Ultrasonic phased array system and concrete filled steel tube construction method
The invention discloses an ultrasonic phased array system and a steel tube concrete construction method, and the system comprises an ultrasonic probe array which comprises a plurality of array elements distributed in an array shape; the array element is a dry coupling probe and is used for exciting longitudinal waves as a detection carrier; the magnetic suction device is mounted on the ultrasonic probe array and is used for being adsorbed on the surface of a steel plate of the steel pipe, so that the dry coupling probes are uniformly coupled with the steel plate; the pulse transmitter is used for driving each array element; the signal amplifier is used for amplifying the ultrasonic signals received by the dry coupling probes; and the signal receiving module is used for receiving the ultrasonic signal amplified by the signal amplifier and transmitting the received ultrasonic signal to the data processing module through the wireless transmission module. The system is adsorbed on the surface of a steel plate by adopting the magnet during detection, so that uniform coupling between the probe and a detected medium is realized, a coupling agent does not need to be smeared, the detection speed is high, and the system can find defects in time in the pouring process of the concrete filled steel tube.
本发明公开了一种超声相控阵系统以及钢管混凝土施工方法，该系统包括：超声探头阵列，包括多个阵列状分布的阵元；阵元为干耦合探头，用于激发出纵波作为检测载体；磁吸装置，安装在超声探头阵列上，用于吸附在钢管的钢板表面，以使得各干耦合探头与钢板之间均匀耦合；脉冲发射器，用以驱动各阵元；信号放大器，用于放大各干耦合探头接收到的超声信号；信号接收模块，用于接收信号放大器放大后的超声信号，并将接收到的超声信号通过无线传输模块传输至数据处理模块。该系统在检测时采用磁体吸附于钢板表面，实现了探头与被检介质间的均匀耦合，不需要涂抹耦合剂，检测速度快，使得该系统可以在钢管混凝土浇筑过程中及时发现缺陷。
