VERTICAL TYPE RAINWATER PERMEATION FACILITY
To provide a vertical type rainwater permeation facility in which the clogging of a filter body and a permeation hole peripheral wall surface is hardly occurred, and the permeation capacity of the permeation hole peripheral wall surface can be maintained for a long time.SOLUTION: The vertical type rainwater permeation facility comprises: a permeating body 2 installed in a permeation hole A right under a catch basin 1; and a filter body 3 installed in the catch basin 1, penetrating a bottom of the catch basin 1 and communicating with the permeating body 2. The filter body 3 is composed of a filter 14, a filter housing cage 15 inscribed with a filter 14, and a filter protection frame 13. The filter 14 is composed of an upper filter 14a and a top end filter 14c having water permeability, and a lower filter 14b having a lower water permeability than the filters 14a, 14c. A rainwater inflow hole 21 is formed in a peripheral wall of the filter protection frame 13. A large number of rainwater inflow holes 21 are formed in an upper peripheral wall of the filter protection frame 13, and a smaller number of the rainwater inflow holes 21 than the rainwater inflow holes in the upper peripheral wall is formed in a lower peripheral wall.SELECTED DRAWING: Figure 2
【課題】フィルター体及び浸透穴周壁面の目詰まりが起こり難く、浸透穴周壁面の浸透能力を長期にわたって維持できる縦型雨水浸透施設を提供する。【解決手段】集水ます1直下の浸透穴A内に設置される浸透体2と集水ます1内に設置され、集水ます1の底部を貫通して浸透体2と連通するフィルター体3とから構成する。フィルター体3はフィルター14とフィルター14が内接するフィルター収納かご15とフィルター保護枠13とから構成する。フィルター14は透水性を有する上部フィルター14a及び天端フィルター14cとこれらのフィルター14a,14cより透水性の小さい下部フィルター14bとから構成する。フィルター保護枠13の周壁に雨水流入孔21を形成する。フィルター保護枠13の上部周壁には多数の雨水流入孔21を形成し、下部周壁に上部周壁より少数の雨水流入孔21を形成する。【選択図】図２
