Method for rehabilitating existing pipe and support member for rehabilitating pipe

摘要

Inside an existing pipe (101), multiple support members (1) are set to form a rehabilitating pipe (102). The support members (1) are provided with an arc-shaped plate (2) that has a roughly semicircular cross-section with an internal diameter corresponding to the external diameter of the rehabilitating pipe (102). Said arc-shaped plate (2) is fixed to the upper half of the internal surface of the existing pipe (102). The rehabilitating pipe (102) is formed by winding a long band-shaped member helically while pressing the side edges of the band-shaped member together from the inside to bond same to each other, the band-shaped member making contact internally with the arc-shaped plate (2).
