DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a greening sandbag and a greening sandbag according to the present invention will be described below with reference to FIGS. In this embodiment, a relatively small one is shown.

The bag body 1 of this embodiment is formed in a bag shape by superimposing three or four peripheral edges of a rectangular thin material made of separate members on top and bottom surfaces 11 and 12 of which are overlapped. In addition, as a fixing means of the front ground 11 and the back ground 12, heat welding, adhesive bonding, sewing and the like are selected according to the material of the front ground 11 and the back ground 12.

A part of one short side of the fixed portion 13 of the front surface 11 and the back surface 12 of the bag body 1 forms an opening 2 from which the bonding is released, and connects the inside and outside of the bag body 1 with each other. ing. The opening 2 is for filling the inside of the bag body 1 with a plant growing medium 3 capable of growing the plant P. The inside of the four corners 13 'of the fixed portion 13 is rounded so that the four corners 13' do not protrude when the plant growing medium 3 is filled therein. Accordingly, it is desirable that the four corners of the front surface ground 11 and the back surface ground 13 be cut in a curved shape.

The plant growing medium 3 is prepared by adding, in addition to soil, perlite or a single or mixture of soil substitutes such as powdery, granular, and fibrous soil substitutes such as fibrous cultivation of cedar, beet moss, and semi-carbide of rice husk. You can choose. That is, any material can be freely selected and combined as long as it has suitable water retention, fertilization, water permeability, air permeability and the like for growing plants. The method for producing semi-carbide etc. is described in Japanese Patent Application No. 5-296413 of the present applicant. In addition, the fertilizers, chemicals, and the like necessary for the plant growing medium 3 can be added.

Furthermore, the front surface 11 and the back surface 1 of the bag body 1
In the fixed portion 13 of the second member 2, insertion holes 4 are provided at regular intervals so as to penetrate the front surface ground 11 and the back surface ground 12. The insertion hole 4 is a round hole through which the rope 5 can be inserted. The insertion hole 4 is also provided in the opening 2.

The surface material 11 constituting the bag body 1 is made of a material capable of holding the plant growing medium 3 filled therein. That is, the material is such that the plant growing medium 3 does not flow out or scatter. Further, the surface material 11 is made of a material that has water permeability and allows the seeds S of the plant P mixed in the plant growing medium 3 to penetrate and grow.
That is, the seed S is germinated and formed in the thin film layer with a material that can grow by pushing up the gap between the material structures or breaking through the material structure. Therefore, the surface ground 11 is selected and determined in consideration of the properties of the plant growing medium 3 and the growth environment conditions of the seed S. For example, a porous polyethylene resin film, a polyethylene fiber braided sheet (Dio Net-trade name, Daio Kasei Co., Ltd.) and polyethylene net.

The back surface 12 constituting the bag body is made of a sheet-like material having a strength capable of holding the plant growing medium 3 filled therein, like the above-described front surface material 11. Further, the back surface 12 is made of a material having water impermeability. For example, a polyethylene resin sheet.

Further, a water draining hole 6 can be provided on the back surface 12 constituting the bag body, with the same length position from the fixing portion 13. If there is no drain hole 6, the water will flow out from the height H of the turn 15 of the surface ground 11.

According to this embodiment, after filling the inside of the bag body 1 with the plant growing medium 3, the rope 5 is inserted into the insertion hole 4 in a sewing manner as shown in FIG. 13
Is provided on the surface ground 11 side, and the rope 5 is tightened. The tightening by the rope 5 squeezes the bag body 1 to pressurize the plant growing medium 3, and the bag body 1, the plant growing medium 3
Into a fixed shape. In addition, the tightening by the rope 5 simultaneously closes the opening 2.

The insertion of the rope 5 into the insertion hole 4 can be made to cross the surface ground 11 as shown in FIG. According to the insertion of the cross-shaped rope 5, the pressurization of the squeezed plant growing medium 3 of the bag body 1 can be strengthened.

Then, as shown in FIG. 2, the seeds S of the plant P are embedded in the plant growing medium 3 by breaking or penetrating the surface ground 11 from outside the surface ground 11. The seeds S can be freely selected from grasses such as bermudagrass and buffalograss, grasses such as Tifton, flowers such as poppy, gazania, and daisy, trees, and the like according to the installation location.

As shown in FIG. 3, the seeds S of the plant P are fixed to the sheet 7 and the sheet 7 is inserted into the bag body 1 when the plant growing material 3 is filled in the bag body 1. You can also do so.

Thereafter, the bag body 1 is installed at a predetermined location with the front surface 11 up and the back surface 12 down, but there is no particular limitation on the installation location. For example, as shown in FIG. 6, it is installed in place of a groove cover above the U-shaped groove 8, or as shown in FIG. be able to. Further, it is not always necessary to set the front ground 11 upward and the back ground 12 downward, but it is also possible to install the front ground 11 and the back ground 12 on an inclined surface or the like. As shown in FIG. 5, it is fitted between the inclined blocks and installed such that the surface ground 11 is the upper surface. When a plurality of units are installed adjacent to each other, the units can be connected using the insertion holes 4 and the ropes 5.

In the installed state, when it rains, rainwater passes through the top surface 11 of the bag body 1 and is absorbed by the plant growing medium 3, and reaches the height h of the drain hole 7 in the back surface 12 or the top surface. Water is stored up to the height H of the turn 15 of the ground 11. For example,
When the sandbag thickness is about 15cm, the above height is about 7.5c
m. Assuming about 10% of the soil to about 70 percent and the top 7.5cm of which the available water, so the height of about 6cm component, becomes able to retain moisture of approximately 60l in 1 m ^2, per the This is a considerable amount of about 40 cm deep in the ground.

When the rainwater absorbed and stored in the plant growing medium 3 exceeds the above height h or H, the rainwater is discharged from the drain hole 7 or the surface ground 11 to the outside of the bag body 1, and the plant growing medium 3 becomes The ground 11 is shielded from light and blocked by wind to prevent unnecessary evaporation. In particular, rainwater is effectively stored without waste by turning back the fixed portion 13. Therefore, the moisture of the plant growing medium 3 is held in a large amount for the sandbag thickness, and is not easily dried. Further, root rot and withering of the plant P are prevented, and the plant P grows reliably. That is, complicated watering becomes unnecessary, and management becomes easy.

Furthermore, in the installed state, the plant growing medium 3 is partially covered with the surface ground 11, so that the growth of weeds is prevented. Therefore, complicated weeding becomes unnecessary, and management becomes easy.

Furthermore, in the installed state, the plant growing medium 3 does not flow from the bag body 1, so that the surroundings are not stained even when used as a heat insulating material on a rooftop, a wall surface or the like. In addition, the lower gap between the bag bodies can be used as a drainage channel as it is, eliminating the need to form a drainage layer and fill the ground in advance when greening non-soil land such as concrete or rock as in the past. Was.

Further, in the state used as a sandbag, since the plant P grows from the surface ground 11, the appearance is good even when used for a long time. In addition, the insertion hole, the rope 5
The stacking strength of the sandbags can be enhanced by connecting the individual pieces or connecting the auxiliary members by using the method.

FIG. 8 shows a second embodiment of the greenery sandbag according to the present invention.
It shows an embodiment.

In this embodiment, the bag body 1 filled with the plant growing medium 3 has a cylindrical shape. Also,
A removal unit 10 that is surrounded by perforations and that can be cut off is provided on a part of the surface ground 11.

According to this embodiment, it is suitable for a greening structure installed in a spot manner. When the removing unit 10 is removed, a large plant P such as a tree can be directly planted.

FIG. 9 shows a third embodiment of the sandbag for greening according to the present invention.
It shows an embodiment.

In this embodiment, when filling the bag main body 1 with the plant growth medium 3, a box-shaped frame 20 formed into a box shape with rock wool or the like is used.

According to this embodiment, the shape does not collapse during use.

FIG. 10 shows a fourth embodiment of a sandbag for greening according to the present invention.

In this embodiment, the surface material 11 has a double sheet shape in which the upper surface of a thin material is covered with a mesh 16.
This shows an improved soil sealing force. As the mesh 16, for example, the product name “Dionet” of Dio Kasei Co.
Can be selected, and the light transmittance can be changed according to the mesh size. The seed is sown by breaking the thin material from the gap 17 between the meshes 16 and germinating from the gap 17. Therefore, it is suitable for sealing soil containing fine particles.

Although not shown, when the surface layer 11 of the bag body 1 is constituted by two layers, a material which is deteriorated by contact with an acidic or alkaline liquid can be selected as the second layer below the surface layer of the mesh. . For example, 0.1N NaOH is applied to the surface of about 0.002 ml / cm ^2.
If sprayed on the desired portion of the first portion and dried, the plant growing medium 3 does not flow out during transportation or the like because of strength during drying, but becomes extremely weak and deteriorates when water is applied after installation. Therefore, there is no problem because the surface ground 11 is broken at the time of budding. For example, as the second layer of the surface layer 11, it is possible to select, for example, "Oken R-40" (trade name of Oji Building Materials Co., Ltd.), which is a rough paper. In this case, when the bag main body 1 is moved in a state where the seeds are mixed, it is possible to prevent the seeds from being displaced from the broken or penetrated surface and the foliage from becoming difficult to grow.

As described above, in addition to the illustrated embodiment, it is also possible to provide an embodiment in which the front surface 11 and the back surface 12 of the bag body 1 have a multi-layer structure or are provided with reinforcing materials to increase the size. In addition, a pulp-based nonwoven fabric can also be used as the surface material 11, and it has been confirmed that, for example, budding is promoted under the brand name “Kinocross” of Honshu Paper Co., Ltd.

[0045]

As described above, in the sandbag for greening according to the present invention, it is possible to grow plants from the material of the front surface and the back surface of the bag body, and to fill the inside of the bag body. Since a plant growing medium as soil and the like already exists, it can be used as a greening structure.

Common to each claim is that there is no need for complicated watering and weeding, so that there is an effect that the management when used as a greening structure is easy.

Further, since the plant growing medium does not flow out, the invention can be used as a heat insulator for rooftops, walls and the like. In addition, concrete,
Greening can be achieved not only by installing it on asphalt, bedrock, etc., but also by placing it in a gap such as a concrete block.

As a common claim, it is possible to plant a seedling or cut and bud.

Furthermore, in the case where the plant is used as a greening structure, rainwater and the like can be prevented from flowing out by storing rainwater and the like at the turn of the fixing portion, and the rainwater and the like can be surely absorbed by the plant growing medium. This has the effect of making the management easier.

Furthermore, there is the effect that the shape retaining shape of each individual can be strengthened or the connection of each individual can be strengthened by using the insertion hole, the rope and the like. ,

Further, in the present invention, since the medium for plant growth and / or the seeds are mixed in the bag body,
Greening can be performed only for sandbag installation work and water supply work.
