REPAIR MEMBER FOR EXISTING PIPELINE, AND DRAIN ARRANGEMENT
To enhance waterstop performance between a repair member and an existing pipeline when the existing pipeline is repaired.SOLUTION: A repair member 10 is inserted into an existing vertically-extending pipeline 60 in repairing the pipeline. The repair member 10 comprises: a vertically-extending vertical pipe 11; a seal member 20 which protrudes from the vertical pipe 11 outward in the radial direction and is elastically deformable; and a holding part 30 which protrudes from the vertical pipeline 11 outward in the radial direction above the seal member 20, has a protruding length L3 that is shorter than the protruding length L1 of the seal member 20 from the vertical pipe 11, and holds down part of the seal member 20 downward in the case where the seal member 20 warps upward. The seal member 20 comprises a first part 21 that is arranged above the depressing part 30 and a second part 22 that is arranged between the holding part 30 and the existing pipeline 60 when the vertical pipe 11 is inserted into the existing pipeline 60. The thickness T1 of the first part 21 is greater than the thickness T2 of the second part 22.SELECTED DRAWING: Figure 7
【課題】既設管路を補修したとき、補修部材と既設管路の間の止水性を高める。【解決手段】補修部材１０は、補修する際、上下に延びた既設管路６０内に挿入される。補修部材１０は、上下に延びた立管１１と、立管１１から径方向の外方に突出し、弾性変形可能なシーリング部材２０と、シーリング部材２０の上方において、立管１１から径方向の外方に突出し、突出長さＬ３がシーリング部材２０における立管１１からの突出長さＬ１よりも短く、シーリング部材２０が上向きに撓んだときにシーリング部材２０の一部を下向きに押える押え部３０と、を備える。立管１１が既設管路６０に挿入されたとき、シーリング部材２０は、押え部３０よりも上方に配置される第１部分２１と、押え部３０と既設管路６０との間に配置される第２部分２２と、を有する。第１部分２１の厚みＴ１は、第２部分２２の厚みＴ２よりも厚い。【選択図】図７
