DITCH COVER
To provide a ditch cover capable of preventing downstream outflow of a liquid oil leaked to a drain ditch over long hours without allowing overflow of drain from the drain ditch in an emergency.SOLUTION: A ditch cover 1 has a ditch cover body 2 covering a drain ditch G1 and a drain weir plate 3 with one end turnably pivoted to a rear face of the ditch cover body 2, around a turning axis 4. The drain weir plate 3, when turned downward from a first attitude P1 along the rear face of the ditch cover body 2, is configured to be a second attitude P2 closing a passage of the drain ditch G1 and damming. The drain weir plate 3 has a body part 30 having a hole-forming region R1 for forming multiple through-holes 33a, and a cover part 35 positioned on an upstream side in the ditch passage direction in the second attitude P2 of the body part 30. The cover part 35 covers the hole-forming region R1 so as to form a space S1 between the body part 30 and itself, and an outer peripheral part is connected to the body part 30 with no gap, excluding a region of the turning axis 4 side.SELECTED DRAWING: Figure 1
【課題】非常事態において排水溝から排水を溢れさせずに長時間に亘って排水溝に漏れ出た液状油の下流側への流出を防ぐことが可能な溝蓋を提供する。【解決手段】溝蓋１は、排水溝Ｇ１を覆う溝蓋本体２と、一端が回動軸４を中心として回動可能に溝蓋本体２の裏面に軸支された排水堰止板３とを備え、排水堰止板３は、溝蓋本体２の裏面に沿う第１姿勢Ｐ１から下方に回動させた際、排水溝Ｇ１の通路を遮って堰き止める第２姿勢Ｐ２となるよう構成される。排水堰止板３は、複数の貫通孔３３ａが形成された孔形成領域Ｒ１を有する本体部３０と、本体部３０の第２姿勢Ｐ２における溝通路方向上流側に位置するカバー部３５とを備える。カバー部３５は、本体部３０との間に空間Ｓ１が形成されるように孔形成領域Ｒ１を覆うとともに外周部分が回動軸４側の領域を除いて本体部３０に隙間無く接続される。【選択図】図１
