<p>The present invention provides a non-destructive test apparatus which can be applied not only to a structure in dry conditions but also to a structure constructed under water or in a location to which it is difficult for a worker to gain access. The non-destructive test apparatus includes a support frame (10) which is disposed adjacent to the target structure (51) and has a vertical guide rail (11), and a vacuum box (20) which moves upwards or downwards along the guide rail of the support frame. The vacuum box is attached to the target structure and creates a vacuum therein. The non-destructive test apparatus further includes a hoist (40) which is provided on the upper end of the support frame to move the vacuum box upwards or downwards, a fastening unit (30) which fastens the support frame and the vacuum box to the target structure, and a vacuum pump which creates a vacuum in the vacuum box. The non-destructive test apparatus further includes a defect detecting unit which measures a strength of vacuum in the vacuum box to determine whether the target structure is defective, and a control unit which controls the elements.</p> |
