摘要：【課題】心出し用ゴム18を無くしてライナ20の正確な心出しを行ない得るようにする。【解決手段】受口11aの内部に挿し口13aを挿入して接合し、その挿し口13aの先端と受口の内面奥壁11bとの間に装填されたライナ20を備えた剛構造管継手である。そのライナ20は受口の内面奥壁側の端面にその奥壁11bより奥の直管状内周面11cに至る円筒状心出しガイド22を有する。ライナ20を受口11a内面に装填すれば、そのガイド22が受口内面奥壁より奥の直管状内周面11cに嵌って心出しを行なう。このため、心出し用ゴムが不要となり、また、ライナ20の装填と同時にその心出しが行なわれるため、その装填作業が極めて容易であるとともに、心出しも確実である。【選択図】図1
摘要翻译：要解决的问题：省略定心橡胶18并精确地定心衬套20.解决方案：在刚性结构的管接头中，插口13a插入并连接到插座11a的内部，衬套20是放置在插口13a的端部和插座的内表面后壁11b之间。衬套20在插座的内表面后壁侧的端面上具有圆筒形的定中心导向件22，其在后壁11b的深度侧延伸到直管状的内周面11c。当衬套20被放置在插座11a的内表面上时，引导件22在插座的内表面后壁的深度侧的直管状内周面11c上嵌合，并进行定中心。因此，可以省去定中心的橡胶，并且与衬套20的放置同时进行定心，因此，放置工作非常容易，并且可以确保定心。

摘要： PROBLEM TO BE SOLVED: To easily and securely expand a diameter of a lock ring regardless of a diameter of a pipe.SOLUTION: The lock ring 4 having a separation part 3 formed on the periphery is provided on a receiving part of a receiving pipe body 1. A diameter expanding jig 11 having a tapered part 12 on the tip is inserted into the inner periphery of the lock ring 4. Due to the insertion, both the tapered part 5 and the tapered part 12 of the inner periphery of the lock ring 4 and the diameter expanding jig 11 are brought into contact with each other to expand the diameter of the lock ring 4. After expansion of the diameter, both ends of the separation part 3 are brought into contact with a stopper 8 to draw the diameter expanding jig 11 while maintaining the expanded diameter of the lock ring 4. The outer diameter of the diameter expanding jig 11 is appropriately determined according to an inner diameter of the pipe body 1, so that the jig is applicable regardless of diameter of the pipe body 1. While the diameter of the lock ring 4 is expanded, an insertion pipe body 17 can be smoothly inserted into the receiving pipe body 1.

摘要： PROBLEM TO BE SOLVED: To secure the sufficient circulation area and reduce the insertion power of a new pipe. SOLUTION: Spheres 3 are laid down in a buried sheath pipe P' and the new pipe P is placed on the spheres 3 which are inserted into the above sheath pipe P'. The new pipe P is moved axially in the sheath pipe P' by rotating the above sphere 3 and a new pipe channel is created in the sheathe pipe P' by connecting an insertion nozzle of the new pipe P with a socket nozzle of a preceding new pipe one by one. At this time, the insertion power of the new pipe P can be reduced because the new pipe P moves in the sheathe pipe with the small resistance by rotating the sphere. Also, the diameter (size) of the sphere 3 which is placed in the sheath pipe P' becomes the gap between the sheath pipe P' and the new pipe P. Thereby, the gap between the new pipe P and the sheath pipe P' can be lessened and the sufficient circulation area can be secured by the inserted new pipe P. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：确保足够的循环面积并降低新管道的插入力。解决方案：将球体3放置在掩埋套管P'中，并且将新管P放置在插入上述护套管P'中的球体3上。新管P通过旋转上述球体3而在鞘管P'中轴向移动，并且通过将新管P的插入喷嘴与前一新的插座喷嘴相连接而在鞘管P'中形成新的管道管一个一个。此时，由于新管P通过旋转球体而以较小的阻力在鞘管中移动，所以可以减小新管P的插入力。此外，放置在鞘管P'中的球体3的直径（尺寸）成为护套管P'与新管P之间的间隙。由此，新管P与鞘管P'之间的间隙，可以减轻并且通过插入的新管道P可以确保足够的循环面积。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To actualize easy site construction and reliable expansion of a spigot during ground deformation due to earthquake or the like. SOLUTION: This jacking method is provided for inserting the spigot 1 of a pipe P into a socket 2 of a preceding pipe P, splicing them to each other, and newly constructing a pipe line in a pipe P'. This pipe joint structure is movable by a required length in a range where the spigot 1 cannot come off the socket 2 in the axial direction. A driving force transmitting material 14 is laid between a saddle flange 20 to be pressed and fixed against the outer periphery of the spigot 1 and the end of the socket 2. The driving force transmitting material 14 is strong enough to transmit driving force. The spigot 1 is therefore driven at its front end located in the middle of the movable required length. It is shrunk or crushed when great compressive force of earthquake or the like works, to allow the expansion of the spigot 1 relative to the socket 2. The flange 20 is pressed and fixed against the outer peripheral face of the spigot with the fastening force of the split faces, and so it easy to mount at a site. Desirably, the fastening force is a predetermined value or greater (with no upper limit) for good workability. COPYRIGHT: (C)2006,JPO&NCIPI
