た。2. Description of the Related Art Conventionally, the above-mentioned vegetation net structure has, for example, a structure shown in FIGS. That is, the conventional vegetation net structure shown in FIG. 7 has upper and lower ground textures 73 formed in a mesh shape having a size that does not inhibit grass growth by intersecting the vertical threads 71 and the horizontal threads 72.
74 is provided, the upper and lower ground textures 73 and 74 are joined by the single woven portion S, and the flat circular space portion 75 is formed between the upper and lower ground textures 73 and 74 by the double woven portion D. This net for vegetation The structure is laid on the slope, and soil (mixed soil) is mixed with the soil, fertilizer, seed bark (barley) or bark compost, grass roots, water, etc. in the space 75 described above. Although it is intended to protect the surface, a space portion 76 having a substantially triangular shape when seen from the side is formed between the slope to be protected and the vegetation net structure. There was a problem that the growth of grass roots became insufficient and it was not possible to protect the slope sufficiently. In addition, since the mixed soil inflow method is limited to the left and right lateral directions, there is a problem that the mixed soil is clogged in the middle of the circular space portion 75 and the mixed soil inflow work efficiency deteriorates. .

難な問題があった。On the other hand, in the conventional net structure for vegetation shown in FIG. 8, upper and lower ground textures 83 are formed in a mesh shape having a size that does not inhibit grass growth by intersecting vertical threads 81 and coco threads 82. , 84 are provided, and the single weave section S has upper and lower ground structures 8
3, 84 are joined together, and the double weave section D is used for the upper and lower ground structures 83, 8
A space portion 85 having a substantially semicircular shape is formed between the four, and the above-described vegetation net structure is formed so that the lower ground texture 84 formed in a planar shape (flat shape) is in contact with the slope. Although it is laid on the surface and mixed soil is poured into the above-mentioned space portion 85 to protect the slope, the above-mentioned substantially semicircular space portion 8 is provided.
A space 86 is formed between 5 and 85, which has a substantially inverted triangular shape when viewed from the side.
As a result, the grass stems and leaves in the mixed soil grow insufficiently in this space 86, and there is a problem that sufficient slope protection cannot be achieved. In addition, since the inflow direction of the mixed soil is limited to the lateral direction as in the conventional structure of FIG. 7, the mixed soil is clogged in the middle part of the semicircular space portion 85, and the inflow work of the mixed soil occurs. There was a problem that the efficiency deteriorated. Further, by appropriately processing the left and right ends of the conventional vegetation net structure shown in FIG. 8, it is possible to sequentially flow the mixed soil into the space 85 in a meandering manner. Since the inflow resistance gradually increases as the amount increases, there is a problem that it is difficult to smoothly flow the mixed soil into the entire vegetation net structure that has been engraved on the slope in a short time.

である。There is also a revetment mat structure in which upper and lower base fabrics made of nylon or polyester are connected to each other by ropes, and concrete or mortar is poured between the base fabrics to construct a revetment. Since the above-mentioned base cloth has no mesh structure, it cannot be used for vegetation.

Are arranged in the warp yarn directions of the ground textures 3 and 4, and the number of warp yarns 1 at the portion where the knotting means is oriented is increased to increase the warp yarn density at the portion. There is an effect that the binding strength of the means (see Twain 5) and the strength of the ground textures 3 and 4 themselves can be reinforced by the warp yarn 1. Further, as compared with the structure in which the above-mentioned connecting means is arranged in the weft direction, the flow resistance of the mixed soil C can be reduced.

In each of the previous embodiments shown in FIGS. 1 and 4, the length of the connecting portion 5a of the twine 5 is approximately a predetermined interval A. Although the lengths of the joints 5a in the twine 5 are set to be relatively short in the embodiment shown in FIG. 5, the ends of the joints 5a in the upper ground structure 3 and the lower ground are set. Top and bottom formed by arranging two interval holding parts 5b, 5b that connect the ends of the connecting part 5a in the tissue 4 so as to intersect in an X shape when viewed from the side and with a predetermined interval E therebetween. 5 in each organization 3 and 4
The number of the weft yarns 2 is increased only in the area where a is arranged, and the reinforcing portion 6 having a high weft yarn density is formed. Here, the connecting portion 5a of the above-mentioned Twain 5 has the upper and lower ground textures 3,
No. 4 yarn is entangled and the twine structure of the joint 5a prevents the twine 5 from being displaced. The above-mentioned predetermined interval L, so-called height, is set by a trigonometric function from the lengths of the interval holding parts 5b, 5b as floating weave parts. Even if configured in this way, the same operation and effect as those of the above-described respective embodiments can be obtained. Therefore, in FIG.
