    • PROBLEM TO BE SOLVED: To provide a pipeline regeneration pipe with which necessary strength can be ensured by means of the inserted regeneration pipe itself without the necessity of grouting.SOLUTION: The regeneration pipe includes: an inner wound flexible resin layer 5d which constitutes the inner layer of a straight pipe part 5b; an outer wound flexible resin layer 5e which has been superposed on the outer surface of the inner wound flexible resin layer and constitutes the outer layer of the straight pipe part; and a ridge part 5c which has been helically formed on the outer surface of the outer wound flexible resin layer. The ridge part 5c is configured of a rigid-resin core 5g which has been helically wound and a core-covering part 5f which has been integrated with the outer wound flexible resin layer so as to surround the rigid-resin core.
    • 要解决的问题:提供一种通过插入的再生管本身可以确保必要强度的管道再生管,而不需要灌浆。 解决方案:再生管包括:构成直管部分5b的内层的内部缠绕的柔性树脂层5d; 外缠绕柔性树脂层5e,其叠合在内侧柔性树脂层的外表面上,构成直管部的外层; 以及已经螺旋形地形成在外部缠绕的柔性树脂层的外表面上的脊部5c。 脊部5c由已螺旋缠绕的刚性树脂芯5g和与外部缠绕的柔性树脂层一体化以包围刚性树脂芯的芯覆盖部5f构成。 版权所有(C)2012,JPO&INPIT
