AI Technical Summary

Technical Problem

Existing technologies cannot monitor the dynamic distribution of air bubbles during concrete pouring in real time, making it difficult to effectively remove air bubbles. This can easily lead to safety hazards such as reduced structural strength, decreased impermeability, and cracks. Furthermore, traditional vibration equipment has poor coupling with aluminum film, making it difficult to achieve targeted intervention.

Method used

By applying a high-frequency alternating current to the aluminum film system, eddy currents are induced and thermo-acoustic vibrations are generated. Combined with the piezoelectric sensing array to monitor the bubble state, the acoustic flow field is used to directionally pull the bubble, and the high-frequency alternating current parameters are dynamically adjusted to achieve directional control of the bubble.

Benefits of technology

It enables real-time dynamic monitoring and directional control of air bubbles inside concrete, avoiding aggregate segregation caused by excessive vibration, improving structural strength and impermeability, and ensuring concrete quality.

Abstract

The invention relates to the technical field of concrete bubble monitoring, in particular to an aluminum film system concrete bubble dynamic monitoring and regulating method which comprises the following steps: applying a high-frequency alternating current with a first preset parameter to an aluminum film system to induce eddy current in an aluminum film and enable the aluminum film to generate thermally induced acoustic vibration; meanwhile, an eddy current thermally induced acoustic response signal reflected by an internal interface of the concrete is obtained; based on the response signal, determining current bubble state information in the concrete, including amplitude attenuation characteristics based on the sound pressure signal, frequency spectrum characteristics based on the sound pressure signal and phase delay information; and based on the bubble state information, a regulation and control instruction of a second preset parameter is generated, the regulation and control instruction is executed to adjust the parameter of the high-frequency alternating current applied to the aluminum film system, and directional traction regulation and control are conducted on the bubbles in the concrete. According to the invention, by means of an eddy current thermally induced sound technology, dynamic distribution, including the number, the particle size, the motion trail and the like, of bubbles is captured in real time, and instantaneous changes in the pouring process can be accurately reflected.
