PROBLEM TO BE SOLVED: To provide a pipe assembling piece for lining work free from variation in quality in a construction management state at a construction site, and a pipe assembly for lining using the pipe assembling piece, and a lining method using the pipe assembly. SOLUTION: This pipe assembling pieces 10 respectively formed into a cylindrical body of a prescribed length having approximately circular end faces at both ends, in a state that both end faces have a prescribed angle not in parallel with each other, having a recessed portion 10c at one of the approximately circular end faces at both ends, having a projecting portion 10a of the shape fittable and connectable with the recessed portion 10c in a slidably and rotatable state at the other approximately circular end face, are connected to constitute the pipe assembly 20 for lining. Thus a bending state of the pipe assembly for lining can be changed by rotating the pipe assembling pieces to easily cope with snaking of an existing pipe, and further the quality of a completed lining pipe can be stabilized.
