摘要

PURPOSE:To easily form a sealed end part generating no leak in pipeline repairing work using a two-layer repairing material. CONSTITUTION:One end of the cylindrical repairing material 1 inserted in a pipeline 11 is sealed to form a sealed end part 14 and the other end thereof is used as a supply end part supplying hot water into the repairing material 1 and the repairing material 1 is pressed to the inner surface of the pipeline 11 by the pressure of water supplied from the supply end part to execute pipeline repairing work. In the repairing material 1 formed by piling up the outside repairing material 2 pressed to the inner surface of the pipeline 11 and the inside repairing material 3 pressed to the inner surface of the outside repairing material 2 one over the other, the sealed end part 14 is formed by fitting an end part metal fitting 15 to the end part of the repairing material 1 and first and second sleeve parts 23.24 separately holding the outside and inside repairing materials 2,3 are provided to the end part metal fitting 15.
