I will explain.

  1 to 4 show an embodiment of the present invention. The code | symbol 1 in a figure is a slope as a greening object part of a construction site. 2 is topsoil. 3 is a greening material. Reference numeral 4 denotes a constituent of the litter layer L formed on the topsoil 2, such as litter and litter that has not been decomposed or spoiled.

  First, the manufacturing method of the greening material 3 is demonstrated. In this manufacturing method, the topsoil 2 is sampled together with the defoliation layer L formed on the topsoil 2, and the collected topsoil 2 is granulated together with the defoliation layer L to generate the greening material 3. Here, the topsoil 2 is soil on the surface side of the ground, and is deposited by mixing with organic matter decomposed by decayed leaves, fallen leaves, etc. of plants. Further, the topsoil 2 includes buried seeds, which are seeds in a dormant state of plants that naturally grow in the collection area of the topsoil 2.

  In this embodiment, the surface side of the construction site is covered with a topsoil 2 as schematically shown in FIG. 1, and the fallen leaves, branches, etc. 4 are deposited on the topsoil 2. Thus, the defoliation layer L is formed. And the slope 1 is formed by cutting the ground surface side of the said construction site using construction machines, such as a backhoe, for example, and the top soil 2 is extract | collected with the defoliation layer L together. That is, the greening material 3 is produced | generated using the topsoil 2 and the fallen leaf layer L which were extract | collected from the construction site. In addition, although the range which collects the topsoil 2 is about 100-200 mm from the ground surface including the defoliation layer L as a standard (when the thickness width of the defoliation layer L is small, it is about 50-150 mm from the ground surface). Depending on the conditions such as the geology of the construction site, it may be changed as appropriate. Moreover, when there exists a big foreign material, such as a megalith and a root stock, it is desirable to remove the foreign material and extract | collect the topsoil 2. FIG.

  Here, a method of granulating the collected topsoil 2 together with the defoliation layer L will be described. In this embodiment, the collected topsoil 2 is put into the mill device 10 together with the fallen leaf layer L, and the granulation is performed by the mill device 10. Further, along with the granulation, drying of the topsoil 2 collected together with the defoliation layer L is promoted in parallel.

  Specifically, as schematically shown in FIGS. 2 and 3, the mill device 10 includes a base 10a and a substantially cylindrical main body 10b assembled to the base 10a. The main body 10b can be rotated around the rotation axis R by manual operation or electric operation. The main body 10b is provided with a loading port 10d that can be opened and closed by a lid 10c on one side in the axial direction, and a discharge port 10f with a net 10e attached on the other side. Further, a plurality of collision bodies 11, 11 are contained in the main body portion 10b. In the illustrated embodiment, there are a plurality of substantially cylindrical collision bodies 11a and a plurality of substantially spherical collision bodies 11b. Further, supply means for forcibly supplying air into the main body portion 10b is provided on the one side of the main body portion 10a. In the illustrated embodiment, a blower pipe 12 is attached. The substantially cylindrical collision bodies 11a and 11a and the substantially spherical collision bodies 11 and 11b may have different sizes.

  And while bringing the mill apparatus 10 into a construction site, for example, the top soil 2 is granulated with the fallen leaf layer L using the mill apparatus 10. FIG. First, the collected topsoil 2 is introduced into the main body 10b through the entry port 10d together with the fallen leaf layer L. Here, the moisture absorbing material (specifically, bark compost, wood chips, charcoal, other moisture absorbing agents, etc.) that absorbs the moisture contained in the topsoil 2 and the litter layer L, together with the topsoil 2 and the litter layer L, the main body Into the part 10b. Then, the main body 10b is rotated about the rotation axis R while forcibly supplying air from the blower tube 12 into the main body 10b. At this time, the topsoil 2 and the litter and litter 4 which are constituents of the litter layer L roll together with the plurality of colliding bodies 11 and 11 inside the rotating main body 10b, while the main body 10b The collision with the inner wall 10g and the collision bodies 11 and 11 is repeated. In this way, the topsoil 2 is granulated, and the fallen leaves, branches, etc. 4 are also made fine, and the greening material 3 is generated. Note that the degree of granulation of the topsoil 2 is, for example, the rotational speed (rotational speed) of the main body 10b of the mill device 10, the driving time of the mill device 10, and the shape / size / size of the collision body 11 (11a, 11b). The number, etc., and the state of the topsoil 2 and the litter layer L (the above-mentioned litter and litter 4 etc.) (for example, the water content of the topsoil 2 and the litter layer L, the soil quality of the topsoil 2), etc. For example, in this embodiment, the granulation is performed so that the collected topsoil 2 is mainly composed of a granular material having a particle diameter in the range of 5 to 2 mm. Of course, the numerical value of the particle size may be outside the range. And the produced greening material 3 is discharged | emitted from the discharge port 10f by inclining the main-body part 10b so that the said other side may be lowered, as shown with an imaginary line in FIG.2 and FIG.3. Thereafter, the discharged greening material 3 is transported by a transport means 13 such as a belt conveyor, and is stored in a bag or container 14 such as a container bag, thereby being accommodated in a certain amount.

  Subsequently, the generated greening material 3 is mixed with a plant growth base material (for example, soil for use, artificial soil, compost, soil for customer, etc.) to generate a vegetation base material 5. Specifically, both the greening material 3 and the plant growth base material are mixed by, for example, putting them into a mixer of a spraying machine and stirring them. Here, together with the plant growth base material, for example, fertilizers (for example, ordinary chemical fertilizers, advanced chemical fertilizers, fast-acting fertilizers, slow-acting fertilizers, etc.), erosion inhibitors (for example, lime-based solidifying agents, synthetic resin-based solidifying materials) Agents, cement-based solidifying agents, etc.), moisture regulators (eg, polymeric absorbents, etc.), fiber materials (eg, short fibers, long fibers, fibers, etc.), plant growth regulators, germination promoting substances (eg, Gibberellins, etc.), growth promoting substances (eg, VA mycorrhizal fungi), soil conditioners (eg, inorganic soil conditioners, organic soil conditioners, etc.), neutralizers (eg, calcium carbonate, shell crushed materials, One or more selected from phosphoric acid-based neutralizers and the like may be added and mixed. If necessary, plant materials (for example, seeds) or microbial materials (for example, rhizobial materials, mycorrhizal fungi materials) may be added and mixed. It is desirable to pay attention to the conservation of the natural ecosystem of the construction site, such as using the same kind of plants and microorganisms that grow naturally.

Here, specific formulation examples of the vegetation base material 5 are shown in Tables 1 and 2. In addition, about the mixing examples 1-3 of the vegetation base material 5 described in Table 1, it mix | blends with an appropriate amount of water, and is produced | generated by the fluid form (slurry form).

  Thus, the vegetation base is formed on the slope 1 by spraying the generated vegetation base material 5 on the slope 1, for example. In Formulation Examples 1 to 3 of the vegetation base material 5 described in Table 1 above, because the vegetation base material 5 is generated in a fluid state (slurry state), the vegetation base material 5 is released from the hose of the spraying machine, It will be sprayed on the slope 1 as it is. Moreover, in the combination examples 4-6 of the vegetation base material 5 described in the said Table 2, while discharging | emitting the vegetation base material 5 from the hose of the said spraying machine, discharge | release water in parallel, these vegetation bases The material 5 and irrigation water are sprayed onto the slope 1 while being mixed at the tip of the hose. Here, regarding the spraying of the vegetation base material 5, the vegetation base material 5 may be sprayed directly on the slope 1 or, for example, as schematically shown in FIG. 4, a vegetation net having a fertilizer bag 20. 21 may be stretched on the slope 1 and the vegetation base material 5 may be sprayed onto the vegetation net 21. In particular, in the vegetation method shown in FIG. 4, the erosion resistance of the slope 1 to which the vegetation base material 5 is sprayed can be improved, and the vegetation base can be reliably formed on the slope 1.

  Next, the manufacturing method of the greening material 3 which consists of the above structure, the manufacturing method of the vegetation base material 5, the vegetation construction method, and the effect of the greening material 3 and the vegetation base material 5 are demonstrated. In this method for producing the greening material 3, the topsoil 2 is sampled together with the defoliation layer L, and the collected topsoil 2 is granulated together with the defoliation layer L to produce the greening material 3. At the same time, the defoliation, deciduous branches and the like 4 which are constituents of the deciduous layer L are also fine. As a result, the generated greening material 3 is mixed with the defoliation, litter, etc. 4, but the vegetation base 5 as a mixture of the greening material 3 and the plant growth base material is used as the slope 1 or the like. When spraying on the part to be planted, it becomes difficult for the fallen leaves, branches, etc. 4 to be clogged in the hose of the spraying machine. For this reason, it is not necessary to extract the topsoil 2 by removing the fallen leaf layer L so that the fallen leaves, fallen branches, and the like 4 are not mixed, and the labor of the work can be reduced. Moreover, in the generated greening material 3, in addition to the buried seeds, the defoliated leaves and deciduous branches 4 that can be used as a wood fiber material, microorganisms that inhabit the deciduous layer L, and the like Therefore, it will be a greening material useful for the conservation of the natural ecosystem of the construction site.

  In addition, since the greening material 3 is obtained by granulating the collected topsoil 2 together with the defoliation layer L, the water content is reduced and the viscosity is low. In mixing, it is easy to disperse and can be sufficiently mixed. Moreover, when mixing both by stirring with the mixer etc. of the said spraying machine, there is little possibility that the greening material 3 may stick to the inner wall of a mixer and will prevent the mixing.

  Moreover, while bringing the mill apparatus 10 into a construction site and using the mill apparatus 10 and granulating the topsoil 2 together with the defoliation layer L, the greening material 3 and the vegetation base material 5 are generated at the construction site. The construction period can be shortened. Moreover, by granulating using the mill apparatus 10, for example, even when the topsoil 2 contains a large amount of water and has a high viscosity, the topsoil 2 can be granulated reliably. . Moreover, since the topsoil 2 can be granulated together with the defoliation layer L by a device having a simple structure like the mill device 10 in the illustrated embodiment, the cost can be reduced.

  Moreover, by carrying out the drying acceleration in parallel with the granulation, a decrease in the water content of the topsoil 2 and the defoliation layer L is promoted, and the greening material 3 having a low viscosity can be efficiently generated. In particular, when the moisture absorbing material such as wood chips is put into the main body 10b of the mill apparatus 10 together with the topsoil 2 and the fallen leaf layer L, the drying acceleration can be easily and reliably performed. it can.

  Moreover, in the manufacturing method of this vegetation base material 5, it is not necessary to extract | cover the topsoil 2 so that the said fallen leaves, falling branches, etc. 4 may not mix, and the effort of a work can be reduced. Then, the above-mentioned greening material 3 (that is, the greening material 3 in which, in addition to the buried seeds, the defoliation and litter 4 and the microorganisms are mixed) and the plant growth base material are mixed, The vegetation base 5 useful for the conservation of the natural ecosystem of the earth can be generated.

  Further, in this vegetation method, it is not necessary to collect the topsoil 2 so that the above-mentioned fallen leaves, litters, etc. 4 are not mixed, and the labor of the work can be reduced. And the vegetation base formed by mixing the above-mentioned greening material 3 (that is, the greening material 3 in which the defoliation, litter, etc. 4 and the microorganisms are mixed in addition to the buried seeds) and the plant growth base material Since the material 5 is sprayed on the slope 1, it is a vegetation method useful for the conservation of the natural ecosystem of the construction site.

  In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, the above-described mill device 10 may be used to granulate the topsoil 2 using the other mill device or other means without granulating the entire fallen leaf layer L. Moreover, about the compounding example of the vegetation base material 5, it is not limited to the structure mentioned above.

  In addition, it is not always necessary to generate the greening material 3 using the topsoil 2 and the litter layer L collected from the construction site. For example, the topsoil sampled from around the construction site and the topsoil are formed. The greening material 3 may be generated using the defoliation layer.

  In this embodiment, as means for promoting the drying, the moisture absorbing material is charged into the main body 10b of the mill apparatus 10 and the air is forcibly supplied into the main body 10b. However, only one of them may be performed. Further, other means for promoting drying, for example, heating of the main body 10b or supply of hot air into the main body 10b may be performed. Furthermore, a plurality of means for promoting drying may be appropriately combined. Moreover, drying acceleration may be omitted if not necessary.

  Further, the generated greening material 3 may be directly put into, for example, a mixer of the spraying machine, without being stored in a bag or container 14 such as a container bag.

  Further, the generation of the greening material 3 (that is, granulation of the topsoil 2 collected together with the defoliation layer L) is not necessarily performed at the construction site. For example, the topsoil 2 collected together with the defoliation layer L is once transported to the factory. At the same time, the whole defoliation layer L may be granulated at the factory. Moreover, the greening material 3 produced | generated at the construction site may be once carried to a factory. As described above, the greening material 3 generated in the factory or transported to the factory may be stored in the factory for a certain period and used as necessary. That is, prior to the formation of the vegetation base on the part of the construction site to be planted, the greening material 3 is generated in advance and stored in the factory for a certain period of time, and the formation of the vegetation base on the part of the construction site to be planted is started. Depending on the situation, it may be carried from the factory to the construction site. Similarly, the generation of the vegetation base material 5 (that is, the mixing of the greening material 3 and the plant growth base material) may be performed at the factory, or the vegetation base material 5 generated at the construction site is once returned to the factory. You can carry it. And the vegetation base material 5 produced | generated in the factory or carried to the factory may be stored in the factory for a fixed period, and may be used as needed.

  Even if the vegetation base 5 is not sprayed on the slope 1, for example, as shown in FIG. 5, a vegetation mat 31 having a vegetation base accommodating portion 30 is installed on the slope 1 and the vegetation mat 31 is installed. The vegetation base material 5 may be injected into the vegetation base material accommodation unit 30. Specifically, the vegetation mat 31 has a substantially rectangular shape in plan view (in the illustrated embodiment, a rectangular shape), and includes a plurality of vegetation formed in a net bag shape by a fiber material such as synthetic fiber, for example. The base material accommodating parts 30 and 30 are provided. In the illustrated embodiment, the plurality of vegetation base material accommodating portions 30, 30 communicate with each other along the longitudinal direction of the vegetation mat 31 (in the illustrated embodiment, the vertical direction of the slope 1). It is continuously deployed. And the injection | pouring hose 33 is inserted in the injection port 32 provided in the vegetation base material accommodating part 30 of the vegetation mat 31 at the one end (in the illustrated embodiment, the lower end) side, and the vegetation base material 5 is injected.

  In this vegetation method, the vegetation base 5 as a mixture of the vegetation material 3 and the plant growth base material is vegetated although the greening material 3 is mixed with the deciduous leaves, twigs, and the like 4. When injecting into the mat 31, it is difficult to cause the fallen leaves, branches, etc. 4 to be clogged in the injection hose 32 or the like. For this reason, it is not necessary to extract the topsoil 2 by removing the fallen leaf layer L so that the fallen leaves, fallen branches, and the like 4 are not mixed, and the labor of the work can be reduced. And the vegetation base formed by mixing the above-mentioned greening material 3 (that is, the greening material 3 in which the defoliation, litter, etc. 4 and the microorganisms are mixed in addition to the buried seeds) and the plant growth base material Since the material 5 is injected into the vegetation base accommodating portion 30 of the vegetation mat 31 installed on the slope 1, it is a vegetation method useful for the conservation of the natural ecosystem of the construction site.

  In addition, a vegetation sandbag in which a vegetation base material 5 is accommodated in a sandbag bag may be installed on the slope 1 to form a vegetation base on the slope 1. Also for the vegetation sandbag, the above-mentioned greening material 3 (that is, the greening material 3 in which the defoliated leaves, twigs 4 and the microorganisms are mixed in addition to the buried seeds) and the plant growth base material are mixed. Since the vegetation base material 5 is accommodated, it is beneficial for the conservation of the natural ecosystem of the construction site.

  Further, as schematically shown in FIG. 6, the vegetation mat 41 in which the vegetation base material 5 is accommodated in the vegetation base material accommodating portion 40 is placed on the slope 1, for example, to the slope 1. A vegetation base may be formed. In the illustrated embodiment, the vegetation mat 41 includes a net-like outer bag portion 42 and an inner bag portion 43 attached to the outer bag portion 42, and the inner bag portion 43 is the vegetation base material accommodating portion. 40. Specifically, the outer bag portion 42 is formed in a net bag shape with a fiber material such as synthetic fiber, for example, and the inner bag portion 43 is made of a highly corrosive material (for example, a fiber such as natural fiber or cellulose fiber). The material is used to form a bag. Further, an erosion preventing sheet 44 for preventing erosion of the slope 1 is provided on the back side of the vegetation mat 41. And also about this vegetation mat 41, the above-mentioned greening material 3 (that is, the greening material 3 in which the deciduous leaves, twigs 4 and the microorganisms are mixed in addition to the buried seeds) and the plant growth base material Since the vegetation base material 5 formed by mixing the vegetation is accommodated, it is beneficial for the conservation of the natural ecosystem of the construction site.

  Further, as a vegetation method using the greening material 3, for example, the greening material 3 may be directly sprayed on the slope 1. Even in this vegetation method, it is not necessary to collect the topsoil 2 so that the above-mentioned fallen leaves, branches, etc. 4 are not mixed, and the work effort can be reduced. Then, the above-mentioned greening material 3 (that is, the greening material 3 in which the defoliation, litter, etc. 4 and the microorganisms are mixed in addition to the buried seeds) is spread on the slope 1, so It is a vegetation method that is beneficial for ecosystem conservation.
