PROBLEM TO BE SOLVED: To provide an expandable flexible pipe joint which copes with both displacement absorption and axial thrust. SOLUTION: This expandable flexible pipe joint includes a pair of reaction receiving rods constituted of the reaction receiving rod 40 (40A) for connecting a reaction pipe 20R positioned on one side with respect to a sleeve pipe 10, to a spigot tube 30L positioned on the other side, and the reaction receiving rod 40 (40A) for connecting a reaction pipe 20L positioned on the other side with respect to the sleeve pipe 10, to a spigot tube 30R positioned on the other side, has reaction receiving parts 21, 21 in a pipe end inner sides of the reaction pipes 20R, 20L, and has a plurality of the paired reaction receiving rods, and at least the one paired reaction receiving rods are connected to a rotary member 12 in the central portions of the respective reaction receiving rods. The problem is solved by the expandable flexible pipe joint. COPYRIGHT: (C)2011,JPO&INPIT |
