It is possible to thereby to prevent the base material 17 from being carried away by increasing the resistance of the main body 1 by positioning the net 2 nearly in the center of the base material 17.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a net-like body for retaining a vegetation base material (hereinafter simply referred to as a net-like body) used, for example, in a slope greening method.

[Prior art] One of the above slope greening methods is shown in Figures 6 (A) and (B).
), two sheets of seven knots made of chemical material are overlapped to form, for example, portions of about 5 cm at intervals of 30 to 50 cm that are not woven or fused to each other to form the housing portion 3.
1, and a fertilizer base material 34 directly or indirectly necessary for plant growth, such as fertilizer, soil conditioner, water retention agent, etc., is formed in a bag 33 made of a corrosion-resistant non-woven fabric. A net-like body 36 containing the fertilizer base material bag 35 and containing the fertilizer base material bag 35 in the storage section 31 is
After setting the seed on the slope 39 using anchors 37, pegs 38, etc., the vegetation base material 40 containing seeds, chemical fertilizer, soil conditioner, water retention agent, etc. in gel form is placed in a net-like structure. 3
There is a method of spraying from above No. 6 to an appropriate thickness depending on the machine.

According to this construction method, the net-like body 36 prevents the vegetation base material 40 from being washed away, and the seeds contained in the vegetation base material 40 germinate and grow as plants at an early stage.
Fertilizer in the vegetation base material 40 and fertilizer base material 3 in the fertilizer base material bag 35
4 is appropriately supplied, plants can be reliably grown on the slope 39 where it has been difficult for plants to grow.

[Problem to be solved by the invention]

By the way, in recent slope greening construction methods, there is a tendency to spray the vegetation base material 40 thickly, for example, 3 to 5 cm, and in such construction methods, it is difficult to prevent the vegetation base material 40 from washing away. In view of this, it is desirable that the upper surface side of the net-like body 36 be located approximately in the middle of the vegetation base material 40. Because the two nets are almost tightly integrated in the area, there is no thickness, and as a result, as a result of being too close to the slope 39, the effect of preventing the original painting and the vegetation base material 40 from being washed away by frost heaving is weak. There is.

On the other hand, it is possible to reduce the mesh size of the net-like body 36, but in this case, even if the vegetation base material 40 is sprayed from above the rope-like body 36 by a machine, the vegetation base material 40 will be This has the disadvantage that it becomes difficult to pass through the rope, making spraying work that much more time-consuming.

By the way, one of the main purposes of applying greening methods to slopes is to restore the slope to its original appearance, and the aesthetic appearance of flowers is also required, but if only local plants such as wildflowers and trees or flowers are used, the slope cannot be renovated. Therefore, in the past, the vegetation base material 40 sprayed onto the slope 39 includes foreign plants such as grasses in addition to the above-mentioned native plants or flowers. The vegetation base material 40 mixed with exotic plants was sprayed onto the net-like body 36 using a machine.

However, the above-mentioned native plants and flowers germinate and grow slower than foreign plants, and are not able to grow sufficiently due to pressure from foreign plants, resulting in greening of only foreign plants. However,
Non-native plants grow quickly but die within a short period of time.
In the end, the greening is short-term, and there is a problem that the greening of the slope cannot be maintained permanently.

The present invention has been made with the above-mentioned considerations in mind, and its purpose is to reliably prevent the washing away of vegetation base material that has been thickly sprayed onto a slope;
To provide a net-like body that can efficiently spray vegetation substrates and also that can ensure the germination and growth of native plants and flowers such as wildflowers and trees without being overwhelmed by foreign plants such as grasses. be.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the present invention, a housing portion is provided between the two nets of the net structure main body having a double net structure in which a front net and a back net are overlapped. In the net-like body for holding vegetation base material formed in the horizontal direction, the mutually opposing warp threads of both the nets are stitched every other row or every few rows, and the fertilizer base material is stored in a bag in the storage part. It houses a fertilizer base material bag and a vegetation bag containing vegetation seeds inside the bag.

[Function] In the rope-like body having the above structure, when the fertilizer base material bag and the vegetation bag are stored in the storage part and stretched on a slope, the stitched parts in every other row will be Since it forms a three-layer structure together with the net and the Hanknet, the thickness of the part other than the housing part of the net increases accordingly. Since the mesh body has a large resistance to the material, it is possible to reliably prevent the vegetation base material from being washed away.

Further, the mesh size of the mesh does not need to be made smaller than necessary, but can be made larger than that of conventional meshes, so that the vegetation base material can be sprayed efficiently.

Then, in the storage section S, for example, a fertilizer containing a fertilizer base material in a bag! /4 A base material bag and a vegetation bag containing alien plant seeds as vegetation seeds are stored in the bag, while local plants such as wildflowers, trees, and flowers are contained in the vegetation base material that is sprayed onto the slope. By inserting seeds and spraying this vegetation base material onto the slope, local species of plants can grow together with exotic plants, permanently maintaining the greenery of the slope and improving its aesthetic appearance. be able to.

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

1 (A) to (C) show an example of a wire-like body N according to the present invention, in which 1 is a net-like body main body with a double net structure, a front net (upper net) 2 and a back net (lower net). ) 3, and a plurality of accommodating portions 4 formed at appropriate intervals between the two. The mesh size of both nets 2.3 is approximately 1 inch (2.54 cm) in length and width. In addition, in FIG. 1(A), 5 is a reinforcing rope.

The structure and manufacturing method of the net body body 1 will be explained in more detail with reference to FIGS. 2 and 3. In the front net 2, as shown in FIG. It is formed by chain-knitting a monofilament made of polyethylene (PE) yarn, and the weft 7 perpendicular to this is formed by knitting, for example, 1500 denier OPE yarn in a zigzag manner between two adjacent warp yarns 6. It is. Also, Banknet 3
As shown in FIG. 2, the warp threads 8 are formed by chain-knitting monofilaments made of, for example, 800 denier PE threads, and the weft threads 9 orthogonal thereto are made of monofilament threads made of, for example, 1500 denier OPE threads. 9A and a flat yarn (for example, 2.5 mm in width and 49 μm in thickness) 9B made of polypropylene (PP) yarn of 1000 denier are knitted in a zigzag manner between two adjacent warp yarns 8.

These front net 2 and back net 3 are
As shown in FIG. 3, the warp threads 6 and 8 are knitted together at appropriate intervals, leaving unknitted parts to form the mesh body 1 having a double net structure, and the unknitted parts (
For example, 3 stitches) are formed in the housing part 4, and the opposing warp threads 6.8 of both nets 2.3 are bound every other row with a binding thread 10 made of monofilament made of 800 denier PE thread. It's a combination. In this binding, the binding thread 10 is used to bind, for example, 5 stitches of the warp threads 6.8, and is inserted into any of the warp threads 6.8 in the storage section 4, leaving the binding section open (see Fig. 1). (A),
(See (B) and (C)). The weight of the net-like body N configured in this way is 78.5 g excluding the reinforcing rows 15.
/Po is.

Referring again to FIG. 1(A), reference numerals 11 and 12 denote a fertilizer base material bag and a vegetation bag, respectively, which are housed and held in the housing section 4. The fertilizer base material bag 11 is made of xi-resistant and insoluble nonwoven fabric that is thick and breathable so that fertilizer nutrients gradually ooze out due to rainfall, etc., and contains fertilizers, soil conditioners, water retention agents, etc. It contains fertilizer base materials directly or indirectly necessary for growth. In addition, the vegetation bag 12 does not interfere with the germination and growth of vegetation, and is made of a polymeric film or starch film that dissolves in water, or a water-soluble paper with cheesecloth (for example, Ponric (trade name): Ikeda Shigyo Co., Ltd. The grass seeds are stored in a bag made of Grass seeds include Greeping Red Fescue, Highland Bentgrass, Red Tonose, Bermuda Grass, and Kentara Key Bluegrass, etc., and these can be selected as appropriate and stored in the bag. Water retaining material and some fertilizer may also be contained in the container.

When spraying the vegetation base material onto the slope, first, as shown in FIG. 1(A) and FIG. Insert and attach it, and attach it to the back net 3gI using anchors 13 and pegs 14! The vegetation bag 12 is stretched so that it is close to the slope 15, and the vegetation bag 12 is located above the fertilizer base material bag 11. In this case, as shown in Figure 4,
Since the stitching portions 16 stitched together every other row form a three-layer structure together with the front net 2 and the back net 3, the thickness of the portion of the string-shaped body N other than the housing portion 4 increases accordingly.

After the three-layer structure N is stretched on the slope 15, a vegetation base material made into a gel by mixing seeds, organic matter, chemical fertilizers, soil conditioners, water retention agents, etc. is added to the rope. The seeds used at this time are:
Yellow daisies, French chrysanthemums, large brocade chrysanthemums, sawweed, and dianthus.

California Bopy, Purple Banana, Gypsophila
There are seeds of flowers such as cosmos, celosia, dianthus dianthus, and daikon daisy, seeds of wild plants such as mugwort, Japanese pampas grass, and itadori, and seeds of trees such as red pine, shabu, japonica, yamahagi, and komatsunagi. , these may be selected as appropriate.

Then, this gel-like vegetation base material is sprayed onto the net-like body N using a machine to a thickness of, for example, 2 to 5 cm. In addition, in FIG. 4, 17 indicates the sprayed vegetation base material.

In this case, even if the vegetation base material 17 is sprayed thickly on the slope 15, the front net 2 will be located approximately in the center of the sprayed vegetation base material 17, as shown in FIG. Therefore, the resistance of the net-like body N against the vegetation base material 17 becomes large, and the flow of the vegetation base material 17 can be reliably prevented. In addition, there is no need to make the mesh size of the rope-shaped body N smaller than necessary, and in fact, it can be made larger than conventional ones, so the vegetation base material 17 can be sprayed efficiently, and the vegetation base material 17 can be sprayed more efficiently. Slope 15
It can be placed in close contact with the

Thus, on the slope 15, the grass in the vegetation bag 12 housed in the housing part 4 of the rope N is fast growing, and the grass grows in stripes to protect the slope 15. In other parts of the network N, wildflowers, trees, and flowers germinate from the sprayed vegetation base material 17, but because they are far away from the grass, they can grow without being pressured by the grass. 15
The entire area will definitely be greened.

The present invention is not limited to the above-mentioned embodiments. For example, when the mesh of the rope-like body 1 is relatively small, the warp threads 6.8 of the front net 2 and the back net 3 facing each other may be used.
may be stitched together every several rows (for example, 2 to 3 rows), and the configuration of both nets 2.3 can be set arbitrarily; for example, both nets 2.3 may be made to have exactly the same configuration. Alternatively, the flat yarn 9B may be provided only on the front net 2 side, and only the monofilament 7 may be provided on the bank net 3 side.

Furthermore, the mesh sizes in both nets 2.3 do not necessarily have to be the same, and may be different from each other.

Further, in the above-described embodiment, seeds of exotic plants such as grasses are stored in the vegetation bag 12 stored in the storage part 4 of the net-like body N, and the constituent members of the vegetation base material 17 are sprayed onto the slope surface 15. Instead, we use seeds of local plants such as wildflowers and trees, as well as flower seeds.
Seeds of native plants and flowers may be stored in the container 2, and seeds of exotic plants may be used as constituent members of the vegetation base material 17.

The vegetation base material 17 is not limited to the above-mentioned gel-like material,
It may also be a so-called dry method that does not use water, in which seeds, organic matter, chemical fertilizers, soil conditioners, and water retention agents are simply sufficiently mixed.

In the above-mentioned embodiment, a gel-like (or dry) vegetation base material 17 is applied from above the net-like body N laid on the slope surface 15.
However, the net-like body N according to the present invention
can also be used for construction methods other than this one,
For example, it can also be used in a construction method in which the vegetation base material 17 is not sprayed onto the net-like body N, and this will be explained with reference to FIG. 5.

That is, FIG. 5(A) shows a structure in which only the rope-like bodies N are laid on the slope 15, and in this example, the fertilizer base material bags 11 and the fertilizer base material bags 11 are placed in every other storage section 4A. , California bopy, purple banana, gypsophila, cosmos,
A vegetation bag 12A containing appropriately selected seeds of annual flowering plants such as celosia and other annual flowering plants, and seeds of perennial flowering plants such as Celosia dianthus, Acadian chrysanthemum, Sawtooth grass, French chrysanthemum, and Okinawa chrysanthemum, etc., is stored therein. In the housing section 4B, there are Kentucky bluegrass, Hammuda grass,
A vegetation bag 12B containing appropriately selected grass seeds such as Olympinoctol fues is stored therein.

In the case shown in FIG. 4B, a layer 19 of thin cotton on which seeds 18 of an annual flowering plant have been scattered and sown is attached to the net-like body N, while a fertilizer base material bag 11 is placed in the storage part 4^. and a vegetation bag 12C containing seeds of perennial flowers and plants, and a net-like body N which contains a vegetation bag 12B containing grass seeds in the storage part 4B. It is laid out so that it is close to.

In addition, in the case shown in the same figure (C), a thin cotton layer 19 on which seeds 20 of annual flowering plants and perennial flowering plants are scattered and sown.
is attached to the net-like body N, while the fertilizer base material bag 11 and the vegetation bag 12B containing grass seeds are stored in the storage part 4A, and the fertilizer base material bag 11 is stored in the storage part 4B. The net-like body N is laid down so that the layer 19 is close to the slope 15.

Furthermore, in the case shown in FIG. 1D, a thin cotton layer 19 on which grass seeds 21 have been scattered and sown is attached to the rope N, while a fertilizer base material bag 11 and a The layer 19 is close to the slope 15, and the net-like body N is formed by accommodating a vegetation bag 12A containing seeds of annual flowering plants and perennial flowering plants, and accommodating a fertilizer base material bag 11 in the accommodating part 4B. It is laid out so that it will be.

Also, in the one shown in the same figure (E), grass seeds 2
A layer 19 of thin cotton having been sprinkled and sown with the fertilizer 1 is attached to the rope-shaped body N, while a fertilizer base material bag 11 and a vegetation bag 12C containing seeds of perennial flower plants are accommodated in the accommodating part 4A. , a vegetation bag 12 containing seeds of annual flowering plants in the storage section 4B.
0 is laid down so that the layer 19 is close to the slope 15.

[Effects of the Invention] Since the present invention is configured as described above, it is possible to reliably prevent the vegetation base material that has been thickly sprayed onto a slope from being washed away due to rain or frost heaving. In addition, since there is no need to make the mesh size smaller than necessary, the vegetation base material can be sprayed smoothly, construction efficiency is improved, and the quality of slope greening can be improved.

According to the present invention, native plants and flowers such as wildflowers and trees can be reliably germinated and grown without being overwhelmed by foreign plants such as grasses.
