PROBLEM TO BE SOLVED: To provide a method for regenerating the deteriorated part of a sewer pipe without generating a damage even if a curved part small in diameter is regenerated. SOLUTION: Curved part regenerating members divided into a size passing through a manhole are assembled at a predetermined position of an existing pipe 7 by a H-shaped joiner 3 and the assembled regenerating members are bonded by welding or the like to obtain a regenerating pipe of a curved part and this regenerating pipe and a regenerating pipe of a straight part formed by spirally winding a long strip material having joining mechanisms provided to both end edge parts thereof are joined by an in-core joint to obtain a regenerating pipe. The gap between the existing pipe 7 and the regenerating pipe is filled with mortar to compound the existing pipe 7, the mortar layer and the regenerating pipe in three layers to regenerate the existing pipe.
