LEVEE BODY SEEPAGE DESTRUCTION SUPPRESSION STRUCTURE
To provide a levee body seepage destruction suppression structure that can suppress seepage destruction of a levee body installed around a reservoir and enables reduction in construction costs/construction periods as compared with the conventional structures.SOLUTION: A levee body seepage destruction suppression structure includes: a steel sheet pile wall 15a installed on an upstream slope face 10b on the upstream side of a levee body 10 and at a high-water position 12 having a height equal to a normal high-water level of a reservoir 11 or in the vicinity thereof, the steel sheet pile wall installed along a direction, in which the levee body 10 extends, and so as to protrude upward; and a protection part 20 for protecting the upstream slope face 10b over the high-water position 12 or the vicinity thereof, the protection part 20 also being a filled type seepage prevention part 21 made of an impermeable material filled between the steel sheet pile wall 15a and the upstream slope face 10b. Thereby, seepage destruction of the levee body 10 can be suppressed and construction costs/construction periods can be reduced as compared with the conventional structures.SELECTED DRAWING: Figure 1
【課題】ため池の周囲に設けられた堤体の浸透破壊を抑止できるとともに、従来に比して工費・工期を短縮できる堤体の浸透破壊抑止構造を提供する。【解決手段】堤体１０の上流側の上流法面１０ｂでかつため池１１の常時満水位と等しい高さの満水位置１２またはその近傍に、鋼矢板壁１５ａが堤体１０の延在方向に沿って、かつ上方に突出するように設置され、満水位置１２またはその近傍より上側の上流法面１０ｂを保護する保護部２０が設けられ、保護部２０は、鋼矢板壁１５ａと上流法面１０ｂとの間に充填された不透水性材料からなる充填型浸透防止部２１であるので、堤体１０の浸透破壊を抑止できるとともに、従来に比して工費・工期を短縮できる【選択図】図１
