Description

  TECHNICAL FIELD The present invention relates to a hybrid planting material for natural plants and artificial turf, and in particular to a planting material installed on a load-loaded installation surface such as a parking lot or a road.

  If you lay the lawn on a load-loaded installation surface, such as a parking lot or a road, the lawn can not bear the load and is damaged, weakened, and withered. Patent Document 1 discloses a structure for protecting a lawn under such an environment. The structure of Patent Document 1 is a honeycomb structure made of hard plastic and having a large number of cavities, in which the lawn is grown. Therefore, even if a large load is applied as the vehicle runs, the load is dispersedly received by the structure, thereby protecting the lawn.

  By the way, sufficient water, sunlight, etc. are required for nurturing natural turf. Therefore, natural turf may deteriorate in color or wither. Patent Document 2 discloses a greening material in which a string-like artificial turf is combined with the structure of Patent Document 1 so as to maintain a good appearance even in such a case. More specifically, it is disclosed that while the string-like artificial turf is stretched around the structure of Patent Document 1, at the same time, natural turf is grown in the cavity.

<1. First embodiment>
<1-1. Overall composition of greening materials>
The greening material 1 according to the present embodiment is a hybrid type of greening material of a natural plant and an artificial turf. The greening material 1 is a material for heat island measures and global warming measures, and is used to green the ground of the parking lot in this embodiment. However, the present invention is not limited to this example, and the greening material 1 can be preferably used on any installation surface G to which a load is applied, such as a road. The type of the installation surface G is not particularly limited, such as soil, asphalt, bricks, tiles, interlocking blocks, and the like.

  The partial side sectional view of the material 1 for greening is shown in FIG. As shown in the figure, the greening material 1 includes a partition structure 2 having a plurality of cavities S1, and further includes a water retaining layer 3, an artificial turf mat 4, a base layer 5 and the like disposed in the cavities S1. A natural plant 6 is provided. The partition structure 2 is disposed on the installation surface G such that the plurality of cavities S1 are continuously arranged in a plane substantially parallel to the installation surface G. Each cavity S1 is open toward the top. A water holding layer 3 is formed at the lowermost portion in each hollow S1, and a mat 4 of artificial grass is laid on the water holding layer 3. The base layer 5 is formed on the base material 41 of the mat 4 of artificial turf, and the natural plant 6 is planted using the base layer 5 as a growing bed. The partition structure 2 protects the natural plant 6 and the base layer 5 to be a growth bed thereof in the cavity S1. The partition structure 2 can prevent the natural plant 6 and the base layer 5 from being stowed even under a situation where vehicles, pedestrians, etc. frequently move thereon, and can support the growth of the natural plant 6 it can. The details of each part will be described below.

<1-2. Details of each part>
<1-2-1. Partition structure>
FIG. 2 is a plan view of the partition structure 2 alone, and FIG. 3 is a partial perspective view thereof. As shown to these figures, the partition structure 2 has the partition wall 21 which divides several cavity S1, and each cavity S1 is extended in an up-down direction. The partition wall 21 plays the role of a post. In addition, the up-down direction here is defined on the basis of the state of FIG. The partition structure 2 according to the present embodiment is a honeycomb structure. That is, the respective cavities S1 have a substantially hexagonal shape in a plan view, and the cavities S1 are mutually arranged in a close-packed manner in plan view. The upper portion of each cavity S1 is open and forms a substantially hexagonal opening. On the other hand, the bottom surface portion 22 is formed in each cavity S1, and a circular opening 22a is formed in the lower center of the bottom surface portion 22.

  Each cavity S1 is defined by a plurality of (in the present embodiment, six) substantially rectangular flat partition walls 21. The partition walls 21 as a whole are cylindrical (in the present embodiment, substantially hexagonal tubular) Form the structure of Each of the substantially rectangular flat partition walls 21 is formed with a notch 21a which is cut out by a predetermined depth from the upper end side at a substantially central portion of the upper end side. The cavities S1 communicate with each other.

  The partition structure 2 is made of a hard material, and in the present embodiment, is made of hard plastic, and is made of polypropylene, polyethylene or the like. However, the material of the partition structure 2 is not particularly limited as long as it can exhibit strength to withstand a load passing thereon, such as a vehicle or a pedestrian, and, for example, other types of plastic, various types It can be made of an elastomer or it can be made of metal. Moreover, it is preferable to select a material having high durability to rust and the like.

  The size of the partition structure 2 can be appropriately selected, and can be, for example, 600 mm × length 2500 mm. When the greening material 1 is introduced and installed, a suitable number of partition structures 2 are arranged to fill the installation surface G.

<1-2-2. Water holding layer>
As shown in FIG. 1, the water holding layer 3 is formed at the lowermost portion in each cavity S1. The water holding layer 3 has a water holding function, is disposed under the base material 41 of the mat 4 of the artificial turf in each cavity S1, and plays a role of holding water to be given to the natural plant 6. The water retention layer 3 of the present embodiment is made of non-woven fabric, but is not limited thereto. For example, cloth other than non-woven fabric, cotton, sponge, coil, porous material (brick, tile, pumice, etc.), soil, sand It can also be composed of resin pellets, water-absorbing polymer materials, plant roots, sawdust, wood chips, cup-shaped vessels. When the water retaining layer 3 is made of non-woven fabric, cloth other than non-woven fabric, cotton, sponge, coil or the like, the water retaining layer 3 also functions as a cushioning layer. In this case, the water retention layer 3 can protect the natural plant 6 from external force caused by stepping on a vehicle, a pedestrian or the like. Moreover, the water holding layer 3 can be comprised in arbitrary aspects, such as block shape, a granular form, paste shape, clay shape.

  The water holding layer 3 has a shape that fills the lower part of each cavity S1 substantially without a gap, and in the present embodiment, has a substantially hexagonal column shape. Although the thickness of the water retaining layer 3 is not particularly limited, in the present embodiment, the water retaining layer 3 occupies a range from the upper surface of the bottom surface portion 22 of each cavity S1 to the height position of the lower end of the notch 21a of the partition wall 21 .

1-2-3. Artificial grass mat>
The synthetic grass mat 4 is placed on the top surface of the water retaining layer 3 in each cavity S1. As shown in FIG. 1, the mat 4 of artificial turf has a base material 41 and a large number of piles 42 imitating turf leaves standing on the upper surface of the base material 41. The base material 41 is formed in a sheet shape, and the piles 42 are implanted on the base material 41 at predetermined intervals. The base material 41 is disposed so as to spread in a plane substantially in parallel with the installation surface G in each of the cavities S1. In addition, a backing agent is applied on the back surface side of the base material 41 in order to prevent the pile 42 from falling off, and a backing layer 43 is formed.

  The base material 41 of the present embodiment includes a layer 411 made of non-woven fabric, and has a water retention function. In addition, the base 41 includes a plain woven layer 412 made of a synthetic resin under the non-woven layer 411. As the synthetic resin, typically, a thermoplastic resin can be selected, and preferably, a polyolefin such as polyethylene or polypropylene is selected. In this manner, for example, different types of layers such as a non-woven fabric layer 411 and a non-woven fabric layer 412 may be stacked to form the base material 41 having a multi-layer structure. It is also possible to form the substrate 41 from only the layer 411 or only the layer 412 of plain woven fabric.

  The base material 41 is shaped so as to fill the respective cavities S1 substantially without a gap in a plan view. For reference, the shape of the base material 41 is shown by a dotted line in FIG. Thus, the base material 41 has a shape in which a plurality of substantially hexagonal portions 41a are connected via the short rectangular connection portion 41b in a plan view. The connection portion 41 b passes through the above-mentioned notch 21 a of the partition wall 21. Thus, the substrate 41 is continuously formed across the plurality of cavities S1 through the notches 21a.

  The material and form of the pile 42 are not particularly limited as long as the appearance of turf leaves can be realized. For example, the pile 42 can be formed using a yarn (yarn) made of a synthetic resin. The yarn may be, for example, a monofilament yarn or a split yarn. Also, the yarn may be a straight yarn or a crimped yarn. As the synthetic resin, typically, a thermoplastic resin can be selected, and preferably, a polyolefin such as polyethylene or polypropylene, or nylon is selected. The pile 42 of the present embodiment is fixed to the base material 41 by sewing the yarn to be the pile 42 into the base material 41 using a tufting machine. The cross-sectional shape of the pile 42 can be various shapes such as a triangle, a square, an oval, and a star. In addition, the mat 4 of artificial turf can be manufactured, for example, by punching and cutting the rectangular base material 41 to which the piles 42 are sewn into a shape according to the shape of the cavity S1. Moreover, the pile 42 can also be sewn to the base material 41 cut into the shape of hollow S1 previously. Alternatively, the base material 41 and the pile 42 can all be made of resin, in which case the mat 4 of artificial turf can be manufactured by injection integral molding.

  The length of the pile 42 is preferably such that it reaches near the upper end of the partition wall 21 when the mat 4 of artificial turf is installed in the cavity S1, as shown in FIG. It is more preferable that the length is slightly over the upper end. In this case, a good view of the artificial turf is easily exhibited, and a natural appearance can be exhibited even when the growth state of the natural plant 6 is not good. Further, it is unlikely that the pile 42 will be pulled out by being pulled by the foot of the vehicle or pedestrian. The pile 42 is inclined more or less by its own weight, but the length referred to here is a natural length taking into consideration such inclination. From the above point of view, it is preferable to set W2 ≦ W1 ≦ W2 + 2 cm, where W1 is the height of the grass and the length (average value) from the upper surface of the base 41 to the upper end of the dividing wall 21 is W2. The turf length W1 is a length (average value) from the upper surface of the base material 41 to the tip of the pile 42, and is a length when the pile 42 is linearly extended.

  The material of the backing layer 43 is also not particularly limited. For example, the backing layer 43 can be composed of a mixture of polyethylene and SBR latex. In addition, the backing layer 43 can also be omitted from the viewpoint of making it easy to stretch the root of the natural plant 6 and enhancing drainage performance.

  A plurality of piles 42 (eight in the example of FIG. 1) are planted at each planting point P <b> 1 on the base material 41. However, the number of piles 42 at one planting point P1 can be changed as appropriate. FIG. 4 shows the relationship between the substrate 41 and the position of the planting point P1. The circle in the figure represents the position of the planting point P1. As shown in the figure, the planting points P1 are arranged at substantially constant intervals and form multiple rows. That is, the planting points P1 are arranged in a plane substantially in a plane substantially parallel to the installation surface G, and the piles 42 are arranged in a plane in a plane substantially parallel to the installation surface G. Therefore, the color of the pile 42 can be entirely introduced into the material 1 for greening.

  Also, the color of the natural plant 6 may be degraded with yellowish or brownishness, but even in such a case, the degraded natural plant 6 may be degraded by the pile 42 that spreads uniformly in plan view as a whole. The color can be covered. In addition, the aesthetic appearance can be enhanced in a period until the natural plant 6 grows sufficiently.

1-2-4. Base layer>
The base layer 5 is disposed on the upper surface of the base 41 of the mat 4 of artificial turf in each cavity S1. The base layer 5 is a growth bed of the natural plant 6, has a water retention function, and plays a role of holding water for giving to the natural plant 6. The base layer 5 of the present embodiment is made of a plant curing material to which natural plants 6 can be rooted. Plant curing materials are composed of water absorbent fibrous materials such as paper and sawdust, and these fibrous materials are also mixed with glue. Therefore, the layer of the plant curing material forms a generally integrated aggregate at least in the state of FIG. 1, and scattering of the material is prevented. As the plant curing material, in addition to fibrous materials, soils such as diatomaceous earth, minerals such as zeolite powder, water-absorbing polymer materials, water-retaining agents such as granular cotton, etc. are appropriately combined to prepare the growth environment of the natural plant 6 Can be mixed. The glue can be omitted.

  The material constituting the plant curing material has the ability to retain moisture and is preferably excellent in the ability to fix the natural plant 6 on the surface as in the above example, but it functions as a breeding bed for the natural plant 6 As long as it can be done, it is not limited to the example mentioned above. For example, the main material of the plant curing material may be sand, resin pellets, plant roots, wood chips and the like.

  In forming the base layer 5, a material (hereinafter, a mixed material) in which the above-mentioned plant curing material and the seedling of the natural plant 6 are mixed is prepared. The mixed material at this stage is in powder form. This is filled on the base material 41 of the mat 4 of artificial turf in each cavity S1 so as to fill the root portion of the pile 42. Then, the natural plant 6 is grown while applying moisture to the mixed material and the water retaining layer 3 in each cavity S1. During the growing period, the roots of the natural plants 6 grow in a network in the base layer 5 formed of the plant curing material, and become entangled in the plant curing material and the pile 42. Thereby, the natural plant 6 is fixed on the surface of the base layer 5. In addition, since the base layer 5 is protected by the partition structure 2 mentioned above, and it does not compact, the root of the natural plant 6 is firmly grown up in the base layer 5.

  In the present embodiment, since the cavities S1 communicate with each other through the notches 21a, the root network of the natural plant 6 is formed across the large number of cavities S1. That is, beyond the dividing wall 21, the natural plant 6, the base layer 5, and the pile 42 of artificial turf are integrally connected. Although the root of the natural plant 6 depends on the kind of the natural plant 6, in some cases, the base 41 of the synthetic grass mat 4 and at least one of the inside of at least one of the backing layer 43 and the water holding layer 3 Can also grow. Also, even if the roots of the natural plant 6 can not enter into the inside of the layers 41, 43 and 3, the roots of the natural plant 6 propagate along the gaps between the dividing wall 21 and the layers 41, 43 and 3. Can grow like a network. Furthermore, the root of the natural plant 6 passes through the opening 22a of the bottom of the partition structure 2 and grows in the installation surface G if the installation surface G is soil or the like. On the other hand, if the installation surface G is asphalt or the like, the gap between the installation surface G and the bottom portion 22 can be rooted and grown.

<1-2-5. Natural plant>
The natural plants 6 are fixed on the base layer 5 in the respective cavities S1 as described above, and are grown so as to be mixed with the piles 42 on the base layer 5. At this time, the natural plants 6 grow while being spread in a plane substantially in a plane substantially parallel to the installation surface G in the respective cavities S1, and are entirely entangled and mixed with the pile 42 in a plan view of the revegetation material 1 . Therefore, since natural plants 6 are uniformly arranged between the piles 42, a natural feeling of the material for greening 1 is realized.

  In the present embodiment, a moss plant is used as the natural plant 6. Below, the reference numeral 5 may be attached also to moss plants. The type of moss plant 6 is not particularly limited, but preferred examples include snagogoke, moss and moss, and among these, snagogoke is particularly preferred.

  Many plants used for greening, including natural turf, can be laborious to maintain. For example, if it is an annual plant, it must be planted, grown and removed every season. Even perennials and evergreen species require replanting of the dead parts, often requiring frequent watering, fertilizing and harvesting. In addition, in the case of a seed plant, the wind may cause the seeds to scatter and grow spontaneously, which may disrupt the surrounding ecosystem. Furthermore, some plants require soil of a certain depth or more to spread the roots, which may not be suitable for the installation environment of the revegetation material.

  In this regard, moss plants can overcome the above problems. Moss plants do not wither only by becoming a temporary death state even if dried, and can be maintained even with rainwater because they are regenerated if water is given. In addition, since moss plants grow on spores and maintain their cells only by taking in water from the air, no fertilizer is required. Furthermore, because it is a plant that grows everywhere, there is little impact on surrounding ecosystems. In addition, moss plants grow without soil, have a low speed of corrosion even on minerals such as concrete, have a high carbon immobilization capacity, and are very useful for reducing greenhouse gases.

  However, when a moss plant enters a state of temporary death, it becomes difficult to see chloroplasts in cells, and it discolors to a yellowish or brownish color and loses its color. In this respect, in the present embodiment, even in such a case, the pile 42 can maintain the aesthetics of the greening material 1. Further, in the present embodiment, since the moss plant 6 is in a suitable shade formed by the pile 42, it is difficult to be exposed to direct sunlight. Therefore, the moss plant 6 is difficult to be dried and is not likely to be in a state of temporary death.

  The pile 42 can also play a role of windproof net protecting the natural plant 6 and plant curing material. That is, since the wind makes it difficult to directly hit the natural plant 6 and the plant curing material by the pile 42, it is suppressed that the natural plant 6 is broken or the seeds, stems and plant curing material of the natural plant 6 are blown off. Is easier to establish.

<2. Second embodiment>
Next, the greening material 101 according to the second embodiment will be described with reference to FIG. The greening material 101 according to the second embodiment is common to the greening material 1 according to the first embodiment in many respects, so the same reference numerals are given to the same components and the description will be omitted.

  The difference between the greening material 101 and 1 is that the water holding layer 3 is omitted. In the greening material 101, instead of the water holding layer 3, the mat 4 of artificial turf is arranged in the lowermost layer of each cavity S1. In this example, since the base material 41 of the mat 4 of artificial turf is at a deeper position than the notch 21a of the partition wall 21, the base materials 41 in different cavities S1 are not connected but separated from each other. .

<3. Modified example>
As mentioned above, although some embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible unless it deviates from the meaning. For example, the following modifications are possible. Moreover, the gist of the following modifications can be combined as appropriate.

<3-1>
In the above embodiment, the moss plants are grown in the material for revegetation, but instead of or in addition to this, other natural plants 6 can also be grown. The type of the natural plant 6 can be selected arbitrarily, and preferable examples include mosses, turfgrasses, herbs, ferns and the like. More specifically, in addition to mosses, natural turf, tamaryu, dicondora can be used, and so-called weeds such as clover, chickweed, dandelion, scallop, moth, and the like can also be used. In addition, it is preferable to use a plant having a low plant height, which is unnecessary or easy to cut, such as ground cover plants.

<3-2>
The plan view shape of the cavity S1 is not limited to the above-described substantially hexagonal shape, and may be, for example, a circular shape or a polygonal shape other than a hexagonal shape.

<3-3>
Although the opening 22a is formed in the bottom surface portion 22 of the partition structure 2 in the above embodiment, this may be omitted. In addition, when the opening 22a is formed, drainage is ensured, and when the opening 22a is omitted, the water retention is improved. Which configuration is adopted can be determined depending on the environment of the installation surface G of the greening material 1.

<3-4>
In the description of the above embodiment, many examples of the material and structure of the water retaining layer 3 are shown, but the water retaining layer 3 can also be configured by two or more layers selected from among these examples and further aspects. . For example, when a sponge layer and a highly water-retentive nonwoven fabric are stacked to form the water-retaining layer 3, the water retentivity and the drainage property can be compatible, and the possibility of root rot and drought of the natural plant 6 can be reduced.

  Also, as in the first embodiment, the water retention layer 3 can be disposed below the base material 41, or can be disposed on the base material 41 instead of or in addition to this. When the water retaining layer 3 is disposed on the substrate 41, the water retaining layer 3 is preferably disposed below the substrate layer 5.

<3-5>
In the above embodiment, the base material 41 has a shape in which the plurality of portions 41a corresponding to the shape of each cavity S1 are arranged in a line, but may be formed in a sheet shape in which a plurality of portions 41a are arranged in a large number of lines. The connection portion 41b may be omitted, and the portion 41a may be separated for each cavity S1.
