THERMAL INTEGRITY PROFILER (TIP™)
Evaluation of the entire cross-section and the entire length of the deep foundation element
Measuring heat generated by curing cement to assess the quality of drilled shafts/bored piles, augered cast in place (ACIP)/continuous flight auger (CFA) or drilled displacement piles, slurry walls, barrettes, soil nails, and jet grouted columns.
Evaluates concrete quality inside and outside the reinforcing cage
Accelerates construction with tests conducted during concrete curing
Reveals necking or inclusions, bulges, variations in concrete cover, shape of shaft and cage alignment
Thermal Wire® Cables can replace access tubes
Thermal Aggregator Units (TAG) allow for real-time data review via the Cloud
DESCRIPTION
The Thermal Integrity Profiler (TIP™) uses the heat generated by curing cement to assess the quality of drilled shafts and of bored, augered cast-in-place, continuous flight augers, or drilled displacement piles. It may also be used for quality control and shape evaluation of jet grouting, slurry walls, and diaphragm walls. TIP™ evaluates the entire cross-section and the entire length of the foundation. Results are available shortly after shaft installation is concluded: TIP™ reveals necks or inclusions (regions that are colder than average), bulges (regions that are warmer than average), variations in concrete cover, and the shape of the shaft and cage alignment.
The average temperature within a concrete shaft is dependent on its diameter, the concrete mix design, and the time of measurement relative to concrete casting. Measured temperatures at the reinforcement cage vary with the distance to the center of the shaft and with the concrete cover.
The TIP™ starter system includes the TIP™ Main Unit and 12 Thermal Acquisition Ports (TAP-Edges), along with the TIP™ Reporter Software. THERMAL WIRE® cables (smart sensing cables fitted with uniformly spaced digital temperature sensors) are ordered separately depending on the length and quantity needed. The cables are tied to the rebar cage and cast into the shaft.
