DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetation bag and a vegetation net used for vegetation for slope protection.

[0002]

2. Description of the Related Art Bare lands and slopes in newly constructed lands, etc., are extremely concerned with environmental protection and security because problems such as the outflow (runoff) of earth and sand will occur unless vegetation is actively protected. Is leaning. Various methods have been proposed and implemented as a method for vegetation such as bare ground and slopes. This vegetation method is roughly divided into a method of directly spraying plant seeds with fertilizer and the like on bare ground and slopes, and forming a frame on bare ground and slopes to prevent the outflow of sediment. Such a method is a method of sowing seeds, and a method of attaching a vegetation material bag containing fertilizers or the like to a net and covering the slope with the net as shown in FIG.

[0003] Above all, the vegetation method using a net as shown in Fig. 9 is very easy to construct.
In recent years, it has been particularly frequently used. For example,
JP-B-57-55851, JP-B-57-5585
No. 2, JP-B-59-37369 discloses such an example. That is, Japanese Patent Publication No. 57-558
No. 52 discloses "a vegetation net formed by providing a storage portion for vegetation material in the net," and Japanese Patent Publication No. Sho.
Japanese Patent Application Laid-Open No. 9-37369 describes "a water-vulnerable sheet bag body in which a housing is provided at an appropriate interval of a mesh body and a vegetative base material is filled in a bag body formed of a water-vulnerable sheet, and an insoluble sheet. A vegetation base for a difficult-to-vegetable area, in which an insoluble sheet bag body filled with a vegetation base material in a bag body is arranged and accommodated in the accommodation portion of the mesh-like body, is shown.

[0004] In each of the inventions exemplified above, it is necessary to form a storage section for vegetation material. According to the description of each of the above publications, the configuration of the storage section is described as follows. It is a method of making a part that is not woven or fused by about 5 cm at intervals of 30 to 50 cm, and the part that is not woven or fused is used as a storage part for vegetation material. ” This is a method in which two nets are stacked to form a part that is not woven or fused by about 15 cm every 4 to 40 cm, and the part that is not woven or the part that is not fused is formed as a cylindrical bag housing part. According to another manufacturing method and shape, a single net-like body is pinched by about 30 cm at intervals of 4 to 40 cm, and the knob portion is knitted, or a rope is passed or fused to form a housing portion. There is also a method and a form in which two nets are superimposed, two nets are knitted with a rope at an appropriate interval, and a space is provided between the two nets. ."That's what it means.

By the way, according to the descriptions in the above publications, in order to form the storage portion for the vegetation material, it is necessary to mainly form two reticulated bodies in layers, and the reticulated bodies are accordingly reduced. It requires a lot of material to form. In the first place, since this mesh is mainly for holding the bag containing the vegetation material at a predetermined position on the slope, there is no need to increase the strength more than necessary, and especially in the lateral direction of the slope. However, strength is not so required. Therefore, forming the storage portion for the vegetation material by stacking two nets not only requires a large amount of material, but also has an unnecessarily high strength, which is an excessive quality. .

Further, in the above-mentioned conventional example, the storage portion of the vegetation material is formed by "making a portion which is not woven or fused about 5 cm every 30 cm to 50 cm, or about 15 cm every 4 to 40 cm". Although it is so-called fixedly formed, according to the drawings and the like in the above publications, it seems that all the bags containing the vegetation material are inserted into the storage portion. By the way, the slope on which the main vegetation net is placed is not only a uniform slope depending on the place, but also the quality of the soil constituting it is not uniform,
When arranging a bag containing vegetation material on a slope using this vegetation net, it is necessary to adapt the situation to the situation of the slope. However, if the storage portion is fixedly formed in the mesh, it is naturally difficult to perform vegetation according to the situation of the slope, and in some cases, a plurality of types of meshes, that is, It is necessary to prepare meshes having different intervals.

Further, since the vegetation material flows on the slope due to rain or the like, even if the slope is uniformly inclined, it is necessary to keep more vegetation material in the upper part of the slope to improve the vegetation efficiency. It is more advantageous. However, if the storage portions of the mesh body are fixedly formed at equal intervals as described above, such a measure cannot be taken.

[0008] Therefore, the applicant has filed Japanese Patent Publication No. Hei 4-2252.
As proposed in Japanese Patent Publication No. 4 (1999) -1994, "by knitting a plurality of yarns, a vegetation mesh formed of a warp portion located in the longitudinal direction of the slope and a weft portion connecting these warp portions. A knitting portion is formed by knitting all of the warp yarn portions into one or two of the weft yarn portions adjacent to each other, and the next two to four weft yarn portions located next to about half of the connection portion are formed. Divided into front and back by the amount of, the bag-shaped portion is formed by alternately knitting each warp portion in each of these weft portions in the horizontal direction, and the bag-shaped portion and the connection portion in the vertical direction Vegetation netting characterized by being formed in large numbers continuously, so as not to be excessive quality,
A vegetation mesh body which can surely hold a vegetation bag for vegetation with a minimum amount of material and can arrange the vegetation bag in accordance with the situation of a slope has been completed.

However, the subsequent studies by the inventors have found that the actual slope vegetation is in a very complicated situation, and it is necessary to make further improvements. That is, as shown in FIG. 8, the slope is rarely in a completely flat state, and the vegetation net may be partially lifted, and the vegetation bag supported by the vegetation net may be used. Is also raised. For this reason, even if the vegetation material bag absorbs moisture such as rain and soaks fertilizers etc. on the slope, fertilizers etc. will not flow out enough unless there is a moderate amount of rain. Can not do. In addition, when the vegetation material bag is in a state of being lifted from the slope, the drying is also performed early, and if the vegetation material bag contains seeds for vegetation, sufficient germination cannot be expected. Will be. In addition, if the vegetation material bag is lifted off the slope, the fertilizer that has flowed out has no support on the slope, so it will run off along with the earth and sand that has flowed down from above. is there.

Therefore, the present inventor has conducted various studies on how to ensure the vegetation using this kind of vegetation bag even if the slope has irregularities. Thus, the present invention has been completed.

[0011]

SUMMARY OF THE INVENTION The present invention has been made based on the above circumstances, and the problems to be solved are as follows.
This is a problem when the vegetation material bag or the vegetation mesh for supporting the vegetation material is raised on the slope.

[0012] Then, first, it is an object of the invention according to claim 1, even if they are supported in a floating state on the slope, the vegetation material bag as possible out to perform reliably and long term vegetation for slope Is provided by a simple configuration.

Another object of the present invention is to stably supply a vegetation base material for a long period of time even if the vegetation base material is arranged in a floating shape on the slope. Another object of the present invention is to provide a net for vegetation that can prevent runoff of earth and sand on a slope.

[0016]

The operation of the vegetation material bag 10 of the first embodiment and the vegetation net 20 of the second embodiment will be described in detail below, together with the mode of use.

Regarding the vegetation material bag 10 of the first aspect, as shown in FIGS.
The vegetation mesh (not necessarily the vegetation mesh 20 having the structure of claim 2) is accommodated and supported in the bag-like portion 21 of the vegetation mesh placed on the bag. It is formed as a long one arranged in the horizontal direction of the slope 40 by the shape part 21. In addition, this vegetation material bag 1
Reference numeral 0 denotes a state in which a vegetation base material 30 such as a fertilizer, a soil conditioner, and a water retention material is wrapped therein, and the lower half of the non- dissolved portion
1, and is obtained by forming into a bag in the upper about half the dissolve unit 12. Then, when the vegetation material bag 10 is attached thereto or a vegetation netting housed and held in a bag-like portion 21 as described later is disposed on the slope 40, as shown in FIGS. in its lower half a minute to a valley and non soluble <br/> solution unit 11, the upper about half the dissolve unit to be the crest side 12
And was it also to the.

Therefore, if rain or the like falls, the vegetation material bag 10
Dissolve unit 12, together with the vegetation base material 30 in the vegetation material bag 10 began its solubility is in a state capable of absorbing moisture, as shown in (b) of FIG. 4, a gradual or sufficient If it rains, it disappears early. In contrast, the non-dissolved part 11 of the vegetation material bag 10, since it is not to dissolve in rain or the like, For example according to claim 2 vegetation for meshwork 20
And remains in the bag-shaped portion 21 and is kept open toward the mountain side. For this reason,
A part of the vegetation base material 30 wrapped in the vegetation material bag 10
As shown in FIG. 4 (a), the non-dissolved portion 11 keeps being held.

That is, the melting part 12 is melted by rain or the like.
Then, the vegetation base material 30 wrapped in the vegetation material bag 10
Since the upper part has nothing to hold it, the slope 4
0, and if the vegetation material bag 10
Of the vegetation net 20 holding the surface rises from the slope 40.
Even if it is sprout, the spilled vegetation substrate 30
Fill the raised part to some extent to form a "weir"
This will create an opportunity. Of course, mesh for vegetation
If the body 20 is in contact with the slope 40,
The dropped vegetation base material 30 remains in the non-dissolved portion 11.
The opportunity to form a “weir” with the vegetation substrate 30
Indeed, it will be made.

In this case, if the vegetation net 20 holding the vegetation material bag 10 is lifted off the slope 40 as shown in FIGS. 4A and 4B. As described above, all of the vegetation base material 30 wrapped in the vegetation material bag 10 does not flow out, as described above. A "weir" is formed to hold the ground. Of course, it is rare that the raised portion of the vegetation net 20 is present over the entire length of the vegetation material bag 10, and rather, the vegetation net 20 is in contact with the slope 40 at any part of the vegetation net 20. Therefore, as shown in (b) of FIG.
Is accumulated more and more on the mountain side of the non-dissolving portion 11 constituting the above. During this time, the undissolved portion 11
Is for holding a part of the vegetation base material 30 wrapped in the vegetation material bag 10, whereby the slope 40
The vegetation activity of the is continuing. That is, the vegetation material bag 10 ensures that vegetation on the slope 40 is performed for a long period of time.

The vegetation material bag 10 is about half of the lower side.
Yes by the undissolved portion 11 and the upper about half the dissolve unit 12, because that is the one that may be formed as elongated bag condition, for example, the width enough to surround the entire circumference of the vegetation material bag 10 A non-dissolving portion 11 having a width about half that of the melting portion 12 is integrated with a lower portion of either the inside or the outside of the melting portion 12.
It can be formed by closing both edges, and the manufacture thereof can be easily performed.

[0022] - The vegetation for meshwork 2 0 Vegetation for meshwork 20 of claim 2, the warp portion 22 positioned in the longitudinal direction of the slope 40, the weft thread portion 2 for connecting these warp 22
3 and the weft portion 23 is divided into front and back portions by about half the amount, and each of the weft portions 23 is provided with a respective one of the warp portions 2.
2 is alternately knitted in the lateral direction so that
1 since it is obtained by forming a, as shown in FIGS. 1 and 6 is the vegetation material bag, such as a vegetation material bag 10 according to the claim 1 can retract and to each bag-like portion 21. Therefore, as shown in FIG.
, The vegetation material bag such as the vegetation material bag 10 is held substantially horizontally with respect to the surface of the slope 40.

Each bag-like portion 2 of the vegetation net 20 is
The mesh of about half of the lower side, which is the valley side of each warp portion 22 or the weft portion 23 constituting the front and back sides of 1, is made finer than that of the upper half and the lower half of the bag-shaped portion 21 Since a part of the vegetation base material 30 accommodated in the bag-shaped portion 21 is held, the vegetation material bag is supposed to be made of a water-soluble material, and is completely formed by rain or the like. even it disappears, as shown in FIG. 7, a portion of the vegetation substrate 30 Ru Nodea which will remain pending. In other words, the mesh
About half of the lower side of the bag-shaped portion 21 thus formed is covered with the vegetation substrate 30.
Do not drop it on the slope 40 and keep it received.
Thus, the vegetation net 20 in claim 1 is constituted.
The same action as the undissolved portion 11 of the vegetation bag 10 will be performed.
Because What slave, the bag-like portion 21 of the vegetation for the mesh-like body 20 is not able to become abolished vegetation substrate 30 within a short period of time.

Further, since each bag-like portion 21 of the vegetation net 20 holds a part of the vegetation base material 30 for a long period of time as described above, the bag-like portion 21 flows on the slope 40 from above. A "weir" for retaining the sediment that came in is formed. Of course, this vegetation net 20
It is rare that the raised portion of the vegetation exists over the entire length thereof, and rather, the floating portion is in contact with the slope 40 at any portion of the vegetation net 20, so that the contact portion is the center of FIG. As shown in (b) of FIG.
Sediment will be stored more and more on the mountain side of the area. During this time, the lower part of the bag-shaped portion 21 retains a part of the vegetation base material 30, whereby the vegetation action of the slope 40 is continued. That is, the vegetation net 20 ensures that the vegetation on the slope 40 is performed for a long period of time.

The vegetation net 2 of the following embodiment is shown.
At 0, although the overall thickness of each weft portion 23 constituting the front and back portions of each bag-like portion 21 is half of the connecting portion 24, a lateral force is applied to the vegetation net 20. Since there is almost no occurrence, it has sufficient strength to maintain the interval between the warp yarn portions 22. Needless to say, each of the front and back portions of each bag-shaped portion 21 is a mesh-shaped bag that can be opened on the left and right due to the connection portions 24 located above and below it. In the vegetation net 20, each bag-like portion 21 is located in a large number while being connected by one or two adjacent connecting portions 24, so that each bag-like portion 21 is selected. If the vegetation material bag 10 is stored by using the vegetation material bag 10, it is possible to freely change the density of the vegetation material bag 10 with respect to the slope 40.
