  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

1 to 4, the size of the strip 1 is, for example, a width (length in the lateral direction) W of 0.2 m, a length (length in the longitudinal direction) L of 5.0 m, and a thickness a. Is 13 mm, and the internal space S formed between the upper and lower two sheet portions 2 and 3 is maintained by a hanging thread (sewing thread) 4. The band-like body 1 is one in which dry mortar (an example of a curing material) M that is cured by water absorption or moisture absorption is accommodated in the internal space S. The dry mortar M of this embodiment is a mixture of, for example, powdered cement and granular sand as fine aggregate. Then, the belt-like body 1 is placed in a grid pattern on the slope N, and a legal frame is formed by curing the dry mortar M. The size of the band 1 is not limited to the above, and a band having an appropriate size is prepared depending on the size of the slope N or the like. For example, a belt-like body having a width W of 0.2 m, a length L of 10.0 m, and a thickness a of 5 mm (in the roll state, 14 kg / roll (= 7 kg / m ² )), or
There is a belt-like body having a width W of 0.2 m, a length L of 10.0 m, and a thickness a of 8 mm (24 kg / roll (= 12 kg / m ² ) in a roll state).

In this embodiment, a case where cement and sand as a fine aggregate are used as the hardened material accommodated in the band 1 will be described. However, the present invention relates to cement and sand as a fine aggregate. Needless to say, the present invention can also be applied to materials mixed with gravel, gravel, crushed stone, and the like as coarse aggregates. Further, for the aggregate constituting the dry mortar M, pumice (for example, pearlite) or the like can be used. Further, for example, a reinforcing material such as steel fiber may be mixed in the dry mortar M so that the effect of improving the strength of the band 1 after curing may be obtained.

  The upper sheet portion 2 and the lower sheet portion 3 have the same configuration and have a rectangular shape in a plan view having two short sides m facing each other and two long sides n facing each other (see FIG. 4). For example, the upper sheet portion 2 has a three-layer structure in which a water-soluble film 6, a perforated multi-sheet 7 and a net 8 are provided in order from the front surface side (front side) to the inner space S side (inner side). It is a water-permeable sheet. The lower sheet portion 3 has the same configuration as the upper sheet portion 2.

  The water-soluble film 6 cannot pass dry mortar M, and examples of the material thereof include polyvinyl alcohol and water-soluble polyester. By using the water-soluble film 6, it is possible to prevent the dry mortar M from leaking during packaging, storage, and transportation.

  The perforated multi-sheet 7 is provided to allow water to permeate inside after construction, and examples of the material thereof include vinyl chloride, polyethylene, and polyolefin. The perforated multi-sheet 7 is formed with a plurality of permeation holes 7 a having a function of allowing water used for curing the dry mortar M to permeate into the internal space S.

  The nets 8 and 8 are provided to reinforce the upper and lower two sheet portions 2 and 3, respectively. Examples of the material include polyethylene, polypropylene, vinylon, biodegradable plastic, palm fiber, and jute. Examples thereof include fibers.

  The water permeable sheet only needs to satisfy all of “curing material leakage prevention”, “water permeability”, and “strength”. In addition to the above three-layer structure, for example, a knitted fabric such as cloth Various structures such as a one-layer structure based on the above and a two-layer structure combining a nonwoven fabric and a net can be employed. The water-soluble film may be a “water-decomposable sheet” such as paper.

  In this embodiment, the four urethane members 9a having the same thickness d are sandwiched between the four edge portions A, B, C, and D (see FIG. 4) of the upper sheet portion 2 and the lower sheet portion 3, respectively. , 9a, 9b, 9b are provided. These urethane members are for preventing spillage so as not to spill the dry mortar M accommodated in the internal space S to the outside. That is, the internal space S is formed so as to be surrounded by the urethane members 9a, 9a, 9b, 9b and the upper and lower sheet portions 2, 3. The urethane member 9 a is a urethane member provided on each of the edge portions A and B along the long side n of the strip 1. On the other hand, the urethane member 9b is provided at each of the edge portions C and D along the short side m of the strip 1 and is positioned between the two urethane members 9a and 9a. And the upper sheet | seat part 2, the lower sheet | seat part 3, and urethane member 9a, 9a, 9b, 9b are sewn by the hanging thread 4 as shown, for example in FIG.

Thus, before the strips 1 and 1 are installed in a grid pattern on the slope N, a known vegetation mat (for example, a vegetation mat described in Japanese Patent No. 4969906) 10 is placed on the entire surface of the slope N. Lay down. A plurality (necessary number) of strips 1 having a width W of 0.2 m, a length L of 5.0 m, and a thickness a of 13 mm are, for example, in a roll-like state [19 kg / Winding (= 19 kg / m ² )]. Subsequently, a plurality of strips 1 are installed at equal intervals in the contour direction on the vegetation mat 10. These strips 1 are referred to as horizontal strips. Next, on the horizontal belt 1, a plurality of belt-like bodies 1 are installed at equal intervals in a direction orthogonal to the contour line direction. These strips 1 are referred to as vertical bands. FIG. 3 shows the vertical band 1. Thereby, the lattice 11 is formed. At that time, an anchor pin 12 as a fixing member is driven so as to penetrate the intersection of the horizontal belt 1 and the vertical belt 1 and the portion of the vegetation mat 10 immediately below. Subsequently, water is sprayed to all the horizontal belts 1 and the vertical belts 1, and the dry mortar M is hardened with the supply of moisture into the horizontal belts 1 and the vertical belts 1. The dry mortar M is hardened by rain. After the dry mortar M is cured, the horizontal band 1 and the vertical band 1 can maintain their shapes. In this way, a method frame (not shown) can be formed by simply attaching the horizontal band 1 and the vertical band 1 and watering work. Then, for example, a dry vegetation base material (not shown) in which plant seeds are added to and mixed thoroughly with vegetation materials directly or indirectly necessary for plant growth, such as organic materials, chemical fertilizers, soil conditioners, and water retention agents. The vegetation mat 10 may be sprayed so as to cover the vegetation mat 10 so as to have an appropriate thickness in the lattice 11 by a spraying machine. By doing so, greening of the slope N is achieved.

  A net may be stretched over the entire slope N before the vegetation mat 10 is laid. Further, a rectangular vegetation mat may be laid on the slope N in a state where the rectangular vegetation mat is fitted in the lattice 11 of the belt-like body.

  FIG. 5 shows that the sheet portion 20 having the same structure as the upper sheet portion 2 and the lower sheet portion 3 is bent, and the two upper and lower edge portions 20a and 20b are sewn along the longitudinal direction, and in the lateral direction. The belt-like body 1 is formed by sewing the urethane member 9b and the seat portion 20 in the same manner as in the above-described embodiment while interposing the urethane member 9b between the edges positioned along the edge. The embodiment of is shown.

  Moreover, in each said embodiment, although the urethane member and the sheet | seat part were sewed and the strip | belt-shaped body 1 was formed, in this invention, hot melt, heat welding (heat sealing), ultrasonic welding, It is also possible to form the band by bonding the ends of the band using an adhesion method such as staple.

  Furthermore, in the present invention, the following can be applied as a method for forming the band-like body. (1) A bag-shaped sheet body (sheet portion) formed in a bag shape (tubular shape) is filled with a curable material so as to have a desired thickness, and the mouth portion of the bag-shaped sheet body is made of urethane. It is sewn with a member interposed, or bonded by the bonding method described above. (2) Using two bag-like sheet bodies, the mouth portion of one bag-like body is inserted into the mouth portion of the other bag-like body, and the overlapped portion is sewn. Then, a band-shaped body is formed, or the overlapped portion is bonded using the bonding method to form a band-shaped body.
