PILE DRIVING ANALYZER® (PDA) SYSTEM
High strain dynamic load testing and pile driving monitoring system. Perform dynamic load testing on most types of deep foundations.
Low strain integrity testing by pulse echo or transient response methods.
PILE DRIVING ANALYZER
The High Strain Dynamic Testing is widely used in the lieu of the conventional static load. Additional parameters on pile driving performance and stresses on pile (both compression and tension) are measured by means of sensor attached on the pile during driving.
Automatically plotted summary of data are viewed from the screen during testing.
Quick and cost efficient test for measuring bearing capacity, skin resistant and check hammer performance.
PILE INTEGRITY TESTER
The low straining test can quickly evaluate the shaft integrity using P.I.T. collector attached to a sensitive accelerometer superimposed on top of the pile.
Low strain compressive impact waves are then generated by tapping the pile top with hammer.
When the downward travelling compression wave encounters a change in cross section or quality of concrete, it generates an upward travelling tension wave which is observed at the pile top.
