<p>A pipe liner installation apparatus (10) for installing a flexible liner (60) into an internal connecting region between a main pipe (12) and a target branch pipe (13) is disclosed. The apparatus (10), suitable for use in repair of underground sewer pipes, is deployable from within the main pipe (12). The apparatus (10) includes: an elongate body (14); a flexible lateral arm (15) having a proximal and a distal end, the proximal end of the arm connected to the body (14); a guide means (17) connected to the distal end of the arm, the guide means (17) having a proximal end connected the to distal end of the lateral arm (15) and a free end; and an inflatable sleeve assembly (18) extending at least partially over the body (14) and the arm (15). In use, the free end of the guide means (17), or "launcher" provides a lead-in for the distal end of the lateral arm (15) into the target branch pipe (13) solely under the external action of pushing or pulling of the body (14) longitudinally with respect to the main pipe (12).</p> |
