CONFIRMATION INSPECTION METHOD OF ADHERING CORE ATTACHMENT STATE IN FEED WATER PIPE BRANCH HOLE FROM WATER DISTRIBUTION PIPE OR THE LIKE, AND ITS CONFIRMATION INSPECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To directly visually recognize, by illumination, the attachment state of a rust-preventing adhering core which is attached to a feed water pipe branch hole bored at a water distribution pipe without cutting off water in the water distribution pipe in a work site even immediately after work, and to confirm and inspect the state.;SOLUTION: A see-through view window 3 by which the inside of a bored opening 35 for boring the feed water pipe branch hole H and for attaching the adhering core C in a saddled snap tap body 20 attached with the feed water pipe P for branching and connecting the feed water pipe P from the water distribution pipe B can transparently be seen is formed at a cap-nut shaped attachment base 1 which is water-tightly attached to the bored opening 35. The see-through view window 3 is integrally molded of a transparent material in a state that a stepped engagement step 4 fit to a window opening 2 formed at the attachment base 1 from the inside of the attachment base 1 is arranged at the upper part, and an illumination support 6 reaching the bored opening 35 is arranged at the lower part. An insertion hole 7 for inserting and arranging an illumination portion (11) of an internal illumination mechanism 10 is formed at the illumination support 6. The illumination portion(11) serves as an illumination bulb or as a light introducing wire rod which introduces the illumination light of the illumination bulb arranged in a remote place.;COPYRIGHT: (C)2013,JPO&INPIT
