<p>PURPOSE:To repair a branch region by lining the inner surface from the open end of the branch pipe of an existing pipe and filling the branch region of the existing pipeline with the resin supplied from the branch pipe to form a resin group in the pipeline. CONSTITUTION:A resin group is introduced from the open end of a feed pipe B in addition to the remaining resin discharged into a branch pipe A at the branch region A' to form a resin group E' in the branch pipe A to fill the branch region A'. A solenoid valve 12 is closed under these conditions, and a pressure is exerted to the resin group E' from one end of the branch pipe A by a compressed gas. Consequently, the resin group E' is moved in the branch pipe A, and the branch pipe A is lined with the resin in the vicinity of one side including the branch region A', After the compressed gas is blown through, the resin is again supplied to the branch region A' through the feed pipe B to line the region. Wasteful repairing is obviated in this way.</p> |
