摘要

PURPOSE: To surely prevent concrete from flowing into a buried object from a notch hole provided on the tube socket of the concrete buried object by improving a blocking cap. ;CONSTITUTION: The outer periphery of a bottomed short cylindrical cap main body 11 is formed into an adhesive surface 14, and the end face of a blocking plate section is formed into a hook surface 13 to mold the first blocking cap C₁. The cap main body 11 of the cap C₁ is thrust into the tube socket 2 of a box, and the hook surface 13 is hooked on the hook pawl 3 of the tube socket 2. The adhesive surface 14 is closely stuck to a stuck surface 6 at the back of the hook pawl 3 on the inner periphery of the tube socket 2.;COPYRIGHT: (C)1996,JPO
