摘要： PROBLEM TO BE SOLVED: To provide an active pipe branching joint capable of preventing a resilience keeping ring from slipping off into the joint by structuring so that a missing part of the resilience keeping ring precludes touching with a cutting scrap receptacle tray at the time of pulling up and by installing a new stopper plate to prevent the resilience keeping ring from slipping off from a groove. SOLUTION: The resilience keeping ring 52 has recessed parts 52d and 52e at the inner surfaces of the mutually confronting ends 52b and 52c in the missing part 52a. The stopper plate 60 is installed in the recessed parts 52d and 52e in such a way as covering the missing part 52a and is coupled rigidly with the tip of a set screw 61 screwed into one part of the circumferential wall 11b of a boring operation hole 14.

摘要： PROBLEM TO BE SOLVED: To improve assurance and reliability of decision on an inspection result of airtightness of a main plug to close a boring control port after take-out of chips, in a joint for active pipe branch wherein chips are stored in a chip tray after boring of an original pipe by a hole saw, and then taken out. SOLUTION: A pair of first and second division joints 4 and 5 are conjugated with a part in an axial direction of an original pipe 1 and a branch pipe 2 is connected to a branch pipe connection port 13 of the second division joint 5. The chip tray 15 in which chips 42 generated due to boring 40 by the hole saw are stored is lifted until it is fitted in the internal part of a seal ring 21 and a boring control port 14 is temporarily closed in an airtight state. When, after the chips 42 are recovered under an airtight state, an original plug 45 is fastened against the boring control port 14, the chip tray 15 in a seal ring 21 is pressed down to a position above an elastic ring 52 by a tray pressing down member 56. Thus, airtightness by the chip tray 15 through fastening effected by the original plug 45 is reliably released and decision on a result of original airtightness inspection of the original plug 45 is reliably made.
