WORK METHOD STATEMENT FOR PILE INTEGRITY TEST
SCOPE:
This document covers the method for conducting Pile integrity test to find out the quality of the pile. This test does not identify the all imperfections in a pile but provides information about continuity, defects such as cracks, necking, soil intrusion, changes in cross section and approximate pile lengths etc.
REFERENCES:
Standard operating procedure for Pile Integrity test provided by Third Party Agency.
MANPOWER & EQUIPMENTS DETAILS:
- Skilled Labour – As required
- Engineer/Technician – As required
- Pile Integrity tester
PROCEDURES of Pile Integrity Test (PIT) :
- Before conducting the test, pile shall be trimmed to cut off level or sound concrete level and loose concrete, debris with all laitance to be removed.
- The surrounding area of pile should be free from water.
- The bored cast in situ piles not to be tested before 14 days of cast.
- Start the test, giving light tap on the prepared surface of the pile by using hard rubber hammer. e. The shock will travel down into the pile and the same will be reflected back from the toe of the pile.
- This will be recorded through a suitable transducer/accelerometer in a computer disk for subsequent analysis.
- The primary shock wave which travels down the length of the pile is reflected from the toe by change in density between the concrete and the sub strata.
- If the pile has any imperfections or discontinuities within its length and the same will be found in secondary reflections during return signal.
INSPECTION & QUALITY CONTROL:
Reports shall be prepared based upon the observation made for the onward submission to the IE. Interpretation of tests/results shall be done by experienced persons who are involved these types of tests.
SAFETY:
The safety arrangements shall be made as per the safety plan and procedures.
CONCLUSION:
The Pile integrity test shall be proceeded further as per above mentioned procedures.
