Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wall greening panel and a method for forming a greening base using the wall greening panel.
[0002]
[Prior art]
Conventionally, as this type of wall greening panel, for example, one shown in FIG. 5 is known (Japanese Patent Laid-Open No. 9-9787). This wall greening panel has a rectangular frame made of H-shaped steel in contact with a wall (not shown), and a plurality of steel support girders 31 having a plurality of water passage holes on the upper and lower surfaces. A plurality of rectangular parallelepiped planting containers 32, 32,... Are accommodated in each support girder 31 in a horizontal manner.
[0003]
The planting container 32 is divided into three stages by a horizontal plate having a water passage hole, and has a water passage 33a on the upper surface, both side surfaces, and the lower surface, respectively, and a box 33 having a water receiving surface on the upper surface. It is covered with a split lid 34, 34 having three planting holes 34a and a plurality of vent holes 34b around them.
[0004]
In the planting container 32 having the above-described structure, soil is filled in the interior partitioned into three stages, and a plant for greening is planted in the soil. Then, a plurality of planting containers 32, 32... In which the soil is filled and plants are planted are arranged on the support girder 31 and passed through a plurality of water supply holes 31a on the upper surface of the uppermost support girder 31. The supplied water is made to flow down sequentially to the lower planting containers through the water holes, and the plants are grown by supplying water to the planting containers 32, 32. In this way, a greening base is formed.
[0005]
[Problems to be solved by the invention]
However, since the conventional wall greening panel is filled with soil in each of the plurality of planting containers 32, 32... And planted for planting, a greening base is provided. There is a problem that it takes time to form.
[0006]
Moreover, since the soil is filled in the plurality of planting containers 32, 32... And water is supplied to the soil by flowing down water from the uppermost planting container, the soil has a small water holding capacity. Since the water tends to flow down, the soil becomes deficient due to water shortage, the soil is washed away with the flowing water, or the wall surface below the frame that supports the planting containers 32, 32. There is a problem of soiling with water and soil. Such a problem is conspicuous when a wall greening panel is provided on a vertical wall surface such as a building outer wall or a highway side wall.
[0007]
Therefore, an object of the present invention is to provide a wall greening panel that can easily form a greening base, does not cause soiling due to irrigation of the wall on which the greening base is formed, and can form a greening base on a vertical wall and has a large water retention capacity. There is to do.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the wall greening panel of the invention of claim 1 is:
A water retaining mat installed on the wall ;
An irrigation pipe that is disposed between the back surface of the water retention mat and the wall surface and is not exposed on the surface side of the water retention mat, and supplies water to the water retention mat;
It is arrange | positioned on the surface of the said water retention mat | matte, and is equipped with the soil holding material by which the soil for greening is sprayed.
[0009]
According to the first aspect of the present invention, the wall surface greening panel is composed of the water retention mat, the irrigation pipe, and the soil retaining material, and has no soil for greening and is relatively lightweight, so it can be easily attached to the wall surface. It is done. Thereafter, by simply spraying the soil for greening onto the wall surface greening panel and causing the soil holding material to hold the soil for greening, a large area greening base is formed at a time. Therefore, since it is not necessary to arrange the planting container on the support beam after each of the plurality of planting containers is filled with soil, a greening base is easily formed.
[0010]
Further, since the irrigation pipe is disposed between the back surface and the wall surface of the water retention mat and is not exposed to the surface side of the water retention mat, the soil sprayed on the soil retaining material is applied to the irrigation pipe. It does not enter the irrigation pipe from the provided water supply hole or adhere to the water supply hole to narrow the opening of the water supply hole. Therefore, the greening base is easily formed by spraying the soil for greening, and there is no problem such as clogging of the irrigation pipe, and water is stably supplied.
[0011]
Here, the position where the irrigation pipe is not exposed to the surface side of the water retention mat means that when soil is sprayed on the soil holding material, the soil enters from the water supply hole of the irrigation pipe or the opening of the water supply hole of the irrigation pipe is A position that is not narrowed by the soil.
[0012]
Moreover, in the greening base formed by spraying soil on the wall greening panel, when water is supplied from the irrigation pipe, this water is first stored in the water retaining mat. Next, water is supplied to the water retaining mat, and the water gradually infiltrates through the water retaining mat into the soil retaining material disposed on the surface of the water retaining mat and sprayed with the greening soil to a predetermined thickness. . That is, water is always stored in the water retaining mat, and the stored water is gradually supplied to the greening soil held by the soil retaining material via the water retaining mat. As a result, water is gradually and uniformly supplied to the greening soil, so that even when the water retention capacity of the soil is small, the soil portion is dried or supplied from the irrigation pipe as in the past. It is difficult for the drained water to flow down from the greening base through the gaps in the soil, or the soil to flow with the flowing water. Therefore, the plant generated in the greening soil does not wither, the soil flows out and decreases, and the wall on which the greening panel is arranged is not soiled with muddy water.
[0013]
The wall surface greening panel of the invention of claim 2
In the wall surface greening panel according to claim 1,
A presser net for pressing the soil retaining material against the water retaining mat is provided.
[0014]
According to the invention of claim 2, since the soil retaining material is pressed against the water retaining mat side by the net, the soil retained by the soil retaining material falls off or flows out from the wall greening panel. hard. Therefore, according to the wall surface greening panel, the greening base can be easily formed, and the wall surface is greened stably.
[0015]
The wall surface greening panel of the invention of claim 3 is:
In the wall surface greening panel according to claim 1 or 2,
An impermeable film is disposed between the wall surface and the water retaining mat.
[0016]
According to invention of Claim 3, since the impermeable film was arrange | positioned between the said wall surface and the said water retention mat , from the fertilizer contained in the soil which the said soil retention material hold | maintains, and the plant grown in the said soil The secretory product does not reach the wall where the wall greening panel is installed. Therefore, erosion and deterioration of the wall surface are prevented.
[0017]
The method for forming the greening base of the invention of claim 4
A step of placing a green wall panel according to the wall in any one of claims 1 to 3,
And spraying soil for greening toward the soil retaining material in the wall surface greening panel installed on the wall surface .
[0018]
According to the invention of claim 4, the green wall panel installed on the wall, toward the soil holding material in the green wall panel, for example, only blowing soil consisting of plant seed and leaf mold, the greening foundation It is formed. That is, since not include the soil is placed a lightweight green wall panel to the wall, the work of the installation is easy. And the greening base | substrate of a large area is easily formed at once by only spraying the soil for greening toward the said soil holding material. Therefore, a greening base can be formed much more easily than filling a plurality of planting containers as in the past and planting the plant in the planting container filled with the soil and placing the plant on the support beam. As a result, the number of processes and the construction period for forming the greening base are shortened, so that the construction cost of the greening base is reduced.
[0019]
In addition, since the installation of the wall greening panel and the arrangement of the soil are performed in different processes, for example, the type of soil is changed corresponding to the arrangement environment of the greening base, or plant seeds and fertilizer are mixed as the soil. Can be used. That is, by changing the soil to be sprayed, many types of greening bases can be formed using one kind of wall surface greening panel, and the degree of freedom in forming the greening bases is increased.
[0020]
Moreover, even if the soil of the greening base is lost, the greening base can be easily repaired by spraying the soil on the defective part.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.
[0022]
Fig.1 (a) is a top view which shows one Embodiment of a wall surface greening panel. This wall greening panel is provided on a concrete wall W whose surface extends substantially vertically. FIG. 1B is an enlarged plan view of the region A shown in FIG. 1A, and FIG. 2 is a longitudinal sectional view in FIG.
[0023]
This wall greening panel has the irrigation pipes 2, 2, 2 attached to the surface of the concrete wall W in a substantially horizontal direction, and a hose 3 that guides water to the irrigation pipes 2, 2, 2, An irrigation device 5 for supplying water to the irrigation tubes 2, 2, 2 is provided. Note that three irrigation pipes 2, 2, and 2 are attached to the surface of the concrete wall W in the horizontal direction, but one, two, or four or more irrigation pipes are attached according to the amount of water to be supplied. May be. The irrigation device 5 can set the amount and time of water supplied to the irrigation pipes 2, 2, and 2 according to the season and the plants planted on the wall greening panel. As shown in FIGS. 1B and 2, the irrigation pipe 2 has a plurality of drip holes 2a, 2a... For discharging the guided water.
[0024]
A water retaining mat 7 is arranged at a position where the concrete wall W should be greened so as to cover the irrigation pipes 2, 2, 2. A non-woven holding mat 8 as a soil holding material is disposed on the surface of the water holding mat 7. This non-woven holding mat is formed in a predetermined thickness by loosely and irregularly entwining a linear body made of nylon in the shape of a loofah fiber and having a larger gap than the loofah fiber. is doing. The voids of the non-woven holding mat 8 are formed in a size that allows the soil to be blown into the position where the soil is properly held by the non-woven holding mat 8. A lath net 10 as a presser net is disposed on the surface of the non-woven holding mat 8, and this lath net 10 is fixed to the other end of an anchor bolt 11 embedded in the concrete wall W. . The non-woven holding mat 8 is pressed against the water holding mat 7 by the lath net 10.
[0025]
Here, the irrigation pipe 2 may be sandwiched between the concrete wall W and the water retaining mat 7, or may be encased in the water retaining mat 7, or a part of the irrigation pipe 2 may be placed on the concrete wall W side from the water retaining mat 7. It may be exposed. In short, the soil sprayed onto the nonwoven holding mat 8 enters the irrigation pipe 2 from the drip hole 2a provided in the irrigation pipe 2, or adheres to the drip hole 2a to narrow the opening of the drip hole 2a. It only has to be designed so that it does not occur. Further, the water from the irrigation pipe 2 is not directly supplied to the non-woven holding mat 8 side, but first supplied to and stored in the water holding mat 7 and then infiltrates the non-woven holding mat 8 side. Just do it.
[0026]
A greening base is formed on the wall greening panel having the above configuration as follows. That is, the soil 13 made of plant seeds and humus is sprayed onto the nonwoven holding mat 8 on the surface of the wall greening panel disposed on the concrete wall W as shown in FIG. 3 using compressed air or the like. . As a result, the soil 13 enters into the gap between the nylon linear bodies of the nonwoven fabric holding mat 8 that are relatively loosely entangled and adheres to the nylon linear bodies. As a result, the soil 13 is effectively fixed to the non-woven holding mat 8 even though the wall greening panel is arranged on the substantially vertical concrete wall W. In this way, a greening base is formed on the wall surface greening panel arranged on the concrete wall W. Note that a thickener or an adhesive may be included in the soil 13 so as to be firmly fixed to the non-woven holding mat 8. The soil 13 may contain fertilizer or may not contain seeds.
[0027]
The wall greening panel on which the greening base is formed as described above operates as follows. When the time set in advance in the irrigation device 5 is reached, a predetermined amount of water set in advance is supplied to the irrigation pipes 2, 2, 2 via the hose 3. The amount of water is determined based on the location of the greening base and the amount of water evaporated according to the season, the water retention capacity of the water retention mat, the amount of water required according to the type of plant, and the like. The water guided to the irrigation pipes 2, 2, 2 is discharged from a plurality of drip holes 2 a, 2 a. This water spreads substantially uniformly over substantially the entire water retaining mat 7 and is stored in the water retaining mat 7. The water stored in the water retaining mat 7 is absorbed by the soil 13 held in the nonwoven holding mat 8, that is, the greening base. As a result, the seeds of the soil 13 germinate and grow, and as shown in FIG. 4, plants 15 such as lawns are generated on the greening base.
[0028]
In this way, the greening base using the wall greening panel stores water in the water retaining mat 7 via the irrigation pipe 2 and gradually stores the stored water in the soil 13 held by the nonwoven holding mat 8. Since it is supplied, water can be gradually and gradually supplied to the soil 13 despite being installed on the surface of the substantially vertical concrete wall W. Therefore, even if the water retention capacity of the soil 13 is small, the soil portion does not dry as in the past, or the water supplied from the irrigation pipe does not flow down from the greening base, or the soil does not flow along with the flowing down water. . Therefore, the plant 15 of the soil 13 can be grown without dying, the soil 13 can be held without draining, and the beauty of the wall on which the greening base is formed can be maintained. Further, since the water supplied to the water retention mat 7 is adjusted to a predetermined amount by the irrigation device 5, it corresponds to the water retention capacity of the water retention mat 7 and the environment where the greening base is formed. In addition, it is possible to effectively prevent the drying of the soil 13 and the outflow of water from the greening base.
[0029]
Moreover, when the said wall greening panel is attached to the said concrete wall W, since it does not contain the soil 13 and is comparatively lightweight, it is easily attached to the said wall W. Thereafter, the greening base can be easily formed at a time only by spraying and holding the soil 13 on the non-woven holding mat 8. Therefore, since the greening base can be formed more easily than before, the number of processes and the construction period for forming the greening base can be shortened, and the construction cost of the greening base can be reduced.
[0030]
Further, since the irrigation pipe 2 is covered with the water retention mat 7 and is disposed at a position not exposed to the surface side of the water retention mat 7, the soil 13 sprayed on the nonwoven holding mat 8 is used as the irrigation pipe 2. It does not enter the irrigation pipe 2 from the drip hole 2a provided in the throat or adhere to the drip hole 2a and narrow the opening of the drip hole 2a. Therefore, the irrigation pipe 2 can be stably supplied with water to the greening base without problems such as clogging.
[0031]
In addition, since the installation of the wall greening panel and the spraying of the soil 13 are performed in different processes, many types of greening bases can be formed using one type of wall greening panel. Can be formed.
[0032]
In addition, even if the soil of the greening base is lost, the greening base can be easily repaired only by spraying the soil on the defective portion.
[0033]
In the embodiment, an impermeable film may be disposed between the concrete wall W and the water retaining mat 7. This impermeable film blocks water from the water retaining mat 7 side to the concrete wall W, and the concrete wall W can be prevented from being eroded or deteriorated by the fertilizer or the secretions from the plant contained in the soil 13. .
[0034]
In addition, the irrigation pipe 2 is directly attached to the surface of the concrete wall W, and the water retention mat 7 is disposed so as to cover the irrigation pipe 2. However, if the irrigation pipe 2 can supply water to the water retention mat 7, You may arrange | position between the water retention mat | matte 7 and the nonwoven fabric retention mat 8, or you may incorporate in the water retention mat | matte 7. At this time, it is important to arrange the irrigation pipe 2 at a position where it is not exposed on the surface side of the nonwoven fabric holding mat 8. This prevents clogging of the drip hole 2 a of the irrigation pipe 2 by the soil 13 and intrusion of the soil 13 into the irrigation pipe 2 when the soil 13 is sprayed onto the nonwoven holding mat 8. In addition, the water from the irrigation pipe 2 can be supplied to the soil 13 uniformly and gradually through the water retention mat 7 after being temporarily stored in the water retention mat 7 without being directly supplied to the soil 13.
[0035]
Moreover, in the said embodiment, although the nonwoven fabric holding mat 8 which consists of a nylon linear body was used as a soil holding material, the mat-shaped thing which entangled the fiber which consists of a metal material, a wire, etc., or resin, metal which has an unevenness | corrugation, Other materials that have a function of holding soil and formed by, for example, may be used. When a material made of a metal material is used as the soil retaining material, it is necessary to select a material that is not easily corroded by water, fertilizer contained in the soil, or plant secretions, and to perform rust prevention and anticorrosion processing.
[0036]
Moreover, the soil 13 made of plant seeds and humus was sprayed on the nonwoven holding mat 8, but the soil made only of humus was sprayed on the nonwoven holding mat 8, and thereafter seeds and seedlings were separately seeded. You may plant in the said soil.
[0037]
Moreover, in the said embodiment, although one wall surface greening panel was installed in the concrete wall W and the soil 13 was sprayed on this wall surface greening panel, after installing several wall surface greening panels in a concrete wall, these several A large area greening base may be formed by spraying soil onto the wall greening panel at once. This makes it possible to efficiently form a large area greening base.
[0038]
Moreover, in the said embodiment, after arrange | positioning the irrigation pipe | tube 2 on the surface of the concrete wall W, the water retention mat 7 and the non-woven retention mat | matte 8 were each arrange | positioned and the wall surface greening panel was formed, After assembling the mat 7 and the non-woven holding mat 8 to form a wall greening panel, the wall greening panel may be attached to the concrete wall W. Of course, there may be a plurality of the wall greening panels assembled in advance.
[0039]
Further, after attaching the water retention mat 7 and the non-woven retention mat 8 to the concrete wall W, the irrigation pipe 2 may be attached at a position where it is not exposed to the surface side of the water retention mat 7.
[0040]
In addition, the water retaining mat 7 and the nonwoven retaining mat 8 are fixed to the concrete wall W by the lath net 10 and the anchor bolt 11, but a net other than the lath net 10 may be used. Fixing means may be used.
[0041]
Moreover, although the said wall surface greening panel was arrange | positioned on the surface of the substantially vertical concrete wall W, you may arrange | position to the wall surface which has a predetermined angle. Moreover, you may install in resin panels other than a concrete wall surface.
[0042]
【The invention's effect】
As apparent from the above, according to the wall surface greening panel of the invention of claim 1, the water retaining mat, the irrigation pipe for supplying water to the water retaining mat, and the soil retaining material disposed on the surface of the water retaining mat. Therefore, it is easy to attach a relatively light wall greening panel to the wall, and spray the soil for greening on the wall greening panel so that the soil retaining material holds the greening soil at once. Since the greening base of the area can be formed, the greening base can be formed more easily than before.
[0043]
Further, since the irrigation pipe is arranged at a position not exposed on the surface side of the water retention mat, the soil sprayed on the soil retaining material enters the irrigation pipe from the water supply hole provided in the irrigation pipe, or Since it is possible to prevent the opening of the water supply hole from being narrowed by adhering to the water supply hole, it is possible to easily form a greening base by spraying the soil for greening on the wall greening panel, and clogging of the irrigation pipe due to the spraying of soil The wall greening panel that can stably supply water to the soil can be achieved.
[0044]
Further, since the irrigation pipe is disposed between the back surface and the wall surface of the water retention mat and is not exposed to the surface side of the water retention mat, water is always stored in the water retention mat by the irrigation pipe. The stored water can be gradually and uniformly supplied to the soil of the soil holding material. Therefore, it is possible to prevent the soil portion from drying, or the water supplied from the irrigation pipe from flowing down from the greening base through the gap between the soils, or from flowing along with the flowing water. As a result, it is possible to prevent plant dying generated in the soil, reduction of the soil, and contamination of the wall surface on which the greening panel is arranged.
[0045]
According to the wall surface greening panel of the invention of claim 2, since the presser net for pressing the soil holding material against the water retaining mat is provided, the soil held by the soil holding material falls off the wall greening panel. Since it can be prevented from flowing out, a greening base can be easily formed, and the wall surface can be greened stably.
[0046]
According to the wall surface greening panel of the invention of claim 3, since a water-impermeable film is disposed between the wall surface and the water retaining mat , the fertilizer contained in the soil held by the soil retaining material or grown in the soil is such secretions from plants is, because it prevents Rukoto to reach the wall this wall greening panel is installed, can be prevented erosion and deterioration of the wall.
[0047]
Method of forming a greening base of the invention of claim 4 includes the step of installing the wall surface of the green wall panel according to any one of claims 1 to 3, the in the installed above green wall panels to the wall surface since a step of blowing the soil towards the soil holding member, because a lightweight green wall panel may be installed on a wall surface not include soil, it can be easily installation work of green wall panel, moreover, the soil A large area greening base can be easily formed at a time simply by spraying on the soil retaining material. As a result, since the greening base can be formed much more easily than before, the number of steps and the construction period for forming the greening base can be shortened, and the construction cost of the greening base can be reduced.
[0048]
In addition, since the installation of wall greening panels and the placement of soil are performed in different processes, many types of greening bases can be formed using one type of wall greening panel, thus forming a greening base with a high degree of freedom. can do.
[0049]
In addition, even if the soil of the greening base is lost, the greening base can be easily repaired only by spraying the soil on the defective part.
