Description

Intelligent identification device for tunnel rupture deformation and geological information based on borehole imaging Technical Field

[0001] The present invention relates to the technical field of geological information exploration, and in particular to a device for intelligently identifying tunnel rupture deformation and geological information based on borehole imaging. Background Art

[0002] The borehole imaging instrument is mainly composed of an imaging host, an imaging probe, a guide pulley, a push rod, a cable, a depth encoder and a tripod. By drilling the surrounding rock in the monitoring area, an imaging probe of corresponding size is selected, and the imaging probe is pushed into the surrounding rock borehole using the push rod and the hand-cranked winding reel to record the image information of the surrounding rock on the hole wall. It is mainly used to observe the rock structure characteristics inside the borehole and identify the joints, cracks and fractures of the surrounding rock on the hole wall.

[0003] Borehole imaging cameras currently lack the capabilities to identify lithology or monitor deformation of the surrounding rock mass. Imaging probes alone cannot identify changes in the rock mass's profile, making it impossible to assess the potential risk of collapse within the borehole. Furthermore, the depth encoder's accuracy in locating the joints and fissures in the surrounding rock mass is poor. The image information recorded by the borehole imaging camera must then be manually processed using software to identify joint and fissure information, including location, width, length, dip, and inclination. This can introduce a certain degree of error and consumes significant operator time and effort.
