Introduction
The RSM-DCT(F) Borehole TV Tester integrates cutting-edge image processing algorithms with a smart, motorized lifting system in a compact all-in-one design. Without the need for a central control unit, the system can be operated via a laptop for real-time monitoring. During video recording, it simultaneously generates panoramic unfolded views and vertical borehole diagrams. It also includes a built-in tilt measurement module to assess verticality while inspecting. Designed for applications such as pile core verification and structural defect observation, it accurately identifies cavities, cracks, segregation, and geological features—delivering efficient, clear, and professional inspection results.
APPLICATION
● Verify the core of the pile foundation; observe the position and extent of various defects in the concrete, such as voids, cracks and segregation.
● Observe various anomalies and defects of the prestressed pipe piles; check the status of joints; quantitatively analyze the quality of the pile body, such as fracture area and location, length, width and direction of the fracture and crack.
● Observe various features and subtle structures of boreholes’ geological body, such as stratigraphic lithology, rock structures, faults, fissures, interlayers and karst and catalogue geological histograms.
