摘要
There is described a method and a liner for in situ renovation of a sewer manhole, e.g., a transition well, where inside the well there is inserted a prefabricated liner in the shape of a glass fiber reinforced stocking of thermosetting polyester or epoxy formed by winding, weaving or braiding externally of a unilaterally suspended mold with a diameter allowing the mold to be lowered through a manhole curb or cone, the rubber coating consisting of a detachable rubber bag that is fastened to a flange to be displaced externally on the mold, the polyester or epoxy liner being wound, woven or braided in such a way that the length/diameter ratio of the liner may subsequently be changed by changing the length/diameter ratio of the liner as the polyester or epoxy impregnated glass fibers are connected with the flange by the winding, weaving or braiding.
