    • This invention relates to a laminate for lining a passage, entirely or partially surrounded by walls, on or under the ground, comprising at least one layer of a reinforcement of continuous fibres, curable resin and a plastic foil or a plastic film, which is on the inside of the laminate when this one is introduced into the passage that shall be lined, there being arranged a fabric of fibres between the inner film and the reinforcement, which fabric on its side turned to the inner film carries cut fibres, and which together with its cut fibres form a combination fabric, absorbing resin, for concentration of curable resin to the inner surface of the cured laminate. According to the invention the laminate is characterized by the fact that the fabric (6) comprises at least two layers (8-10), put together, each one of which in an inactive position having two essentially parallel side portions (A, B), and which are displaced in relation to each other in such way that in an active position, i.e. when the side portions (A, B) are laid to a ring, there is formed a joint between the one side portion (A) of the one layer (8, 9) and the other end portion (B) of the other layer (9, 10), the remaining end portions (B, A) of the two layers (8, 9; 9, 10) are positioned in that way that they cover the joint on each side, and the joint arrangement making it possible for the end portions of the layers to be able to slide in relation to each other during the installation/expansion phase.
    • 本发明涉及一种层压板,用于衬里在地面上或下面完全或部分被围墙环绕的通道,包括至少一层连续纤维,可固化树脂和塑料薄膜或塑料薄膜的增强层, 当该层压板被引入要衬里的通道中时,层压体的内部在内膜和加强件之间布置有纤维织物,该侧面上的织物向内膜转动,并带有切割的纤维,并且一起 其切割的纤维形成组合织物,吸收树脂,用于将固化树脂浓缩到固化的层压体的内表面。 根据本发明,层压体的特征在于织物(6)包括至少两层(8-10),放在一起,其中每一层位于具有两个基本上平行的侧面部分(A,B)的非活动位置, 并且相对于彼此移位,使得在活动位置,即当侧部(A,B)被放置在环上时,在所述侧部(A,B)的一侧部分(A) 一层(8,9)和另一层(9,10)的另一端部(B),两层(8,9; 9,10)的其余端部(B,A)位于 以这种方式,它们覆盖每侧的接头,并且联接布置使得层的端部能够在安装/扩展阶段期间能够相对于彼此滑动。
