2. Description of the Related Art Conventionally, a golf course fairway has a natural lawn vegetated to maintain and maintain the lawn manually. Recently, due to the long practice hours at golf driving ranges (early morning practice, late night practice, etc.) and lack of manpower, maintenance of natural lawns has become difficult, and synthetic resin artificial lawns are being adopted. It was

Artificial lawns used for fairways at golf driving ranges are constructed by stapling because the ground is a soil surface. Since the fairway on which the artificial lawn is constructed is flat, the practice balls can be collected with a ball collection car.

[0004]

[Problems to be Solved by the Invention] However, the conventional artificial grass has a large expansion and contraction rate due to the temperature difference, and therefore, the artificial grass contracts due to the temperature decrease in the winter and the artificial grass between the joints (joint portion). Opening is conspicuous, again
When the temperature is high in summer, the artificial lawn expands and partially expands. If the artificial lawn bulges, a practice ball will enter the bulge and it will be difficult for the ball to collect the ball. It has the drawback of damaging the artificial grass.

The present invention has been made in view of the above circumstances, and an object thereof is an artificial grass for superposing construction in which various problems due to contraction and expansion between adjacent artificial grasses caused by a temperature difference are solved at once. To provide.

[0006]

[Means for Solving the Problems] That is, the gist of the present invention is to provide a square lawn base having a large number of water-permeable holes arranged in an array, and a large number of annular leaf-shaped plants in which a plurality of leaves are planted in an annular shape. The lawn base is formed on the upper surface of at least one end of the lawn to form an overlapping portion for overlapping the ends of the lawn foundations, and the annular leaflet is a lawn surface constituent portion excluding the overlapping portion. An artificial turf for superimposing construction made of synthetic resin, which is characterized by being arranged integrally and in line with the turf base.

[0007]

[Function] The overlapping portion enables an appropriate interval to be provided between the grass surface components of each artificial grass when laying the artificial grass, and as a result, when the artificial grass contracts, the ground surface It does not conspicuously open the joint at the joint without exposing it, and when the artificial lawn expands, it acts to prevent partial expansion.
