PROBLEM TO BE SOLVED: To provide a position adjustment spacer for regeneration pipe in which re-adjustment of a position of a regeneration pipe within an existing pipe at the existing pipe regeneration work can be simply and appropriately carried out in a short time, and provide a position adjustment method using the spacer.SOLUTION: A spacer 50 for position adjustment for a regeneration pipe includes a first wedge-like member 51 inclined at a prescribed angle so that a deep side in an inserting direction may become high, a second wedge-like member 52 inclined at the same angle as the inclination angle of the first wedge-like member 51 and overlapped on the first wedge-like member 51 while its inclination angle surfaces being aligned, teeth 51b, 52c enabling the second wedge-like member 52 to be moved in an inserting direction in respect to the first wedge-like member 51 and causing motion of the second wedge-like member 52 in an opposite direction to the inserting direction to be engaged at a plurality of engaging positions, and a resilient deformation piece 52b for releasing the engaged state of the second wedge-like member 52 at a plurality of engaging positions.SELECTED DRAWING: Figure 10 |
