Portable non-destructive Apparatus using surface wave

摘要

PURPOSE: A portable non-destructive test apparatus using surface wave is provided to prevent the sliding or slacking of an acceleration sensor when contacting with the surface of the concrete. CONSTITUTION: An acceleration sensor(110) of a surface wave sensing unit(100) measures the response acceleration of the surface wave. A housing(120) protects the acceleration sensor. A surface contact unit(130) of the conical shape is formed on the bottom of the housing. The surface contact unit forms the measuring point of the acceleration sensor to contact with the concrete member and measures the response acceleration of the surface wave. A connecting unit(200) is connected to the surface wave sensing unit. A handle(210) is formed for the facilitating carrying is formed on a connecting member.
