<p>PROBLEM TO BE SOLVED: To provide a pipeline repairing equipment for making a flange part come closely contact with the main pipe inside wall of an opening periphery in the regenerating method of a branch pipe with a flanged repair material. SOLUTION: The pipeline repairing equipment 10 is provided with a press plate 11 for pressing the flange part 4 on the periphery part 7 of the main pipe opening part (opening part 6) when regenerating the branch pipe 2 by the flanged repair material provided with a flexible repair material 3 and the flange part 4 formed near an end of the flexible repair material 3. The press plate 11 is provided with supporting parts 16, 27 for supporting the press part 11, straddling the opening part 6, and packers 14, 14 which are arranged in the longitudinal direction of the pipe at both sides of the opening part 6 near the supporting parts 16, 27 and secured expendably in the radial direction respectively, and in the state where the packer 14 is contracted, the press plate can be located at the opening part 6 in the state where the packer 14 is expanded, and the press plate 11 is made the flange part 4 come closely into contact with the periphery part 7 by making the packer 14 expand in the radial direction of the supporting part 27.</p> |
