JACKING PIPE WITH EARTHQUAKE-RESISTANT FUNCTION

摘要

PROBLEM TO BE SOLVED: To prevent a jacking force transmission member from entering a gap between a socket and a spigot during a jacking work in a jacking pipe with a jacking function in which the annular jacking force transmission member split into an appropriate number along the circumferential direction is tightened around the outer circumference of the spigot outside the socket. SOLUTION: The jacking force transmission member 31 has a first radial projecting part 33 in contact with an end face 29 of the socket 12 on a split portion 32 in the circumferential direction, and has a second radial projecting part 36 in contact with the end face 29 of the socket 12 at the position away in the circumferential direction from the split portion 32.
