraying method, a glue frame method, a vegetation board laying method, and the like.

In the above-mentioned spraying method, as shown in FIG. 1, a spraying material such as wood fiber is made into a slurry by adding a large amount of water, and is made into a slurry, which is provided with a high performance pump (hydroseeder). ), The seed spraying method that sprays without unevenness of the slope, or the spraying material such as black soil (cohesive soil), seeds, chemical fertilizers, erosion inhibitors, and water is made into a slurry, and hydrocedar is used. The method of spraying the soil with a predetermined thickness onto the surface, or mixing the spray material such as seeds, chemical fertilizer, erosion inhibitor, and water with the organic growth base material in the mortar spray machine, There is a thick layer base material spraying method in which air is sprayed on the slope to a thickness of 3 to 10 cm at a time.

The glue frame construction method includes an on-site frame construction method for constructing and forming a grid-like frame on the site of a cut slope or a natural slope,
There is a precast frame construction method in which factory products are assembled while assembled in a grid pattern on site. In any case, vegetation sandbags or vegetation base materials, or a combination of these and cobblestone are packed in the finished glue frame. Moreover, the glue frame construction method includes a restraint work that simplifies the prevention and protection of slope slopes and a restraint work that prevents collapse in earnest.

Further, the vegetation board laying construction method is a method of constructing the vegetation board so that the vegetation board is fixed to the slope with anchor pins or the like, and the slope is greened.

[0006]

[Problems to be Solved by the Invention] Whether to use the vegetation board laying method, the spraying method, or the glue frame method depends on the geology of the slope, topography, slope, spring water, surface erosion, unevenness. Depending on the conditions such as above, the former two are mainly aimed at the greening of the slope, and little consideration is given to the prevention and protection functions of the slope. On the other hand, in the latter, the main purpose is to prevent or protect the slope from collapsing and the greening of the slope is a secondary purpose. In other words, even if the plant grows, only the inside of the frame will be green, and the artificial grid-shaped glue frame will always be exposed on the slope, and the landscape after completion of greening will be compared to the entire greening of the slope. Then, it will be lowered. The present inventor has a vegetation method capable of simultaneously satisfying the two problems that the slope can be prevented from collapsing and the glue frame method that has a protective effect can be applied to fully green the slope and improve the landscape. Was researching.

The conventional vegetation method is developed only in consideration of germination, survival and growth of plants, and the vegetation as a material therefor is seeds, fertilizers, water retention, soil improvement, etc. However, no consideration was given to the ecosystem including the biological chain between plants and small animals and the small animal chains around the plants.

[0008] For this reason, even if some slopes are replanted by the revegetation work, the temporarily rooted plants do not adapt to the local climate and climate, or to the surrounding ecosystem. And sometimes it did not grow permanently. In such a case, the greening work must be redone every few years. In addition, even if it seems that nature has returned to the appearance that grass has temporarily grown due to greening work, ecosystems such as microbes, earthworms, beetles, other insects, aquatic animals and other small animals, birds, fish, etc. Since it has been destroyed, it has a great impact on the surrounding environment, and the small animals that used to live in the surrounding areas disappear, birds do not come in, and the plants that used to grow die. It may result in expanding the area of environmental destruction.

While the inventor has been working for many years as a greening-related business, the greening work by vegetation that he has carried out is carried out under the name of natural environment conservation and restoration. However, it has become clear that this is nothing more than an artificial greening, and that it is not yet a natural restoration.

Based on such experience and reflection, the present inventor feels that it is necessary to evolve into a vegetation method for conservation / restoration or creation of an environment with an emphasis on natural ecosystems, and research therefor. The present invention has been developed through repeated improvements. Such an idea of the inventor is that even if it is impossible to restore a complete natural ecosystem, "a homogeneous and limited area with specific environmental conditions that allows specific biological communities to exist" (biology It is based on the concept of biotope (BIOTOPE <English / French>), which is defined as creating a dictionary.

That is, according to the present invention, the slope frame construction method is used to sufficiently prevent and protect slopes from collapsing and protect the ecosystem of a porous environmental structure constructed on the basis of the concept of biotope on the grid frame of the grid. After installing a bag for vegetation, vegetation method by spraying method is applied to achieve greening of the entire surface, but at the same time, realize a new vegetation method that helps to create a predetermined ecological environment area on the slope. The purpose is.

[0012]

[Means for Solving the Problems] While conducting various studies on the conditions and means for embodying the ecological environment area based on the concept of the biotope described above, one of the environmental conditions in which fauna and flora are easy to survive is various holes and I realized that the existence of the gap is important. For plants, for example, it is important that there is sufficient space in the rooting soil, for animals,
The existence of various holes and gaps that hide the body and run the nest is essential. In other words, a porous environment with as many gaps as possible is essential for the restoration and creation of rich ecosystems.

However, the conventional vegetation method is limited only to the protection of slopes and the growth action of plants, and the action of ecological linkage between plants and animals cannot be considered. I had no idea. The present invention provides a vegetation method suitable for constructing one ecological environment area based on the concept of biotope. Therefore, a part of the vegetation method is intentionally provided with a physical structure called a porous environment structure. And That is, the present invention is a vegetation method that simultaneously possesses a slope collapse prevention and protection function, a slope surface greening function, and a function capable of inhabiting a specific biological community.

The first invention for which a patent is sought is constructed so as to provide a grid-like frame made of concrete or mortar on the slope, and a vegetation sandbag or a vegetation base material or these and a slag stone Installed so that the ecological conservation bag with a porous environmental structure is fixed along the upper surface of the grid-shaped glue frame, and then the ecological conservation bag is almost buried. This is a vegetation method for ecological conservation on the slope, which is characterized by spraying the soil.

A second invention to be granted a patent is to construct a grid-like frame made of concrete or mortar on the slope, and to install a vegetation sandbag or a vegetation base material or these and a slag stone in the sill frame. In addition to packing the combination of the above, a core material made of rope, hemp rope, or any other filament formed of plant fibers, and at least a shape-retaining granular material, a water retaining material, and a soil improving material are mixed. The ecological preservation bag, which is made by packing a porous structural material consisting of a net body, a non-woven fabric or a cloth, which is difficult to corrode, into a bag body for ecological protection, on the upper surface of the grid frame. This is a slope-type ecological conservation type vegetation method characterized by being installed along with it, and then spraying the soil for vegetation to the extent that the ecological conservation bag is almost embedded.
