A sacrificial hydraulic jack is cast within the pile body. Upon application of load, the pile is separated into two sections and load is applied to both sections simultaneously and reacting against each other in two directions; upward against upper skin friction and downward against base bearing and lower friction. The data acquisition to measure bi-directional applied load(Q) vs pile displacement (D).
Perform static load test on deep foundation piles by constructing a kentledge blocks above the test pile (or anchored piles around the test pile) and incrementally loading the pile, with a hydraulic jack. This automation system is to record applied load (Q) vs pile displacement (D).
Instrument the pile using a strain gauge, a geotechnical sensor that measures strain in concrete. It detects resistance changes corresponding to applied forces, pressures,
or stresses, translating them into measurable electrical resistance variations.
Test involves applying incremental loads (Q)
to the pile using a hydraulic jack while
recording the microstrain.
Apply horizontal loads perpendicular to the pile to measure deflection caused by lateral forces. The test involves pulling piles either toward or away from each other to simulate planned lateral loading conditions.
Conduct a static load test on a single pile foundation to measure uplift movement or deformation under tensile loading. This method measures pile displacement as the pile is pulled upward from the ground using various load configurations.
Perform high strain pile load test (HS) on deep foundation piles to measure force (F) and velocity (V) signal to determine pile load capacity base on CASE method (1960s) and YLOAD method (2000s).
Perform low strain pile integrity test (LS) on deep foundation piles to determine the integrity of the pile by measuring and analysing the velocity response of the pile induced by an impact device (hand held hammer or other similar type).
Perform ultra sonic pile integrity test (US) on deep foundation piles to determine the integrity of the pile by emitting ultra sonic signal to evaluate pile integrity, continuity, and consistency of the pile material.
Perform hole profile (or shape) of a drilled bore hole (or spun pile hole) by plotting the hole profiling to verify the pile verticality (or alignment) prior to concrete placement and soil sediment thickness (or slurry cake thickness) at pile tip.
