摘要： PROBLEM TO BE SOLVED: To provide an insertion pipe assuring a good performance of restitution and involving a less pressure loss even if the pipe is in an existing line having a bend.
SOLUTION: The insertion pipe 10 includes a corrugated part 20 formed in a position mating with the bend 16 of the existing line 12. The corrugated part 20 is formed from a previously provided straight pipe 26 by subjecting it to a secondary processing such as a vacuum shaping or pneumatic shaping process. When the insertion pipe 10 is inserted into the existing line 12, the corrugated part 20 is arranged at the bend 16 in such a bent condition as complying with the curvature of the bend 16. In the bend 16, there is no risk that a wrinkle, buckling, etc. is generated even if a hot pressure steam is supplied for restituting a diametrically contracted part 22 formed in the position mating with a straight pipe portion 14. This allows a good performance of restitution and exerting the designed performance with no risk of generating a drop in the rate of flow etc. owing to an increase in the inside diameter. Because only the position mating with the bend is shaped corrugated, there is a less pressure loss originating from the corrugation shape.

摘要： PROBLEM TO BE SOLVED: To provide an insertion method of construction capable of preventing the outside surface of an insertion pipe from having a flaw.
SOLUTION: According to this insertion method, when the insertion pipe 12 is to be inserted, a corrugated pipe 14 is interposed between an existing line 10 and the insertion pipe 12. For example, the corrugated pipe 14 is inserted in the existing line 10, and then the insertion pipe 12 is inserted into the corrugated pipe 14. Otherwise, the corrugated pipe 14 and the insertion pipe 12 are simultaneously inserted into the existing line 10. The insertion pipe 12 will never touch the inside surface of the existing line 10. Because the touching area with the corrugated pipe 14 is small, the insertion resistance can be reduced. In case the existing line 10 has a bend 18, a diametrically contracted pipe is applied as the insertion pipe 12, followed by restitution after insertion. There is no risk that the insertion pipe has a flaw at its outside surface, and a drop in the performance can be precluded. It is possible to reduce the insertion resistance of the insertion pipe, a wire mounting tool, towing wire, etc.

摘要翻译：要解决的问题：提供一种能够防止插入管的外表面具有缺陷的结构的插入方法。解决方案：根据该插入方法，当要插入插入管12时，波纹管14插入在现有管线10和插入管12之间。例如，波纹管14插入到现有管线10，然后将插入管12插入到波纹管14中。否则，波纹管14和插入管12同时插入到现有管线10中。插入管12将不会接触现有的管线10的内表面由于与波纹管14的接触区域小，所以可以降低插入阻力。在现有管线10具有弯曲部18的情况下，将直径收缩的管作为插入管12施加，然后在插入后恢复。插入管在其外表面上不存在缺陷，并且可以排除性能下降的风险。可以降低插入管，电线安装工具，牵引线等的插入阻力。版权所有：（C）2004，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method of joining together the ends of synthetic pipes having an ultra-small wall thickness or any pipe end with a pipe fitting.
SOLUTION: A spring core 18 in a coil shape is inserted into the joining ends 14a of an inner surface fitting 14 made of synthetic resin. Each joining end 14a with the spring core 18 fitted is inserted to the joining end 10a of an insertion pipe 10 made of synthetic resin, and these ends 10a and 14a are joined together by means of hot fusion attachment. At this time of hot fusion joining, the inner surface fitting 14 is held by the spring core 18 from inside, and therefore, the inside surfaces 10b of the joining ends 10a and 14a can be contacted with the outside surface 14b by a contacting pressure required to make a fusion joining. Thereby the joining end 10a of the insertion pipe 10 having an ultra-small wall thickness can be put in hot fusion joining certainly. Because an ultra-thin pipe can be adopted as the insertion pipe used upon hot fusion joining, the rate of flow can be increased in an amount according to the small wall thickness. Because spring core is used in the join, the joint part can pass smoothly any bent part of an existing pipe owing to the flexibility of the spring core.

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.
