しかしながら、特許文献１に記載の人工芝では、転倒、スライディング等が行われる激しい運動が実施される場合において、人工芝の芝目に弾性粒状体を充填しているため、太陽光の紫外線等に曝され経年変化により弾性粒状体の弾性が損なわれると、アスファルトやコンクリートから構成された基盤の上に敷設され人工芝の下部に敷設された緩衝材が有する弾性のみとなり、満足な衝撃吸収性が得られ難いという問題があった。   However, in the artificial turf described in Patent Document 1, when intense exercises such as falling, sliding, etc. are carried out, the artificial turf turf is filled with elastic granular materials, so that the ultraviolet rays of sunlight etc. If the elasticity of the elastic granular material is impaired due to exposure and aging, it will be only the elasticity of the cushioning material laid on the base made of asphalt or concrete and laid on the lower part of the artificial turf, and satisfactory shock absorption There was a problem that it was difficult to obtain.

本発明は上記の如き課題を解決するためになされたものであり、人工芝が敷設される区域に、長期間にわたり充分な衝撃吸収性を提供せんとするものである。   The present invention has been made in order to solve the above-described problems, and is intended to provide sufficient impact absorption for a long period of time in an area where artificial grass is laid.

上記目的を達成するため、本発明は以下のような構成としている。
すなわち、本発明に係る人工芝の下地構造は、基材と、基材に植設された多数のヤーンからなるパイルと、パイル間に充填された充填材とを備えた人工芝の下部構造であって、基盤上に、弾性を備え且つ粒状物からなる衝撃吸収層が形成され、該衝撃吸収層上に、衝撃吸収層より小径の粒状物からなる下地層が形成されていることをを特徴とするものである。 In order to achieve the above object, the present invention is configured as follows.
That is, the artificial turf ground structure according to the present invention is a substructure of an artificial turf comprising a base material, a pile made of a number of yarns planted on the base material, and a filler filled between the piles. A shock absorbing layer having elasticity and made of granular material is formed on the substrate, and a base layer made of granular material having a smaller diameter than the shock absorbing layer is formed on the shock absorbing layer. It is what.

また、本発明は前記構成に加えて、前記衝撃吸収層の下に透水性を有するシートが敷設されていることを特徴とするものである。   In addition to the above configuration, the present invention is characterized in that a sheet having water permeability is laid under the shock absorbing layer.

本発明に係る人工芝の下部構造によれば、基盤上に、弾性を備え且つ粒状物からなる衝撃吸収層を形成すれば、コンクリートやアスファルト等の基盤に代わる衝撃吸収層を人工芝の基材の下側にもうけているため、太陽光が衝撃吸収層に直接照射されるのを防ぐことができ、長期間にわたり衝撃吸収性を維持することができる。また、前記衝撃吸収層上に、衝撃吸収層より小径の粒状物からなる下地層を形成すれば、人工芝の基材の表面を平滑且つ安定化させることができる。   According to the lower structure of the artificial turf according to the present invention, if a shock absorbing layer made of a granular material is formed on the base, the base of the artificial turf is used as a shock absorbing layer instead of the base such as concrete or asphalt. Since it is provided on the lower side, it is possible to prevent sunlight from directly irradiating the shock absorbing layer, and it is possible to maintain the shock absorbing property over a long period of time. Further, if a base layer made of granular material having a smaller diameter than the shock absorbing layer is formed on the shock absorbing layer, the surface of the artificial turf base material can be smoothed and stabilized.

更には、前記衝撃吸収層の下に透水性を有するシートを敷設するようにすれば、降雨や散水による水は当該シートを透過して排水することができると共に、当該シートの下側からの沈泥の吸い上げを遮断でき、衝撃吸収層の目詰まりを防ぐことができる。   Furthermore, if a sheet having water permeability is laid under the shock absorbing layer, water due to rain or water spray can permeate and drain the sheet and sink from the lower side of the sheet. Mud sucking can be blocked and the shock absorbing layer can be prevented from being clogged.
