REINFORCEMENT STRUCTURE FOR LEVEE BODY
To provide a reinforcement structure for levee bodies: that is sufficiently resistant to water pressure that is applied to a levee body when the pondage in a dam lake increases in order to prevent the breakdown of the levee body; for which reinforcement can be performed depending on the reinforcement properties of each part of the levee body; and that can reduce the construction costs and period further compared with conventional ones.SOLUTION: A steel sheet pile wall 15 that is formed of a plurality of steel sheet piles 16 being connected in an extending direction of a levee body 10 is installed inside the levee body 10, along the extending direction of the levee body 10 so that an upper end of the steel sheet pile wall 15 is aligned with a top end 10a of the levee body 10. A part of a lower end of the steel sheet pile wall 15 and a part of a side end of the steel sheet pile wall 15 are located inside a natural ground 12 around the levee body 10.SELECTED DRAWING: Figure 3
【課題】谷池の貯水量が増加した際に堤体に作用する水圧に十分に抵抗して、堤体の崩壊を抑止できるとともに堤体各部位の強度特性に応じた補強が可能であり、さらに従来に比して工費・工期を短縮できる堤体の補強構造を提供する。【解決手段】堤体１０の内部に、複数の鋼矢板１６を堤体１０の延在方向に連結してなる鋼矢板壁１５が、堤体１０の延在方向に沿って、かつ上端を堤体１０の天端１０ａに揃えて設置され、鋼矢板壁１５の下端の一部および鋼矢板壁１５の側端の一部が堤体１０の周囲の地山１２の内部に位置している。【選択図】図３
