<P>PROBLEM TO BE SOLVED: To provide a technique for constructing a slope face which has water permeability and water retentivity, makes it difficult for weeds to grow thickly and is effective for suppressing a heat island phenomenon as well. <P>SOLUTION: A slope face structure 17 including a surface layer 14 is formed by spraying a kneaded object 7 formed by mixing and agitating a soil material, a cement-based solidification agent, a granulator and water toward a ground surface 8 where a zinc-plated wire net 9 is spread by using a mortar spray gun 13. Since the surface layer 14 constituting the slope face structure 17 is a porous structure as hard as an asphalt pavement and denser than the asphalt pavement, even when seeds of weeds fly to the surface of the surface layer 14 after construction, it is hard for them to survive, germination of seeds of weeds present in the ground 18 is shielded by the surface layer 14, and weeds are prevented from growing thickly as a result. Also, since continuous gaps are present in the surface layer 14 after being solidified, the slope face structure 17 has water permeability and water retentivity in a well balanced manner. <P>COPYRIGHT: (C)2012,JPO&INPIT |
