    BOLT-Tester - Nitto Construction Inc.

    BTS(BOLT-Tester) is developed in 2012 after the collapse at SASAGO Tunnel on the Chuo Expressway in Japan. Visual inspection and hammer sound testing are main inspection methods for maintenance and management of anchor bolts in a tunnel. However, these methods have some issues in regard to objectivity and reliability of the results. Pull out testing is also one of a testing method for the soundness test of anchor bolts, however, this method have also some issues in regard to cost and time, and there is a risk to damage the anchor bolt. BTS is simple and cost effective non-destructive testing equipment that solves those issues. BTS measures a waveform of impact force to evaluate the soundness of anchor bolt.
