METHOD OF REPAIRING EXISTING PIPE

摘要

PROBLEM TO BE SOLVED: To obtain a method of repairing an existing pipe, configured to simply and reliably eliminate a gap between an existing pipe to be repaired and a rehabilitated pipe and to ensure stable and proper installation state of the rehabilitated pipe in the existing pipe.SOLUTION: A method includes at least an intermediate member installation step of placing a deformable cylindrical intermediate member 12 to be deformed by pushing force so as to fill up a gap between a rehabilitated pipe (14 and 20) and an existing pipe 10 before a step of introducing the rehabilitated pipe in the existing pipe. The gap between the rehabilitated pipe (14 and 20) and the existing pipe 10 is filled with the cylindrical intermediate member 12 to reliably and simply eliminate the gap. The rehabilitated pipe can be installed stably without a void.
