Description

  The present invention relates to a greening tool and a greening method suitable for greening a slope.

  Conventionally, a revegetation plant in which a revegetation tool composed of a bag-like body containing a base material together with vegetative seeds (plant planting seeds) and a net-like member on which a plurality of the pouch-like bodies are mounted is installed on the slope. Has been implemented.

  In the revegetation work, the vegetation base is formed in a stepped shape on the mountain side of the bag-like body by the washed-out sediment deposited by wetting with the bag-like body, the leaves of the trees from the surroundings, etc. By the so-called small stage effect, greening will be realized early and well. In other words, the stage effect referred to here is an effect that a growth base layer having a gentler slope than the slope is formed in a step shape due to the accumulation of earth and sand, and plants easily grow in this step.

JP-A-6-26055

  However, the base material in the bag-like body used in the greening process is mainly composed of organic matter and vermiculite, and is consumed due to elution and friction of fertilizer components. And with this diminution, the vegetation base shed and slid down from the gap or the upper side of the bag-like body between the slope and the greening device installed on this slope, and the bag-like body There is a problem that the vegetation base is not formed on the mountain side, and as a result, the step effect cannot be obtained.

  The present invention has been made in consideration of the above-mentioned matters, and its object is to provide a greening tool and a greening method capable of achieving good early greening without being affected by the reduction of the base material in the bag-like body. It is to be.

  In order to achieve the above object, a first greening tool of the present invention includes a bag-like body containing a base material, and the base material and / or the bag-like body includes a curable material that is cured by water absorption. It is characterized (claim 1).

  In addition, the second greening tool of the present invention includes a bag-like body containing a base material, and a curing material that is cured by water absorption is fixed to one or both sides of the sheet-like body constituting the bag-like body. (Claim 2).

  Furthermore, the third planting tool of the present invention comprises a bag-like body containing a base material, and the bag-like body has a double structure comprising an inner bag body and an outer bag body, and these two bag bodies A curable material that is cured by water absorption is disposed therebetween (claim 3).

  The first to third greening tools may include a net-like, mat-like or sheet-like member on which the bag-like body is mounted (Claim 4).

  On the other hand, the greening method of the present invention is characterized in that the greening tool according to any one of claims 1 to 4 is laid on a slope (claim 5).

  According to the invention which concerns on Claims 1-4, the greening tool which can aim at favorable early greening without being influenced by the reduction | decrease etc. of the base material in a bag-shaped body is obtained.

  Specifically, in the invention according to claim 1, earth and sand etc. accumulate on the mountain side of the bag-like body arranged on the planting target area such as a slope, and a vegetation base is formed in a step shape, and the plant grows in this step. The so-called small stage effect that facilitates the introduction of vegetation to the greening target area makes it possible to obtain a greening tool that contributes to the greening of the greening target area. And since the hardening material is contained in the base material or bag-like body of this greening tool, if moisture is supplied by rain or the like and the hardening material is hardened, the shape of the bag-like body at that time is maintained. It will be. Therefore, even if the base material is consumed and severe loss occurs, the vegetation base formed on the mountain side of the bag-like body is securely held by the bag-like body whose shape is maintained, and the above-mentioned step effect is sufficiently exhibited. The From the above, if this greening tool is used, the greening of the greening target area can be reliably realized in a short period of time. Furthermore, by using the base material as a vegetation base material having a function of growing vegetation seeds, the greening of the greening target land can be realized earlier and in a favorable manner.

  In addition, since the hardening of the curable material starts by supplying moisture to the greening tool after being installed in the greening target site, the bag-like body containing the base material has no irregularities in the greening target site. The shape along the unevenness will be maintained as it is. Thereby, a gap is not formed between the greening target site and the greening tool installed in the greening target site immediately after the installation of the greening tool, and the step effect cannot be obtained due to this gap. There is no problem.

  The invention according to claim 2 and claim 3 also provides a greening tool that exhibits the same effect as the invention according to claim 1.

  In the invention according to claim 4, since the bag-like body can be held by the net-like, mat-like or sheet-like member, the installation work of the bag-like body can be easily performed, and after the installation The greening tool which can keep a state favorable is obtained.

  And since the greening method which concerns on Claim 5 can be performed only by laying the greening tool which concerns on Claims 1-4 in the greening target site, it is very excellent in workability. In this case, by laying the bag-like body of the greening tool according to claims 1 to 4 along the contour line, earth and sand are deposited on the mountain side of the installed bag-like body, and this accumulated earth and sand is used as a growth base. The step effect as described above that plants (such as plant seeds flying from the periphery) are easily rooted is obtained, and as a result, the plant grows well and the greening coating on the slope is realized at an early stage. In this case, it also contributes to the improvement of the landscape.

  Further, in the greening tool according to claims 1 to 4 and the greening method according to claim 5, once the base material or bag-like body is installed in the greening target site, the maintenance and the like are almost unnecessary. It is very easy to manage.

  FIG. 1 is an explanatory diagram schematically showing the configuration of a greening method and a greening tool 1 used in the greening method according to the first embodiment of the present invention, and FIG. 2 is a schematic diagram of the configuration of the greening tool 1. It is a perspective view shown in FIG. As shown in FIG. 1, the greening tool 1 according to this embodiment is configured to allow a plant for greening to grow well on the slope N while being laid on the slope N.

  First, the configuration of the greening tool 1 will be described. As shown in FIGS. 1 and 2, the greening tool 1 includes an elongated bag-like body 3 that accommodates a base material 2. The base material 2 may be a vegetation base material including a seed selected from a plant for greening (hereinafter referred to as vegetation seed), a growth auxiliary material (water retention material, fertilizer, etc.) or a soil improvement material. It may be another normal base material, or may be a mixture of a vegetation base material and a normal base material, but at least one of the constituent materials of the base material 2 is a material that causes a loss of weight. The present invention is most effective when the blending ratio is 30% or more (more preferably 50% or more). Examples of the vegetation substrate include those containing the above vermiculite as a main component and containing vegetation seeds, and a topsoil seed bank. Specifically, vegetation seeds such as natural grounds and forests in the vicinity of the planting target area are included. A material obtained by appropriately mixing growth aids such as peat moss, bark compost, and water retention material in the topsoil containing slag. In addition, the normal base material includes a base material appropriately selected from materials that do not harm vegetation such as wood chips, agricultural and fishery waste (shells, rice husks, fruit wastes, etc.), paper sludge, etc. Materials. In this embodiment, since a vegetation base material is used as the base material 2, it is hereinafter referred to as a vegetation base material 2.

  In this embodiment, the vegetation base material 2 includes a granular or powdery curable material 4 (see FIG. 3) that is cured by water absorption. Examples of the curable material 4 include cement-based materials and gypsum.

  On the other hand, the bag-like body 3 is formed using a sheet-like body 3a that does not pass through the vegetation base material 2 and has water permeability. Here, the sheet-like body 3a is formed of, for example, a nonwoven fabric, felt, cloth (woven fabric), knitted fabric, jute cloth, water-decomposable plastic, thin cotton, or the like. Moreover, the sheet-like body 3a is configured so as not to inhibit the passage of vegetation seeds accommodated in the bag-like body 3.

  And the bag-shaped body 3 which has the said structure is accommodated in the accommodating part 6 provided in the net-like member 5 laid by the slope N, as shown in FIG. 1 and FIG. Held at 5. That is, the storage portion 6 is formed in a bag shape, a cylindrical shape, or a pocket shape having a size that can accommodate the bag-like body 3, and the bag-like body 3 is formed from one end side of the storage portion 6 to the inside thereof. Inserted. The net-like member 5 is provided with a plurality of accommodating portions 6 at appropriate intervals.

  The net-like member 5 is made of a highly durable fiber (for example, a fiber such as nylon, polyester, aramid, carbon, glass, polyacetal) or a corrosive fiber (for example, a fiber such as insulator), and has a mesh size of 5 to 10 mm. Although it is formed into a lattice shape of the degree, it may be braided into a mesh body having the same scale as described above using the filaments of the fibers, and both of these (lattice body and mesh body) You may superimpose. Further, as shown in FIG. 1, the net-like member 5 of this embodiment has a flexibility that is more than the level that can be stretched along the slope N even if the slope N is uneven. The same applies to the bag-like body 3.

  And the greening method of this embodiment is completed only by laying the greening tool 1 on the slope N as shown in FIG. In order to lay the greening tool 1, the greening tool 1 may be fixed to the slope N by placing a fixing member 7 such as an anchor pin. In addition, laying the greening tool 1 so that the bag-like body 3 is along the contour line with respect to the slope N, the plant is rooted in the soil accumulated on the mountain side of the bag-like body 3, and the greening is made earlier. And it is desirable in that the step effect that can be achieved satisfactorily is obtained, and further desirable in terms of landscape improvement.

  FIGS. 3A and 3B are explanatory views schematically showing changes in the state of the greening tool 1 laid on the slope N, and FIGS. 4A and 4B are greening by the greening method. It is explanatory drawing which shows the background of this roughly. Inside the bag-like body 3 of the greening tool 1 laid on the slope N as described above, in the initial state, as shown in FIG. 3A, the hardening material 4 and other materials contained in the vegetation base material 2 Are in a mixed state. Moreover, the bag-like body 3 is arranged in a state along the slope N without a gap due to its own weight.

  Then, as shown in FIGS. 3B and 4A, the curable material 4 is cured with the supply of moisture into the bag-like body 3 due to rain or the like. After the curable material 4 is cured in this way, the shape is maintained even if materials other than the curable material 4 in the vegetation base material 2 are consumed, whereby the bag 3 is brought into close contact with the slope N. Since the state is maintained, as shown in FIG. 4 (B), the vegetation base 8 is reliably formed, for example, by depositing runaway sand on the mountain side of the bag-like body 3, and the above-mentioned step effect is obtained. Moreover, since the said hardening material 4 hardens | cures in porous shape, the bud and the young root from the vegetation seed in the vegetation base material 2 are sewn and stretched by the space | gap of the hardening material 4, and the growth is not inhibited. .

  By carrying out the greening method of laying the greening tool 1 on the slope N as described above, the vegetation seeds in the vegetation base material 2 housed in the bag-like body 3 germinate and grow, and more aggressive greening It can be performed. In addition, plants also germinate and grow on the vegetation base 8 formed on the mountain side of the bag-like body 3. Therefore, the greening coating of the slope N is surely performed on the entire surface.

  Here, when the greening method is performed, the greening tool 1 integrated in advance may be laid on the slope N. For example, the greening tool 1 in a state in which the bag-like body 3 is not attached is used. After the arrangement on the surface N, the bag-like body 3 may be inserted into the housing portion 6. In this case, the greening tool 1 is reduced in weight and can be transported to the slope N with a small number of people. .

  Moreover, the said bag-shaped body 3 is not restricted to what is a long and slender bag shape, as shown in FIG. 1 and FIG. 2, For example, the bag shape whose aspect ratio is substantially the same may be sufficient. In this case, the configuration of the accommodating portion 6 of the net-like member 5 that holds the bag-like body 3 may be appropriately changed according to the bag-like body 3.

  Furthermore, the net-like member 5 is formed using a biodegradable material such as soft cotton, pulp fiber, synthetic resin, a soluble material, or a water-degradable material, and passes water and plant buds and roots. A sheet-like member (not shown) configured as described above may be provided by an appropriate means such as sticking. In this case, a vegetation base material, which is appropriately selected from vegetation seeds, fertilizers, soil improvement materials, water retention materials, and the like, is attached to the lower surface of the sheet-like member using a water-soluble paste material, thereby It is desirable that the shape member is configured to carry the vegetation base material. The sheet-like member 7 can also be formed by thinly extending a thin cotton made of rayon.

  The sheet-like member and the net-like member 5 may be directly fixed by sticking or the like. For example, after the sheet-like member and the net-like member 5 are arranged on the slope N in a stacked state, the anchor By placing the fixing member 7 such as a pin, both can be laid on the slope N.

  Moreover, the said greening method performed by laying the said greening tool 1 should just be implemented in a greening target site, The said slope N is only what was mentioned as an example of this greening target site, Needless to say, the greening method may be carried out in a greening target area such as a flat land. However, the greening method is more suitable for implementation on the slope N in that the step effect is obtained.

  FIG. 5 is an explanatory diagram schematically showing the configuration of the greening method according to the second embodiment of the present invention and the greening tool 9 used in the greening method. Note that members that are the same as or equivalent to those shown in the first embodiment are given the same reference numerals, and descriptions thereof are omitted.

  In the greening tool 1 of the first embodiment, the vegetation base material 2 includes the curable material 4, but in the greening tool 9 of the second embodiment, the sheet-like body 3a constituting the bag-like body 3 is provided. The curable material 4 is included, and accordingly, the vegetation base material 2 does not include the curable material 4.

  Specifically, as shown in FIG. 5, the sheet-like body 3 a is formed in a net-like shape that does not allow the vegetation base material 2 to pass through, and the outer surface of the sheet-like body 3 a is powdery. The curable material 4 is applied or fixed.

  The configuration of the greening tool 9 other than the above points is the same as that of the greening tool 1 of the first embodiment. The greening method of the second embodiment using the greening tool 9 is performed in the same manner as the greening method of the first embodiment using the greening tool 1. Accordingly, a repetitive description thereof will be omitted.

  After the greening tool 9 is laid on the slope N, when moisture is supplied to the outer surface of the bag-like body 3 due to rain or the like, the curable material 4 applied to the sheet-like body 3a constituting the bag-like body 3 is cured. To do. Thereby, even if the vegetation base material 2 is consumed and reduced, the bag-like body 3 itself is cured in the same shape, and the close state to the slope N is maintained. The vegetation base 8 is reliably formed, for example, by sedimentation of runaway sand on the mountain side of the body 3, and the above-mentioned stage effect is obtained. Further, since the sheet-like body 3a is cured in a net-like shape by the hardening material 4, the shoots and young roots from the vegetation seeds in the vegetation base 2 are stretched by stitching the mesh of the sheet-like body 3a, and the growth is inhibited Will never be done.

  That is, the same effect as the greening method of the first embodiment can also be obtained by the greening method of the second embodiment.

  In the second embodiment, the curable material 4 is not applied or fixed to the outer surface of the sheet-like body 3a. It may be formed.

  Here, the bag-like body 3 shown in FIG. 5 is configured by forming the sheet-like body 3a constituting the bag-like body 3 into a net-like shape, and applying a curable material 4 to the sheet-like body 3a. For example, as shown in FIGS. 6A and 6B, the curable material 4 may be fixed to one surface of the sheet-like body 3 a constituting the bag-like body 3. That is, FIGS. 6A and 6B are explanatory views schematically showing configurations before and after the modification of the bag-like body 3 is formed.

  Specifically, first, as shown in FIG. 6 (A), a sheet-like body 3a in which the curable material 4 is fixed (printed) in a lattice shape on one surface is formed, and thereafter, as shown in FIG. 6 (B). Furthermore, the sheet-like body 3a may be rounded into a cylindrical shape so that the surface to which the curable material 4 is fixed is inside, and the bag-like body 3 containing the vegetation base material 2 may be formed by closing the edge. . The curable material 4 can be fixed to the sheet-like body 3a using, for example, an adhesive.

  And in this case, you may comprise the bag-like body 3 so that the said hardening material 4 may be in the state fixed to the outer surface instead of the inner surface of the sheet-like body 3a, and the hardening material 4 is the sheet-like body 3a. You may comprise the bag-like body 3 so that it may be in the state fixed to both inner and outer surfaces. Furthermore, the curable material 4 is not limited to the one fixed in a lattice shape to the sheet-like body 3a, and may be fixed in a stripe shape, for example.

  Moreover, you may comprise the said bag-like body 3 as shown in FIG. That is, FIG. 7 is an explanatory view schematically showing the configuration of another modified example of the bag-like body 3, and as shown in this figure, the bag-like body 3 is made from the inner bag body 10 and the outer bag body 11. The curable material 4 may be disposed between the bags 10 and 11.

  Specifically, the inner bag body 10 containing the vegetation base 2 is housed in the outer bag body 11, and the curable material 4 is previously placed on the outer surface of the inner bag body 10 or the inner surface of the outer bag body 11. Is fixed. This fixing can be performed using, for example, an adhesive.

  In this case, when it is considered that the vegetation seed buds and radicles in the inner bag body 10 cannot penetrate the cured material 4 and inhibit its growth, the outer surface of the inner bag body 10 or the outer The curable material 4 is fixed to the inner surface of the bag 11 so as to have, for example, a lattice shape or a striped shape, and the cured material 4 in which the growing shoots and roots are cured can be avoided. It is desirable.

  1-7 may be arrange | positioned independently on the slope N using appropriate fixing members, such as the anchor pin 7 and a pile. In this case, since the net-like member 5 or the like is not necessary, a greening method that can be performed more inexpensively and easily can be obtained.

  Further, in the first embodiment, the vegetation base material 2 includes the curable material 4, and in the second embodiment the curable material 4 is included in the bag-like body 3 by means such as fixing. The curable material 4 may be included in both the material 2 and the bag-like body 3.

  Further, the bag-like body 3 shown in FIGS. 1 to 7 is used as a fertilizer bag for a vegetation mat described in the specification and drawings attached to the application of Japanese Patent Application No. 2005-089970 relating to the earlier application of the present applicant, and / or Or it is very effective if used as a base material bag. Specifically, FIG. 8 is a perspective view schematically showing the configuration of the vegetation mat. As shown in this figure, the vegetation mat is configured by attaching the bag-like body 3 to a three-dimensional (three-dimensional) net 12. Is done.

  The three-dimensional net 12 connects the first net 13 disposed on the slope as a greening target site, the second net 14 suspended above the first net 13, and both nets 13, 14. A saddle stitch thread 15 and a thin cotton 16 provided below the first net 13 are provided.

  The three-dimensional net 12 has a substantially cylindrical housing portion 17 in which the bag-like body 3 is housed. That is, the saddle stitch thread 15 that connects the first net 13 and the second net 14 is provided at an appropriate interval, but the saddle stitch thread 15 is not intentionally provided in a part of the three-dimensional net 12. The housing portion 17 is formed. Therefore, the accommodating part 17 becomes a structure which hold | maintains the bag-like body 3 inserted from the side between the 1st net | network 13 and the 2nd net | network 14 with both net | networks 13 and 14 and the saddle stitch thread 15. FIG. ing. Although FIG. 8 shows only one accommodating portion 17, in actuality, a plurality of accommodating portions 17 are provided at appropriate intervals.

  When the three-dimensional net 12 having the above configuration is laid on a greening target land (for example, a slope) and the bag-like bodies 3 are accommodated in the plurality of accommodating portions 17, the second net 14 is formed by the self-tension and the bag-like body 3. The first net 13 is lifted by lifting. Therefore, in the greening target area where the vegetation mat is laid in this way, the flying seed that has fallen on the greening target ground directly or colliding with the second net 14 is held by the first net 13 or the thin cotton 16, The scattering is prevented by the second net 14 serving as a windbreak. That is, the vegetation mat has an excellent flying seed capturing performance.

  The bag-like body 3 is cured when moisture is supplied by rain or the like and maintains its shape for a long period of time, so that the three-dimensionality of the three-dimensional net 12 is also maintained for a long period of time. It can prevent that the said flying seed capture | acquisition performance of a vegetation mat reduces.

  Here, when the three-dimensional net 12 is laid on the slope, it is desirable that the bag-like body 3 accommodated in the accommodating portion 17 is arranged along the contour line from the viewpoint of obtaining the step effect. Furthermore, in this case, it is possible to appropriately reduce the size of the portion forming the accommodation portion 17 in the second net 14 so that the mountain side of the bag-like body 3 accommodated in the lower portion in the accommodation portion 17 (that is, the accommodation portion). 17 is preferable in that it can prevent the seeds flowing into or flying into the upper part).
