BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation mat used for protecting and greening slopes and riverbeds.

[0002]

2. Description of the Related Art For example, as a means for protecting and greening a slope, a wire mesh lath is stretched on the slope and a spray base material made of a vegetation material containing plant seeds is sprayed on the wire mesh lath. In addition to installing a grid-like method frame along the method and slope, there is a means of arranging vegetation mats carrying plant seeds and sandbags containing soil in a bag with stretch grass in the section of the method frame. is there.

[0003]

However, in the method of spraying the vegetation material, it is necessary to use an apparatus for kneading the spray base material, a gun machine suitable for spraying, a mini cleat, etc. As it becomes, a lot of manpower is needed accordingly.

Further, according to the means using the sandbag, since the shape of the sandbag is regulated by the bag, the sandbag is difficult to fit on the uneven surface of the slope and has poor adhesion, and is housed in one sandbag. Since the amount of soil is as high as 20 kg, it is very difficult to work this soil in a high place, and the construction period is long.

The present invention has been made in consideration of the above matters, and an object of the present invention is to provide a vegetation mat exhibiting excellent functions in protection such as slopes and greening.

[0006]

In order to achieve the above object, a vegetation mat according to the present invention is provided with
A plate-like body in which a vegetation material containing at least plant seeds is filled in a bag made of a water-soluble material capable of germinating seeds is fixed to a mesh body at appropriate intervals.

In the second invention, a plate-like body made of a vegetation material containing at least plant seeds and a fiber material is fixed to the net-like body at appropriate intervals.

In the third invention, the plate-like body made of the fiber material is fixed to the net-like body at appropriate intervals, and
A vegetation material containing at least plant seeds is attached to the plate.

In any of the above vegetation mats, a fertilizer bag containing a fertilizer base material may be fixed between the plate-like bodies.

[0010]

[Function] The vegetation mat having the above-mentioned characteristic construction is completed, for example, only by laying it on the slope, and a large-scale device such as the conventional spraying of the spray base material and manpower associated therewith are not required, In addition, a foundation structure such as a law frame such as the laying of sandbags is not required, and revegetation work such as a slope can be performed very easily.

The vegetation mat laid on the slope is
While the net-like body protects the slope such as preventing rockfall, the plate-shaped body comes into close contact with the slope, and by germinating the plant seeds filled in the plate-shaped body, erosion is prevented and the plate By the fertilizer base material filled in the shape body or the fertilizer base material filled in the fertilizer bag provided between the plate-like bodies, the germinated vegetation can grow well for a long period of time.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

First, referring to FIG. 1 and FIG.
Reference numeral 1 is a hexagonal wire mesh as a mesh body, which is formed using a vinyl-coated iron wire having a wire diameter of 1.15 mm so that the mesh 2 is 26 mm. Reference numeral 3 is a plate-like body fixed to one surface of the tortoise shell 1 at an appropriate interval, and 4 is a fertilizer bag fixed so as to be located between the plate-like bodies 3 and 3.

As shown in FIGS. 3 and 4, the plate-like body 3 is a water-soluble material capable of germinating plant seeds, for example, a water-soluble material having excellent dispersibility in which narrow long fibers are bound by one entanglement. A vegetation material 6 containing at least plant seeds is filled in a bag body 5 made of a non-woven fabric, and the size thereof is, for example, about 100 to 150 cm × 30 to 50 cm × 2 to 3 cm. Fertilizers such as flower plant seeds, native plant seeds, and plant seeds 7 such as grass seeds, and fast-acting, slow-acting, and slow-acting fertilizers in appropriate proportions, such as vermiculite and perlite. Inorganic water retention agent,
Alternatively, it is mixed with a fertilizer base material 8 which is directly or indirectly necessary for plant growth, such as an organic water retention agent such as bark compost or peat moss.

Here, the flower plants include yellow daisies, French chrysanthemums, large daisies, chrysanthemums, saw grasses, fly squirrels, California poppies, purple nana, gypsophila, cosmos, keto, kawaranadeshiko, ginseng, and other native species. As a plant, wormwood,
Japanese pampas grass, Medohagi, wild grass and such as Japanese knotweed, red pine,
There are trees such as yashabushi, weasel, yamahagi, and komatsunagi. Then, the seeds 7 of these flower plants and native species plants may be appropriately selected and filled in the bag body 5 together with the fertilizer base material 8.

[0016] Further, as grasses, there are Gleeping Red Fescue, Highland Bentgrass, Red Top, Bermudagrass, Kentucky Bluegrass, etc., but these grasses have considerably higher growth potential than the above-mentioned flower plants and native plants. To grow flower plants and native plant and grass in a well-balanced manner on the construction target surface such as slope,
It is preferable to store seeds of flower plants or native plants and seeds of grass in separate bags 7. Furthermore, flower plants, wildflowers, and trees may be stored in the bag body 5 by type.

As shown in FIG. 3, the fertilizer bag 4 has a plate-like shape in a bag body 9 formed of an insoluble non-woven fabric having a thickness of 0.1 to 3 mm and an air permeability of 10 to 300 cc / cm / sec. It contains a fertilizer base material 10 similar to the fertilizer base material 8 contained in the body 3, and has a diameter of 2 to 3 cm and a length of 100 to 150 cm.

Then, the plate-like body 3 constructed as described above
And the fertilizer bag 4, as shown in FIG.
It is fixed by a stopper wire 11 at an interval of. In addition,
In FIG. 3, reference numeral 12 is a stopper such as a ringer for fixing the stopper wire 11 to the hexagonal wire mesh 1.

The vegetation mat M having the above structure is shown in FIG.
Although it is transported in a wound state as shown in Fig. 2, at the time of construction, if the vegetation mat M in this wound state is carried to a high slope, and the wound state is released at that position, It can be laid on the slope 13 as shown in FIG. In FIG. 5, 3A, 3B, 3C, and 3D are plate-like bodies in which tree seeds, wild grass seeds, flower plants, and grass seeds are mixed as plant seeds, respectively.

As described above, the vegetation mat M according to the above embodiment is laid on the slope 13, for example, to complete the greening work,
It eliminates the need for large-scale equipment such as the conventional spraying of the base material and the human labor associated therewith, and does not require a foundation structure such as a law frame such as the laying of sandbags. Greening work can be done.

The vegetation mat M laid on the slope 13
The turtle shell wire net 1 protects the slope 13 by preventing rockfall, while the plate-shaped body 3 comes into close contact with the slope 13. Then, after the vegetation mat M has been laid, part of the fibers constituting the plate-like body 3 is dispersed by absorbing moisture such as rainfall, and the plant seeds 7 and the fertilizer base material 8 fall from the inside, The plant seeds 7 germinate, and the germinating vegetation absorbs the fertilizer base material 8 and grows to prevent erosion on the slope 13. After that, the vegetation can be satisfactorily grown for a long period of time by the fertilizer base material 8 in the plate-like body 3 and the fertilizer base material 10 in the fertilizer bag 4 provided between the plate-like bodies 3.

In particular, when the vegetation mat M is constructed as shown in FIG. 5, it is possible to surely germinate and grow flower plants and native species plants without being pressed by pasture grass. Both flower plants and native plants and grass can be grown in a well-balanced manner, and desired greening can be achieved.

6 and 7 show another embodiment of the present invention. First, in the embodiment shown in FIG. 6, the plate-like body 3 is made up of a vegetation material 14 containing at least plant seeds and a fibrous material 15.
It consists of and. That is, as the vegetation material 14,
Using a mixture of the plant seed 7 and the fertilizer base material 8,
As the fiber material 15, a mixture of rock wool, coconut husk fiber, peat moss, bark, cotton, thread waste and the like is used, and after mixing these vegetation materials 14 and the fiber material 15, A suitable binder material is used to obtain a predetermined size.

Further, in the embodiment shown in FIG. 7, the plate-like body 3 is formed of a fiber material 16 similar to the above-mentioned fiber material 15 and a binder material, and the plate-like body 3 contains at least plant seeds. The vegetation material 17 is carried by a water-soluble adhesive such as polyvinyl alcohol.

It goes without saying that the embodiments shown in FIGS. 6 and 7 also have the same effects as the above-mentioned embodiments. Also in these examples, seeds of flower plants or native plants and seeds of grass are preferably arranged separately, and flower plants, wildflowers, and trees may be arranged by type.

In the above-mentioned embodiment, the plate-like bodies 3 and the fertilizer bags 4 are alternately arranged with respect to the hexagonal wire mesh 1.
The fertilizer bag 4 need not necessarily be formed in this manner, and when the fertilizer bag 4 is appropriately omitted, or when the plate-like body 3 is provided with a sufficient fertilizer base material 8, the fertilizer bag 4 is stopped on the tortoise shell 1. You don't have to wear it. Then, instead of the turtle shell wire net 1, other wire nets or other net-like bodies such as nets made of chemical fibers such as polyethylene may be used. Furthermore, it goes without saying that the vegetation mat M according to the present invention may be used for greening other than the slope 13.

[0027]

[Effects of the Invention] As described above, the vegetation mat according to the present invention has the same effect as the method of spraying thick subsoil by completing the greening work just by laying it on the construction target surface. This eliminates the need for large-scale equipment such as conventional spraying of sprayed base material and the accompanying labor, and does not require a foundation structure such as a sandblast laying method to make the slope surface extremely easy. You can do greening work such as.
