Abstract

The invention relates to the technical field of geological examinations, in particular to a device for determining rock parameters based on elastic waves. The device comprises a hammer body, a sensor, a piezoelectric transducer and an AD (analog-to-digital) converter. The invention provides the device for determining the rock parameters based on the elastic waves, the device utilizes a piezoelectric hammer head to stimulate the elastic waves, and can detect pores and physical parameters of field rock masses, and distinguish weathering degrees or rocks by processing and analyzing collected elastic waves, thereby greatly reducing the workload of field workers, improving the accuracy of field detection, improving the work efficiency greatly, and being especially suitable for distinguishing and detecting rock parameters in field work.

Description

technical field [0001] The invention relates to the technical field of geological survey, in particular to a device for determining rock parameters based on elastic waves. Background technique [0002] Elastic waves are waves formed by the tiny vibrations of material particles propagating in solid materials. They were also called "mechanical waves", "stress waves", and "seismic waves". Because the deformation is small and the object is in an elastic state, it is called an elastic wave; elastic waves include: shock elastic waves, ultrasonic waves, and sound waves. [0003] After knocking on the surface of rock mass, the knocking part and its vicinity will vibrate. At the same time, the vibration will spread around in the form of elastic waves, that is, shock elastic waves are formed. Ultrasound can be regarded as a special case of shock elastic waves. [0004] Shock elastic waves generated by hammering belong to non-destructive testing technology, also known as non-destruc...
