摘要： PROBLEM TO BE SOLVED: To smoothly insert an insertion pipe into a much-deflected existing pipe without any damage.
SOLUTION: When pushing the insertion pipe into the existing pipe, the insertion pipe is pushed into the existing pipe while adjusting pushing load wherein compression force on the insertion pipe is less than the load to plastically deform the insertion pipe and pushing speed. The insertion pipe is also pushed from the other side of the existing pipe while adjusting pulling force wherein expanding force on the insertion pipe is less than the load to plastically deform the insertion pipe and pulling speed, and accordingly, the insertion pipe is inserted into the existing pipe by pulling the insertion pipe.

摘要： PROBLEM TO BE SOLVED: To provide a joint for connecting a corrugated pipe, which need not manufacture a seal material to fit the wavy shape of the corrugated pipe, and can accurately mount the seal material on the corrugated pipe without twisting the seal material, and can show a large holding force against a force in the direction of the coming-off of the corrugated pipe.
SOLUTION: An engaging projection of a lock ring is inserted into an annular recessed portion of the corrugated pipe. The coming-off of the corrugated pipe from the joint body is prevented by the lock ring. In addition, an O-ring is brought into pressure contact with both side surfaces of the annular recessed portion by holding the O-ring in the compressed state between a spigot portion inserted into the joint body and a retainer fitted in the joint body. Further, a part of the O-ring in the neighborhood of its inside diameter is inserted into the annular recessed portion so as to prevent the coming-off of the corrugated pipe by the O-ring.
