更生管の位置調整用スペーサ
Document Type and Number:
Japanese Patent JP6497957
Kind Code:
B2
Abstract:
Spacer for positioning a rehabilitating pipe in an existing pipe. The positioning can be easily and appropriately performed during the existing pipe regeneration work even when the space is narrow between the outer circumference of the rehabilitating pipe and the inner wall surface of the existing pipe. The spacer can be utilized as a guide.
The spacer (50) for positioning a rehabilitating pipe has an elongated shape with both end portions in a longitudinal direction cut off at an angle. The spacer (50) has a transverse width increasing gradually in a thickness direction from an upper surface portion (51) to a bottom surface portion (52) and a space (55) formed in the bottom surface portion (52) to correspond to a shape of the upper surface portion (51), thereby allowing a plurality of the spacers (50) to be stacked on one another in the thickness direction.
