摘要: There is provided a method of repairing an existing pipe (1), which comprises introducing at least one leading pig (3) into the existing pipe through one open end (1a) thereof, introducing behind the leading pig a necessary amount of adhesive agent (5) into the existing pipe through the same open end thereof, fixing one end of a liner tube (6) at the above open end of the existing pipe, in a manner such that the liner tube may be reversed into the existing pipe, and providing a negative pressure into the existing pipe through an opposite open end thereof to cause the leading pig (3) and the adhesive agent (5) to move forwardly and thus cause the unfixed portions of the liner tube to be reversed into the existing pipe. The adhesive agent is caused to move through the existing pipe in the form of a plug flow, thereby coating the whole internal surface of the existing pipe (1) with the adhesive agent, ensuring that the liner tube (6) reversed into the pipe may adhere to the internal surface of the existing pipe.
