To provide a culvert structure using a precast concrete member, that can suppress thickness of the member and can achieve both improvement in safety and durability and reduction in manufacturing cost, without using a hinge structure.SOLUTION: The arch culvert constructed by assembling a plurality of members comprises: an arch member constructed along a substantially semi-elliptical arch axis line, and a footing member that is installed on an installation surface that is the foundation ground and is provided as a foundation member that is connected to lower ends of left and right side wall parts of the arch member, wherein the footing member is connected to the arch member in a state in which a projecting width of the footing member to a culvert outer side is larger than the projecting width of the footing member to a culvert inner side.SELECTED DRAWING: Figure 5
【課題】プレキャストコンクリート部材を用いたカルバート構造物において、ヒンジ構造を用いることなく、部材厚の厚みを抑え、安全性や耐久性の向上と製造コストの低減を両立させる。【解決手段】複数の部材を組み立てて構築されるアーチカルバートであって、略半楕円形状のアーチ軸線に沿って構成されるアーチ部材と、基礎地盤である設置面上に設置され、前記アーチ部材の左右両側壁部の下端に接続する基礎部材として設けられるフーチング部材と、を備え、前記フーチング部材は、当該フーチング部材のカルバート外側への張り出し幅が、当該フーチング部材のカルバート内側への張り出し幅よりも大きい状態で前記アーチ部材に接続されることを特徴とする、アーチカルバートが提供される。【選択図】図５
