<p>PROBLEM TO BE SOLVED: To prevent a disadvantage at transport time and execution work time, and excellently absorb vibration in the pipe axial direction while easily and quickly connecting underground buried pipes. SOLUTION: One end of an underground buried pipe 2 where seal members 5 are attached to both end part outside surfaces is inserted into the loose end part of a fixing side connecting pipe 4 where one end is connected to the connecting part 1 of a hand hole and a manhole, and as a joint for connecting the other end of this underground buried pipe 2 to one end of the other underground buried pipe 2 where the seal members 5 are fitted around both end part outside surfaces, the inserting parts 3A (3) for inserting the end part of the underground buried pipe 2 are respectively provided on the tube axis directional longitudinal both sides, and a joint 3 having in the tube axis directional central part the abutting part 3B for regulating an inserting quantity of the underground buried pipe 2 to the respective inserting parts 3A is used. The end part of the underground buried pipe is inserted into the inserting parts 3A of this joint 3 up to a position abutting to the abutting part 3B to connect the underground buried pipes 2, 2 to each other.</p> |
