Abstract: An apparatus for everting and inserting a pipe-lining material to rehabilitate an underground pipeline comprises an everting nozzle that is disposed so that an opening thereof faces an opening of the pipeline. The pipe-lining material is brought un-everted up to the everting nozzle and attached to the nozzle opening thereof and fluid pressure is applied inside the pipe-lining material to evert and insert it in the pipe-extending direction of the pipeline to be rehabilitated.

Abstract: A pipe lining material comprising an inner lining material and an outer lining material is used to rehabilitate an aged existing pipe. The inner lining material and the outer lining material are made of a tubular resin-absorbent material that is impregnated with a photo-curing resin and a thermosetting resin. The resin-absorbent material of the inner lining material has a higher density than that of the outer lining material. The photo-curing resin of the inner and outer lining materials is cured by light when the pipe lining material is irradiated with light, and the heat generated when the photo-curing resin is cured cures the thermosetting resin of the inner and outer lining materials. Since the resin-absorbent material of the inner lining material has a high density, voids are less readily formed. Even if voids are generated in the resin-absorbent material of the outer lining material, the voids will be covered by the inner lining material having fewer voids.

Abstract: A method for lining a pipe conduit with a coated textile tubing that adheres to the inner walls of the pipe conduit by means of an adhesive. The coated textile tubing can be filled with a long pot life adhesive and the textile tubing turned inside out (inverted) while being introduced into the pipe conduit. A fast curing adhesive is substantially simultaneously applied to the inner wall of the pipe conduit in as short a distance as possible to the moving tubing inversion point.

Alternatively, an impregnated textile tubing can be substituted for the tubing filled with the long pot life adhesive. As a further alternative, conditions are controlled to cause curing of the adhesive only in the inverted portion of the tubing.
