The cast-in-place pile casting belongs to hidden construction, the concrete slurry belongs to a wave density ring, and the pile hole diameter is smaller. The environment can obtain stable feedback waveforms by using high-frequency mechanical wave detection. Thus, the liquid environment can be identified by the feedback of the superposition of high frequency mechanical waves in different density concrete slurries.
