DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel planting unit shelf which enables greening of a wall such as a retaining wall in a place where the sunshine is poor and is not originally suitable for cultivating plants.

[0002]

2. Description of the Related Art Concrete structures such as sound insulation walls and viaducts on roads not only impair the scenery, but also reflect the sun's rays and cause environmental deterioration. Therefore, in recent years, a technique for greening the wall surfaces of these structures has attracted attention. By the way, the method of greening the wall of a building with climbing plants has been known for a long time, but in many cases, there is no soil foundation for planting plants in cities. It ’s a bad place,
In most cases, the soil is in poor condition. Therefore, there is a problem that it is necessary to improve the soil and replace the soil, which takes time. There is also a problem that it takes too long for plants to grow sufficiently and green the entire wall surface, which cannot be fundamentally solved.

Therefore, as a structure for planting directly on the wall,
JP-A-63-75142 discloses a plant cultivable panel. Further, as a configuration using no soil, Japanese Patent Application Laid-Open No. 1-94120 discloses a method for greening a slope or a vertical surface and a sheet material for greening the same.

[0004]

Among the above-mentioned conventional examples, in the above-mentioned panel capable of plant cultivation, a soil material for plant cultivation is interposed between a pair of panel materials. However, since the soil material is heavy, it is difficult to handle the panel, and since the inside is filled with soil having a large specific gravity, the strength of the structure must be increased. Further, there is a problem that the lower portion is compacted by external vibration after the installation. In order to solve this problem, in the conventional example, the partition is formed by horizontal pieces, but the compaction in the unit of section is not completely eliminated.

[0005] On the other hand, in the latter conventional example, a plant is planted on a sheet material such as a nonwoven fabric adhered to the surface of a plate material to form a panel, and the panel is fixed to a slope formed by a frame or the like. It has been disclosed. However, since the sheet material is bonded to the plate material, the plate material suppresses the growth of the roots of the plant, and there is a risk of failure in growth. Not preferred.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to green a wall surface reliably and early with a simple and lightweight structure. A suitable place for use is to attach a greening structure to the vertical retaining wall or the surface of the slope.

[0007]

According to the present invention, in order to achieve the above-mentioned object, a frame body having a plurality of through holes in each of an upper and lower plate and both side plates, and a vertical plate and a horizontal plate are respectively provided. A lattice frame having a large number of through-holes, the lattice frame is fixed in the frame to divide the inside of the frame into a plurality of planting spaces, and the plurality of planting spaces include granular cotton, A means of filling an artificial planting base material mixed with wood fiber, non-woven fabric, and the like and simultaneously planting was adopted. Further, in this unit shelf, a means of stretching a sheet-like nonwoven fabric and a net covering the nonwoven fabric on at least one of the front surface and the back surface of the frame body was selectively used. Further, a means constituted by a foamed resin material was selectively used for the frame and the lattice frame.

Further, a means for arranging a water supply pipe along the upper surface of the upper plate of the frame and a means for arranging a water supply pipe above the frame by penetrating both side plates and the lattice frame are selectively provided. Further, a means was used in which a drainage tank having a U-shaped cross section opened upward was provided on the lower surface of the lower plate of the frame body.

[0009]

By stacking a plurality of planting unit shelves for greening according to the present invention, it has an effect of attaching a greening structure to an existing wall. In addition, the planting space functions as soil for planting plants, and the granular cotton filling this space,
The artificial planting base material mixed with wood fiber, non-woven fabric, etc. has the function of water retention and ventilation, and acts as an alternative soil. Of the through holes formed in the frame, the through holes provided in the upper and lower plates function as water holes (drain holes), while the through holes provided in both side plates function as vent holes. The lattice frame acts to equalize the load on a section-by-section basis. In addition, the plurality of through holes provided in the lattice frame not only have functions of water passage and ventilation, but also give freedom to the growth of plant roots. The vegetation sheet acts as a surface soil for plant growth. The net has an effect that the vegetation sheet or the granular cotton or the like in the planting space is scattered by wind damage or the like, and that the stem is easily entangled when the vine is planted. At the same time, the net provides the structural strength of the planting unit shelf. Furthermore, when the frame and the lattice frame are made of a foamed resin material, the weight of the planting unit shelf is reduced, and the transportation and construction are facilitated.

[0010] The water supply pipe is intended to supply water to the planting space, and is intended to perform appropriate water retention management even during drying. In addition, the drainage tank has a function of draining excess water that could not be completely retained in the frame through the through hole. When constructing the wall greening structure using a plurality of planting unit shelves, a water supply pipe and a drainage tank may be provided for each, or a water supply pipe may be provided on the uppermost unit shelf, and the lowermost unit may be provided. It is only necessary to provide a drainage tank on the shelf. For this, an appropriate combination can be adopted according to the plant to be planted, the environment of the construction place, and the like.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings. First, FIGS. 1 and 2 show details of a planting unit shelf 10 of the present invention. A plurality of through holes 2... 2 are formed in upper and lower plates 1 a and both side plates 1 b constituting a frame 1. doing. A grid frame 4 composed of a vertical plate and a horizontal plate provided with a large number of through holes 3 is fixed in the frame 1 so as to partition the inside of the frame 1 into a plurality of planting spaces 5. 5
Is composed. The planting spaces 5 are filled with an artificial planting base material 6 in which granular cotton, wood fiber, non-woven fabric and the like are mixed. The mixing ratio of the artificial planting base material 6 is appropriately changed according to the plant to be planted and the environment of the construction site, and the water retention and air permeability in the planting space 5 are adjusted. Further, the artificial planting base material 6 having a different mixing ratio for each planting space 5 may be filled, and further, fertilizer may be mixed. In the planting unit shelf 10 having such a configuration, the upper and lower plates 1
2 function as water passage holes when the planting unit shelves 10 are stacked in several stages, and the through holes 2 in both side plates 1b.
.. 2 function as ventilation holes when a plurality of planting unit shelves 10 are arranged side by side. In addition, the through holes 3... 3 of the lattice frame 4 give air permeability and water permeability to the planting spaces 5.
Gives freedom to the growth of the roots of the plant, and the adjacent planting space 5
To allow it. Therefore, the planting unit shelf 10 promotes plant growth while maintaining the balance of water retention, ventilation, and water flow.

Numeral 7 denotes a drainage tank having a U-shaped cross section provided on the lower surface of the lower plate 1a, and communicates with the through hole 2 of the lower plate 1a. The reason why the drainage tank 7 is provided is to prevent the lower planting space 5... 5 from always having excessive water retention.
This is for improving the drainage cycle of water when the planting unit shelves 10 are stacked in several stages and supplying clean water. When a wall is constructed by stacking a plurality of planting unit shelves 10, the planting unit shelves 10 located at the bottom of the wall are constructed.
Only this drainage tank 7 may be provided.

Reference numeral 8 denotes a water supply pipe, which is a planting unit shelf 1
It is disposed above the reference numeral 0 so as to penetrate the side plates 1b and the lattice frame 4. The water supply pipe 8 is used to prevent the artificial planting base material 6 from drying and the plant from withering. In other words, when constructing the wall, the planting unit shelves 10 are stacked closely in the vertical direction as described later, so that only outside holes 2... 2 come into contact with the outside, and natural water supply by rainwater or the like is expected. Is difficult, the water supply pipe 8 is used to forcibly supply water. The water supply pipe 8 has a number of water supply holes formed around it. As a water supply structure, water supply conditions and the like can be properly controlled by forming a plurality of orifices on the surface of a water supply pipe and using a drip tube in which water is dripped evenly from each orifice. However, instead of this, it is also possible to use a porous water supply pipe in which fine holes are formed, and to uniformly leaching water from the entire surface of the water supply pipe with water pressure.

In the planting unit shelf 10 of the present embodiment, the water supply pipe 8 is provided so as to penetrate the both side plates 1b and the lattice frame 4. However, the wall is constructed by stacking a plurality of planting unit shelves 10. In order to avoid the bulkiness of the planting unit, the water supply pipe 8 may be arranged along the upper surface of the upper plate 1a for the planting unit shelf 10 located at the uppermost stage as shown in FIG.

Next, an embodiment of the greening of the existing retaining wall by the planting unit shelf 10 of the present invention will be described. FIG. 4 shows the vertical cross-sectional structure of the wall surface of this embodiment. Reference numeral 20 denotes the surface of an existing vertical retaining wall. Preferably, the surface is subjected to root protection coating or a root protection sheet is stretched. By
Prevent cracking of concrete due to root penetration. In the planting spaces 5... 5, it is free to adopt an artificial planting base material 6 having a higher water retention performance than the lower layer in the upper layer in order to avoid uneven water retention due to the difference in position. . Reference numeral 11 denotes a nonwoven fabric sheet provided on the front surface side of the planting unit shelf 10, which has a configuration that functions as a surface layer when planting.

When planting, the nonwoven fabric sheet 1
1 is attached to the planting unit shelf 10, a cut is made in the nonwoven fabric sheet 11 at the site, and seeds are seeded;
In some places, such as a factory, a nonwoven fabric sheet 11 with a cut is stretched and a planting unit shelf 10 in a state of germination to some extent is assembled. , Can be appropriately selected according to the scale and the like. In the means for spraying and growing seeds on the nonwoven fabric sheet 11, the entire surface of the sheet can be densely greened. On the other hand, in the means for planting previously grown plants, wall greening is completed simultaneously with construction. The construction period can be shortened.

Reference numeral 12 denotes a lattice-like net which prevents the nonwoven fabric sheet 11 and the artificial planting base material 6 from being blown off by wind or the like, and gives an appropriate pressure to the nonwoven fabric sheet 11. The net 12 is connected to the planting unit shelf 10.
In general, the net 12 itself is made of a metal net to secure the strength, made of stainless steel to prevent rust, galvanized, and further coated with a synthetic resin. It is not limited. In the present embodiment, the net 12 is formed in a lattice shape. However, the net 12 may be replaced with a stripe shape, a rhombus shape, or the shape may be changed as appropriate.

The greening retaining wall is not limited to the vertical wall of the first embodiment. For example, even if the retaining wall is an inclined wall, the planting unit shelf of the present invention can be applied. In this case, while the side plates of the frame and the vertical plates of the lattice frame are along the slope, the upper and lower plates of the frame and the horizontal plates of the lattice frame are made vertical, so that the plants planted in each planting space 5 are Adapts to phototropism and can further promote plant growth.

Next, the wall structure of the second embodiment will be described.

FIG. 5 is a front view of a retaining wall employed in the present embodiment, and FIG. 6 is a sectional view taken along the line A-A, in which recesses 30... The retaining wall can be employed for either a vertical wall or an inclined wall. This recess 30
Is equivalent to a unit partitioned by columns and beams. The configuration of the planting unit shelf 10 is not different from the first embodiment . The net 12 can be directly anchored to the retaining wall with an anchor,
Anchor bolts are erected in advance when the retaining wall is constructed, and fixed to this.

[0020]

As described above, the planting unit shelf of the present invention has a plurality of planting spaces in which the frame is divided by a lattice frame, and granular cotton, wood fiber, nonwoven fabric, etc. are provided for each planting space. Since the planting was performed by filling the artificial planting base material consisting of, it is possible to plant the entire surface of the constructed wall.
Therefore, the greening wall was completed at the same time as the construction was completed, and the wall could be greened without waiting for the plants to grow. Further, since the artificial planting base material was formed of any of granular cotton, wood fiber, and nonwoven fabric or a mixture thereof without using soil, the overall weight could be reduced. Further, when the frame and the lattice frame are made of a foamed resin, the overall weight can be further reduced, and the workability can be improved when the wall is greened.

The planting space filled with the artificial planting base material is light in weight per unit, and is divided into planting spaces by a lattice frame, so that no excessive pressure is applied only to the lower layer. Deformation can be reduced.
In addition, the frame body has a plurality of through holes, and the lattice frame has a large number of through holes, so that relatively uniform air permeability and water permeability can be maintained, and the position of the planting space is limited. The growth conditions can be made uniform without being performed. In addition, the openings in the lattice frame free the plant rooting and promote plant growth. Also, if there is a place where plant growth is bad, only the planting space in this part needs to be replaced, so maintenance work after construction is not troublesome and long-term greening of the wall surface is possible.

Further, since the planting unit shelf is easy to handle as a planting unit, it is possible to partially green the wall surface, and in this case, the decorative effect and the aesthetics can be enhanced. By greening the retaining wall regardless of whether it is fully greened or partially greened, it is possible not only to improve the landscape, but also to avoid environmental degradation due to reflections and burning, etc. It is possible to provide an optimal wall structure regardless of the configuration.

Furthermore, since means for selectively covering at least one of the front and back surfaces of the planting unit shelf with a nonwoven fabric sheet and a net is employed, scattering of plants due to wind damage and drying of the planting space are prevented. In addition, sufficient structural strength as a self-standing wall could be obtained even when constructed only with the planting unit shelves. On the other hand, even with the existing retaining wall greening, construction can be started without the need for reinforcing the retaining wall in advance, and the construction period can be shortened.

Further, since the water supply pipe is selectively provided, it is possible to prevent drying of the artificial planting base material and to provide a suitable planting unit shelf suitable for a planting environment such as a plant to be planted and a construction site. I was able to. The drainage tank discharges excess water that could not be kept inside the planting unit shelves to the outside, so that root rot of the plant can be prevented. It has the effect of water supply.

Furthermore, since the planting space including the artificial planting base material contains a large amount of air, the planting space has a large soundproofing or soundproofing effect, and can be used for measures against noise along with the improvement of the landscape. The effect is enormous, for example.
