Concrete members, particularly mass concrete structures, have cracks on the surfaces thereof for various reasons, and in order to ensure the safety of the engineering structures, detailed investigation and measurement of the cracks are required, so that objective bases are provided for evaluation and treatment. In particular, the development depth of the cracks directly influences the quality safety and other performances of the component. The conventional crack depth detection method which is also required by relevant standard standards is mainly ultrasonic detection, and when the crack part of the structure has only one measurable surface, a single-side leveling method is generally adopted.
The single-side plane measurement method needs to perform sound time measurement on the measured part of the crack by different distance measurement according to the arrangement of measurement points across the crack and the arrangement of measurement points without crossing the crack. The sound time measurement without crossing the crack places ultrasonic T (transmitting) and R (receiving) transducers on the same side near the crack, and respectively reads sound time values with the distance between the inner edges of the two transducers equal to 100 mm, 150 mm, 200 mm and 250mm to obtain the sound speed value of the concrete. And in the cross-slit sound time measurement, T, R transducers are respectively arranged on two sides of a symmetrical axis which is the slit, sound time values are respectively read according to the distances of the transducers of 100 mm, 150 mm, 200 mm and 250mm, and the depth of the slit is calculated by combining the change of the phase of an observation ultrasonic signal and a concrete sound speed value obtained by non-cross-slit measurement.
The existing method needs a steel ruler and a marking pen to measure a good distance at a tested part of a component and mark the component for positioning a transducer, and the method is complicated to operate and has large deviation. At present some set up transducer slidable on the measuring stick, improve the convenience of operation, but when removing the transducer at every turn, all need to take up whole measuring stick and adjust the transducer, can not guarantee after the measuring stick takes place to remove that the measuring stick can accurate reset, bring the deviation for measuring result.
Disclosure of Invention
