摘要： PROBLEM TO BE SOLVED: To obtain a method for mounting a sensor element to a concrete structure and a method for properly inspecting quality of a concrete structure for existing concrete structures.
SOLUTION: A rodlike reinforcement 7 with sensor elements 10A, 10B, 10C mounted thereon, in which electrical energy and mechanical energy are convertibly converted, is previously prepared, and the reinforcement 7 with the sensor elements 10A, 10B, 10C mounted thereon is inserted into a small diameter hole 5 that is bored into an existing concrete structure 3 and thereafter the small diameter hole 5 is filled with a filler 3a. Mechanical vibration, in the condition that an oscillator 11 is brought into contact with the outside surface of the concrete structure 3, is generated by applying an oscillating signal to the oscillator 11. With this mechanical vibration, an elastic wave propagating in the concrete is detected by the sensor elements 10A, 10B, 10C, as a received vibration signal. The quality of the concrete structure 3 is inspected by calculating the propagation speed of the elastic wave from the phase difference between the oscillated signal and the received vibration signal determined in that case.

摘要： PROBLEM TO BE SOLVED: To appropriately and accurately measure a void volume according to the conditions of objects to be measured.
SOLUTION: A plurality of measuring modes are prepared according to the illuminance, luminosity, state of dryness and wetness, and state of irregularities of a position of laser irradiation to perform preliminary measurements at a desired number of points of measurement (S3-3). A superior measuring mode is selected among the plurality of measuring modes on the basis of results of the preliminary measurements to perform principal measurements (S3-5). When measurements in the selected measuring mode can not have been performed, the time required for measurement is gradually lengthened to perform measurements again (S3-11). When measurement data can not have been acquired even if the time required for measurement has reached an upper limit, measurements are performed at the points of measurement during the time required for measurements of the upper limit again (S3-12). When the number of times of measurements has reached a predetermined upper limit, measurements at the points of measurement are halted to shift to measurements at the next points of measurement (S3-9).

摘要： PROBLEM TO BE SOLVED: To provide a concrete structure quality inspection method and a concrete structure quality inspection device, which inspects "covering thickness" even if a magnetic body is included in concrete, and also inspects highly accurately a concrete strength without being influenced by the shape of the concrete structure or by mutual reinforcements.
SOLUTION: A propagation velocity is determined based on a phase difference between an oscillation signal applied to a sensor element 10A and a reception signal acquired by receiving the oscillation signal by a sensor element 10B, and on a distance between each sensor element 10A, 10B. The 'covering thickness' is determined from a phase difference between an oscillation signal applied to an oscillation element 11 and a reception signal acquired by receiving the oscillation signal by a sensor element 10C, and the propagation velocity. A concrete 21 temperature is detected by temperature sensor elements 106 provided on each sensor element 10A-10C, and the concrete 21 strength is estimated from an integrated temperature value acquired by integrating the temperature at every fixed time.
