Abstract

PROBLEM TO BE SOLVED: To provide a rooftop-greening system for greening the rooftop of a building, making it possible to bank a rooftop using a remarkably small amount used of soil carried on the rooftop, and lighten embankment load or wet load caused by rainfall or the like. SOLUTION: The rooftop-greening system comprises the following process: forming a package body A comprising an appropriate packaging material 1 and a non-water-retentive packaged member composed of appropriate wastes packaged with the packaging material, putting the package body on a place to be greened, banking soil 3 thereon, planting plants such as trees and/or grasses on the banked soil; wherein heavy soil load is not applied on the rooftop of a building.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and a ground material for greening the roof of a building.

[0002]

2. Description of the Related Art Conventionally, in order to green the rooftop of a building, the soil carried into the rooftop is embanked to a predetermined thickness, and plants such as trees and grass are planted.

[0003]

According to the greening method as described above, since the embankment requires soil of a predetermined thickness,
Since the total weight of soil acts on the floor surface of the roof, problems occur in the strength of the floor.

Therefore, if the thickness of the embankment is reduced to reduce the weight in consideration of strength, there is a problem in planting trees (middle trees and high trees). That is, it occurs because it is difficult to secure a stable root system and a stable bearing capacity for trees.

[0005] In particular, there is a risk of falling trees if the trees become too large. Therefore, it is limited to planting small trees and grasses, and the purpose of greening cannot be achieved.

Further, since rainwater associated with rainfall penetrates into the soil and retains water, the wet load is significantly increased. Therefore, the rooftop greening is restricted.

Therefore, the present invention remarkably reduces the soil load of the embankment and the wet load due to rainfall, etc., enables stable growth of trees, and reuses the waste wood. Is to provide wood.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention forms a package with an appropriate packaging material and a packing member such as a waste material that is not water-retainable and is packaged by the packaging material. A rooftop greening system is used, which is characterized by placing the above-mentioned packaging on the rooftop greening place, placing soil on it, and planting plants such as trees and grass on this soil. .

In addition, a net in which the root system of the planted plant is entangled may be laid at a required position of the above-mentioned package.

Further, a packaging body is formed from a suitable packaging material and a suitable packing material such as a waste material which does not retain water and is packed in the packaging material to be used as a ground material.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the accompanying drawings.

In the first embodiment of the present invention, as shown in FIGS. 1 and 2, first, an appropriate wrapping material 1 and a stuffing member 2 for wrapping the wrapping material 1 such as an appropriate waste material having no water retention property. And form a package A.

The packaging material 1 may be a synthetic or natural fiber bag, a net resin bag made of metal wire, or a case made of synthetic resin. If waste is used, the cost is reduced. In addition, it is possible to save resources by considering the avoidance of environmental problems associated with waste treatment.

As the above-mentioned water-retaining filling member 2, styrofoam (sometimes made into a lump of an appropriate size in consideration of filling workability) and an empty plastic bottle (to prevent inflow of rainwater etc.) By putting on a cap, etc., it is possible to solve various environmental problems by reusing waste.

Of course, it is also possible to use an empty bottle or the like, that is, a waste material that does not increase in weight due to water absorption is selected and used, and a waste material other than the waste material that achieves the above object may be used.

The package A prepared as described above is carried into the roof (or the packing member 2 can be packed on the roof), and is spread over the roof B on the greening site.

At that time, since a certain (desired) height is required, the sheets may be stacked. Of course, in the case where a load collapse occurs due to the stacking of the packages A, a reinforcing frame (not shown) for preventing the load collapse may be used.

After that, the soil 3 carried on the package A
Is filled up (sometimes mixed with fertilizer) and the package A is buried.

Then, plants C of trees and grasses (including flowers) are planted on the embanked soil 3.

The tree of the above-mentioned plant C may be appropriately selected such as middle tree, although it depends on the thickness of the embankment.

The space between the packages A may be filled with soil.

In the second embodiment of the present invention, as shown in FIGS. 2 and 3, a net 11 in which the root system of the planting plant C is entangled is laid at a required position of the package A of the first embodiment.

The above net 11 is laid on the topmost package A stacked as shown in FIG. 2 and between the topmost package A and the package A as shown in FIG. There is.

Then, since the root system that has entered the soil 3 is entangled with the net 11 as it grows, there is no danger of falling trees even if the trees become too large. Of course, it can withstand wind pressure.

It should be noted that the net 11 may be determined by appropriately selecting a metal having excellent corrosion resistance.

In the figure, reference numeral 12 is a waterproof layer (such as a sheet).

In the third embodiment of the present invention, the package A of the first embodiment is used as an artificial ground material such as a landfill. Of course, it may be used by stacking it at a desired height.

Then, due to the weight reduction of the artificial ground (since the padding member 2 has no water retention property), a large load such as ground subsidence does not act even if the ground is soft.

[0029]

As described above, according to the rooftop greening system of the present invention, since the amount of soil used for the planting embankment on the rooftop is significantly reduced by using the package, a large soil load is applied to the rooftop floor. It has the advantage of not working.

Further, since a waste material having no water retention property is used for the packing member of the package, the weight is remarkably reduced, the problem due to the wet load is eliminated, and the waste material is reused for reuse. To avoid the occurrence of environmental problems,
You can also look like a high embankment.

Further, since the root system of the tree grown by using the net is entangled, the tree can be stably grown and the fallen tree can be eliminated.

Further, since the packing body filled with the padding member having no water retention property is used as the ground material, the weight of the artificial ground material is remarkably reduced, and the problems such as ground subsidence of soft ground are avoided.
