Problems solved by technology

[0005] At present, many scholars are studying the internal defects of the grouting sleeve on the surface of the concrete. Considering the influence of the aggregate in the concrete, it is necessary to find a balance between the ultrasonic frequency and the minimum defect size that can be identified. The high-frequency ultrasonic attenuation is fast, and the ultrasonic wave canno

Abstract

The invention provides a grouting fullness detection method based on sleeve surface ultrasonic and a grouting fullness detection system based on the sleeve surface ultrasonic. The detection method comprises the following steps: forming an inspection port in a prefabricated component, wherein the inspection port can expose the outer surface of a grouting sleeve; vertically arranging a plurality ofmeasuring points on the outer surface of the grouting sleeve; arranging ultrasonic transducers integrating transmitting and receiving functions at the measuring points; judging the grouting conditioninside the grouting sleeve according to the intensity of head wave signals received by the ultrasonic transducers. According to the detection method, through formation of the inspection port, namely reservation of the inspection port or formation of the inspection port by virtue of removal of a concrete protecting layer outside the grouting sleeve, the accuracy of a detection result is improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a grouting fullness detection method and system based on sleeve surface ultrasound. Background technique [0002] Prefabricated buildings refer to the production of some or all of the components and parts of the building in the prefabricated factory, and then transported to the construction site, using reliable connection methods and installation machinery to assemble the components to form a building with design and use functions. Compared with the construction of cast-in-place structures, prefabricated structures have the advantages of convenient construction, fast project progress, little impact on the surrounding environment, and easy guarantee of the quality of building components. Prefabricated structures are widely used in industrial buildings in my country, and have been vigorously promoted and applied in civil buildings, especially residential buildings, ...
