    • A repair material and a repairing method, in which partial repair for faulty portions of a pipeline such as a sewerage pipe is surely effected in fewer working processes and in a short time. A repair material (1) is used which is composed of at least two layered cylinders with an elastic inner layer (2) held in an outer layer (3) in contracted condition. The repair material is introduced into a pipeline to be taken to a location where the pipeline should be repaired, and the outer layer is removed to cause spontaneous diametrical expansion of the inner layer for close adherence to an inner surface of the pipeline. In the case where the pipeline is small in diameter, the outer layer (3) is removed outside the pipeline and only the elastic inner layer (2) is introduced into the pipeline to be conveyed to a location where the pipeline should be repaired. Before the outer layer (3) is removed outside the pipeline the repair material is cooled to temporarily delay a diametrically enlarging speed of the inner layer. Conveyed to a location where the pipeline should be repaired, the inner layer is heated.
    • 维修材料和修理方法,其中对诸如污水管道之类的管道的错误部分的部分修理在较少的工作过程和短时间内可靠地实现。 使用由至少两层分层滚筒构成的修补材料(1),弹性内层(2)在收缩状态下保持在外层(3)中。 修复材料被引入到管道中以被带到管道被修复的位置,并且去除外层以引起内层的自发直径膨胀以紧密地附着在管道的内表面上。 在管道直径小的情况下,将外层(3)从管道外部移除,只有弹性内层(2)被引入到管道中,以被输送到管道应被修复的位置。 在将外层(3)除去在管道外面之前,将修复材料冷却以暂时延迟内层的径向扩大速度。 输送到管道应修复的位置,内层被加热。

    • A liner for pipeline repair is provided that includes an elastically deformable sleeve (22) having impermeability, a base (24,62,82,110,116,120,130,140, 150,160,172,200) having a sheet-like base portion (35,64,84,202) disposed inside the sleeve, wound into a cylindrical form, and expandable radially and fixing means (36,38,68,70,72,88,90,92,94,112,114,118,122,132,134, 136,138,142,144,146,148,152,154,158,162,164,166,168, 170,174,176,178,180,206,208) disposed in the base for maintaining the base portion in a substantially cylindrical form when the base portion is expanded radially within the sleeve. The liner is used for preventing the outflow of water from a pipeline such as a sewer pipe and/or the inflow of water into the pipeline.
