PROBLEM TO BE SOLVED: To provide a spacer for position alignment of a regeneration pipe, capable of easily and properly performing position alignment of a regeneration pipe in an existing pipe in existing pipe regeneration construction in a short time, even when a gap between the outer periphery of the regeneration pipe and the inner wall of the existing pipe is narrow, and capable of being used as a guide in assembling the regeneration pipe in the existing pipe.SOLUTION: A spacer 50 for position alignment of a regeneration pipe has such a long shape that both end parts in a longitudinal direction are cut inclinedly, and in order to laminate a plurality of spacers in a thickness direction, a width in a short side direction is made gradually widened from an upper surface part 51 toward a bottom surface part 52, and a space 55 suitable for the shape of the upper part 51 is formed in the bottom surface part 52.SELECTED DRAWING: Figure 6 |
