PDA Testing will provide prediction on the pile bearing capacity, pile integrity, driving stresses and hammer performance for a given pile penetration. It is a relative low cost type of pile testing compared to static load test (MLT or CRP). The testing technique is quick and accurate.
PDA also can be used to perform high strain pile bearing monitoring to evaluate pile driving information for pile bearing capacity, pile integrity, driving stresses and transferred energy against pile penetration. The results are essential for the actual pile driving process and to obtain valuable data on the hammer, pile & soil system for re-design on the piled foundation (if necessary).
Technical characteristics:-
1. Original instantaneous floating-point amplification technology, large dynamic range, high signal-to-noise ratio, taking into account the undistorted collection of strong and weak signals;
2. Removable lithium battery, support charger, and additional battery can be equipped to ensure uninterrupted field work ;
3. Support bilingual operation in both Chinese and English;
4. Automatically adjust the balance of the strain bridge to reduce the influence of the initial deformation of the strain ring on the signal acquisition and eliminate the zero drift of the signal;
5. With a three-dimensional correction function for shallow defects, accurate defect positioning ;
6. Built-in Bluetooth, Wifi, with real-time monitoring wireless upload function;
7. Fast signal collection rhythm, can complete 60 hammer / minute signal collection work, real-time piling monitoring test;
8. 4 inch true color LCD display, curve Clear and intuitive, with adjustable backlight;
9. High-strength engineering plastic casing, small size, light weight, portable, and simple operation;
10. Real-time self-checking on-site sensor installation status;
11. Touch screen operation, friendly software interface, simple operation;
12. On-site analysis results of Case method, F-ZV curve, up and down wave curve;
13. Adjustable screen brightness, suitable for use under various lighting conditions;
14. Adjustable background color and curve color to meet customer needs.
