Abrégé

A lining tube for restoring a defective sewer shaft has an inner film tube and a radially expandable tubular layer of fiber material impregnated with a curable reaction resin. The inner film tube has a connecting portion that connects two circumferential portions, to a circumferentially closed inner film tube with a defined nominal diameter. The connecting portion has a predetermined breaking point that can be separated in the circumferential direction by introducing a pressure medium into the inner film tube in order to radially expand the inner film tube and the layer of fibrous material beyond the nominal diameter. The tubular layer of fiber material is closed by a seam at a first end that can be introduced into a channel of the sewer shaft. The seam extends orthogonally to the longitudinal axis of the tubular layer of fiber material of the lining tube.

A lining tube for reconditioning a defective sewer pipe has an inner film tube, around which is disposed a radially expandable layer of fiber material that is impregnated with a curable reactive resin. The inner film tube has a connecting section that extends in longitudinal direction thereof and connects two circumferential portions of the inner film tube that run parallel to one another to give an inner film tube which is continuous over its circumference and has a defined nominal diameter. The connecting section has an intended fracture site that extends along the inner film tube and can be parted by introducing a pressure medium into the inner film tube in circumferential direction, in order to expand the inner film tube and the layer of fiber material disposed thereon radially beyond the nominal diameter. There is also described a method of producing and of installing such a lining tube.

A lining tube for restoring a defective sewer shaft which has a first shaft portion of a first diameter and an adjoining second shaft portion of an larger diameter. The lining tube has inner film tube and a radially expandable layer of fibrous material around the inner film tube and impregnated with a curable reactive resin. The inner film tube has a connecting portion which extends in the longitudinal direction and which connects two mutually parallel circumferential portions of the inner film tube to a circumferentially closed inner film tube. The connecting portion has a predetermined breaking point which extends along the inner film tube and can be separated in the circumferential direction by introducing a pressure medium into the inner film tube, in order to radially expand the inner film tube and the layer of fibrous material beyond their nominal diameter.

Abrégé

The invention relates to a lining tube (1) for restoring a defective sewer shaft which has a first shaft portion with a first diameter, an adjoining second shaft portion with an expanded diameter, and a berm and a channel, comprising an inner film tube (10) and a radially expandable tubular layer of fiber material (20) that is provided around the inner film tube and is impregnated with a curable reaction resin, wherein the inner film tube (10) has a connecting portion (12) which extends in the longitudinal direction thereof and which connects two circumferential portions (10a), (10b) of the inner film tube (10) that extend in parallel with one another to a circumferentially closed inner film tube (10) having a defined nominal diameter, and wherein the connecting portion (12) has a predetermined breaking point (14) that extends along the inner film tube (10) and can be separated in the circumferential direction by introducing a pressure medium into the inner film tube in order to radially expand the inner film tube (10) and the layer of fibrous material (20) provided thereon beyond the nominal diameter. The lining tube according to the invention is characterized in that the radially expandable tubular layer of fiber material (20) is closed by a seam at a first end that can be introduced into the channel of the sewer shaft (100), which seam extends orthogonally to the longitudinal axis of the tubular layer of fiber material (20) of the lining tube (1).
