DRAINAGE MEMBER AND DRAINAGE SYSTEM
To provide a drainage system achieving downsizing, with an improved drainage capacity.SOLUTION: A drainage member 5A comprises a projection 53 projecting toward a second wall surface 50c on the outer peripheral side of a bent channel 5c from a first wall surface 50b on the inner peripheral side of the bent channel 5c, such that a contracted part 5c1, where the cross section of the bent channel 5 connecting the a first opening 5a directed upstream of a drainage system to a second opening 5b directed downstream of the drainage system is smaller than the cross section of the second opening 5b, is present between a corner 5d on the inner peripheral side of the bent channel 5c and the second opening 5b. The projection 53 has an end face 530 at a second part P2 downstream of the drainage system in comparison with a first part P1 having a minimum channel cross section in the contracted part 5c1. When H1 represents the height of the projection 53 at the first part P1, and H2 represents the height of the projection 53 at the second part P2, 0.05H1≤H2≤0.90H1.SELECTED DRAWING: Figure 4
【課題】小型化を可能にしながら排水能力を向上できる排水システムを提供する。【解決手段】排水部材５Ａは、排水システムの上流側に向けられる第１開口５ａと排水システムの下流側に向けられる第２開口５ｂとをつなぐ屈曲流路５の流路断面積が第２開口５ｂの断面積よりも小さくなる縮小部位５ｃ１が屈曲流路５ｃの内周側の角５ｄと第２開口５ｂとの間に存在するように屈曲流路５ｃの内周側の第１壁面５０ｂから屈曲流路５ｃの外周側の第２壁面５０ｃに向かって突出する突出部５３を備える。突出部５３は、縮小部位５ｃ１において流路断面積が最小となる第１部位Ｐ１よりも排水システムの下流側の第２部位Ｐ２に端面５３０を有する。第１部位Ｐ１での突出部５３の高さをＨ１、第２部位Ｐ２での突出部５３の高さをＨ２とすると、０．０５Ｈ１≦Ｈ２≦０．９０Ｈ１である。【選択図】図４
