AXIAL COMPRESSION TEST WITH KENTLEDGE BLOCKS

​

• Universal Foundation Company conducts load tests on concrete piles once they have attained the required strength, typically after 28 days.

 

• The axial compressive load tests adhere to IS code 2911 part IV standards.

 

• A dead weight exceeding the maximum jacking force requirement by 25% is applied.

 

• Pile loading tests involve applying compression load via a hydraulic jack at the pile top.

 

• Settlement is monitored using appropriately positioned dial gauges.

 

• A Kent ledge, equipped with a suitable reaction frame, is utilized.

 

• The Kent ledge's center of gravity aligns with the pile axis, ensuring coaxial alignment with the jack's applied load.

VERTICAL LOAD TEST USING SAND PACKS

​

• The testing can be either initial or routine.

 

• The load is increased by 20% increments of the estimated safe load.

 

• Settlement readings are taken hourly for each increment until the settlement rate drops below 0.1 mm/hr.

 

• Once the ultimate load is reached, the load is gradually reduced in decrements, and the recovery is monitored until full rebound is achieved before proceeding to the next unload.

 

• Following the final unload, settlement measurements are taken for 24 hours to gauge complete elastic recovery. The shape of the load-settlement curve varies depending on the type of pile used.
