DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation net for vegetation and a vegetation base for use in, for example, a slope revegetation method.

[0002]

2. Description of the Related Art Hitherto, a greening method has been applied to a slope on a hillside formed for road construction, land development, or the like in order to protect the landscape and maintain the landscape. As one of the greening methods, a vegetation net consisting of warps and wefts is stretched on the slope using anchors or pegs, and
There is a greening method in which a vegetation base material including a plant seed containing an organic compost, a chemical fertilizer, a vegetable fiber, a water retention agent, a soil improving material, etc. is sprayed so as to cover the net.

Alternatively, a vegetation net having a bag storage section at an appropriate interval in the warp direction is used, and a storage bag of vegetation material is stored in the bag storage section to form a vegetation base. There is also a greening method in which a plant material mixed with plant seeds is sprayed so as to be stretched on the slope and cover this net. In the greening method using these methods, the vegetation base sprayed on the slope is used. The timber is involved in the eyes of the vegetation net,
It is said that the runoff of the vegetation base material is effectively prevented.

[0004]

However, although the layers of the vegetation substrate sprayed on the slope are connected to each other through the eyes of the net, they are practically divided into two parts by the net. And, although the vegetation base layer on the lower side of the net is restrained by the slope and the net,
When a gap is formed between the base material layer and the slope, the vegetation base material or the slope surface soil may flow in that portion. Also, in order to firmly prevent the vegetation net from slipping, a large number of anchors and pegs were required.

On the other hand, since the vegetation base material layer on the upper side of the net is only in a state of riding on the two-dimensional flat net, cracks are generated by drying, and the vegetation base material layer is caused by strong rainfall. The layers could be washed away.

Another problem is that a vegetation net having a bag storage portion for forming a vegetation base for greening has conventionally used a double net, and a weft and a weft are inserted between the double nets. Form a bag storage part so that it becomes parallel,
As shown in Japanese Patent Application Laid-Open No. 6-185061, a single (single) net is used, and a part of the warp is sunk on one side of the net so that the net is parallel to the weft. However, in the above-described means, since a double net is used, many yarns, which are materials for manufacturing the net, are required, and the manufacturing process is complicated. For example, there is a problem that the production cost increases.

In the above-mentioned means, although there is no problem as in the means described above, the holding of the vegetation material holding bag in the vegetation net is not always reliable because the bag for storing the vegetation material only sunk the warp of the net. In addition, there is also a problem that it is difficult to store the vegetation material storage bag in the bag storage section.

[0008] The present invention has been made in consideration of the above-mentioned matter, and is provided with a vegetation net having a function of preventing slippage of a net and a vegetation base material, a flow of a slope surface soil, or a vegetation base material layer on a net. It is an object of the present invention to provide a vegetation net capable of three-dimensionally maintaining the vegetation net. In addition, a vegetation net having a bag storage portion is simple in configuration, inexpensive in cost,
Moreover, it is an object of the present invention to provide a vegetation material storage bag that can be easily and reliably stored. It is another object of the present invention to provide an inexpensive vegetation substrate for greening using the vegetation net.

[0009]

Means for Solving the Problems In order to achieve the above object, according to the first invention, as a vegetation net for greening, a back side which is a slope side of a single net knitted and woven by warps and wefts. In order to form a loop with the back side which is the slope side, a weft yarn different from that for net weaving is knitted at appropriate intervals in the weft direction of the net, and the net of this knitted weft is Are used as locking members.

[0010] In vegetation net above arrangement, the weft direction of the locking member liberated from the net slope vegetation net
Since the let provided in the rear surface portion serving as a side, which by engaging the like gravel exposed to slope, to exhibit a function of the displacement prevention vegetation net, also for the sprayed vegetation substrate, Even if it flows, it is caught and entangled by the locking member, and also on the slope of the slope, by entanglement with the locking member, it is possible to prevent them from flowing out.

Alternatively, in the case where the weft-direction locking members separated from the net are provided on both the front and back surfaces of the vegetation net,
It goes without saying that the following effects are synergistic with the above effects. That is, since the vegetation base material is entangled with the locking member on the surface of the vegetation net, the vegetation base material is three-dimensionally held by the locking member and the net, and the vegetation base material on the upper side of the net is provided. It is possible to prevent the layer from being cracked due to drying, and the vegetation base layer from being washed away due to strong rainfall or the like.

The vegetation net for greening according to the second invention comprises a single net knitted by a warp and a weft, and a bag storage portion for storing a vegetation material storage bag is knitted and woven. In order to form a double structure with a single net, a warp and a weft different from those for net knitting are knitted at appropriate intervals in the warp direction of the net, and this knitted portion and the single net With the portion, a bag storage portion having a double net structure continuous in the weft direction is formed, and a loop is formed on the back surface of the single net with the back surface, so that it is different from that for net weaving. Are knitted at appropriate intervals in the weft direction of the net, and the portion of the knitted weft separated from the net is used as a locking member.

In the vegetation net having the above-described structure, a bag storage portion is formed by weaving a single net with a warp and a weft different from those for net weaving, thereby making the vegetation net itself substantially single. Therefore, in addition to having the above-mentioned effects, the configuration of the vegetation net is simple, easy to manufacture, and inexpensive. In addition, since the bag storage section is configured to be continuous in the weft direction of the net, the storage of the vegetation material storage bag in the bag storage section is easy, and the storage bag is securely held.

In order to form a bag storage section in a single net,
For example, when weaving a single net, a plurality of net weaving warp yarns in the weft direction are hooked and connected to the bag storage unit knitting warp, respectively, so as to form a warp group with them. Are connected in a mesh shape by the first weft for weaving of the bag storage unit, and the end warps for the weaving of the bag storage unit in one weft direction of each group are added to the bag. When the second weft for the weaving of the storage section is entangled and the single net is knitted and woven in a predetermined manner, the hooking connection between the warp yarns is stopped and further knitting of the single net is continued for a predetermined number of nits. Then, during the continuous weaving, the second weft entangled with the end warp is repeatedly jump-connected to the warp entangled with the end warp of the next warp group, so that the jump-connected second warp is formed. With weft The first weft coupled thread in a mesh shape, and, by a single net portion faced each other to,
A bag storage portion that is continuous in the weft direction can be formed in a non-connection portion between warps.

In order to form the locking member on the vegetation net provided with the bag storage portion, after the above-mentioned continuous weaving of the further net, the knitting between the predetermined meshes of the single net connecting the warps with each other. As appropriate, a second weft entangled with the end warp is repeatedly jump-connected to the end warp of the adjacent warp group and the warp entangled with the second warp so as to form a loop with the single net surface portion, An engaging member can be formed by a jump portion released from the net of the knitted weft.

Alternatively, the second weft for the weaving of the bag storage section is entangled with the end warp for the weaving of the bag storage section on both sides in the weft direction of each group, and the second weft is entangled. By repeatedly jump-joining the warp and the end warp of the next warp group, the bag storage portion and the locking member can be formed in a state where the second weft is crossed, that is, The vegetation net provided with the bag storage portion and the string-like weft can be easily and inexpensively manufactured only by appropriately jump-connecting the weft yarns for the storage portion weaving.

The vegetation substrate for greening according to the present invention is formed by storing a vegetation material storage bag in the bag storage portion having the above-described configuration. A vegetation base which can have a slip prevention function, a slope surface soil, and a vegetation base holding function can be provided at a low cost by ensuring that the vegetation material storage bag can be held.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 (A) shows a vegetation net 1 for greening.
(B) shows the back side.

This vegetation net 1 is used for a greening method in which a vegetation base material 2 containing plant seeds is sprayed on a slope N as shown in FIG. 8, for example. Is the surface on the side of the extension to the slope N.

As shown in FIG. 2, the vegetation net 1 for greening is used for weaving the single net 5 with the warp 3 and the weft 4 at a suitable interval in the warp direction. On the back surface, a locking member 6 is formed so as to form a loop with this surface. The material of the warp 3 and the weft 4 is excellent in corrosion resistance, such as polyethylene or polypropylene. Use the following materials in addition to conventional materials, such as garments, vegetable fibers such as hemp and jute, or those that corrode in a relatively short period of time, such as viscose rayon. Can be.

That is, there are strong rayon, various preservative-treated corrosive materials (these materials and vegetation nets using the same are disclosed in Japanese Patent Publication No. 6-99918), Blended fiber consisting of synthetic fibers and synthetic fibers, or mixed fiber rayon in which at least one of a polymer emulsion or a water-soluble polymer is internally added to a viscose solution (vegetation net using these materials and vegetation net using the same) As for Japan
No. 4, No. 4), and other materials such as fibers made of biodegradable bioplastic, which can adjust the corrosion time, can be suitably used.

An example of a procedure for manufacturing the vegetation net 1 provided with the locking member 6 will be described with reference to FIGS. 3 to 5. As the warp 3 for net weaving, for example, polyethylene is used.
The vegetation net 1 is knitted by a Raschel loom as follows using a monofilament of about 00 to 2000 denier and a tape-like flat yarn of about 300 to 3000 denier made of, for example, polyethylene as the weft 4.

That is, the size of the mesh is 15 mm × 15 m
m, weaving a vegetation net 1 having a width of about 100 cm in the weft direction. First, a chain yarn obtained by chain-knitting several monofilaments is used as a warp 3 for net knitting, and 65 of these yarns are spaced at 15 mm intervals. Then, the weft 4 for net weaving made of flat yarn is sequentially entangled with this,
The single net 5 is knitted with a size of × 15 mm.

At the time of weaving the single net 5, two net knitting warps 3A, 3A for one mesh at the end.
From now on, two net knitting warp yarns 3A, 3A for each meshing unit are specified every six meshes, and the warp yarns 3A, 3A are formed with the net knitting yarns so as to form a warp group therewith. Is hooked and connected with another warp 3B, 3B for weaving a locking member made of, for example, a monofilament, and as for the warp 3B, 3B of each warp group, these are first wefts 4A for weaving a locking member made of, for example, a flat yarn. To form a stitch.

On the other hand, except for the warp group on one end side, a second weft 4B for weaving of a locking member made of, for example, a flat yarn is shown in FIG. 6 for one end warp 3B in the weft direction of the remaining warp groups. As described above, the knitting of the warp yarns 3A and 3B is stopped for every predetermined number of weaving of the single net 5 to form a loop, and the knitting of the single net 5 is performed. It will continue.

The warp yarns 3B, 3B for hooking and weaving the hook members 3B, 3B to the net weaving yarns 3A, 3A are, for example, about 7 meshes of the single net 5, and the hooking connection is stopped. The warp yarns 3B, 3B, which are, for example, about three meshes of the single net 5 and are stitch-connected by the first weft yarn 4A in a portion where the hook connection is stopped, while being separated from the single net 5. Will exist in a belt shape.

Then, the warp yarns 3A, 3A and the warp yarns 3A
Single net 5 between hooks B and 3B not connected
In the continuous weaving, the second weft 4B for weaving the locking member in each warp group is entangled with the warp 3B.
And the end warp 3B of the warp group adjacent to one side in the weft direction
And a loop is formed on the back surface of the single net 5 by the jump-connected second weft 4B and the net 5. Of the wefts 4B forming the loop, The net 5 is used as the locking member 6 at the separated weft portion. By repeating the above weaving, the mesh size is 15 mm × 15 mm.
The vegetation net 1 in which the locking members 6 are formed on the back surface of the single net 5 at appropriate intervals in the warp direction is manufactured.

In this embodiment, the weft yarn 4B for forming the locking member 6 is jumped over the specified adjacent warp yarns 3A for the net weaving at a pitch of a half mesh of the single net 5. Although they are connected, for example, one of the single nets 5 may be sparser than this pitch.
The jump connection may be made at the eye-catching pitch or the two-eye pitch.

At the time of jump connection of the weft 4B, as shown in FIG. 6, the weft 4B is entangled with the warp 3A for net weaving so as to form a loop to form a tight structure. Although it is preferable that the net 1 is effectively prevented from being twitched, as shown in FIG.
May be inserted and locked only once, so as to be entangled with the warp 3A for net weaving. In this case, the vegetation net 1 can be made flexible since a loose structure can be formed. .

At the time of greening the slope N, as shown in FIG.
Vegetation that is stretched toward the side using anchors 8 or pegs 9 and that is mixed with plant seeds, such as fertilizers, soil conditioners, and water retention agents, which are necessary directly or indirectly for plant growth. The base material 2 is made into, for example, a gel form and sprayed by a suitable spraying machine so as to cover the vegetation net 1. At this time, the locking member 6 which is loosely separated from the single net 5 is loosened. However, it is locked on the gravels exposed on the slope N,
Since the function of preventing the displacement of the vegetation net 1 is exhibited, the slip of the vegetation net 1 against the slope N can be firmly achieved even if the number of the anchors 8 and the pegs 9 for extending the net is reduced. You.

Further, even if a gap is formed between the vegetation base material 2 and the slope N and the slope of the slope surface flows,
Since this is hooked on the locking member 6 and entangled, the erosion of the topsoil is effectively prevented, and the vegetation base material 2 is effectively spilled by entangled with the locking member 6. Is prevented.

The locking member 6 formed by the weft 4B is not limited to being formed on the back surface of the single net 5, but as shown in FIG.
A greening method may be adopted in which the vegetation base material 2 mixed with plant seeds is sprayed and formed using the anchors 8 and the pegs 9 and the vegetation base material 2 is sprayed.

In such a construction method, the vegetation base material 2 sprayed on the vegetation net 1 is entangled with the locking member 6 on the net,
Since the vegetation base material 2 is three-dimensionally held by the locking member 6 and the net 5, cracks are generated by drying in the vegetation base layer on the upper side of the net, and the vegetation base material 2 is caused by strong rainfall or the like. Is prevented from being washed away.

As shown in FIG. 10, when the locking members 6 are formed on both sides of the single net 5, the vegetation net 1 is firmly prevented from slipping on the slope N, and the slope of the vegetation top soil and the sprayed vegetation base material are provided. Needless to say, the spill prevention of No. 2 is effectively achieved.

In the vegetation net 1 shown in FIG. 10, the locking members 6 are alternately formed on both sides of the net 5 at predetermined intervals in the warp direction of the net 5. May be formed at the same position on both sides of the net.

Although not shown, a sheet supporting vegetation seeds is provided on the back side of the vegetation net 1 in the above-described three forms, and this is used as a vegetation base. By stretching the sheet on the slope with an anchor or a peg with the sheet facing the slope, and spraying the vegetation base material with, for example, a gel-like vegetation base material,
Greening of the slope can be effectively achieved.

At this time, on the side of the vegetation net 1 where the sheet is attached,
When the locking member 6 is formed by a loop, even if the sheet is peeled off from the vegetation net 1 after construction, the locking member 6 is locked so as to ride on the sheet so that the position of the sheet is reduced. Deviation will be prevented.

The sheet provided on the vegetation net 1 does not hinder the germination and growth of plant seeds.
Various water-soluble or water-decomposable materials such as crepe paper, polymer-based film or starch-based film, water-soluble paper with cold gauze, soft cotton, soft woven non-woven fabric, pulp-based non-woven fabric can be selected. , A sheet of thin cotton wrap by swoof, this sheet, plant seeds,
A vegetation base comprising a fertilizer, a soil conditioner and the like is adhered and held by a water-soluble sizing agent such as polyvinyl alcohol (PVA), and the sheet is water-soluble sizing agent similar to the above-mentioned water-soluble sizing agent. Is to be attached to the back side of the vegetation net 1.

Instead of the above-mentioned greening method, FIG. 11 and FIG.
As shown in FIG. 2 from the back surface side, the backing portion of the single net 5 is provided with a locking member 6 and a bag storage portion 10 alternately at appropriate intervals in the warp direction of the single net 5, so that the vegetation net is provided. The vegetation base 12 for greening is formed by storing a vegetation material storage bag 11 in the bag storage portion 10 of the vegetation base material 1 and the vegetation base 12 as shown in FIG. The greening of the slope N can also be effectively achieved by stretching the slope N with the nail 9 and spraying the vegetation base material 2 in a gel state on the vegetation base 12, for example.

An example of a procedure for manufacturing the vegetation net 1 used in this method will be described with reference to FIGS. 13 and 14. As in the above-described embodiment, the warp 3 for net weaving is used.
As, for example, 200 to 2000 made of polyethylene.
A monofilament of about denier is used, and the weft 4 is made of, for example, 300 to 30 made of polyethylene.
The vegetation net 1 is knitted by a Raschel loom as follows using a tape-shaped flat yarn of about 00 denier.

That is, the size of the mesh is 15 mm × 15 m
m, weaving a vegetation net 1 having a width of about 100 cm in the weft direction. First, a chain yarn obtained by chain-knitting several monofilaments is used as a warp 3 for net knitting, and 65 of these yarns are spaced at 15 mm intervals. Then, the weft 4 for net weaving made of flat yarn is sequentially entangled with this,
The single net 5 is knitted and woven (not shown, but the net woven in this way is the single net 5 shown in FIG. 4) with a size of × 15 mm.

At the time of weaving the single net 5, two warp yarns 3A, 3A for one net at the end are used.
From now on, two net knitting warp yarns 3A, 3A for each meshing unit are specified every six meshes, and the warp yarns 3A, 3A are formed with the net knitting yarns so as to form a warp group therewith. Is hooked and connected with another warp yarn 3B, 3B for weaving the bag storage unit made of, for example, a monofilament, and for the warp yarns 3B, 3B of each warp group, these are first weft yarns 4A for weaving the bag storage unit made of, for example, flat yarn. To form a stitch.

On the other hand, except for the warp group on one end side, a second weft thread 4B for weaving in a bag storage section made of, for example, a flat yarn is shown in FIG. As described above, the knitting of the warp yarns 3A and 3B is stopped for every predetermined number of weaving of the single net 5 to form a loop, and the knitting of the single net 5 is performed. It will continue.

The form of the net weaving up to now is not different from the weaving of the single net 5 shown in FIGS. 3 to 5, and the warp yarn for weaving the locking member as shown in FIGS. Are simply referred to as weft yarns 3B, 4A, and 4B for weaving the bag storage unit. As will be described later, the weft yarns 3B, 4A, and 4B for weaving the bag storage unit are formed by In addition, the locking member 6 is also knitted.

The warp yarns 3B, 3B for weaving the bag storage unit are hooked and connected to the above-described warp yarns 3A, 3A for net weaving, for example, about 25 meshes of the single net 5, and the hooking connection is stopped. The warp yarns 3B, 3B connected in a stitch-like manner by the first weft yarn 4A in a state where the single net 5 is, for example, about 6 meshes and the hooking connection is stopped, while being separated from the single net 5. Will exist in a belt shape.

The warp yarns 3A, 3A and 3
Single net 5 between hooks B and 3B not connected
In the continuous weaving of the warp group, the second weft yarn 4B for weaving the bag storage unit in each warp group is wrapped with the warp yarn 3B
And the end warp 3B of the warp group adjacent to one side in the weft direction
And jump connection repeatedly, and warp 3
Warp yarns 3A, 3A are formed by a first weft yarn 4A in which B and 3B are connected in a mesh shape, a second weft yarn 4B in which jump connection is repeatedly performed, and a single net portion 5A opposed to these.
The bag storage part 10 which is continuous in the weft direction is formed at the non-connection part between the and the warp yarns 3B, 3B. By repeating the above-described knitting, the back surface of the single net 5 having a mesh size of 15 mm × 15 mm. The vegetation net 1 in which the bag storage portions 10 are formed at appropriate intervals in the warp direction on the side is manufactured.

Further, the above further single net 5
After the continuous weaving, that is, after forming the above-mentioned bag storage portion 10, while knitting and weaving the single net 5 with a predetermined number of meshes, the second weft 4B for weaving the above-mentioned bag storage portion is The warp 3B, which has been entangled up to that point, and the end warp 3B of the warp group adjacent to one side in the weft direction are repeatedly jump-connected so as to be loosened, and the jump-connected weft 4B and net 5 form a single connection. A loop is formed on the back side of the net 5 of the net 5. Of the wefts 4B forming the loop, the weft portion that is separated from the net 5 is used as the locking member 6, and the above-described knitting is repeated. On the back side of the single net 5 having a mesh size of 15 mm × 15 mm, at an appropriate interval in the warp direction,
Thus, the vegetation net 1 in which the locking member 6 is formed is manufactured.

By storing the vegetation material storage bag 11 in the bag storage portion 10 of the vegetation net 1 having the above structure,
The vegetation base 12 for greening is formed, but in the vegetation base 12 having such a configuration, the vegetation net 1 is almost constituted by the single net 5, so that the entire net has a double structure. As compared with the above-described means, the manufacturing cost of the vegetation net 1 can be reduced, and the engagement member 6 and the bag storage section 10 can be formed only by appropriately jump-connecting the second weft 4B for weaving the bag storage section. Since it is formed, the vegetation net 1 including the locking member 6 and the bag storage portion 10 can be easily and inexpensively manufactured.
The storage of the vegetation material storage bag 11 is easy, and the storage bag 11 is securely held.

The vegetation material storage bag 11 provided on the vegetation base 12 is provided with a vegetation material 13 such as a fertilizer, a soil conditioner, and a water retention agent, which is necessary directly or indirectly for the growth of the plant. Nonwoven fabrics such as vinylon, such as polyvinyl alcohol, polyester, such as polyester, polyamide, such as nylon, and polyacrylonitrile, such as acrylic, etc. Nonwoven fabric, pulp nonwoven fabric, soluble paper, biodegradable plastic film and other corrosive materials and stored in a bag 14,
Plant seeds are mixed into the vegetation material 13 as necessary.

At the time of greening the slope N, as shown in FIG. 15, the vegetation base 1 in which the vegetation material storage bag 11 is stored in the bag storage section 10 of the vegetation net 1 in advance in a factory or a construction site.
The vegetation base material 2 mixed with plant seeds is turned into a gel, for example, with the locking member 6 of the vegetation base 2 facing the side of the slope N using an anchor 8 or a peg 9. The vegetation net 1 is sprayed so as to cover the vegetation net 1 with an appropriate spraying machine. On the back surface of the vegetation net 1, a locking member 6 that is loose and loose from the single net 5 is formed. Therefore, as shown in FIG.
Exhibits the function of preventing the displacement of the vegetation net 1, so that even when the number of the anchors 8 and the pegs 9 for extending the net is reduced, the slip of the vegetation net 1 on the slope N is firmly prevented. Achieved.

Further, since the sprayed vegetation base material 2 and the sloped surface soil are caught by the locking member 6 and become entangled with the vegetation base material 2 or the sloped surface soil, the loss of the vegetation base material 2 and the sloped soil is also effectively prevented.

In the state where the vegetation base 12 is stretched on the slope N, the weft yarn 4B jump-connected to the warp yarn 3B for weaving the bag storage part is separated from the other yarns.
In addition to the weft 4B freely adjusting to the unevenness of the slope N, the bag storage unit 10 formed by the weft 4B also adapts well to the slope N, and as a result, the vegetation material storage stored in the bag storage 10 Since the bag 11 is in close contact with the uneven surface of the slope N, the vegetation material storage bag 11 not only supplies a predetermined fertilizer nutrient, but also exerts a damming effect to reduce the erosion of the topsoil of the slope N. It will surely prevent it.

Although not shown, when the slope N is greened by spraying the vegetation base material 2, a storage bag 11 containing the vegetation material 10 and a vegetation material having a different configuration from the vegetation material storage bag 11 are used. A storage bag, that is, a polymer film or starch film which does not hinder the germination and growth of vegetation and which dissolves with water, or a water-soluble paper with a cold gauze, such as Bonric (trade name, manufactured by Venus Seishi Paper Co., Ltd.) A vegetation material storage bag in which, for example, grass seeds are stored in a bag made of a soluble material is, for example, alternately stored in the bag storage portion 10 of the vegetation net 1, and this is used as a vegetation substrate 12 for greening. Alternatively, the vegetation base material 2 may be sprayed on the slope N.

In the above embodiment, the locking member 6 and the bag storage portion 10 are alternately provided on the back surface of the single net 5 at appropriate intervals in the warp direction of the single net 5. Although the vegetation material storage bag 11 is stored in the one bag storage unit 10 and the locking member 6 is stretched toward the slope N side,
The vegetation base 12 may be replaced with a greening method in which the vegetation base 12 is turned upside down on the slope N.

Alternatively, the vegetation substrate 12 is turned upside down.
This is the same as the greening method in which the bag storage portion 10 is stretched on the slope N. However, as shown in FIG. A vegetation base in which a locking member 6 is formed on the surface of the net 5 using a weft different from the weft 4B for weaving, and a vegetation material storage bag 11 is stored in the bag storage section 10 of the vegetation net 1. 1
The greening method may be adopted in which the vegetation base material 2 is stretched with its locking member 6 facing the front side, and the vegetation base material 2 is sprayed so as to cover the vegetation base material 12.

When such a greening method is adopted, the vegetation base material 2 sprayed with the vegetation net 1 is entangled with the locking member 6, and the vegetation base material 2 is three-dimensionally formed by the locking member 6 and the net 5. This prevents the vegetation base material layer on the upper side of the net from cracking due to drying, and prevents the vegetation base material 2 from flowing off due to strong rainfall or the like.

As shown in FIG. 17, the locking members 6 are formed on both sides of the single net 5 and are used as the vegetation net 1, and the storage bag 10 for the vegetation material is stored in the bag storage section 10. The vegetation base 12 may be constructed by using the greening method in which the vegetation base 12 is stretched on the slope N and the vegetation base material 2 is sprayed. Needless to say, the prevention of slippage and the prevention of runoff of the slope surface soil and the sprayed vegetation base material 2 are effectively achieved.

In the vegetation net 1 shown in FIG. 17, the locking members 6 and 6 are formed at the same position on both sides of the net, and the locking members 6 are arranged at predetermined intervals in the warp direction of the net 5. May be alternately formed.

In the above-described net knitting, the connection of the warps 3A and 3B is stopped with a small number of meshes, such as every single mesh or every two meshes of the single net 5, and the weft yarn 4B for weaving the bag storage section is formed. When the jump connection is made across the end warps 3B, the bag storage portion 10 can be formed almost continuously in the warp direction of the vegetation net 1.

However, when the bag storage section 10 is formed continuously as described above, the locking member 6 is connected to the bag storage sections 10 and 10.
In this case, the locking member 6 cannot be formed, but in this case, the greening method shown in FIG.
A greening method in which a locking member 6 is formed on the surface side of the single net 5 and the vegetation substrate 12 using the vegetation net 1 is placed on the slope N with the locking member 6 facing the surface side. It is good to take it.

In the embodiment shown in FIGS. 11 to 14, the locking member 6 and the weft 4 forming the bag storage portion 10 are used.
B, warp yarns 3B, 3B adjacent to each other
In this case, the jump connection is performed at a half-mesh pitch of the single net 5, but the jump connection is performed at a single-mesh pitch or a double-mesh pitch of the single net 5 so as to be sparser than this pitch. It may be.

Although the number of the warp yarns 3B forming the bag storage section 10 is set to two, as shown in FIG.
B may be three and these may be connected in a mesh by the first weft 4A, or the warp 3B may be four or more, or as shown in FIG. 19, the warp 3B may be one. It is good. In these drawings, the illustration of the locking member 6 by the jump connection of the second weft 4B is omitted.

The second weft 4B to be jump-connected to form the locking member 6 and the bag storage portion 10 is entangled only with one end warp 3B at one end in the weft direction in the warp group.
