PIPE JOINT, DRAINAGE STRUCTURE AND DRAINAGE PIPE CONNECTION PART STRUCTURE
PROBLEM TO BE SOLVED: To use a pipe joint in common in a drainage flow passage even if a non-flexible drainage pipe and a flexible drainage pipe are connected to each other by the pipe joint, and each drainage pipe is connected on any of an upstream side and a downstream side of the pipe joint.SOLUTION: In a pipe joint 10, a first connection port 20 connected with a non-flexible drainage pipe is formed at one end side, and a second connection port 30 connected with a flexible drainage pipe 51 is formed at the other end side. In the second connection port 30, there are arranged an outer cylinder 31 into which an end part of the flexible drainage pipe 51 is inserted, an inner cylinder 32 inserted into an end part of the flexible drainage pipe 51 which is inserted into the outer cylinder 31, and an engagement part 40 which is engaged with a recess of the flexible drainage pipe 51, and brings the flexible drainage pipe 51 into a retained state. A drainage overflow edge 37 which is formed at an opening edge of the inner cylinder 32 is arranged at a depth side of the second connection port 30 rather than a drainage overflow edge 35 which is formed at an opening edge of the outer cylinder 31. A clearance between the outer cylinder 31 and the flexible drainage pipe 51 is in a communicative non-watertight state.SELECTED DRAWING: Figure 3
【課題】排水流路において、非可撓性排水管と可撓性排水管とを管継手により接続し、前記各排水管が管継手の上流側、下流側のいずれに接続されるときでも、管継手を共通して使用できるものとする。【解決手段】管継手１０は、一端側に非可撓性排水管が接続される第１接続口２０を設け、他端側に可撓性排水管５１が接続される第２接続口３０を設け、第２接続口３０は、可撓性排水管５１の端部が内挿される外筒３１と、外筒３１に内挿された可撓性排水管５１の端部に内挿される内筒３２と、可撓性排水管５１の凹部に係合し可撓性排水管５１を抜け止め状態とする係合部４０と、を備えた。更に、内筒３２の開口縁部に形成された排水溢れ縁３７は外筒３１の開口縁部に形成された排水溢れ縁３５よりも第２接続口３０の奥方に設けた。外筒３１と可撓性排水管５１との間は連通する非水密状態にある。【選択図】図３
