PDI Cross-Hole Analyzer CHAMP-Q

Model:PDI CHAMP-Q
Country of Origin:USA
Use:The Cross-Hole Analyzer determines the quality and consistency of the concrete of drilled shafts, slurry walls, bored piles, cast-in-situ piles and other types of concrete foundations. It may be used for crosshole sonic logging (CSL) of drilled shafts or single hole sonic logging (SSL) of smaller augered cast-in-place piles.

The Cross-Hole Analyzer determines the quality and consistency of the concrete of drilled shafts, slurry walls, bored piles, cast-in-situ piles and other types of concrete foundations. PDI’s Cross-Hole Analyzer (CHAMP-Q) is ideal for testing four probes (six profiles) in just one pull, saving time and money. CHAMP-Q has color coded wires for easy identification of probe receiving/transmitting. The CHAMP-Q meets or exceeds the specifications of ASTM D6760 and several other crosshole sonic logging codes and standards.

Test the entire shaft with CHAMP-Q
Once a shaft is prepared with PVC or steel tubes during construction, transceivers are lowered into the access tubes and probe one will transmit a high frequency signal that travels through the concrete and is detected by the other probes which are acting as receivers. This action is repeated with the other probes being automatically configured as transmitters sequentially allowing up to six profiles to be scanned with a single pull. As these sensors are raised and/or lowered along the length of the foundation, the CHAMP-Q displays and records the strength of the received signal, as well as the time from signal emission to signal arrival as a function of depth.

In CSL testing, scanning various tube combinations for the entire shaft allows evaluation of concrete quality and defect location along the length and by quadrant. With the CHAMP-Q, the user can pull four cables at once, each color coded for easy identification, and via a newly designed, space efficient tri-pod.

The CHAMP-Q Tablet is portable, light and rugged featuring:

  • Fast and accurate field measurements
  • Large sun light readable color LCD touch screen that is highly visible in all lighting conditions.
    • Optimized data entry for real time analysis onsite (waterfall diagram)
    •  Replaceable battery and USB ports for quick and easy data transfer

CHAMP’s CHA-W Data Processing Software provides powerful tools for data analysis such as:

  • Ability to simultaneously review six data profiles
  • History mapping of already collected data
  • First Arrival Time (FAT) detection
  • Easy defect identification
  • Two methods of signal strength evaluation (energy or amplitude)

CHA-W reporting tools comprise of user customized graphs and tables:

  • Sonic Map – Signal strength versus time and depth in traditional waterfall diagram
  • First Arrival Time – Signal travel time from transmitter to receiver, versus depth
  • Wave-speed Plot – Wave-speed (an indicator of concrete strength) versus depth
  • Wave–speed Table – Wave-speeds, means and standard deviations
  • Energy or Amplitude Plot – Signal strength versus depth
  • Defect location graphically (horizontal redline) and in table format
