Description
Piletest’s GPC is the next generation of dynamic pile testing systems. It is designed with simplified software and higher ease of use than past systems The GPC system was started by Professor George G. Goble, the pioneer of dynamic pile analyzers. The GPC complies with ASTM D4945 – Standard Test Method for High-Strain Dynamic Testing of Deep
Foundations and Eurocode EN ISO-22477-4. To test a pile, you need to connect only two dual- purpose sensors to it. The system box can be attached to the pile under test and, via a lossless wireless communication, sends all the monitored data to your computer.
This concept makes the construction site work much easier and faster to operate.
To measure four (4) sides of a pile, two main box systems can be operated concurrently with a dual WiFi connection computer. The collected data is processed by three (3) state-of-the-art s/w packages: GPC Acquisition — For collecting the sensors data and presenting real-time driving plots GPC Review — Reporting of test results and capable of automatic signal matching N_GAPA—An Automatic Pile Analysis software for signal matching analysis. Proven to be equal to CAPWAP, and faster.
Features
Lossless Wireless Transmission:
The signal is digitized in the transmitter box. The system is wireless by design using WiFi IEEE802.11ac, which is more reliable than
Bluetooth or 2.4 GHz radio of other dynamic pile testing systems.
Cost Efficient:
The transmitter box has a wire connection (optional). It uses a low–cost standard CAT5 Ethernet cable (vs. expensive DLT cable)
reaching up to 100 meters. Digitization ensures zero signal loss on 100m cable length.
Simplicity:
Single data box for both sides of the pile.
Fast to operate:
Combination transducer, strain gauge, and accelerometer are combined on one bolt–on sensor minimizing drilling time and complexity.
Intuitive Programming:
GUI has been purpose–built to be very intuitive and easy to use with real–time plots.
