Product Description
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
