<p>PROBLEM TO BE SOLVED: To effectively utilize displacement absorption amount originally included in a flexible pipe as countermeasures for ground subsidence and earthquake.SOLUTION: A conduit connection device is provided which includes a first flexible pipe 11 and the second flexible pipe 21, and a connecting pipe 31 for connecting the first flexible pipe 11 with the second flexible pipe 21. At least one of the first flexible pipe 11 and the second flexible pipe 21 includes sleeve pipes 14, 24 having convex spherical parts 13, 23 at one end, and sheathing pipes 16, 26 having concave spherical parts 15, 25 slidably supporting the convex spherical parts 13, 23. A pipe axis of the first flexible pipe 11 and a pipe axis of the second flexible pipe 21 are deviated from each other, and the connecting pipe 31 connects the first flexible pipe 11 with the second flexible pipe 21 while a pipe axis of the connecting pipe 31 is inclined in respect to the pipe axes of the first and second flexible pipes 11, 21.</p> |
