PROBLEM TO BE SOLVED: To provide a material for filtration which has a simple structure which can be easily produced at a construction site, and exhibits excellent water purification action.SOLUTION: A material 100 for filtration comprises a bottomed storage member 10 having a substantially cylindrical shape; and a filter medium 20 which is charged into the storage member 10. The filter medium 20 can be withdrawn from the storage member 10. The storage member 10 has an opening 11 in which muddy water can be injected, and a water permeable region 12 which is formed by provision of plural open holes 14 on a bottom plate 13. A peripheral wall 10a of the storage member 10 has a shape that a diameter thereof is continuously expanded toward the opening 11 from the bottom plate 13, and a front view shape of the storage member 10 is an inverted conical trapezoidal shape. The filter medium 20 charged into the storage member 10 is formed from a soil material, a cement system solidification material and an aggregation agent, and has an aggregation structure including a continuous fine air gap.SELECTED DRAWING: Figure 2
【課題】工事現場で容易に製作可能な簡素な構造であり、優れた浄水作用を発揮する濾過用資材を提供する。【解決手段】濾過用資材１００は、有底で略円筒形状の収容部材１０と、収容部材１０内に充填された濾過材２０と、を備えている。濾過材２０は収容部材１０から離脱可能である。収容部材１０は、濁水を注入可能な開口部１１と、底板１３に複数の貫通孔１４を開設することによって形成された透水領域１２と、を有している。収容部材１０の周壁１０ａは底板１３から開口部１１に向かって連続的に拡径した形状をなし、収容部材１０の正面視形状は倒立円錐台形状をなしている。収容部材１０内に充填された濾過材２０は、土材、セメント系固化材及び団粒化剤で形成され、連続微細空隙を含む団粒構造を有している。【選択図】図２
