<p>PROBLEM TO BE SOLVED: To exhibit fixing force between an existing concrete and reinforcing-bars as designed by confirming that roughening treatment is surely performed.SOLUTION: A roughness state of the inner wall surface 70 of a drilled hole is confirmed by using the measuring device which includes: measuring means 20 mountable on a tip part of a core tube 160 of a drilling device 100 fixed to a concrete structure; transfer means for transferring the measuring means 20 along the longitudinal direction of the inner wall surface 70 of the drilled hole; transfer distance measuring means 41 for measuring a transfer distance of the measuring means 20; shape calculation means 42 for calculating an irregular shape of the inner wall surface 70 of the drilled hole by receiving measurement signals from the measuring means 20 and the transfer distance measuring means 41 and performing a predetermined arithmetic processing. When the roughness state is sufficiently treated, reinforcing-bars are inserted into the roughening-treated hole while a filler is injected thereinto.</p> |
