CONNECTION PIPE FOR PUTTING IN AND REPLACING NEW AND OLD PIPES FOR BURIED PIPE AND CONSTRUCTION METHOD FOR PUTTING IN AND REPLACING NEW AND OLD PIPES FOR BURIED PIPE

摘要

PROBLEM TO BE SOLVED: To provide a connection pipe, by which a new pipe and an old pipe can be easily connected correspondingly to a height difference and plane positions of the new pipe and the old pipe that are different at each job site, and which can be repeatedly used.;SOLUTION: A connection pipe includes: a first connection pipe 12 connected to an end of a new pipe P2 via a first joint 11; a second joint 13 connected to an end of an old pipe P1; a second connection pipe 14 connected to the old pipe P1 via the second joint; and a third joint 15 for connecting the end of the first connection pipe and the end of the second connection pipe. The first connection pipe and the second connection pipe include bent parts 12d, 12e, 14d, 14e for connecting each of a pair of lateral pipe parts 12a, 12b, 14a, 14b along the new pipe or the old pipe, vertical pipe parts 12c, 14c provided between the lateral pipe parts, and the lateral pipe parts to both ends of the vertical pipe parts. The third joint connects the end of the first connection pipe and the end of the second connection pipe while an intersection angle between the lateral pipe part 12c of the first connection pipe and the vertical pipe part 14c of the second connection pipe is arbitrarily adjusted.;COPYRIGHT: (C)2013,JPO&INPIT
