What is the test for a pile?
The pile test is used to assess the integrity of concrete piles and to locate any hidden defects. It is performed by moving and sensing sound, using a light hammer to hit a pile to generate sound waves, as well as as a sound measurement device such as a geophone. Sensor data is transmitted to a computer that displays the results in the graph. Reflected acoustic data, called reflective, allow measuring the length of the pile as well as the location of any breaks in the concrete. Testing the pile can be performed by testing audio echoes and frequency response, while Sonic logging is another way to test the integrity of the pile. Organizations that carry out tests for the integrity of the pile use standard ASTM-D 5882-00, 'standard test method for testing low voltage integrity for pilots'. Standard details of the correct location of motion sensors and where to hit a pile in relation to sensors.In the international instructions is one step in performing a pile test and further testing to PO is neededJudges of any abnormalities such as impedance changes due to poor concrete or pilot diameter erosion.
The length of the pile of concrete is tested, but the tester of the pile determines how long the concrete is based on the average wave speed. The sound wave speed is determined by age and concrete. Variations from one pile to another can lead to wide accuracy errors.
Using sound is the only way to test the integrity of the foundation. It is not logical physically or economically to dig the entire structure for the pile test, so that the piles present serve as a structural support. One of the sound analysis methods is Sonic Echo testing, which is used along with the data from the frequency response test. The data can be collected from a depth of about 20 to 30 times the diameter of the pile of concrete, while soil quality also plays a role in the depth to which the pile can be measured.
Sonic logging allows you to test the pilots of the workoverstate at any depth or be used with any size or pile of shape. For the test, tubes are previously cast into concrete and are filled with water for acoustic measurement. For any method used, if the integrity of the foundation is questioned, the pile is removed and is subject to load testing.
