SCOURING PREVENTION STRUCTURE
To provide a scouring prevention structure capable of exerting a high scouring prevention effect by structure of coating the upper part of a transpiration preventing layer having a transpiration preventing function, by a coating layer having a wave force dispersion function.SOLUTION: A scouring prevention structure 1 is formed of filling materials 20 filled in a gabion 10, the gabion 10 has a cage body 11 and an inner cage 12, the cage body 11 is formed of a bottom net 11b, a side net 11a and a cover face net 11c, and the inner cage 12 is formed of a bottom panel 12b, side panels 12a and a cover panel 12c. A mesh size of the inner cage 12 is smaller than that of the cage body 11, the filling materials 20 are formed of coarse grain materials 21 and fine grain materials 22. A transpiration preventing layer La is formed of the fine grain materials 22 filled in the inner cage 12, and a coated layer Lb is formed of the coarse grain materials 21 filled on the cover panel 12c in the cage body 11.SELECTED DRAWING: Figure 1
【課題】吸出し防止機能を有する吸出し防止層の上部を、波力分散機能を有する被覆層で被覆した構造によって、高い洗掘防止効果を発揮可能な洗掘防止構造体を提供すること。【解決手段】本発明の洗掘防止構造体１は、布団篭１０内に中詰材２０を充填してなり、布団篭１０は篭本体１１と内篭１２を備え、篭本体１１は底面網１１ｂと側面網１１ａと蓋面網１１ｃとからなり、内篭１２は底面パネル１２ｂと側面パネル１２ａと蓋面パネル１２ｃとからなり、内篭１２の網目寸法は篭本体１１の網目寸法より小さく、中詰材２０は粗粒材２１と細粒材２２とからなり、内篭１２内に充填した細粒材２２によって吸出し防止層Ｌａを構成し、篭本体１１内における蓋面パネル１２ｃ上に充填した粗粒材２１によって被覆層Ｌｂを構成したことを特徴とする。【選択図】図１
