DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a vegetation floor and a vegetation floor forming tool applied to greening a construction surface such as a slope, and more particularly to concrete, block, and the like.
Exterior surfaces of slopes constructed with masonry or natural stone walls, civil engineering structures such as seawalls, buildings such as buildings constructed of concrete, etc. (hereinafter referred to as "construction surfaces such as concrete slopes")
The present invention relates to a method for forming a vegetation floor and a vegetation floor forming tool applied for greening the vegetation floor.

[0002]

2. Description of the Related Art Conventionally, greening of civil engineering structures such as slopes and outer surfaces of buildings such as buildings has been actively performed, and there are various methods. For example, by spraying a pulverized base material such as peat moss and bark compost on the construction surface to artificially create a vegetation floor necessary for vegetation (plant growth) or construct a bag containing the base material A method of laying on a surface for greening is known.

[0003]

However, when the construction surface is constructed of concrete or the like, it is difficult to vegetate by the conventional method because the construction surface is impervious to water.

That is, when a vegetation floor is formed on a ground with exposed soil by a conventional method, the vegetation floor is raised by the land's capillarity, which raises the water holding power of the land and raises the retained water even if it does not rain for a long time. Although the problem of depletion is small because water is supplied to the surface, but in order to green the construction surface such as concrete slopes, which are non-water-retaining construction surfaces, for example, the granular material consisting of peat moss and bark compost on the construction surface Spray the base material of
If the vegetation floor necessary for vegetation is artificially created, only the vegetation floor has water retention, so if there is no rainfall for a long time, the vegetation floor will be depleted immediately and vegetation will not be sufficient. There was a problem.

[0005] As means for solving this problem, a method of separately providing a water pipe or the like on a vegetation floor to provide a watering facility, removing concrete on a construction surface to expose the ground, and removing the vegetation floor from above. Although there is a method of constructing the structure, the former method has a problem that the construction cost is increased, and the latter method not only requires a large amount of work but also causes a problem of disposal of concrete fragments as industrial waste, which is not preferable. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and a concrete slope which can easily and surely be greened without separately providing watering equipment or removing concrete or the like. It is an object of the present invention to provide a vegetation floor creation method and a vegetation floor creation tool on a construction surface such as.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and the means for solving the problem is as follows. A vegetation floor composed of an adhering body 1, a water-absorbable hydrophilic body 2 provided on one side 1 a of the adhering body 1, and a base material 3 provided on one side of the hydrophilic body 2. And a part of the hydrophilic body 2 is brought into contact with a water source 12 on a construction surface 10 such as a concrete slope, as in the method for creating a vegetation floor according to claim 1. The vegetation floor is formed by laying along the construction surface 10 in a state where the vegetation floor is laid.

According to such a vegetation floor forming tool, the roots of the plants that have grown by absorbing nutrients and the like from the base material 3 are not affected by the water from the hydrophilic body 2 provided between the base material 3 and the rooting body 1. By receiving the supply and continuing to grow, it will take root and become rooted in the root body 1. Then, using such a vegetation floor forming tool, a hydrophilic body
2 is laid along the construction surface 10 with the part of the construction 2 being in contact with the water source of the construction surface 10 such as a concrete slope, so that water can be transferred from a part of the hydrophilic body 2 to the hydrophilic body 2. Is absorbed, and the water is supplied to the base material 3 by spreading the water to the hydrophilic body 2. Therefore, even in a place where water cannot be retained, such as a construction surface 10 such as a concrete slope, water is supplied via the hydrophilic body 2, so that plants do not run out even if it does not rain for a long time.

In the meantime, the construction method such as a concrete slope is used without using the vegetation floor forming tool 7 as in the construction method of the second aspect.
10 lay a root body 1 through which plant roots can enter, and place a hydrophilic body 2 capable of absorbing water on the root body 1,
The water of the water source 12 is supplied from the hydrophilic body 2 to the base material 3 even if the base material 3 is laid on the hydrophilic body 2 by laying it in contact with the water source 12 So the plant never runs out. However, in the case of the creation method using the vegetation floor formation tool 7, the vegetation floor is formed by simply laying the vegetation floor creation tool 7 on the construction surface 10 such as a concrete slope, so that the workability is good. There is an advantage.

Further, as described in claim 3 or 6, the root body 1 and the hydrophilic body 2 of the vegetation floor forming tool are formed in a bendable sheet form, and the base material 3 is accommodated in the bag body 5 in a state of being stored in the bag body 5. If it is provided in 2, the vegetation floor forming device can be rolled or folded, so that storage and transportation can be simplified.

Further, if the hydrophilic body 2 is made of a material having a capillary action, the water absorbed from a part of the hydrophilic body 2 diffuses quickly, It will be conveyed to the whole hydrophilic body 2. Therefore,
For example, even when the construction surface 10 has a large area and only one water source 12 is provided, the water is distributed over substantially the entire hydrophilic body 2.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a vegetation floor forming tool according to the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a sheet-like rooting body to which plant roots can adhere, and is made of, for example, a nonwoven fabric of hemp fiber. In addition, the non-woven fabric, felt, or woven fabric of natural fibers such as cotton, cow hair, and jute may be used for the root body 1.

Also, viscose rayon acetate.
Non-woven fabric of artificial fiber such as acrylic, metal fiber such as steel wool, or foam of synthetic resin.
May be configured.

In short, it is only necessary that the root of the plant can enter and the plant can take root. However, if the root body 1 is made of a synthetic resin foam,
Since it is inconvenient for construction and the like, it is preferable to use a flexible material such as a nonwoven fabric of a fiber because it can be bent.

Reference numeral 2 denotes a sheet-like hydrophilic material capable of absorbing water, for example, a nonwoven fabric or felt having a predetermined thickness in which copper-ammonium rayon fibers are entangled at a high density, or a woven or knitted fabric in which multiple layers are laminated. And can be bent in the same manner as the root attachment 1. By making the water-absorbable fibers dense, the hydrophilic body 2 has a function of transporting water by capillary action (hereinafter, referred to as "capillary action"),
The water absorbed by the hydrophilic body 2 by such a capillary action is
It is quickly diffused and transported to the entire hydrophilic body 2.

Particularly, cuprammonium rayon is a preferred material having a high capillary action because it has a hydrophilic group and has numerous infinite holes per fiber. In addition, since copper ammonia rayon is made of cellulose, it can be naturally decomposed by microorganisms and has an advantage that it is naturally decomposed after construction.

In the present invention, copper ammonia rayon is used in consideration of the above-mentioned capillary action and spontaneous decomposability. In addition, it has a water-absorbing action, such as a dense water-absorbing polymer fiber. A material with a capillary action,
A material that has a water absorbing effect and can be naturally decomposed may be used.

The point is that the hydrophilic body 2 should be composed of a material having at least water absorbency. Preferably, a material having a capillary action is used. More preferably, the hydrophilic body 2 is made of a naturally decomposable material. Is configured.

Reference numeral 3 denotes a base material accommodated in a bag 5 made of a net-like body, and includes a natural soil such as masasa soil mined from a mountain,
And artificial soil such as peat moss and bark compost. The base material 3 may be mixed with plant seeds as necessary.

The bag 5 is formed of a mesh, but is not necessarily limited to the mesh, and may be, for example, a thin woven or knitted fabric. In short, as long as the germinated plant can emerge from the bag 5 to the outside, it is not necessarily limited to a mesh.

In the present embodiment, the bag 5 containing the base material 3 is about 50 cm in length and width and about 10 cm in height.
, But is not limited to such dimensions. Further, the shape of the bag 5 may be, for example, a substantially cylindrical shape as shown in FIG. 2, or may be other shapes such as a substantially rectangular shape, a substantially inverted bowl shape, and the like. .

The vegetation floor forming tool 7 is provided on one side of the root body 1.
A hydrophilic body 2 is provided on 1a, and a plurality of bags 5 accommodating a base material 3 are provided on one side 2a of the hydrophilic body 2. The root body 1, the hydrophilic body 2 and the bag body 5 are connected to each other by sewing them with a thread or bonding them with an adhesive.

Next, a method of forming a vegetation floor using the vegetation floor forming tool 7 having the above configuration will be described with reference to the drawings. In FIG. 3, an adhesive 11 is applied at an appropriate interval to a construction surface 10 such as a concrete slope made of concrete constructed on the surface of the ground 8.

Along the construction surface 10, the vegetation floor forming device 7
When the other side 1b of the root body 1 is laid with the adhesive 11 facing, the vegetation floor forming tool 7 is fixed to the construction surface 10. At this time, at least a part of the hydrophilic body 2 among the members constituting the vegetation floor forming tool 7 is brought into contact with the water source 12. In the present embodiment, since the boundary between the concrete slope as the water source 12 and the ground 8 is located above the construction surface 10, the upper end side 2b of the hydrophilic body 2 is buried in the ground 8.

Here, the water source is, for example, the ground 8 on which no concrete is cast, as in the present embodiment.
It refers to “a place where water can be supplied to the hydrophilic body 2”. This is because the ground 8 is permeable to water and has a water pumping action, so that water can be supplied to the hydrophilic body 2 even if there is no pool of water on the surface of the ground 8. In addition, as an example of contact with a water source, a part of the hydrophilic body 2 may be brought into contact with the ground of a gap formed between structures such as concrete and blocks that are impervious to water, or a river, spring water, or the like. A part of the hydrophilic body 2 may be brought into direct contact with a place where water is abundant as described above.

With this operation, a vegetation floor is created on the construction surface 10 such as a concrete slope. In particular, since the adhesive 11 is used when fixing the vegetation floor forming tool 7 to the construction surface 10, the construction work is very simple.

Finally, by sprinkling water to promote germination, plants grow by obtaining water and nutrients from the base material 3, and the roots become entangled with the root attachment 1, and the concrete slopes are constructed. The greening of the surface 10 will be achieved.

That is, according to the conventional reclamation method, the plant can absorb only the water held by the base material. Therefore, a watering facility is separately provided, or concrete is removed to expose the ground. Unless the vegetation floor was formed after the plant was depleted, it was depleted and sufficient greening was difficult.However, according to the present invention, the hydrophilic body 2 retained the water of the water source 12 due to its water absorbing action, and produced a plant. Since water is continuously supplied to the roots, it is possible to prevent the depletion of plants even if there is no rainfall for a long period of time, and it is easier and more reliable to revegetate construction surfaces such as concrete slopes than conventional methods. Will be achieved.

Further, since the hydrophilic body 2 is made of a material having a capillary action, the water absorbed by the water source 12 to a part of the hydrophilic body 2 is quickly diffused by the capillary action, and the entire hydrophilic body 2 is diffused. And water can be supplied over a wide area of the vegetation floor. For example, when the area of the construction surface 10 is large and there is only one water source 12, the effect is remarkably exhibited. Water source
This is because the water of the water source 12 can be transported by the capillary action even to the portion of the hydrophilic body 2 that is very far from the water source 12.

Further, for example, when the vegetation floor is laid thick, it is preferable that the hydrophilic body 2 is made of a material having a capillary action. In such a case, since the hydrophilic body 2 is compressed by the weight of the vegetation floor, it is difficult to transport water by simply forming the hydrophilic body 2 with a material having only water absorbency, but the material also has a capillary action. This is because, if the hydrophilic body 2 is made up of water, water is transported over a wide area of the vegetation floor.

The vegetation floor creation method exemplified above uses a vegetation floor formation tool 7. For example, the root body 1 is bonded to the adhesive 11 along a construction surface 10 such as a concrete slope. After laying the hydrophilic body 2 on a part of which is in contact with the water source 12, the base material 3 is sprayed so as to cover the hydrophilic body 2, or the base material 3 May be laid by means such as storage. Even in such a method of forming a vegetation floor, the above-described effects are exhibited because water is supplied to the base material 3 by the water absorbing action of the hydrophilic body 2.

In the vegetation floor creation method exemplified above, when the vegetation floor creation tool 7 or the root attachment 1 is laid on a construction surface 10 such as a concrete slope, an adhesive 11 is used. Although it is fixed, it is not necessarily limited to the method of fixing using the adhesive 11, and may be fixed using, for example, an anchor. In short, it is sufficient to fix the vegetation floor forming tool 7 or the root attachment 1 to a construction surface 10 such as a concrete slope.

[0033]

As described above, according to the vegetation floor forming method of the present invention, the hydrophilic body absorbs water from the water source and supplies it to the base material. Without it, the plants will not be depleted. Therefore, unlike the conventional method, it is not necessary to separately provide a watering facility or to remove concrete, and it is possible to easily and surely green the construction surface such as a concrete slope that cannot retain water. Especially,
According to the vegetation floor forming tool of the fifth aspect, since the work is completed only by laying the forming tool on a construction surface such as a concrete slope, there is an advantage that it is extremely simple.

Further, if the hydrophilic body is made of a material having a capillary action, the water absorbed from a part of the hydrophilic body is quickly diffused, and It will be conveyed to the whole, for example, even if the construction area is large and there is only one water source, water will spread to a place very far from the water source, so the entire vegetation floor Greening can be achieved.

According to a third aspect of the present invention, the rooting body and the hydrophilic body of the vegetation floor forming tool are formed in a bendable sheet shape, and the base material is provided on the hydrophilic body in a state of being accommodated in the bag body. Then, since the vegetation floor forming device can be rolled or folded, there is an advantage that storage and transportation are simplified.
