Title:

POSITIONING IMPLEMENT FOR IN-MANHOLE SUB-PIPE JOINT

Document Type and Number:

Japanese Patent JP3799349

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To easily identify a position to mount an in-manhole sub-pipe joint body in a sewage inflow hole of an inner peripheral wall surface of a manhole.
SOLUTION: The sewage inflow hole is opened in a saddle part of the in-manhole sub-pipe joint body, and a sub-pipe connecting part, which communicates with the sewage inflow hole, is opened at a lower end. A centering opening 27, whose center corresponds to that of the sewage inflow hole opened in the inner peripheral wall surface of the manhole, is formed in a positioning implement 25 for aligning a position to fix the saddle part of the in-manhole sub-pipe joint body to the inner peripheral wall surface of the manhole. A positioning hole 30 is provided in a drilled state in a position to correspond to an insertion hole of a fixing member which is formed in the saddle part of the in-manhole sub-pipe joint body.
