[Patent Document 1]
Japanese Patent Laid-Open No. 2002-21087
As the first conventional technique, there is a mesh body composed of a wire mesh.
[0005]
In addition, as a second conventional technique, there is one disclosed in Patent Document 1, and according to this, the mesh body is configured by knitting a vertical string and a horizontal string formed of water-retaining fibers. Yes.
[0006]
In forming the slope using the mesh body in the first and second conventional techniques, first, the mesh body is laid on the slope on which the slope is to be formed, and the customer's soil faces the mesh body. Spray with seeds. Then, the soil is held at the spraying position by the mesh body, and a slope having a predetermined shape is formed. Thereafter, the germination and growth of the seeds are promoted by this soil and the water absorbed by the soil, so that the slope is maintained in a predetermined shape for a long time by the plant growing on the slope. The
[0007]
In particular, according to the second conventional technique, since the net body has water retention fibers, seed germination and growth are caused by water absorbed and retained by the fibers in rainy weather or the like. It is supposed to be promoted more.
[0008]
[Problems to be solved by the invention]
By the way, the net body made of wire mesh in the first prior art has sufficient strength to hold the soil in that position, but lacks water retention and tends to dry out. There is a risk that the germination and growth of seeds in the soil will be insufficient.
[0009]
Further, according to the second conventional technique, the water retention of the net body can more surely give the plant overgrowth on the slope, but the strength for holding the soil in that position tends to be insufficient. It is.
[0010]
Therefore, it is conceivable to combine the networks of the first and second prior arts to mutually complement each other's actions. However, in this way, in addition to the existence of both networks, Thus, the configuration becomes extremely complicated, for example, a separate coupling member is required for coupling these two mesh bodies, and the molding operation of the target mesh body becomes extremely complicated due to the coupling operation of the both mesh bodies. The problem arises.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0019]
In FIG. 2, reference numeral 1 denotes a slope on a mountain or bank, and a slope-forming net 2 is provided which makes it possible to form the slope 1 into a predetermined shape and to hold the predetermined shape for a long time. ing.
[0020]
1 and 3, the mesh body 2 includes a wire mesh 3 as a main body thereof, and a cable body 4 knitted into the wire mesh 3 and connected to the wire mesh 3. While traversing substantially the center of each mesh 5 of the wire mesh 3, both ends of each mesh 5 are connected to the wire mesh 3.
[0021]
The wire mesh 3 is a rhombus wire mesh, and includes a plurality of wire members 8 that extend while being bent in a zigzag shape toward one direction X and are arranged in parallel to each other in a direction Y orthogonal to the one direction X. The material 8 includes a linear portion 9 linearly extending in a direction inclined with respect to the one direction X and a bent portion 10 formed at the extending end of the linear portion 9 integrally and repeatedly. The wire portions 8 and 8 adjacent to each other in the orthogonal direction Y are engaged with each other in an intersecting manner, and the pitches of the bent portions 10 have the same dimensions and the wire materials. 8 and 8 have the same shape and size.
[0022]
The strip 4 is a string-like body, extends linearly in the one direction X, and a plurality of the strips 4 are arranged in parallel in the orthogonal direction Y. These strips 4 are separated from each other. .
[0023]
The cords 4 extend linearly in the one direction X through the bent portions 10 and 10 engaged with each other as described above, and the cords between the bent portions 10 and 10 are connected. Each part of the strip 4 is sandwiched between the two bent portions 10 and 10, and is firmly connected to the mesh body 2 in a state of being compressed and contracted by the sandwiching.
[0024]
In particular, in FIGS. 4 and 5, the wire members 8 adjacent in the orthogonal direction Y are separated from each other, and the wire member 8 and the cable body 4 are orthogonal to each other as shown in FIGS. It is possible to move relative to each other in the direction Y. By the relative movement in which the wire material 8 and the wire body 4 approach each other, the pinching of the wire body 4 by the bent portions 10 and 10 is automatically released, and the wire material 8 and the wire material are connected to each other. The strips 4 are stacked together to form a compact shape.
[0025]
Each of the wire members 8 is bent so as to draw a spiral in the same turning direction toward the one direction X. Therefore, as shown in FIGS. 4 and 5, the wire members 8 approach each other. When viewed relative to each other, the space 12 is formed between the two bent portions 10 and 10 when viewed from the line of sight along the one direction X (FIG. 5). It will be arranged in a straight line.
[0026]
In all the drawings, the above-mentioned cord body 4 is a string-like body in the illustrated example, and the material thereof is formed of water-retaining fibers. More specifically, the above-mentioned ridge body 4 is formed from a fiber made of a polymer mainly composed of polyacrylic acid sodium salt, and its water absorption performance is about 80 times its own weight, such as high water absorption and Has been. The above-mentioned cord body 4 is in an unabsorbed state and has sufficient strength (100 to 150 N / Yarn), but after sufficient water absorption, it loses strength and decomposes.
[0027]
When forming the mesh body 2, each wire material 8 is sequentially formed endlessly from one end side in the orthogonal direction Y of the wire mesh 3 by an ordinary wire mesh forming machine. As shown in FIGS. 4 and 5, the incoming wire materials 8, 8 are relatively moved so as to approach each other in the orthogonal direction Y, and the spaces 12 are arranged in one direction X. ing. Therefore, the strips 4 are inserted into the spaces 12 by a shuttle mechanism or the like, and the spaces 12 and the strips 4 are formed into a compact shape with a stacked structure in which they are stacked.
[0028]
2 and 3, when the slope 1 is formed into a desired shape using the mesh body 2, first, each cord body of the mesh body 2 with respect to the slope 14 on which the slope 1 is to be formed. The mesh body 2 is stretched so that the wire 4 and the wire material 8 extend in the horizontal direction, and the mesh body 2 is fixed to the slope 14 with a pile.
[0029]
In the above case, since the mesh body 2 has a compact shape with the above-described stacked structure, as a first construction method, first, an upper end portion that is one end portion in the orthogonal direction Y of the mesh body 2 above the inclined surface 14. Then, the mesh body 2 is lowered along the slope 14 with a crane or the like to expand the mesh body 2 to have an original shape as shown in FIG. Then, the net 2 can be stretched around the slope 14. As a second construction method, first, a lower end, which is one end in the orthogonal direction Y, of the mesh body 2 is fixed to the lower side of the slope 14 with a pile, and then the mesh body 2 is fixed to the slope with a crane or the like. 14, the net body 2 is developed by being raised along the line 14 to have an original shape as shown in FIG. Then, the net 2 can be stretched around the slope 14. When the mesh body 2 is stretched, in the compact mesh body 2, the wire members 8, 8 adjacent to each other in the orthogonal direction Y are relatively separated from each other with the development, and each of the bent portions 10. , 10, the cord body 4 is sandwiched between them, and the cord body 4 is connected to the net body 2.
[0030]
Next, the customer soil 16 is sprayed together with the seeds from the outside to the net 2 stretched as described above. Then, the customer's soil 16 is held at the spraying position by the wire mesh 3 and the cable body 4 of the mesh body 2, and the slope 1 having a predetermined shape is formed. Thereafter, germination and growth of the seeds and natural seeds are promoted by the soil 16 and the water that has been absorbed and retained by the soil 16 and the striated body 4, so that the slope is 1 is held in a predetermined shape over a long period of time by a plant growing on the slope 1. When the above-mentioned cable body 4 absorbs enough water, it is decomposed and becomes part of the soil on the slope 1 and exhibits a water retention function thereafter, and the occurrence of new pollution is prevented.
[0031]
According to the above configuration, the mesh body 2 includes the wire mesh 3 and the cord body 4 knitted into the wire mesh 3.
[0032]
For this reason, in the case where the slope 1 is formed and the mesh body 2 is laid on the slope 14 such as a mountain and the customer soil 16 is sprayed on the mesh body 2, the wire mesh 3 and the ropes in the mesh body 2. In cooperation with the body 4, the soil 16 is held in the spray position, so that the slope 1 is held in a predetermined shape over a long period of time.
[0033]
The mesh body 2 is obtained by weaving the wire body 4 into the wire mesh 3, and does not require a separate connecting member for joining the wire body 4 to the wire mesh 3. The structure of the body 2 can be simplified and the net body 2 can be easily formed.
[0034]
The cable body 4 crosses substantially the center of each mesh 5 of the wire mesh 3, and both ends of each mesh 5 are connected to the wire mesh 3.
[0035]
For this reason, according to the rope body 4 in which both ends are connected to the wire mesh 3 as described above, compared to the case where the wire body 4 is connected to the wire mesh 3 by simply sewing each mesh 5, The customer soil 16 that has entered each of the meshes 5 can be more reliably held at the spray position, and thus the slope 1 is held in a predetermined shape for a longer period of time.
[0036]
Further, as described above, the wire mesh 3 has a plurality of wire members 8 extending while being bent in a zigzag shape toward one direction X and arranged in parallel to each other in a direction Y orthogonal to the one direction X. In the slope forming net body in which the bent portions 10, 10 of the two wire members 8, 8 adjacent to each other in the direction Y are engaged with each other to form the wire mesh 3, the bent portions 10, 10 engaged with each other. The striated body 4 extends between the two.
[0037]
Here, as described above, when the strip body 4 extends between the bent portions 10 and 10 engaged with each other as described above, the strip body 4 is substantially at the center of each mesh 5 of the wire mesh 3. The both ends of each mesh 5 are sandwiched between the bent portions 10 and 10 and connected to the wire mesh 3.
[0038]
For this reason, according to the striated body 4 of the mesh body 2, the customer soil 16 that has entered each mesh 5 can be more reliably held at the spraying position. It is held in a predetermined shape for a long time.
[0039]
And since the above-mentioned cable body 4 was connected to this wire net 3 effectively using the original shape which the above-mentioned wire net 3 has, the structure of the above-mentioned net body 2 becomes simpler.
[0040]
In addition, as described above, the plurality of wire members 8 and 8 are separated from each other, and the wire members 8 and 8 and the cable body 4 can be moved relative to each other in the orthogonal direction Y.
[0041]
For this reason, if the two wire materials 8 and 8 adjacent in the orthogonal direction Y are relatively moved so as to approach each other, the space 12 is formed between the bent portions 10 and 10 of the both wire materials 8 and 8. In the case where the cord body 4 is knitted into the wire mesh 3, the cord body 4 is simply inserted into the space 12, and then the two wire members 8, 8 are relatively moved so as to be separated from each other. What is necessary is just to make the said rope body 4 clamped between the bending parts 10 and 10 of both the wire materials 8 and 8. FIG. Therefore, the braiding 4 can be easily knitted into the wire net 3, that is, the net 2 can be easily formed.
[0042]
Further, if the wire members 8 and the ridges 4 are moved relative to each other in the orthogonal direction Y, the mesh body 2 can be made into a compact shape. The work at the time of tensioning can be facilitated, that is, the slope 1 can be easily formed.
[0043]
Further, the strips 4 and 4 adjacent in the orthogonal direction Y are separated from each other.
[0044]
For this reason, when the wire body 8 and the striated body 4 are moved relative to each other in the orthogonal direction Y, such as when the mesh body 2 is deployed, the adjacent striated bodies 4, 4 interfere with each other. This prevents the mesh body 2 from being unfolded easily, so that the slope 1 can be easily formed.
[0045]
Further, as described above, the above-mentioned cord body 4 is water retaining.
[0046]
For this reason, when the slope 1 is formed by the mesh body 2, germination and growth of seeds are promoted by the water retained in the rope body 4, so that the slope 1 becomes the slope 1. It is held in a predetermined shape for a long time by the growing plant.
[0047]
Although the above is based on the illustrated example, the ends of the wire material 8 of the wire mesh 3 may be coupled to each other so that the wire material 8 cannot be moved relative to each other. Moreover, the above-mentioned cable body 4 may be made of a material that remains permanently without being decomposed by water retention after the slope 1 is formed, and may be provided with a reinforcing material. Further, the rope body 4 may be a rope or a belt. The cord body 4 is not necessarily provided between the adjacent wire members 8, 8, and may be provided for each of the plurality of wire members 8. Further, each of the striated bodies 4 may be integrally formed by bending a single striated body. Moreover, the said net | network body 2 may be stretched | stretched so that each said wire material 8 and the cable body 4 may extend in the inclination direction of the slope 14, and the wire material 8 and the cable body 4 may be orthogonally crossed.
[0048]

Both ends of each mesh are sandwiched between the two bent portions and connected to the wire mesh.
[0055]
For this reason, according to the striated body of the mesh body, it is possible to more reliably hold the soil that has entered each mesh at the spray position, and thus the slope is in a predetermined shape for a longer period of time. Retained.
[0056]
And since the above-mentioned cable body was connected to this wire mesh effectively using the original shape which the wire mesh had, the composition of the above-mentioned mesh body becomes simpler.
[0057]
Further , the above-mentioned cord body has water retention and high water absorption .
[0058]
For this reason, when the slope is formed by the mesh body, the water that has been retained in the striatum promotes the germination and growth of the seeds, so that the slope is planted by this plant. It is held in a predetermined shape for a long time.
[0059]
According to a second aspect of the present invention, the plurality of wire materials are separated from each other, and the wire material and the cable body can be moved relative to each other in the orthogonal direction Y.
[0060]
For this reason, if the two wire materials adjacent in the orthogonal direction are relatively moved so as to approach each other, a space is formed between both bent portions of these wire materials. Simply insert the cord body into the space, and then move the two wire materials relative to each other so that they are sandwiched between the bent portions of the two wire materials. Good. Therefore, the braid can be easily knitted into the wire net, that is, the net can be easily formed.
[0061]
In addition, if the wire members and the cable body are moved relative to each other so as to approach each other in the orthogonal direction, the mesh body can be made into a compact shape. Can be easily achieved, that is, the slope can be easily formed.
