Abstract
There is provided a plurality of support members (1) in an existing pipe (101) to form a rehabilitating pipe (102). Each support member (1) includes an arcuate plate (2) that, with a substantially semicircular cross-section, has an inner diameter corresponding to the outer diameter of the rehabilitating pipe (102), so that the arcuate plate (2) is fixed to the upper half portion of the inner surface of the existing pipe (102). The rehabilitating pipe (102) is formed by spirally winding an elongate profile strip while pressing the side edges of the profile strip together from the inside thereof to join the side edges together so that the profile strip is in contact internally with the arcuate plate (2).
