SEDIMENT OUTFLOW PREVENTION STRUCTURE AND CONSTRUCTION METHOD FOR CONSTITUTING THE STRUCTURE
To provide a sediment outflow prevention structure which can accurately prevent collapse of a sediment laminate formed by piling up sediments at the time of sediment outflow and in which an outer surface of the sediment laminate is covered with a net body, and a construction method for constituting the structure.SOLUTION: A sediment outflow prevention structure 10 includes a sediment laminate 20 where sediments 22 are piled up on a slope S in a vertical direction in a plurality of stages, and a net body 30 fixed to the slope in the state where an outer surface of the sediment laminate is covered, and prevents sediment outflow from the slope by the sediment laminate, wherein the net body has a sediment mounted area part 34 which is laid on the slope and where the sediment laminate is mounted on an upper surface, a mountain side area part 32 which extends to a slope mountain side in the sediment mounted area and is fixed to the slope, and a sediment covering area part 36 which extends to a slope valley side of the sediment mounted area, and is folded so as to cover at least an upper surface of the mounted sediment laminate and is fixed to the mountain side area part.SELECTED DRAWING: Figure 1
【課題】土嚢を積み上げて形成された土嚢積層体の外表面を網体で覆った土砂流出防止構造において、土砂流出時に的確に土嚢積層体の崩壊を防止することが可能な土砂流出防止構造及びその構造を構成するための施工方法を提供すること。【解決手段】斜面Ｓに土嚢２２を上下方向に複数段積み上げた土嚢積層体２０と、該土嚢積層体の外表面を覆った状態で前記斜面に固定された網体３０と、を備え、前記土嚢積層体により前記斜面からの土砂流出を防止する土砂流出防止構造１０において、前記網体は、前記斜面に敷設され、上面に前記土嚢積層体が載置された土嚢載置領域部３４と、該土嚢載置領域の斜面山側に延設され、前記斜面に固定された山側領域部３２と、前記土嚢載置領域の斜面谷側に延設され、前記載置された土嚢積層体の少なくとも上面を覆うように折り返されて前記山側領域部に固定された土嚢覆い領域部３６と、を有する。【選択図】図１
