ARTIFICIAL LAWN LAYING STRUCTURE
PROBLEM TO BE SOLVED: To provide an artificial lawn field capable of holding a throwing event, wherein the field can be easily prepared.SOLUTION: After laying a first artificial lawn 2 on a foundation layer 1, a first packed layer 24 which has a thickness that generally reaches the upper end of turf 21 planted on the first artificial lawn is formed; and subsequently, a second artificial lawn 3 which has a second packed layer 34 formed in a thickness larger than the first packed layer is laid over the upper face of the first artificial lawn. The second packed layer is formed in the second artificial lawn in a thickness larger than the thickness of the first packed layer; therefore, even when a throwing event such as javelin throw is held, the insertion of the gear for a throwing event is stopped at the second packed layer. Even when the gear for a throwing event penetrates through the second artificial lawn, the gear for a throwing event is stopped at the first packed layer; thus the gear for a throwing event is prevented from getting damaged.
【課題】容易に製造可能で、投擲競技が実施できる人工芝生競技場を提供する。【解決手段】基礎層１の上方に第一の人工芝生２を敷設し、この第一の人工芝生に植設させた芝葉２１の略上端に至る厚みを有する第一の充填層２４が設けるとともに、第一の充填層より大きな厚みに形成させた第二の充填層３４を有する第二の人工芝生３を第一の人工芝生の上面に敷設する。第二の人工芝生に設ける第二の充填層を、第一の充填層より大きな厚みに形成するので、槍投げなどの投擲競技を行っても、投擲用具の挿入が第二の充填層で止まり、また、第二の人工芝生を貫通しても第一の充填層で投擲用具を停止させ、投擲用具の損傷などを抑制させることができる。【選択図】図１
