ARTIFICIAL LAWN LAYING STRUCTURE FOR JAVELIN THROWING
To provide an artificial lawn laying structure which is easy to pierce with a javelin, easy to construct, and being low in cost.SOLUTION: A lower layer 2 is provided on a base 1, and an upper layer 3 made of an artificial lawn 30 in which a granular material S' such as sand is filled between lawn leaves 32 is provided thereon. The lower layer 2 is obtained by filling pocket holes of a honeycomb structure 20 made of woven or non-woven fabric with a granular material S such as sand. The total thickness H+Hof the layers of granular materials S and S' is 60 mm or more. The opening area of the pocket holes of the honeycomb structure is 2,000 to 10,000 mm.SELECTED DRAWING: Figure 1
【課題】やりが刺さり易く、しかも施工が容易で低コストである人工芝生敷設構造を提供する。【解決手段】基礎１の上に下層２が設けられ、その上に砂等の粒状物Ｓ’が芝葉３２間に充填された人工芝生３０よりなる上層３が設けられている。下層２は、織布又は不織布よりなるハニカム構造体２０のポケット穴に砂等の粒状物Ｓを充填したものである。粒状物Ｓ，Ｓ’の層の合計厚さＨ１＋Ｈ３は６０ｍｍ以上である。ハニカム構造体の前記ポケット穴の開口面積が２，０００〜１０，０００ｍｍ２である。【選択図】図１
