BANKING STRUCTURE
To provide a banking structure capable of damming sediment caused by collapse of a slope, even when the collapse of the slope occurs to the banking of a dike.SOLUTION: A first steel sheet pile wall 20 is installed along the continuous direction of a dike 10 on a downstream side of a downstream-side slope shoulder 13a positioned on the most upstream side of the dike 10. A head part 20b of the first steel sheet pile wall 20 is protruded upward from a downstream-side slope toe 13e to dam the sediment caused by collapse of a slope downstream the dike 10 by the head part 20b of the first steel sheet pile wall 20. Accordingly, damage to the downstream side can be suppressed, caused by the sediment moving over the first steel sheet pile wall 20, even when the slope collapses by an earthquake or the like.SELECTED DRAWING: Figure 1
【課題】堤防等の盛土に法面崩壊が生じても、当該法面崩壊による土砂を堰き止めることができる盛土の構造を提供する。【解決手段】堤防１０の最も上流側に位置する下流側法肩１３ａよりも下流側において、第１鋼矢板壁２０が、堤防１０の連続方向に沿って設けられ、第１鋼矢板壁２０の頭部２０ｂを下流側法尻１３ｅより上方に突出させ、第１鋼矢板壁２０の頭部２０ｂによって堤防１０の下流側の法面崩壊による土砂を堰き止める。したがって、地震等により法面崩壊したとしてもその土砂が第１鋼矢板壁２０を越えて移動し下流側に被害を及ぼすことを抑制することができる。【選択図】図１
