ABSTRACT:
BACKGROUND OF THE INVENTION
a) Field of the Invention
This invention relates to a plant cultivation mat (or grass growing mat) to be laid on the roof top, veranda, terrace, etc. of buildings (in particular, an artificial ground) for growing various plants such as, especially, ground-covering plants like lawn, etc., grasses, flowers, vegetables, and so forth, and to a method for laying such plant cultivation mat.
b) Description of Prior Arts
It has been the conventional practice that, when cultivating or growing plants at a location having flat laying surface such as the roof top, veranda, terrace, etc. of buildings, a water-prevention layer and a root-protecting layer is formed, or a sheet is further laid thereover, and then soil is spread over the sheet to cultivate ground-covering plants such as lawn, grasses and shrubs, vegitables, and so forth (vide: for example, laid-open gazette of Japanese Patent Application No. 4-99411).
With the abovementioned method of spreading soil, however, there arises necessity for providing outfits such as water-prevention layer, etc., which give rise to various problems such that the equipment can hardly be adopted in those existing buildings, while cost to be borne would increase when it is adopted in new buildings.
Furthermore, a large-scaled working becomes necessary for utilization of the abovementioned plant cultivating facility, which requires enormous amount of time and labor.
On the other hand, the life of the water prevention layer is, in general, said to last from ten to fifteen years, which would require removal for replacement of the layer at every time its service life is ended. Besides its service life, when there occur unexpected damages to the water-prevention layer and the laying surface of the plant cultivation mat during the plant cultivation work, it becomes also necessary to remove the plants under cultivation and the soils for cultivation with a view to repairing such water prevention layer from leaking. Again, enormous amount of time and labor are needed for this removing work.
SUMMARY OF THE INVENTION
The present invention has been made in view of the afore-described points of problem, and aims at providing the plant cultivation mat which can be adopted in those existing buildings, and does not require a great deal of time, labor, and cost for its laying and removing and the method for laying such plant cultivation mat, as well.
A further object of the present invention is to provide the plant cultivation mat and the method for its laying, which is easier for controlling the soil and the water.
According to the present invention, in one aspect thereof, there is provided a plant cultivation mat, which comprises one or a plurality of cells with water-passage ports being perforated in the vicinity of the bottom part thereof, said one or a plurality of cells constituting a mat frame disposed in a depressed form to permit the top part thereof to open, and an inwardly recessed part being formed at the lower part of the requisite side wall of the cell.
According to the present invention, in another aspect thereof, there is provided a method for laying a plant cultivation mat, which comprises laying said plant cultivation mat on the laying surface in a manner to define a space having a required route within an inwardly recessed part of the cell.
According to the present invention, in still another aspect thereof, there is provided a method for laying the plant cultivation mat, which comprises: providing, in advance of laying the plant cultivation mat, a water-holding layer on the mat laying surface.
According to further object of the present invention, there is provided a method for laying plant cultivation mat, which comprises, at the time of laying the plant cultivation mat on the mat laying surface, defining a space having a required route, and simultaneously disposing water-supply pipe in any arbitrary route in this space.
The foregoing objects, other objects as well as the specific construction and function of the present invention will become more apparent and understandable from the following detailed explanations thereof, when read in conjunction with the accompanying drawing.
