DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is applied to, for example, greening by creating vegetation floors on slopes such as hills, fences such as protective fences, block walls, earth retaining walls, concrete walls, and riverbeds. The present invention relates to a vegetation floor forming method and a vegetation floor forming tool used in the method.

[0002]

2. Description of the Related Art Heretofore, as a means for forming a vegetation floor for greening such a slope or the like, there is a method of spraying a thick base material, for example. That is, a wire mesh or the like is stretched on the slope to form a groundwork for preventing collapse, and a base material of a granular material such as peat moss / bark compost is sprayed on the ground to grow the plant (vegetation). The necessary vegetation floor is created artificially.

[0003]

However, in the above-mentioned method of spraying a thick base material, a thick vegetation floor cannot be formed because the vegetation floor flows due to wind and rain. Incidentally, in the conventional construction, the thickness (depth) is about 50 mm at present, and even under optimal conditions, it is less than 150 mm at present. At such a depth of the vegetation floor, there is a problem that the plants die without sufficiently taking roots and eventually cannot achieve the purpose of greening the slope. In addition, there is an operation in which a wire net or the like must be provided on the slope in advance, which requires a construction period and a material cost.

Further, the above-mentioned conventional construction method requires heavy equipment for spraying a base material to a place where greening is to be performed. For example, in greening work along a road, it is necessary to cut off traffic and carry out construction. There was a problem.

In addition, in response to the recent trend of beautification of the environment, attempts have been made to green, for example, protective fences provided on both sides of an expressway. However, such fences are required to be provided substantially vertically. Therefore, there is a problem that even if the base material is sprayed as in the conventional construction method, it flows down due to gravity and the vegetation floor cannot be formed at all.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and is capable of greening by forming vegetation floors in all places, and without the need to stretch wire meshes or the like in places where the vegetation is formed. It is an object of the present invention to provide a method for forming a vegetation floor which can form a vegetation floor having a sufficient depth and can be easily constructed without using heavy equipment or the like, and a vegetation floor forming tool used in the method.

[0007]

Means for Solving the Problems The present invention has been made to solve such problems, and the means for solving the problems is a compressed soil 1 capable of absorbing liquid and expanding.
Is stored in a bag 2 through which liquid can flow, and then the bag 2 is laid in a place such as a slope where the bag 2 is stored in an outer package 6 through which liquid cannot flow. After the compressed soil 1 is expanded by injecting a liquid into the soil, the outer body 6 is removed and a vegetation floor is formed at a formation site such as the slope.

[0008] Further, the forming device used for the vegetation floor according to the present invention comprises a compressed soil 1 capable of absorbing and expanding a liquid, and a bag 2 capable of storing the compressed soil 1 and capable of flowing the liquid.
And an external body 6 that can store the bag body 2 that stores the compressed soil 1 and cannot flow liquid.

Further, as the compression soil 1, claim 3 also
As described in 6 , coconut fiber may be used. Furthermore, Masado 3 may be mixed into the compressed soil 1.

[0010] Further, the compressed soil 1 may be provided with the following features.
As noted, plant seeds may be provided.

[0011]

According to the present invention, the compressed soil 1 capable of absorbing and expanding the liquid is stored in the bag 2 through which the liquid can flow, and then the bag 2 cannot flow through the liquid. When the liquid is stored in the exterior 6 and the liquid is stored in the exterior 6, the liquid is stored in the exterior 6, and the liquid is stored in the exterior 6. Since the liquid sufficiently penetrates into the compressed soil 1 accommodated in 6, the compressed soil 1 absorbs water and expands. After that, by removing the external body 6, a vegetation floor having a sufficient depth for the vegetation wrapped in the bag body 2 is formed.

When the compressed soil 1 is made of coconut fiber, the coconut fiber can absorb water of about eight times or more in terms of dry weight as a characteristic of the coconut fiber. Can be used to create thick vegetation beds. Since the coconut fiber is a plant fiber and has an organic matter content of 98% or more and a PH of about 6, it is possible to supply a fertilizer necessary for plant growth without additional fertilization after construction. Furthermore, if the mashed soil 1 is mixed into the compressed soil 1, the vegetation floor to be created will be similar to natural soil.

In addition, since the compressed soil 1 is provided with seeds, after the vegetation floor is formed, the cultivation site such as a slope is naturally greened without sowing.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vegetation floor forming tool according to the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a compressed soil formed by compressing coconut fiber mixed with masato soil 3 which is a natural soil mined from a mountain or the like, and formed into a substantially plate shape. Width x thickness =
1,000 mm x 1,000 mm x 50 mm, weighing about 24 kg, with plant seeds and appropriate fertilizer embedded.

The compressed soil 1 expands about five times in volume by sufficiently supplying water. (The two-dot chain line shown in Fig. 1.) That is, when impregnated with water, the width and height are slightly expanded, but generally width x height x thickness = 1,000mm x 1,000mm x
Compressed to expand to 250mm.

The coconut fiber itself has a water content of about 20%, has an extremely high water retention capacity, can hold 8 times or more the dry weight of water, and has a very short water absorption time. Furthermore, since it is a vegetable fiber, the organic matter content is 98% or more, and the PH is about 6.

In FIG. 2, reference numeral 2 denotes a bag made of a synthetic resin net-like sheet capable of storing the compressed soil 1, and a tongue-like piece 4 is provided at one end of the bag 2 to extend therefrom. The tongue 4 is provided with three eyelets 5 at substantially equal intervals. The dimensions of the bag 2 are generally width x height x thickness = 1,000mm x
It is formed to have a size of 1,000 × 250 mm and can cover the expanded compressed soil 1 when the compressed soil 1 is hydrated and expanded.

Referring to FIG. 3, reference numeral 6 denotes a polyethylene bag-shaped outer body having an opening 6a formed at one side end thereof and capable of storing a bag 2 containing compressed soil 1 through the opening 6a. Indicates that
In the vicinity of the opening 6a, a plurality of hooks 7 having a substantially hook shape are provided at predetermined intervals. The dimensions of the outer package 6 are approximately the same as the above-mentioned bag 2, width x height x thickness = 1,000 mm x 1,000
It is formed to have a size of × 250 mm and capable of storing the expanded compressed soil 1.

A method of forming a vegetation floor on a slope protected by concrete, for example, by using the compressed soil 1, the bag body 2 and the exterior body 6 having the above-described configuration will be described below. As shown in FIGS. 4 and 5, the compressed soil 1 is stored in the bag 2, the bag 2 is stored in the outer package 6, and the hook 7 of the outer package 6 is attached to the tongue of the bag 2. By hooking near the piece 4,
The vegetation floor forming tool 8 according to the present invention is formed.

Next, as shown in FIG. 6, on the slope 9 on which a vegetation floor is to be formed, a sallow soil 3 is laid so as not to run down (this means embedding the sasa 3 on the slope 9). rear,
From above, the eyelets 5 of the tongue 4 of the vegetation floor forming tool 8 are anchored by the anchor 10. This operation is repeated, and the vegetation floor forming tool 8 is laid on the entire slope 9 as shown in FIG. The vegetation floor forming tool 8 is lightweight and plate-shaped, so it is easy to handle and can be easily constructed by human power.

Then, as shown in FIG. 8, when water, which is a liquid, is injected from the opening 6a of the outer body 6 of the vegetation floor shaping tool 8 (indicated by an arrow a), the water in the outer body 6 is formed. Is stored, and the compressed soil 1 starts to expand by absorbing water.

After the compressed soil 1 expands, that is, when it becomes approximately five times the volume, the hook 7 is removed from the bag body 2 and the outer casing 6 is removed. A vegetation bed 1 'is formed, and after a few days, seeds provided in advance on the vegetation bed 1' germinate, grow, and the slope is covered with plants.

As described above, according to the method for forming a vegetation floor according to the present invention, a vegetation floor 1 'having a thickness of 250 mm can be formed on the slope 9 so that the plants are sufficiently rooted during the growth stage and are in the process of being removed. Never wither. In addition, the vegetation floor 1 ′ does not collapse or flow due to wind and rain because the expanded compressed soil 1 is held by the bag 2 and the bag 2 is anchored by the anchor 10. .

Further, as described above, coconut fiber has an extremely high water retention capacity, so that plants do not die even on a non-water-retainable ground such as a slope compacted with concrete. Therefore, the roots of the plant are stretched around the vegetation floor 1 ', and the slope can be prevented from collapsing without wire mesh or the like.

In addition, the compressed soil 1 made of coconut fiber is like a lump of organic material and serves as a source of organic fertilizer.
For example, to supply trace elements, the vegetation floor created after construction approximates natural soil, and plants grow and die over many years without additional fertilization. An ecosystem will naturally occur.

In the above embodiment, when a vegetation floor is formed on the slope 9, the compacted soil 1 is stored in the bag 2, and the bag 2 is stored in the outer package 6, and then the outer package 6 is stored in the outer package 6. In this method, the hook 7 of the body 6 is hooked in the vicinity of the tongue 4 of the bag 2 and the eyelets 5 of the tongue 4 of the bag 2 are fixed by the anchor 10. The present invention is not limited to this. For example, a method may be used in which the bag 2 is housed in the outer package 6, the eyelets 5 of the tongue 4 are fixed by the anchor 10, and then the compressed soil 1 is housed in the bag 2. Good.

Further, in the above embodiment, when a vegetation floor was formed on the slope 9, the masama soil 3 was laid on the slope 9.
It is not always necessary to lay the mason soil 3, and the bag 2 may be directly connected to the slope 9.

Further, in the above embodiment, the vegetation floor forming tool 8 is composed of the compressed soil 1, the bag 2 and the outer casing 6, and the outer casing 6 is accommodated therein. It is provided to store the water to be injected for expanding the compressed soil 1, and the external body 6 is not an essential requirement of the present invention. When a vegetation floor is formed on a slope or the like by using the vegetation floor forming tool 8, that is, the vegetation floor forming tool 8 including the compressed soil 1 and the bag 2, the bag 2 containing the compressed soil 1 is removed from the outside. What is necessary is just to lay on a slope etc. while accommodating in the package 6.

Further, in the above embodiment, the compressed soil 1
Is made of coconut fiber, but the compressed soil 1 is not necessarily limited to this, and may be, for example, peat moss, aquatic plants and the like. However, as in the above embodiment, the coconut fiber has a high expansion coefficient, so that it can be compactly compressed, and has an advantage that it easily absorbs and restores water and has a high water retention capacity.

In the above-described embodiment, the compressed soil 1 made of coconut fiber is mixed with the mackerel soil 3. However, the compressed soil 1 does not necessarily have to be mixed with the mackerel soil 3. , Bark fertilizer or the like may be mixed, and the compressed soil 1 may be composed of only coconut fiber.

In the above embodiment, the thickness of the compressed soil 1 is 50 mm and the expanded soil is processed to 250 mm.
Needless to say, the design can be arbitrarily changed depending on the degree of the compression processing, and the horizontal width and the vertical width of the compressed soil 1 can also be arbitrarily changed. Therefore, for example, a compacted soil 1 having a size of about a chestnut stone may be used.

In the above embodiment, the bag 2 is made of a synthetic resin net-like sheet. However, the bag 2 is not necessarily limited to this, and may be, for example, linen cloth or nonwoven fabric. In other words, compressed soil 1 that water has penetrated and expanded
What is necessary is just to be able to hold so as not to flow out due to wind and rain.

Furthermore, in the above embodiment, the outer package 6 is a polyethylene bag, but the material and shape are not necessarily limited to this. The point is that any material that can be stored when water is injected can be used.

In the above embodiment, the method of forming a vegetation floor using the vegetation floor forming tool 8 on the slope fixed with concrete has been described, but the place where the vegetation floor can be formed is limited to the slope. For example, a vertical place such as a protective fence 11 on a highway as shown in FIG. 9, a dam side, a concrete block wall, a stone wall such as a house, a drainage channel 12 in which crushed stone is laid as shown in FIG. Conventionally, a vegetation floor such as a riverbed can be constructed in a place where it is difficult or impossible to construct a vegetation floor. Especially,
The vertical place such as the protective fence 11 or the drainage channel 12 where crushed stone is laid is a place where water can not be retained. However, if the vegetation floor forming tool 8 of the present invention having extremely high water retaining ability is used, there is no problem with vegetation. The floor can be constructed and greened.

[0035]

As described above, the method of forming a vegetation floor according to the present invention has the following effects by using a vegetation floor forming tool that absorbs liquid and expands to form a vegetation floor. . In other words, it is possible to carry and construct by human power.For example, even in a place where heavy equipment cannot be carried in or a place where a construction area is small, construction is possible because heavy equipment is not required, and construction cost is reduced, and There is an advantage that the construction period can be shortened.

For example, if the compressed soil is made of coconut fiber having a high water retention capacity and a high expansion rate, a thick vegetation floor can be formed after construction, so that the plants can be sufficiently rooted and grown. Become. Furthermore, even if the construction site is concrete or the like, such a vegetation floor has an extremely high water retention capacity, so that the vegetation floor does not die during growth as in the related art. Therefore, the construction site will be covered with greenery and greening will be achieved, and the roots of the plants will be spread on the vegetation floor as if a wire mesh had been stretched, thus preventing the collapse of the surface of the construction site Therefore, the cost of installing a wire mesh or the like can be reduced.

In addition, when the compacted soil is composed of coconut fiber mixed with Masato soil, it is not necessary to add fertilizer at the stage of plant growth, and the life cycle of the plant is repeated for many years, and artificial A new ecosystem will be created at a newly created site.

Further, since the compressed soil is covered by the bag, it can be applied to a vertically erected fence such as a protective fence of a highway.
Therefore, it is possible to green a place where greening work is impossible at all in the past.

Further, by providing seeds and the like in advance in the vegetation floor forming tool, the seeds will germinate and grow when the vegetation floor forming tool absorbs liquid. Will be greened.
