PILE INSTALLATION RECORDER (PIR-Q)
An Automated Monitoring Equipment that assists in the installation of augered cast-in-place (ACIP)/continuous flight auger (CFA) and drilled displacement piles by displaying pumped grout/concrete as a function of depth in real time.
Records and displays accurately measured, pumped grout volume and auger depth in real time, optionally with grout pressure or torque measurements and RPM
Installation log results printed immediately on a small field printer
Data collection can be monitored remotely in real-time
May be installed in any type of dedicated or general purpose drilling rig equipment
Can be used in low headroom applications
The PIR-Q is an Automated Monitoring Equipment that assists in the correct installation of augered cast in place (ACIP) / continuous flight auger (CFA) and drilled displacement piles by displaying target versus actual poured concrete volume in real time.
The equipment may be installed in any crane, including those operating with low headroom. As the crane proceeds from pile to pile, the operator easily monitors the installation of every pile on the job.
The key parameters for a precise installation are pumped grout volume and auger depth. The PIR-Q accurately records and displays both in real time. The equipment consists of a main unit installed in the crane cabin, a depth measurement device*, a Foxboro magnetic flow meter, a pressure transducer that gives an indication of the auger torque and an auger rotation measurement.
The PIR-Q is totally operated through the touch screen display of the main unit. Its large readouts provide useful, easy to see information to the crane operator.
Results may be printed in the form of an installation log, on a small field printer, immediately after each pile is completed. Once data is downloaded to a computer the PIR-PLOT Software performs further analysis and outputs installation and productivity reports, along with graphs of key parameters versus depth.
The Pile Installation Recorder conforms with the Federal Highway Administration Geotechnical Engineering Circular (GEC) #8 – and with the Deep Foundations Institute Augered Cast-In-Place Piles Manual.
