Summary:In the present invention, an inspection hole (17) is formed at the longitudinal-direction lateral surface of a boiler water tube (10a), the base side of a guide pipe (16) is connected to the inspection hole (17), and a closing member (24) is continuously attached to the guide pipe (16). When the thickness of the boiler water tube (10a) is measured, the closing member (24) is detached from the guide pipe (16), an ultrasound probe (18) is inserted from the tip side of the guide pipe (16) into the boiler water tube (10a), and the ultrasound probe (18) is caused to move within the boiler water tube (10a). Dans la présente invention, un trou d'inspection (17) est formé au niveau de la surface latérale dans la direction longitudinale d'un tube d'eau de chaudière (10a), le côté de base d'une conduite de guidage (16) est raccordé au trou d'inspection (17) et un élément de fermeture (24) est fixé en continu à la conduite de guidage (16). Lorsque l'épaisseur du tube d'eau de chaudière (10a) est mesurée, l'élément de fermeture (24) est détaché de la conduite de guidage (16), une sonde ultrasonore (18) est insérée depuis le côté de pointe de la conduite de guidage (16) dans le tube d'eau de chaudière (10a) et la sonde ultrasonore (18) est amenée à se déplacer à l'intérieur du tube d'eau de chaudière (10a).
