る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a drainage channel material which is used as a material for civil engineering in a soil structure such as cut soil or embankment or as a planting material in artificial ground.

けられる。[Background Art and its problems] For the soil structure formed by soil or ground, cut soil formed by cutting the original ground and embankment constructed by building earth and sand on the foundation ground, and these There are slopes that are incidental structures, and these soil structures are generally provided with drainage to stabilize the structures.

駐車場の上に公園を造ったり、あるいは逆に公園の下に
駐車場を建設するなど、土地の高度利用化に伴い人工地
盤への植栽はますます増大しつつある。Further, since there is little room for creating a green space in a densely populated urban area, conventional measures have been taken to create a green space by, for example, greening the rooftop of a building. The foundation prepared on the impermeable structure constructed artificially is called artificial ground, and planting has started on this. afterwards,
The planting on artificial ground is increasing more and more due to the advanced utilization of land, such as constructing a park on the parking lot or vice versa.

敷設作業中、シートと共に飛散し易い。Generally, the artificial ground is constructed by placing a drainage layer and a soil layer for planting on an impermeable support structure, and the artificial ground is planted. Therefore, surplus water such as rainwater that has fallen on the artificial ground flows out through the drainage layer and into the drainage channel provided under the support structure. As a drainage layer,
Heretofore, finely divided perlite that is aseptic and has good water retention and drainage properties has been used. However, since perlite is very light, even if you lay a sheet on it,
Easily scattered with the sheet during laying work.

妨げるという欠点が生じていた。[0005] Recently, as an alternative method, a drainage channel material in which a styrofoam material is packed in a cloth bag is laid as a drainage layer to form an artificial ground. According to this method, it is possible to save the labor of sprinkling perlite or laying a sheet only by laying a water-permeable drainage channel material. However, even if the above-mentioned drainage channel material is used, there is a drawback that the soil flows into the gap between the drainage channel materials that are laid adjacent to each other from above, builds a weir inside the artificial ground, and prevents drainage.

Alternatively, it is an object of the invention to provide a drainage channel material suitable as a planting material for artificial ground.

ない。In order to connect the drainage channel materials, the edge portions of the other drainage channel materials that do not have the edge cloth are brought into contact with the edge portions of the drainage channel material that do not have the edge cloth. The whole is covered with the hem cloth. Thus, if the entire gap formed between the drainage channel materials is closed with the edge cloth, even if the soil layer is placed on the drainage channel material and the soil layer is placed, the soil flows into the gap and the inside of the ground is filled. There is no possibility of building a weir or blocking the soil by draining it into a downstream drainage channel communicating with the drainage channel material.
