WASTEWATER DRAINING DITCH MEMBER AND METHOD FOR INSTALLING THE SAME

PROBLEM TO BE SOLVED: To provide a wastewater draining ditch member having a conduit member with a draining channel and a detachable cover member covering over the draining channel, the wastewater draining ditch member having improved water-tightness and being applicable when a large amount of wastewater is drained.SOLUTION: A conduit member has a vertical groove 7 extending in a longitudinal direction on outside of a draining channel. Ribs 9, 10 that protrude inward in the vertical groove 7 and extend in the longitudinal direction are provided on both side walls of the vertical groove 7. The two ribs 9, 10 are elastically deformable such that a distance therebetween is widened when a prescribed load is exerted in a vertical direction. A cover member 11 has a protruded line part on a rear surface, the protruded line part protruding downward and extending in the longitudinal direction. The protruded line part has a small-diameter part 13 and a large-diameter part 14 on each of a base end side and a tip side. The two ribs 9, 10 come in contact with a step part 15 formed by the small-diameter part 13 and the large-diameter part 14 while the protruded line part is housed in the vertical groove 7.SELECTED DRAWING: Figure 8 【課題】排水路を有する通水部材と、該排水路の上方を覆う着脱自在な蓋部材とを備えるドレイン排水溝部材において、その水密性を向上させて、多量のドレイン水を排水する場合にも適用できるようにすること。【解決手段】通水部材は、排水路の外側に、長手方向に延びる縦溝７を有し、縦溝７の内側に突出し且つ長手方向に延びるリブ９、１０が、縦溝７の両側壁に設けられており、２つのリブ９、１０は、上下方向から所定の荷重が与えられることによってその間の距離が離間するように弾性変形可能であり、蓋部材１１は、下方に突出し且つ長手方向に延びる突条部を裏面に有し、突条部は基端側及び先端側のそれぞれに小径部１３及び大径部１４を有し、突条部が縦溝７の中に収容されているときに、小径部１３と大径部１４とがなす段部１５に２つのリブ９、１０が当接している。【選択図】図８
