3D Tomography

While regular (1D) CSL can only show the depth of an anomaly, tomography can help visualize its shape, size, and location. Tomography is an analysis and presentation method of captured CSL data that projects the logged results into a two-dimensional (2D) plane or three-dimensional (3D) body.

CHUM 3DT Advanatges

  • True 3D tomography (compare and see) 

  • Bonus 3D tomography generation from initial 2D data.  

  • 2D Tomography is standrad with CHUM crosshole.

  • Real-time Tomography - Only with CHUM.

​

Applications

​When a suspected problem is found in a CSL test, performing 3DT may reveal more information. 3DT visualization makes it easier to view anomalies' size and location relative to the pile. Hence, 3DT visualization can support the test engineer's decision-making process when evaluating anomalies' effect on a pile's capacity and serviceability.

It is easy to generate 3D Tomography from the CHUM standard 2D Tomography 

Reliable

  • True 3D tomography 

  • Based on three tomography algorithms.

  • Choose between FAT-based tomography (velocity), attenuation-based tomography (Energy), or a combination.

Easy to Use

  • Collect data with standard 2D CHUM tomography.

  • Get a bonus 3D presentation from Piletest (limited).

  • Purchase once you are convinced of its value.

  • It uses three tomography algorithms.

    • Real-time 2D tomography.

    • Matrix-based inversion

    • Fuzzy Logic (unique for CHUM).

  • Animated 3D tomography display.

PSI

Parallel Seismic Instrument

PSI uses the well-known Parallel Seismic method to establish the depth of existing foundations (specifically for a pile or deep foundations) where the superstructure  (i.e. existing building) precludes access to the pile heads.

CHUM

Cross Hole Ultrasonic Monitor

The CHUM uses the Crosshole Sonic Logging CSL testing method to perform high-resolution quality control of deep foundations. It is used mainly for large-size deep pile foundations, where pile integrity tester like PET is not suitable.

Pile Integrity Tester
PET is used to test the integrity of deep pile foundations. PET Uses the pulse-echo method (PEM) for pile integrity testing (PIT). A pile test starts when the pile top is struck with a hammer, and the PET accelerometer records the reflected waves, which are displayed as a reflectogram.
