構造を提供する。According to the fifth aspect of the present invention, there is provided a composition comprising an aliphatic polyester resin and a plant fiber at a desired position on a weed suppression sheet, wherein the composition is formed integrally with the head. A weed suppression sheet laying structure, wherein a pile formed by an insertion main body is driven into the weed suppression sheet. According to the sixth aspect of the present invention,
A pile composed of a head and an insertion main body integrally formed with the head, which is a composition blended with an aliphatic polyester resin and a plant fiber at a desired position on the road curing sheet, is placed on the road curing sheet. And a road curing sheet laying structure characterized by being driven into the vehicle. According to the seventh aspect of the present invention, the head forms a plurality of ridges extending from the apex to the end, and the insertion main body has a plurality of protrusions and a main body at a desired position on the outer periphery. The weed suppression sheet laying structure according to claim 5, wherein a plurality of ridges are formed in a longitudinal direction. According to the invention as set forth in claim 8, the head forms a plurality of ridges at a divergent portion from the apex, and the insertion main body has a plurality of protrusions and a main body at a desired position on the outer periphery. The road curing sheet laying structure according to claim 6, wherein a plurality of ridges are formed in a longitudinal direction.
