Research Abstract

We have developed a judging method to check the existence of grout in tendon ducts. The method is based on the averaging of the multiple time-domain signals of the Impact-Echo. Father more, we have tried to improve the method of accessing inspection points on concrete walls. We have developed two types of climbing machines for vertical concrete walls. One type carries an impact echo machine. The other carries a remote visual inspection device.
