Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a simple artificial ground for planting, which is mainly provided on the roof of a building.

BACKGROUND OF THE INVENTION In recent years, greening has been promoted as part of environmental improvement in cities, and rooftop gardens and brocades with trees have been installed on the roofs of buildings and other structures. Such artificial ground includes, for example, a rooftop made of concrete or the like, filled with lightweight soil material to which lightweight aggregates such as perlite and vermiculite are appropriately added. By the way, it is better for such artificial ground for planting to have less load on the structure of the building.

Therefore, in the past, the layer of lightweight soil material was made as thin as possible to reduce the load on the building.

Problems to be Solved by the Invention However, in the conventional artificial ground as described above, the soil is soft and lacks support strength for trees, and even when reinforced with splints, even the splints become unstable. The problem was that the trees could not be adequately supported. In particular, in the case of tall trees that are taller than the height of a human, the soil cannot be thickened or the soil is soft, so they lack the ability to take root, and if shaken by strong winds, they may not take root. The problem was that they would wither and sometimes fall down.

In view of these problems, the present invention aims to provide a simple artificial ground for planting on which even tall trees can be planted.

Means for Solving the Problems A configuration for achieving the above object will be explained using FIGS. 1 to 6, which correspond to an embodiment of the present invention.

In the present invention, a space (4) is formed between the structures (3), and a net-like support member (5) provided with a nonwoven fiber molded material (9) on one side is placed in the space (4). They are arranged at vertical intervals and attached to the structures (3) (3). Moreover, the space (4) is filled with soil material.

Effect By having the above-mentioned configuration, the net-like support member (5
Moisture tends to adhere to the non-woven fiber molded material (9) provided in the non-woven fiber molded material (9), which promotes the development of the fine roots of the tree, and the fine roots take root in the non-woven fiber molded material (9), and the net-like support member ( 5)
The trees will be reliably supported through the

Example Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Fig. 2, (1) shows an elevated walkway that constitutes the building according to the present invention, and the basic structure of this elevated walkway (1) is a steel frame erected on a foundation (not shown) provided below. A structure (3) such as a truss beam is supported by the supporting legs (2) (2).

In this embodiment, as shown in FIG. 3, two mesh support members (5) (5) are placed vertically apart in the space (4) between the structures (3) (3) arranged in parallel. They are arranged horizontally, separated by

As this net-like support member (5), one as shown in FIG. 4 is used. In other words, the rectangular support frame (6) has a net body (7) made of a hexagonal weave of slightly thick net material (7).
8) is fixed. As this netting material (7), it is desirable to use a material that does not change in quality due to moisture and has high mechanical properties, especially tensile strength.Specifically, such a material includes nylon, etc. So-called synthetic resin fibers can be considered. Note that the net body (8) may be made by knitting the above-mentioned net material (7) into a base shape.

A non-woven fiber molded material (9) is provided on one side of the net main body (8) so as to close the gaps in the net main body (8).

The nonwoven fiber molded material (9) is integrally fixed to the netting material (7), as shown in FIG. The nonwoven fiber molding material (9) includes nylon, which is a material that does not lose its shape due to moisture and has water permeability, water retention, and strength.
It is desirable to use a nonwoven fabric made of Tetron, polyester, or the like.

In addition, inside the nonwoven fiber molded material (9), a irrigation pipe (
10) (10) are stretched horizontally and vertically so that liquid such as water can be released into the nonwoven fiber molded material (9).

In this example, a net-like support member (
5), the support frame (6) is removably fastened to the structure (3) (3) by appropriate means.

Further, the space (4) is filled with lightweight soil material as shown in FIG. This lightweight soil material has
As in the past, lightweight materials such as vermiculite, perlite, or peat moss may be added to field soil, or they may be artificially mixed with artificial lightweight aggregates with appropriate properties without using field soil at all. But that's fine. In addition, on the drawing,
Although not particularly differentiated, the composition of the lightweight soil material is divided into the upper and lower net-like support members (5) (5), the intermediate support layer (11) in the middle part, the lower drainage layer (12), and the upper part. The topsoil layer (13) may be slightly changed. In that case, the intermediate support layer (11) is the basic structure, and the drainage layer (12) is made of a material with excellent drainage properties. On the other hand, for the topsoil layer (13), it is preferable to use a material that is difficult to be blown away by wind.

In the figure, (14) is a lightweight soil material and a structure (3) (
3), and (15) is a drainage channel (15) that is continuous with the lower end of the boundary wall (13) and is installed at the lowest part

), the water flows out onto the water collection bottom wall (15), passes through the water collection bottom wall (15), and is collected in the drainage channel (16). In addition, the water collected in the drainage channel (16) may be looped around the irrigation pipe (lO).

Further, below the water collection bottom wall (15), a structure (3
)(3) A bottom plate (17) extending over the bottom is provided.

In addition, during actual construction, the lower mesh support member (5
) Before installing, fill the water collection bottom wall (15) with lightweight soil material to form a drainage layer (12), then install the lower mesh support member (5), and then install the middle part. Fill with lightweight soil material again and install intermediate support 1'ii (11)
form. Then, on the intermediate support layer (11) thus formed, the upper net-like support member (5) is attached, and finally the topsoil layer (13) is formed. In that case, when transplanting a seedling that has grown to a certain extent, the non-woven fiber molded material (9) provided on the upper mesh support member (5),
A hole (18) is pre-drilled as shown by the two-dot chain line in Fig. 4, and after inserting the main root part of the seedling into the hole (18), the upper net-like support member (5) is attached to the structure ( 3) It is preferable to fix the seeds in (3). In addition, when growing from seeds, the seeds are scattered on the topsoil layer (13).

Next, FIG. 6 shows a state in which the plants of the present invention are planted on the artificial ground. That is, the taproot (20) of the tree (19) is

It especially develops near the non-woven fiber molded materials (9) (9) and becomes intertwined with the fibers constituting these non-woven fiber molded materials (9) (9). Therefore, the trees (19) are supported not only by the soil parts such as the intermediate support layer (11), but also by the non-woven fiber molded material (9), which is supported by the above-mentioned structures (3) (3). It will also be supported by support members (5) (5).

In this case, if drop irrigation is performed through the irrigation pipe (10), the nonwoven fiber molded material (9) will always be in a moderately moist state, so that the fine roots (22) (

), the fine roots (22) (22)... will take root even better, and the tree (19) will be supported more reliably. Further, from the irrigation pipe (10), it is possible to supply liquid fertilizer, which tends to be in short supply in this type of artificial ground, and to inject a pesticide solution for preventing insect damage.

Effects of the Invention As described above, in the present invention, a space is formed between structures, a net-like support member supported by the above structure is disposed in the space, and soil material is placed in the space. By filling the ground and creating an artificial ground for planting, there is not much load on the structure, so it can be used for greenery even on elevated roads and elevated walkways, which have a structurally limited load bearing unlike buildings. zones can be formed. Moreover,
By providing the net-like support member with a non-woven fiber molded material such as a non-woven fabric that has excellent water retention and water permeability, moisture adheres to the non-woven fiber molded material, increasing water retention and promoting root development. This has the effect of making it easier for trees to take root. Moreover, the roots become entwined with the non-woven fiber molded material, and the whole tree is supported not only by the soil part but also by the net-like support member via the non-woven fiber molded material, providing sufficient support even against strong winds. It has the advantage of being possible.

In addition, as in this example, if the irrigation pipe is arranged in the nonwoven fiber molded material provided in the net-like support member, the nonwoven fiber molded material can be used as an irrigation passage, and the water supply and It has the advantage that fertilization and pest control can be carried out in a timely manner, making maintenance management easier.
