摘要
Water stop material includes water-impermeable water stop material (10, 70) having an expandable hose portion (18, 72) and a flange portion (20, 74) integrally connected to one end of the hose portion. The water stop material is disposed in first and second pipelines in such a manner that the flange portion is positioned in the first pipeline (12) and the hose portion is positioned in the second pipeline (14), and is maintained, for example, by means of a base (24, 54, 82) radially and flaringly wound therearound, in such a manner that the flange portion is in a liquid-tight contact with the inner surface of the first pipeline and the hose portion extends across the second.
