Application:
High resolution optical borehole imaging devices are suitable for such engineering fields as engineering geology, hydrological geology, geotechnical engineering inspection and monitoring. It is suitable for various boreholes including vertical borehole, horizontal borehole, anchor cable (rod) borehole, geological borehole and concrete borehole. It can form digital borehole core sample for permanent preservation, especially suitable for the crushing zone strata where actual core samples cannot be obtained.
The specific classification is as follows:
For concrete: Conduct pile foundation boring for coring verification, observe the location and extent of cavity, cracks, segregation and other defects in concrete;
For the pipe pile: Observe the pile to see if there are anomalies or defects in it, and directly check the joints, quantitatively analyze pile quality: broken area, fracture and crack location, length, width, direction and so on;
For engineering and hydrological geology: Observe the characteristics and subtle tectonics of geological bodies in the borehole, such as stratigraphic lithology, rock structure, fault, cracks, sandwich, karst, and draw geological histogram;
For underground pipes: Observe the contents of pipeline, quantitatively analyze pipeline quality: broken area, location and length, width and direction of fracture and crack.
