Apparatus for picking up a defective portion replica

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.
