NONDESTRUCTIVE INSPECTION METHOD AND NONDESTRUCTIVE INSPECTION DEVICE
To provide a nondestructive inspection method and a nondestructive inspection device capable of quickly and easily performing a wide range of inspections such as a deck slab of a bridge.SOLUTION: A nondestructive inspection method that detects damage to an inspection target by magnetizing the inspection target from the outside of a concrete structure in which the inspection target is buried and then measuring a magnetic flux density outside the concrete structure, wherein the concrete structure is a structure on which an inspection vehicle 2 can run on an upper surface. The nondestructive inspection method includes: installing a magnetization unit 10 and a magnetic flux measurement unit 20 in the inspection vehicle 2 so that the magnetization unit 10 that magnetizes the inspection target is located in front of the inspection vehicle 2 in a traveling direction, and the magnetic flux measurement unit 20 that measures the magnetic flux density is located at the same position as the magnetization unit 10 or behind the magnetization unit 10; and measuring the magnetic flux density by the magnetic flux measurement unit 20 while moving the inspection vehicle 2 in which the magnetization unit 10 and the magnetic flux measurement unit 20 are installed along the upper surface of the concrete structure.SELECTED DRAWING: Figure 1
【課題】橋梁の床版等のように広範囲の検査を迅速かつ簡単に実施できる非破壊検査方法および非破壊検査装置を提供する。【解決手段】検査対象が埋設されたコンクリート構造物の外側から検査対象を磁化させた後、コンクリート構造物の外側の磁束密度を測定することで、検査対象の損傷を検出する非破壊検査方法であって、コンクリート構造物がその上面を検査車両２が走行できる構造物であり、検査車両２の走行方向の前方に検査対象を磁化させる磁化部１０が位置し、磁化部１０と同じ位置または磁化部１０よりも後方に磁束密度を測定する磁束測定部２０が位置するように、磁化部１０および磁束測定部２０を検査車両２に設置し、磁化部１０および磁束測定部２０が設置された検査車両２をコンクリート構造物の上面に沿って移動させながら、磁束測定部２０によって磁束密度を測定する。【選択図】図１
