PROTECTIVE STRUCTURE
PROBLEM TO BE SOLVED: To provide a protective structure capable of restricting an impact added on a protective surface to a lower level even if multiple stones continuously fell onto the structure.SOLUTION: A protective structure comprises: a protective surface 18a, which is a top face of a roof part 18 that receives a fallen object on a slope; and a first buffer layer 50, which is EVA resin foam and disposed on a slope side of the protective surface 18a through a second buffer layer 40. The first buffer layer 50 is formed with alternate layers of a highly hard EVA resin foam layer 54 and a low hard EVA resin foam layer 52 in thickness direction and the highly hard EVA resin foam layer 54 is disposed on an upper side of the first buffer layer that is closer to the slope.SELECTED DRAWING: Figure 2
【課題】複数の落石が連続した場合でも、防護面に加わる衝撃を小さく抑えることができる保護構造物を提供する。【解決手段】斜面落下物を受け止める屋根部１８の上面が防護面１８ａであり、防護面１８ａの斜面側に、第二の緩衝層４０を介して、ＥＶＡ樹脂発泡体である第一の緩衝層５０を備える。第一の緩衝層５０は、高硬度のＥＶＡ樹脂発泡体の層５４と低硬度のＥＶＡ樹脂発泡体の層５２とが厚み方向に交互に重なって形成され、斜面に近い上側に、高硬度のＥＶＡ樹脂発泡体の層５４を有する。【選択図】図２
