METHOD OF PROTECTING SLOPE HAVING EXISTING SLOPE FRAME AND SYSTEM OF PROTECTING SLOPE
To provide a method of protecting a slope having an existing slope frame and a system of protecting a slope having an existing slope frame which enable effective protection of a slope having an existing slope frame.SOLUTION: This is a method of protecting a slope S on which a slope frame 2 are installed. The method has an anchor and netting step of disposing in a scattered manner anchors 12 interspersed in the slope S of an existing slope frame 2 in a region where the frame member does not exist and expanding a net body 14 from above the slope frame 2 with respect to the slope S, and a net body pressing down step of fixing a press-down member 20 to the anchor 12 in a state where the net body 14 is pressed down to a position lower than a height position of a top surface 2c of the slope frame 2 by the press-down member 20 having a length greater than at least the meshes of the net body 14. As a result, the net body 14 is pressed down to a position lower than the height position of the slop frame top surface 2c by the press-down member 20, the slope S is pressed against the net body 14 via the slope frame 2, so that the lack of proof stress of the slope frame 2 is supplemented by the net body 14, enabling effective protection of the slope having the existing slope frame.SELECTED DRAWING: Figure 3
【課題】既設法枠を有する斜面の有効な保護を可能とする、既設法枠を有する斜面の保護方法及び既設法枠を有する斜面の保護システムを提供する。【解決手段】法枠２が設置されている斜面Ｓの保護方法である。本方法は、既設の法枠２内における枠部材の存在しない領域の斜面Ｓにアンカー１２を点在させて設置するとともに斜面Ｓに対して法枠２上から網体１４を展設する、アンカー及び網体設置工程と、少なくとも網体１４の網目より大きい長さを有する押下材２０によって網体１４を法枠２の天面２ｃの高さ位置よりも低い位置に押下げた状態で押下材２０をアンカー１２に固定する網体押下工程と、を有する。これにより、網体１４が押下材２０によって法枠天面２ｃの高さ位置よりも低い位置に押下げられることから、斜面Ｓは法枠２を介して網体１４に押圧されて法枠２の耐力不足が網体１４により補われ、既設法枠を有する斜面の有効な保護が可能となる。【選択図】図３
