Allnamics has monitored the pile installation process, recording the hammer blows during pile driving (PDA). Sensors for strain and acceleration were mounted on the inside of the monopiles. No WiFi or cable connection with the sensors is possible from inside the pile to a monitoring computer on deck. Consequently, the Allnamics PDR data acquisition system has been set in the ‘data recorder mode’ (stand-alone monitoring). The response to every hammer blow was stored in the internal data memory, ready to transfer the data to the PC after collecting the PDR from the installed pile.
Pile test ‘SONATE’
Preliminary piles were tested for the foundation of a new building, ‘Sonate Adagio’, in the center of The Hague, The Netherlands. The so-called HEKBuisPiles were tested with Allnamics’ StatRapid device in line with the new Dutch code NPR7201.
EXPERTS IN FOUNDATIONS
Installation monitoring PDA & VDA
Allnamics develops a wide range of testing equipment. Including the PDR, the data acquisition unit for pile monitoring. During installation or testing, the multipurpose PDR stores all signals on the internal memory and send the signals and test results wireless via powerful WiFi to a monitoring laptop. By connecting multiple PDRs, the number of monitoring channels is almost endless. The PDR is ready for monitoring during impact driving (PDA) and installation by applying a vibratory hammer, VDA.
Pile Load Testing
Allnamics is all about pile testing. With a wide range of testing techniques, Allnamics can test any type of pile on its integrity, bearing capacity, and stiffness. In addition, the founders of Allnamics have been pioneers in the field of pile testing. They have been significant contributors to the development of various pile testing methods, especially Sonic Integrity Testing, Dynamic Load Testing, and Rapid Load Testing.
Driveability Studies for impact and vibratory driving
Pile Driving Predictions are performed to predict the pile, soil, and piling hammer behavior during the installation of foundation piles, including the large diameter monopiles for Offshore Wind Farms (OWF). Allnamics is capable of performing these studies, or Allnamics can deliver its in-house developed AllWave software and train you and your staff to perform driveability studies. For both impact and vibratory driving.
Sonic Integrity Testing (SIT / PIT)
From the inventors of the Low Strain Dynamic Testing, to determine the integrity of piles. Allnamics engineers developed their first SIT equipment back in the 1960s. Based on experience in designing equipment, performing tests, and interpreting test results, Allnamics has developed a state-of-the-art Pile Integrity Testing monitoring system.
