INNER SUB-PIPE JOINT
To provide an inner sub-pipe joint that can prevent wastewater from stagnating inside.SOLUTION: An inner sub-pipe joint 1 includes a cylindrical vertical pipe portion 11 extending in the vertical direction on the front side of the inner sub-pipe joint, and an extended pipe portion 18 extending from the vertical pipe portion 11 to a drainage inlet 19. As the inner sub-pipe joint has a recess 20 on the inner circumferential bottom surface of the extended pipe portion 18 that extends downwardly sloping toward an inner circumferential surface 11c of the vertical pipe portion 11, wastewater can be prevented from stagnating in the extended pipe portion by allowing the wastewater flowing into the extended pipe portion 18 to flow out to the vertical pipe portion 11 through the recess 20, thereby reducing the influence of foreign matter and conveyed materials contained in the stagnant wastewater on the drainage performance.SELECTED DRAWING: Figure 6
【課題】内部に排水が滞留することを防止できる内副管継手を提供すること。【解決手段】内副管継手1が、その前面側に上下方向に延びる筒状の縦管部11と、縦管部11から排水流入口19に延びる延設管部18と、を有しており、延設管部18の内周底面に、縦管部11の内周面11cに向かって下方に傾斜して延びる凹欠部20が形成されているため、延設管部18内に流入した排水を凹欠部20を通じて縦管部11に流出させることで、延出管部内に排水が滞留することを防止できるため、滞留した排水に含まれる夾雑物や搬送物による排水性能への影響を抑制できる。【選択図】図6
