    To provide a nondestructive inspection method and an impact elastic wave device in a narrow part of an unconventional and practical concrete structure.SOLUTION: A nondestructive inspection method in a narrow part 51 of a concrete structure 50 moves an impact elastic wave device N in the narrow part 51, performs striking by a striking part 1 when the impact elastic wave device N is moved, and receiving of an elastic wave caused by the striking by an elastic wave reception part 2. The nondestructive inspection method in the narrow part of the concrete structure confirms a defect occurrence state of an object part 52 to be inspected on the basis of the received elastic wave.SELECTED DRAWING: Figure 5

    【課題】本発明は、従来にない実用的なコンクリート構造物の狭小部における非破壊検査方法及び衝撃弾性波装置を提供することを目的とする。【解決手段】コンクリート構造物50の狭小部51における非破壊検査方法であって、前記狭小部51において、衝撃弾性波装置Ｎを移動させ、この衝撃弾性波装置Ｎの移動時に前記打撃部１による打撃と、この打撃により発生する弾性波の前記弾性波受信部２による受信を行い、この受信した前記弾性波に基づき前記被検査対象部52の欠陥発生状態を確認するコンクリート構造物の狭小部における非破壊検査方法である。【選択図】図５
