To reduce the weight of a temporary protective fence foundation by fixing an elastic sheet and an adhesive sheet on the bottom of the temporary protective fence foundation, eliminating uneven contact pressure with an uneven installation surface, and obtaining a prescribed limit sliding load.SOLUTION: A temporary protective fence foundation 1 is placed on an installation surface S on which an irregular uneven surface is formed. A urethane foam elastic sheet 3 is fixed to both ends and the central part of the bottom surface of a body 6. Protrusions 61 and 62 are provided at both ends of the main body 6 to which an urethane-based adhesive sheet 2 is fixed to the bottom surface of the elastic sheet 3 for inserting a guardrail post and connecting adjacent temporary protective fence foundations 1 to each other. The temporary protective fence foundations 1 are mutually connected by inserting a guardrail post into cylinders 61a and 62a which are projected by protrusions 61 and 62 in a state where the protrusions 61 and 62 are engaged in an overlapping manner in the plane view.SELECTED DRAWING: Figure 1
【課題】仮設防護柵基礎の底面に弾性シートと粘着シートを固着して、凹凸のある設置面との間の不均一な接地圧力を解消し、所定の限界滑動荷重を得ることで、仮設防護柵基礎の軽量化を図る。【解決手段】仮設防護柵基礎１は、不規則な凹凸が形成された設置面Ｓに載置されている。本体６の底面の両端部及び中央部に発泡ウレタン系の弾性シート３が固着されて、弾性シート３の底面にウレタン系の粘着シート２が固着される本体６の両端部には、ガードレール支柱を挿入するとともに、隣接する仮設防護柵基礎1を相互に連結するための突起部６１、６２が設けられる。突起部６１、６２を平面視で重ね合わせた状態で突起部６１、６２に突設された筒６１ａ、６２ａにガードレール支柱を挿入することで、仮設防護柵基礎１を相互に連結する。【選択図】図１
