To provide a sloped face protection structure capable of preventing collapse of a sloped face at a lower price than a conventional one.SOLUTION: In a protection structure 11 of a sloped face 1 having a dangerous area 3 where a plurality of standing trees 2 are erected and occurrence of a sediment disaster is assumed, standing trees 2 in the dangerous area 3 and standing trees 2 in a stable area 4 other than the dangerous area are connected by a rope material 12. When collapse occurs in the dangerous area 3, collapse more than the collapse can be prevented and collapse energy can be attenuated by the rope material 12 connecting the standing tree 2 in the dangerous area 3 and the standing tree 2 in the stable area 4. Also, since the plurality of rope materials 12 are provided at multiple stages with an interval in a slope direction of the sloped face 1, standing trees 2 which are connected with a plurality of standing trees 2 at both sides of the dangerous area 3 and which are connected with the rope material 12 provided in multiple stages in the slope direction of the sloped face 1 work as an anchor.SELECTED DRAWING: Figure 1
【課題】従来に比べて安価にして斜面の崩壊を防止することができる斜面保護構造を提供する。【解決手段】複数の立木２が立設され、土砂災害の発生が想定される危険区域３を有する斜面１の保護構造１１において、危険区域３の立木２と危険区域以外の安定区域４の立木２とをロープ材１２により連結したから、危険区域３に崩壊が発生すると、危険区域３の立木２と安定区域４の立木２とを連結するロープ材１２により、それ以上の崩壊を防止又は崩壊のエネルギーを減衰することができる。また、複数のロープ材１２を斜面１の傾斜方向に間隔を置いて多段に設けたから、危険区域３の両側の複数の立木２に連結されると共に、斜面１の傾斜方向に多段に設けたロープ材１２に連結した立木２がアンカーとして作用する。【選択図】図１
