摘要: A method for renovating a sewer manhole includes: a. pulling an inflatable film sleeve onto a mold corresponding to the sewer manhole profile; b. wrapping and/or laying an extensible textile strip of the film sleeve onto the mold, a non-extensible high-tensile-strength longitudinal strip also being laid in an axial direction between the strips; c. attaching a protective sheath enclosing the liner manufactured in this manner; d. pulling the liner off the mold that has been reduced in a radial direction; e. inserting the liner into a sewer manhole to be renovated, and introducing a pressure-tight bag into the inner film sleeve of the liner; f. sealing the liner at the upper end and inflating until it abuts against the manhole wall; g. curing the resin-impregnated liner. A variable mold, which is assembled from modules of different shapes and sizes corresponding to the sewer manhole, serves for manufacture of the liner.
