DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lawn frame for reinforcing a slope, and more particularly to a method for forming a greening lawn capable of greening the slope.

[0002]

2. Description of the Related Art Conventionally, as a greening method frame capable of greening, reinforcing bars for a legal frame are arranged in a grid pattern on a net stretched on a slope, and along the reinforcing bars. It is known that a law frame is formed by installing a gaddender form member and spraying concrete, and then spraying a vegetation base material to a predetermined thickness in a recess surrounded by the law frame.

[0003]

However, in the greening method frame, concrete is sprayed before the vegetation base material is sprayed into the concave portion to form the method frame.

[0004] Therefore, when spraying concrete, a dirt prevention sheet must be stretched in the concave portion and further removed.

In addition, it is necessary to provide a gaddender frame material having a special shape in order to form a legal frame.
After forming the legal framework, the vegetation base material is sprayed, so a holding material such as glue must be blended into the vegetation base material,
It is disadvantageous in terms of work efficiency and economics. Furthermore,
Even if a holding material such as glue is added to the vegetation base material, it is not permanently retained, and the decline of the plant cannot be avoided. Therefore, in order to achieve vegetation before the vegetation base material flows out, a large number of fast-growing herbaceous seeds are mixed and germinated, so that the herbaceous plants are pressed by the herbaceous plants to cause damage, and Greening cannot be achieved.

The present invention has been made in view of the above circumstances, has no difficulty in operation, does not require a special member or a holding material such as glue, or requires a small amount and is economical. The present invention also provides a method for forming a greening method frame in which a vegetation base material is permanently stable and a woody plant can be introduced from the beginning.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a method in which each frame is surrounded by a slope forming portion in which reinforcing bars are arranged in a grid pattern on a net stretched on the slope. Then, stretch the root extensible sheet without hindering germination and growth with the surplus part contained in the legal frame forming part, spray the vegetation base material containing seeds and cover it with the surplus part of the sheet A mat-shaped green body was formed, and concrete was sprayed on a law frame forming part existing around the mat to form a legal frame.

According to the present invention, when the vegetation base material is sprayed, the legal frame forming portion including the reinforcing bar is covered with the surplus portion of the sheet stretched on the legal frame, so that the vegetation base material may be contaminated. There is no.

[0009] The green plant wrapping the vegetation base material is mat-shaped and is not scoured, is held semi-permanently on the slope, and can be used for planting woody plants without incorporating herbaceous plant seeds. Can be vegetated.

[0010] Further, since the green body itself can be used as a substitute for a mold for forming a legal frame, it does not require special parts and is economical.

Still further, a U-shaped spacer for securing a legal frame size is arranged at least around a part of the green body,
Alternatively, when the corrugated cardboard is arranged inside or outside the periphery of the green body, it is possible to cope with a case where it is difficult to secure the size of the legal frame due to, for example, the uneven shape of the slope.

[0012] In addition, a soil material is attached to a part of the surface of the green body, and concrete is sprayed on the soil material, or a concrete mixed with a reinforcing material is sprayed on a part of the surface of the green body. In this case, it can be permanently held on the slope.

[0013] In the above invention, each vertical frame of a slope forming section in which reinforcing bars are arranged in a grid pattern on a mesh body stretched on the slope,
When a strip-shaped sheet that does not hinder germination and growth is stretched over the horizontal frame with the surplus part being accommodated in the lawn frame forming part, the formed green body has an opening on the bottom surface, so the sheet is in each law frame. Because it is not covered, there is no need to use a special sheet capable of elongating the roots, so that it is economical and the construction is simple.

[0014]

Next, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 to 6 show an example of the preferred embodiment of the present invention. First, as shown in FIG. 1, weeds and the like growing on the slope 1 are removed and dust and the like are removed. Clean and level the surface.

Next, as shown in FIG. 2, a net 2 such as a diamond-shaped wire mesh is fixed and stretched on the surface of the slope 1 with, for example, an anchor 3 and the slope forming portion 4 on the net 2 is formed. The reinforcing bars 5 are arranged in a grid pattern having an interval of, for example, about 1000 mm to 1500 mm along the line, and germinated in each concave portion 6 surrounded by the legal frame forming portion 4 as shown in FIG. A sheet 7 made of a light-shielding sheet such as a Russell knitted sheet having a predetermined size that allows the roots of the plant to grow without inhibiting growth is formed by, for example, rounding or shrinking a surplus portion 71 extending vertically and horizontally. It is stretched while housed in the forming section 4.

Next, as shown in FIG. 4, a seed-containing vegetation base material 8 is placed on a sheet 7 stretched in a concave portion 6 to a predetermined thickness, that is, a thickness substantially equal to the height of a legal frame to be formed later. Spray it. At this time, since the legal frame forming portion 4 is covered with the surplus portion 71 of the sheet 7, there is no concern that the reinforcing bar 5 or the like arranged is contaminated, and it is not necessary to cover the reinforcing bar 5 with another sheet as in the related art.

Then, as shown in FIG. 5, a surplus portion 71 previously stored in the legal frame forming section 4 is expanded to a predetermined legal frame forming section 4.
If necessary, the vegetation base material 8 is covered from above and below and from the left and right to form a mat-shaped green body 9 and the legal frame forming portion 4 having a predetermined width and a predetermined height is exposed therearound. . At this time, the shape of the green body 9 can be appropriately determined according to the situation of the local ground.

Further, as shown in FIG. 6, concrete is sprayed on the legal frame forming portion 4 existing around the green body 9 to form the legal frame 10.

According to the present embodiment, the green body 9 is
Since it acts as a mold for forming a zero, it does not require a special mold such as a conventionally used gaddender mold material, and is economical and easy to construct.

Further, in this embodiment, since the vegetation base material 8 is wrapped in the sheet 7 to form a mat, there is no need for a bonding material such as a glue material, and there is a fear that the vegetation base material 8 is scoured due to rainfall or the like. In addition, only woody plants can be germinated and grown, so that pressure from herbaceous plants does not matter.

FIG. 7 shows a different embodiment of the present invention. As shown in FIG. 5, when concrete is sprayed on the legal frame forming portion 4 around the green plant 9, the green plant 9
A U-shaped spacer 11 is set around the part (FIG. 7A),
After that, concrete is sprayed on the legal frame forming section 4 to form the legal frame 1
0 (FIG. 7B).

In this embodiment, in order to secure the dimensions and shape of the green body 9, the entire periphery thereof is formed of four U-shaped spacers 1.
Although it is surrounded by 1, it may be arranged in a part (not shown). Further, as the U-shaped spacer, a spacer formed of a wire net or a synthetic resin material can be used.

FIG. 8 also shows another embodiment of the present invention. For example, a water-resistant corrugated cardboard material 12 is bent into an L-shape or a U-shape to form a shape 12 inside the sheet 7 (see FIG. 8A), or It can be arranged on the outside (see FIG. 8B) to ensure accurate legal frame dimensions. In this case, the material cost is low and economical, and the workability is excellent due to its light weight.

FIG. 9 shows still another embodiment of the present invention, in which a soil material 13 such as a wire mesh is installed or inserted into a part of the surface of the green body 9, and the soil material is provided. 13 is a method of spraying concrete or a concrete in which a reinforcing material such as a fiber reinforcing material is mixed into a part of the surface of the green body 9 to stabilize the vegetation base material permanently on the slope. Not only is it possible, but also a large amount of fallen leaves can be captured to promote greening circulation.

FIGS. 10 to 12 show an example of a different embodiment of the present invention, which is roughly the same as the embodiment of the present invention. In the embodiment, each concave portion 6 surrounded by the legal frame forming portion 4
Inside, the sheet 7 is stretched in such a manner that a surplus portion 71 extending up and down and right and left is accommodated in the legal frame forming section 4 by, for example, being rounded or contracted. As shown in FIG.
4 is a vertical frame 41 of the slope forming section 4 located on each side of the frame 6
Then, each of the horizontal frames 42 is stretched so as to include a surplus portion 141, and then, as shown in FIG. Sprayed to a thickness substantially equal to the frame height, and thereafter, as shown in FIG.
The green body 9 having the opening 91 on the bottom surface is formed so as to cover the vegetation base material 8 from above and below and from the left and right so as to form the predetermined legal frame forming portion 4 by expanding the surplus portion 141 of the 4.

According to the embodiment of the present invention, when the vegetation base material 8 containing seeds is blown into the recess 6, the legal frame forming portion 4 is formed.
Is covered with the surplus portion 141 of the sheet 14 so that there is no fear that the reinforcing bar 5 and the like arranged in the same manner as in the above embodiment are contaminated.
Since the greening body 9 having 1 is formed, the inside of each legal frame is not covered with a sheet, and it is not necessary to use a special sheet capable of elongating the root, so that it is economical and the construction is simple.

[0028]

As described above, according to the present invention, since the green plant functions as a mold for forming a legal form, it does not require a special form which has been conventionally used, and is economical and workable. Is easy and the vegetation base material is wrapped in sheets to form a mat, so there is no need for glue or other bonding material, and there is no need to worry about scouring due to rainfall. It can germinate and grow, so there is no problem of pressure by herbaceous plants.

Particularly, since the vegetation base material is wrapped in a sheet and has a mat shape, the vegetation base material does not require a bonding material such as a glue material. There is no need to worry about scouring and only the woody plants can germinate and grow, so there is no problem of pressure by the herbaceous plants. In addition, the shape of the green body can be appropriately determined according to the situation of the local ground, and when spraying a seed-containing vegetation base material, the legal frame forming part is covered with an excess portion of the sheet. Therefore, there is no need to worry about contamination of reinforcing bars and the like, and it is not necessary to cover the reinforcing bars with another sheet as in the conventional case.

Further, when concrete is sprayed on the lawn frame forming part, a U-shaped spacer is installed around the green body, and then concrete is sprayed on the lawn frame forming part to form a legal frame. Thus, a method frame having excellent dimensional accuracy can be formed.

Further, when a U-shaped spacer formed by bending a water-resistant corrugated cardboard material is disposed inside or outside a sheet, a method frame excellent in dimensional accuracy can be easily formed at low cost.

In addition, when the concrete is sprayed on the soil retaining material attached to a part of the surface of the green body, or when the concrete containing the reinforcing material is sprayed on the part of the surface of the green body, the vegetation base material may be used. Can be permanently stabilized on the slope, and a large number of fallen leaves can be captured by a green body to promote greening.

Further, in the case where a belt-like sheet is stretched on a slope forming portion in which reinforcing bars are arranged in a grid pattern on a mesh body stretched on the slope, with a surplus portion accommodated in the law frame forming portion. Since the sheet does not cover the inside of each frame, there is no need to use a special sheet capable of elongating the roots, so that it is economical and easy to construct.
