WTS-DCT(D) Optical Borehole TV Tester
An HD digital camera probe is used for the WTS-DCT (D) Borehole TV Tester to carefully observe the interior of the core hole or the inner wall of the prestressed pipe pile in real-time. It is used to record and increase the image within the effective image range of the probe and save the pictures of the probe in video mode.
BIT measures the verticality of a borehole and existing piles. It uses the auger/bucket itself as the centralizer and eliminates the need for a heavy-to-move system.
The BIT ensures a fast and accurate determination of inclination in both dry and wet boreholes.
Large boreholes and diaphragm walls may be quickly tested several times during drilling to enable real-time corrective action.
The BIT Main unit is a rechargeable battery operated with wireless communication channels to the depth meter, the mobile computer, and the rig operator box. Rugged polyurethane cable connects the main unit to the inclination sensor.
Precision bi-axial inclination sensor, harsh environment, and pressure-proof to 300m, attached to the drill/bucket using a simple disposable metal plate.
Precision wireless depth meter, transmitting accurate depth to the main box.
Any Android mobile device with Bluetooth communication.
Rig operator satellite box with two LEDs.
Low-cost compared to traditional caliper systems.
Quick to test.
User-friendly wizard-driven software. No training is needed.
Works on any diameter.
Function:
Configuration:
Full Set of 98-type Optical Borehole TV Tester
Full Set of 60-type Borehole TV Tester
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.
- Observe the contents of underground pipelines; quantitatively analyze the quality of pipeline, such as fracture area and location, length, width and direction of the fracture and crack.
