Abstract

The invention belongs to the technical field of nondestructive testing of rock engineering, and discloses an all-directional multi-angle acoustic testing auxiliary device which comprises a coupling medium conveyer structure and a lifting bracket, wherein the coupling medium conveyer structure is used for conveying a coupling medium between an acoustic testing probe and a hole wall; the lifting bracket is connected with the coupling medium conveyer structure and is used for adjusting the contact position of the acoustic testing probe and the hole wall; the acoustic testing probe is fixed on the coupling medium conveyer structure when acoustic testing operation is executed; the coupling medium conveyer structure is lifted through the lifting bracket until the acoustic testing probe is propped against the hole wall; and the coupling medium is conveyed to a contact area of the acoustic testing probe and the hole wall by the coupling medium conveyer structure. The invention provides an auxiliary device capable of improving the acoustic measurement reliability.

Description

technical field [0001] The invention relates to the technical field of rock engineering non-destructive testing equipment, in particular to an omnidirectional and multi-angle rock mass drilling acoustic wave testing device and an auxiliary device. Background technique [0002] With the advancement of my country's large-scale infrastructure construction and deep resource and energy mining, a series of underground rock engineering has emerged, such as traffic tunnels, underground hydropower plants, paint storage, mine roadways, etc. In order to ensure the stability of the excavation process, it is necessary to properly support the surrounding rock. Therefore, reliable acquisition of the mechanical response of the rock mass during the excavation of these projects is an important part of implementing the surrounding rock support and ensuring the safety of the project. The theory of loose ring support is a widely used theory of rock mass support at present. It designs support par...
