Bored Piles Inspection Deep Drill Hole Monitoring Tester Ultrasonic Bored Pile Foundation Tester

The Drill Hole Monitor system consists of a weighted sensor that is lowered into the While the sensor is lowered or raised to/from the bottom of the shaft, ultrasonic signals are emanated in either two or four directions. The hole geometry is interpreted from measurements of the time it takes for the signals to travel back to the sensor as the signals are reflected off the excavation sides.

These profiles are then plotted and provide a graphical representation of the verticality and diameter over entire length of the shaft/pile. In the case of larger deviations from plumb,more accurate results on verticality and actual diameter can be obtained by post-processing the data using circle fitting procedures.
digital data are recorded for long-term retention or further analysis of the results.

Main uses
1. Detection of hole diameter, hole depth, verticality, collapse expansion and contraction position and tilt direction of bored piles;
2. Detection of underground continuous wall groove width, depth, verticality, collapse expansion and contraction position and tilt direction;
3. Detection of hole expansion effect of branch piles and expanded bottom piles;
4. Detection of sediment thickness
