ARTIFICIAL TURF LAYING STRUCTURE AND ARTIFICIAL TURF MANAGEMENT METHOD

To provide an artificial turf laying structure into which a spear is easily stuck and which is excellent in the self-supporting property of the stuck spear, and a method for managing the artificial turf laying structure.SOLUTION: In an artificial turf laying structure having an artificial turf body 1 in which piles 2 are erected on a sheet-like base material 4, and a first layer 6 made of a hard granular material 5 filled between the piles 2 of the artificial turf body 1, the first layer 6 has a water retention rate of 20 to 85%. The hard granular material 5 is preferably silica sand, and a thickness h of the first layer is preferably 90 to 110 mm.SELECTED DRAWING: Figure 1 【課題】ヤリが刺さり易く、刺さったヤリの自立性に優れる人工芝生敷設構造と、その管理方法を提供する。【解決手段】シート状基材４にパイル２が立設された人工芝生本体１と、該人工芝生本体１の該パイル２間に充填された硬質粒状物５よりなる第１の層６とを有する人工芝生敷設構造において、該第１の層６の滞水率が２０～８５％であることを特徴とする人工芝生敷設構造。前記硬質粒状物５は硅砂が好ましく、前記第１の層の厚さｈは９０～１１０ｍｍが好ましい。【選択図】図１
