SHAPE is a cost-effective, quality assurance testing device used for deep foundations such as drilled shafts, bored piles, slurry walls, barrettes and more to better characterise the three-dimensional profile of these and other excavated deep foundation elements.
PDI says SHAPE provides a fast, economical representation of the foundation excavation and verticality prior to placing concrete in wet conditions.
"We felt the market needed a modern and rugged device where we eliminate common points of failure such as electronic cables running from the surface to the device to provide increased accuracy and performance," said George Piscsalko, president of PDI.
SHAPE's drilling stem advancement rate is approximately 1ft per second, offering simplicity in analysis with a clean signal and 3D profile views. It is a completely wireless device, requiring no electronic cabling from the surface to the device during operation. This increases overall system reliability.
SHAPE automatically corrects for changes in wave speed with depth by measuring the wave speed at each measurement location along the length of the excavation and adjusting the radius calculation based on the measured wave speed at any depth location.
The unit samples all eight sensors simultaneously at a high rate of speed, allowing it to be quickly deployed and construction to continue at a rapid rate. The SHAPE can be operated on site or remotely with PDI's SiteLink technology.
