Problems solved by technology

In particular, ultrasonic tomography (CT) technology, which uses the multi-angle measurement and oblique side of the ultrasonic transmitting transducer and receiving transducer on the same section, can realize the quantitative determination of the size, shape and position of the section defect , which improves the imaging accuracy and visualization of ultrasonic nondestructive testing, but the traditional ultrasonic CT scanning technology is a two-dimensional cross-sectional scanning imaging, which cannot fully show the overall shape of the sleeve in the form of a three-dimensional cylinder. The density of the grout

Abstract

The invention discloses a three-dimensional visual detection method and device for sleeve grouting compactness. Ultrasonic opposite measurement and CT technologies are utilized; an ultrasonic transmitting matrix plate and an ultrasonic receiving matrix plate are arranged on the two sides of the to-be-measured area of the concrete structure correspondingly,the transmitting transducers and the receiving transducers are aligned one by one, matrix-type multi-transmitting and multi-receiving detection is achieved, the ultrasonic transducers do not need to be frequently moved in the detection process, the detection efficiency is greatly improved; meanwhile, due to the fact that the matrix-type ultrasonic transducer installation mode is adopted, a very visual grouting sleeve compactness three-dimensional image can be formed, and the accuracy and the readability of the detection result are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of building quality inspection, and more specifically relates to a method and device for detecting the compactness of sleeve grouting based on ultrasonic CT technology and utilizing ultrasonic transducers arranged in a matrix. Background technique [0002] Prefabricated concrete structures have been rapidly promoted and used in China in recent years because of their high degree of industrialization, high reliability of construction quality, high construction efficiency, energy saving and environmental protection. The "Guiding Opinions of the General Office of the State Council on Vigorously Developing Prefabricated Buildings" ((2016) No. 71) puts forward the work objectives: the three major urban agglomerations of Beijing-Tianjin-Hebei, the Yangtze River Delta, and the Pearl River Delta are the focus of promoting the development of prefabricated concrete structures The rest of the cities are actively promoti...
