The application discloses a wave signal amplification stethoscope device for tunnel crack repair detection, which comprises a transmitting system and a signal amplification measuring system. The transmitting system is connected with the signal amplification system through a signal transmission line. Different initial waveforms and frequencies of incident waves are obtained by using prefabricated pneumatic bullets with different diameters, and the incident waves can be transmitted to an ultradynamic strain recorder in real time. The device releases impact load to a tunnel crack repair layer, and the impact load is reflected by the bonding surface between the concrete lining layer and the repair material, so that stress wave reflection waves continue to propagate in the medium. When the reflection waves are transmitted to the interface between the repair material layer and the stethoscope, the different wave impedances of the layers can be caused by controlling the interface density and the longitudinal wave velocity of each layer, so that the transmission signal can be amplified by several times. After being amplified through multiple interfaces, the wave signal which is easy to capture and receive is obtained, and the wave signal can be used to evaluate the quality of the tunnel crack repair after being processed.
