TDR2 Pile Integrity Testing System

Product code: CN645

Category: Concrete

Standards referenced in catalogue: ASTM D5882

Time and Frequency Domain System The TDR2 is a rugged and lightweight self contained pile integrity testing system. It is used for checking the integrity of concrete piled foundations The TDR2 unit uses solid state memory and is built for security of data and speed of operation. Housed in a tough ABS plastic case and using high quality waterproof connectors, the system can be used in inclement weather conditions. A handy carry pouch is supplied as standard. The user friendly menu system guides the operator rapidly and displays data in an easy to comprehend format. The TFT screen is clearly visible in bright daylight, but is also provided with a backlight for night operations if required. Data is transferred to the windows based TPAP analysis software though a USB interface. This versatile system can be used to test precast concrete, cast in place concrete and timber piles of most dimensions. Typical anomalies that may be located include shaft restraints, Overbreak, Cracks, Reductions in section and zones of poor quality concrete. The site unit can measure pile length and stiffness. Also by virtue of the force measurement, mobility is measured and can be used to assess concrete quality and pile section. Features 200+ piles can be tested per day Handheld, weighs less than 2Kg Storage for over 700 results On site analysis of pile length, section and stiffness Backlight LCD screen for working in dark environments Simulation software for analysis of pile and soil properties Impedance log for measuring changes in pile properties Instrumented Force hammer Operates > 8hrs on full charge Compliant with ASTM D5882 Software The TPAP analysis software is supplied as standard. This can tabulate the data and present all response curves for reporting. The Simulation module is used to produce a theoretical curve using a pile soil model. This can be compared directly with real results to aid analysis. An Impedance Log can also be presented for each result. This is useful for analysing more complex results, impedance being a function of pile section and proper ties, plotted against depth for an easily understood interpretation. TPAP Software The TPAP software is an easy to use platform for analysing results and producing reports. All raw data can be viewed to verify the validity of results. Piles are tabulated and automatically sorted into number order. Test results can then be accessed directly from the table. Analysis of pile length can be carried out either in the velocity or mobility views and interpretation can be confirmed by using the simulation and impedance log modules, removing subjective elements. Simulation Module: This powerful tool can be used to predict the mobility curve using soil and pile properties. It can also be used to assess piles with anomalies by using curve matching in real time. Up to 10 geotechnical layers can be input to simulate real ground conditions. Impedance Log: The pile shaft impedance is separated from soil effects and plotted
