[0101] The vibration detection module is used for detecting the vibration effect of an actual vehicle on the bridge, collecting vibration data, including vibration frequency, vibration amplitude, vibration time and vibration period.

[0102] The vibration simulation module is used for restoring and simulating the vibration data collected by the vibration detection module through control mechanical vibration.

[0106] Analog prediction module is used for matching and calculating the collected multiple sets of data and experience data to predict the service life of the concrete structure.

[0107] The basic principle of the ultrasonic method for detecting the structural integrity of the pile body is that a high-frequency elastic pulse wave is excited in the concrete by an ultrasonic pulse emission source, and a high-precision receiving system is used to record the wave characteristics exhibited by the pulse wave during its propagation in the concrete. When there is a discontinuous or damaged interface in the concrete, the defect surface forms a wave impedance interface, and when the wave reaches the interface, the transmission and reflection of the wave occur, which significantly reduces the received transmission energy. When there are serious defects such as loose, honeycomb, and holes in the concrete, scattering and diffraction of the wave will occur. According to the characteristics of the initial arrival time and energy attenuation of the wave, the frequency change and the degree of wave distortion, the compactness parameters of the concrete in the test area can be obtained. By testing and recording the ultrasonic wave characteristics on different sides and at different heights, and through processing and analysis, the reference strength of the concrete in the test area and the nature, size and spatial position of the internal defects can be determined.

[0108] Before the construction of the foundation pile, a certain number of sounding pipes are pre-buried according to the size of the pile diameter as the channel for the transducer. During the test, each two sounding pipes form a group, and through water coupling, the ultrasonic pulse signal is emitted from the transducer in one sounding pipe, and the signal is received by the transducer in the other sounding pipe. The ultrasonic instrument measures the relevant parameters and collects, records and stores them. The transducer is detected from the bottom of the pile upwards in sequence, covering all cross sections.

[0109] The detection instrument and equipment adopts the ZBL-U5700 non-metal ultrasonic detector and double-hole transducer produced by Beijing Zhibolian Technology Co., Ltd.

[0110] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made in terms of structure, shape, principle, etc. according to the present application should be covered within the protection scope of the present application.
