METHOD FOR REGENERATING SEWER PIPE

PURPOSE: A regenerating method of a sewer pipe is provided to simplify the workability and to completely and effectively regenerate the sewer pipe by extruding a synthetic resin pipe. CONSTITUTION: The inside of a sewer pipe(D) is cleaned. An extruder of a synthetic resin pipe is assembled by inserting through one manhole(H1). A pulling device of a forming pipe is installed through another manhole(H2). A synthetic resin pipe of a proper size is extruded in one side of the sewer pipe and the formed pipe is pulled to the other side. Both ends of the formed pipe is cut and sealed. Filler and glue are injected to the outside of the formed pipe. Hot wind is injected and extended inside the formed pipe. The formed pipe is integrally joint and fixed in the inner wall of the sewer pipe. Thereby, the sewer pipe is regenerated easily.
