REPAIR MEMBER FOR EXISTING PIPELINE, DRAIN ARRANGEMENT, AND REPAIR MEMBER DESIGN METHOD
To secure the bond strength of a repair member and a filler, while reducing the cost of satin finish when an existing pipeline is repaired by using a repair member with satin finish and a filler.SOLUTION: A repair member 10 is a member that is inserted into an existing pipeline 51 to repair an existing vertically-extending pipeline 51. The repair member 10 comprises a vertically-extending vertical pipe 11, a seal member 30 which protrudes from the vertical pipe 11 outward in the radial direction and is elastically deformable, and a satin-finished area which is arranged on the outer peripheral surface of the vertical pipe 11 and applied with satin finish. The outer diameter D13 of the vertical pipe 11 is between 20 cm and 47 cm inclusive. With R as the outer diameter D13 of the vertical pipe 11, the vertical measurement D20 of the satin-finished area 20 is between 91/R and 359/R inclusive.SELECTED DRAWING: Figure 2
【課題】梨地加工が施された補修部材と充填材を使用して既設管路を補修したときに、補修部材と充填材との付着強度を確保しつつ、梨地加工の加工コストを抑えることができる。【解決手段】補修部材１０は、上下に延びた既設管路５１を補修するために既設管路５１内に挿入される部材である。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３０と、立管１１の外周面に設けられ、梨地加工が施された梨地加工領域と、を備えている。立管１１の外径Ｄ１３は、２０ｃｍ以上４７ｃｍ以下である。立管１１の外径Ｄ１３をＲとしたとき、梨地加工領域２０の上下の寸法Ｄ２０は、９１／Ｒ以上３５９／Ｒ以下である。【選択図】図２
