The internal defect of the concrete refers to hidden defects such as cellular unclamping or hollowness and the like formed in the concrete due to vibration leakage, slurry leakage or stone overhead on a steel reinforcement framework in the construction process of the concrete structure. The defect is obviously developed due to the fact that the inside is not compact and is easy to be corroded by the environment, and the bearing performance of the structure is reduced.
The existing method for detecting the internal defects of the concrete comprises the following steps: firstly, roughly measuring the approximate position of the internal defect of the concrete according to the site construction record and the appearance quality condition, and then finely measuring the suspicious region according to the roughly measured condition. In the fine measurement, the structure to be measured is often required to have one or two pairs of test surfaces parallel to each other, and the test process comprises a flat measurement method, a opposite measurement method and an inclined measurement method, wherein the opposite measurement method is most commonly used and has higher test precision, and a group of (two) transducers are respectively arranged on the surfaces parallel to each other and are positioned at the same position relative to the test surfaces, so that ultrasonic signals can be transmitted in a straight line, signal attenuation is reduced, and the detection precision is improved. And analyzing whether the concrete has quality defects or not by collecting ultrasonic signals, and finally determining the distribution range of the internal defects by carrying out fine measurement on a plurality of measuring points.
Aiming at the related technology, the applicant finds that whether the transducer can be positioned at the same position of the test surface in the fine measurement process can influence the transmission path of the ultrasonic signal; when the deviation of the measuring point is large under the condition of opposite measurement, signal attenuation is caused, the influence on the detection result is large, the precision of the test result can be greatly reduced, in addition, in order to ensure the accurate positioning of the transducer, the site can always pass through a ruler measuring method, but because the test surface is two opposite surfaces of the concrete wall, the two surfaces need to be manually measured respectively, and the site test efficiency is reduced, so that improvement is needed.
