摘要： There is provided an apparatus for picking up a defective portion replica that can pick up a replica with high accuracy and positively even from a surface of a structure in the water. Within a container part provided at a leading end of a replica pickup part is displaced a deformable member, such as a porous expansion member, which is excellent in adhesion with a replica and which deforms when a replica material is poured into a gap between a surface of a structure and the deformable member. The replica material from the replica material supply nozzle is poured into the gap between the surface of a structure and the porous expansion member and the replica is recovered by making use of adhesion with the porous expansion member.

摘要： An ultrasonic inspection instrument for detecting a crack and performing sizing in the depth direction of the crack. By a transmitter element array and a receiver element array included in a common sensor, focus points between focused acoustic fields are electronically scanned in a range including a location where half the sum of the transmitting angle of ultrasonic waves to an inspection-target material and the receiving angle of diffraction echoes from the inspection-target material is 30 degrees, so that a tip portion of the crack is detected from the received diffraction echoes. Thus, the detectability of the ultrasonic inspection instrument for detecting diffraction waves in a subject to be inspected and performing crack inspection is stabilized and kept high.
