STRUCTURE AGAINST DEBRIS FLOW
To provide a structure which reduces impact of a structure received from sand and stone and can maintain an original form, when damming up a debris flow generated in a mountain stream where a debris flow is assumed to generate.SOLUTION: A structure 1 against debris flow is composed of a structure 2 which is three-dimensionally constructed on a plate-like foundation 11 constructed on a river bed 26, and a tensile material 13 which is built between at least the ground on both banks of a mountain stream and the structure 2, where ends on both the banks are fastened to the ground, bears impact force from sand and stone at the time of generation of a debris flow together with the structure 2, wherein the structure 2 is composed of a plurality of lower frame materials 3 which are arranged side by side in a width direction of the mountain stream on the foundation 11 and are arranged in a debris flow direction, a front side vertical frame material 4 and a rear side vertical frame material 5 which are joined to the upstream side and the downstream side in an axial direction of each of the lower frame materials 3 and are erected from the lower frame materials 3, and a joint material 6 for connecting at least the lower frame materials 3 and 3 adjacent to each other in the width direction of the mountain stream, and the tensile material 13 is brought into contact with or connected to the structure 2 so that the lower frame materials 3 are relatively movable in the axial direction to the foundation 11.SELECTED DRAWING: Figure 1
【課題】土石流の発生が想定される渓流に発生した場合の土石流を堰き止める上で、構造体が土石から受ける衝撃を緩和させ、本来の形態を維持可能な構造にする。【解決手段】渓床２６上に構築される平板状の基礎１１上に立体的に構築される構造体２と、少なくとも渓流の両岸の地盤と構造体２との間に架設されて両岸側の端部が地盤に定着され、土石流の発生時に土石からの衝撃力を構造体２と共に負担する引張材１３から対土石流構造物１を構成し、基礎１１上に渓流の幅方向に並列し、土石流方向に沿って配置される複数本の下部枠材３と、各下部枠材３の軸方向の上流側及び下流側に接合され、下部枠材３から起立する前方側縦枠材４及び後方側縦枠材５と、少なくとも渓流の幅方向に隣接する下部枠材３、３を互いに連結するつなぎ材６から構造体２を構成し、下部枠材３を基礎１１に軸方向に相対移動自在に引張材１３を構造体２に接触させるか、接続する。【選択図】図１
