PDA High Strain Pile Dynamic Load Tester Pile Load Driving Analyzer Drilled Pile Foundations Equipment Pile Load Capacity And Pile Integrity Testing Instrument
The tester 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.
The tester 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).
Software Feature
