DRAINAGE DEVICE AND INFILTRATION SYSTEM
PROBLEM TO BE SOLVED: To provide an infiltration system suitable for underground infiltration of drainage water such as rain water.SOLUTION: An infiltration system 100 includes an upper structure 3, a lower structure 1 and a concrete intermediate slab 30 which partitions an interior 71s of the upper structure 3 and an interior 21s of the lower structure 1. The intermediate slab 30 includes a first opening 41 in which drainage water flows at the normal time, which has such a size that an operator can pass therethrough, and to which a detachable filter member 50 is attached, and a second opening 42 in which the drainage water does not flow at the normal time, and has such a size that the operator cannot pass therethrough. The infiltration system 100 further includes a wall part 61 which changes the second opening 42 to the opening in which the drainage water flows by forming at least a part of a flow passage F2 in which the drainage water flows to the second opening 42 via a first position P1 upper than the intermediate slab 30 when the liquid level of the drainage water is formed on the intermediate slab 30.
【課題】雨水などの排水を地下浸透させるのに適した浸透システムを提供する。【解決手段】上部構造体３と、下部構造体１と、上部構造体３の内部７１ｓおよび下部構造体１の内部２１ｓを仕切るコンクリート製の中間スラブ３０とを有する浸透システム１００であって、中間スラブ３０は、通常時において排水が流れ、作業員が通ることができる大きさの第１の開口部４１であって、着脱式のフィルター部材５０が取り付けられる第１の開口部４１と、通常時において排水が流れず、作業員が通ることができない大きさの第２の開口部４２とを含み、さらに、中間スラブ３０の上に排水の液面が形成されたときに、排水が中間スラブ３０よりも上方の第１の位置Ｐ１を経由して第２の開口部４２に至る流路Ｆ２の少なくとも一部を形成することにより、第２の開口部４２を排水が流れる開口部に変える壁部６１を有する。【選択図】図１
