The invention discloses a
transducer for detecting a rock
mass acoustic wave. The
transducer comprises a transmitting
transducer (1), a receiving transducer (2), a rigid connection
pipe (3), a measuring bar (4), a
hydraulic pump (8) and an
acoustic wave collecting device (9), wherein the transmitting transducer (1) is connected with the receiving transducer (2) through the rigid connection
pipe (3); the top end of the transmitting transducer (1) is connected with the measuring bar (4). The transducer has the advantages that dry hole detection of an
acoustic wave test is achieved under the condition that a
coupling agent does not need to be introduced through direct contact of a scalable hydraulic contact and hole
wall rock mass of a detection hole; the transducer is not affected by
water supply for construction, and drilling
azimuth and angle, and can adapt to various detection conditions on the scene; the
coupling pressure is controlled through
hydraulic equipment with a pressure gage, and the consistence of the
coupling conditions can be ensured. The effect of the coupling agent is removed, and the consistence of the coupling conditions is ensured, so that the data in the aspects of acoustic wave amplitude,
frequency spectrum and the like also can be obtained besides the condition that the waveform jump point can be accurately judged to obtain
acoustic wave velocity data in the acoustic wave test by using the device provided by the invention.
