Abstract

PROBLEM TO BE SOLVED: To improve a town amenity function, by spreading a natural lawn on the top of an artificial bed soil of a specific structure, pouring water to the bottom of the artificial bed soil and greening an artificial ground lawn which comprises a lightweight bed soil resist to stepping pressure, is readily executed and can be efficiently watered. SOLUTION: A water-barrier sheet 2 is laid so that water flows on an artificial ground 1 to make a bed face. An artificial bed soil 6 comprising a plant growing mat 3 which is a plastic crimped fiber mat containing >=40wt.% of thermally fusible conjugate fibers having 100-5,000d/f fineness having crimp and have contact points of mutual fibers fixed by the fusing of the thermally fusible conjugate fibers, having 0.02-0.15g/cm<3> density and 1-15cm thickness and a culture soil 4 such as perlite in a granular or short fiber form is spread on the bed face. A natural lawn 5 is applied to or lawn grass seeds are sowed in the top of the artificial bed soil 6 and water is poured to the bottom part of the artificial bed soil 6 to green the artificial ground lawn.

The lawn was greened by a method of producing unit grass having a thickness of about 10 cm to which the soil is attached and arranging the unit grass. However, the problem is that the floor soil is heavy, and in order to be lightweight even when it contains water, it is strictly required to thin the floor soil layer and make it lighter as a prerequisite for lawn greening of artificial ground such as rooftops. It Conventional soil for artificial ground is not suitable for lawn management that requires constant pedaling pressure due to the low hardness and vapor phase rate of the floor soil when drawing water such as after rain. It has drawbacks such as excessive water content and weakness in pedaling. Usually, the soil layer is 10-2
The grass is stretched to 0 cm or more, but when it is constructed on the seaside, the layer is thick and the salt accumulated by seawater does not flow completely, so salt damage easily occurs. In addition, there is an inconvenience that unevenness occurs when irrigating with a sprinkler, and the surrounding areas other than the lawn get wet.

易である。As can be seen from Table 1 and FIG. 3, the floor soil in the method or apparatus of the present invention has a high hardness when absorbing water and therefore is strong against pedaling pressure and has a high gas phase rate, so that it promotes the extension of the lawn root. . Further, as can be seen from FIGS. 4 and 5, the method or apparatus according to the present invention is such that even if the thickness of artificial floor soil or unit grass is thinned, the temperature of general outdoor lawn where the thickness of grass soil is 10 to 20 cm. Not much different from a change. Therefore, according to the present invention, even in the artificial ground, the grass grows as healthy as grass grown in general soil. As can be seen from FIG. 6, the lawn produced by the method or apparatus of the present invention has a water loss of 6 to 8
Since it is liter / m 2 , application of the method or apparatus of the present invention to artificial ground of a building such as a rooftop can contribute to improvement of cooling efficiency of a building and heat island.
Further, since the artificial floor soil and unit grass used in the method and apparatus of the present invention are based on a mat obtained by crimping plastic fibers, even if it has the same thickness as conventional general soil, it is lightweight and does not collapse its shape. However, even if the thickness is reduced as described above, it can be sufficiently used. Therefore, construction is easy.

上が期待できる。When the method and apparatus of the present invention is applied to greening artificial ground such as a rooftop with lawn, it is resistant to trampling due to its high hardness when absorbing water, and it has a high gas phase ratio of the soil floor, which results in rooting. A good lawn grows and effective greening is possible,
It is lightweight and does not lose its shape, so construction is easy, there is no need to waste water and there is no worry of getting wet around the area other than the lawn, and because the thickness of the floor soil can be made thin, salt damage will occur when it is constructed at the seaside. Not doing that, and further, the effect of improving the cooling efficiency of the building and contributing to the heat island can be obtained. By applying the method and apparatus of the present invention to artificial ground, improvement of urban amity function can be expected.
