SCOURING PREVENTION UNIT AND SCOURING PREVENTION STRUCTURE
To provide, by combining a deformation tracking function and a stress dispersion function, a scouring prevention unit with a persistent configuration that can resist in a whole structure to a local fast water flow caused by a tsunami or the like, and a scouring prevention structure that can exert a high scouring prevention effect and a suction prevention effect by a ground restraint function.SOLUTION: A restraint surface material 20 with flexibility that can follow the undulations of a ground and a plurality of root hardening materials 10 arranged on the restraint surface material 20 and fixed to the restraint surface material 20 are provided. Each of the root hardening materials 10 has a bag body 11 made of knitted fabric and a filling material filled inside the bag body, and the ground on the back surface of the restraint surface material 20 can be restrained via the restraint surface material 20 by the load of the plurality of root hardening materials 10.SELECTED DRAWING: Figure 2
【課題】変形追従機能と応力分散機能の組合せによって、津波などによる局所的な速い水流に対して構造全体で抵抗可能な、粘り強い構造の洗堀防止ユニットと、地盤拘束機能によって高い洗堀防止効果と吸出し防止効果を発揮可能な洗堀防止構造を提供する。【解決手段】地盤の起伏に追従可能な柔軟性を備える拘束面材２０と、拘束面材２０上に配列して拘束面材２０に固定した複数の根固め材１０とを備え、複数の根固め材１０はそれぞれ編地からなる袋体１１と袋体の内部に充填した中詰材を有し、複数の根固め材１０の荷重によって拘束面材２０を介して拘束面材２０背面の地盤を拘束可能に構成した。【選択図】図２
