How to detect the integrity of foundation pile by ultrasonic method

How to detect the integrity of foundation pile by ultrasonic method

When the sound velocity, amplitude and PSD value exceed the critical abnormality or sudden change, the defect should be carefully measured.
What’s crosshole sonic logging?

What’s crosshole sonic logging?

Crosshole sonic logging refers to the method of transmitting and receiving sound waves between the embedded acoustic tubes, and testing the integrity of the pile body by actually measuring the relative changes of acoustic parameters such as sound time, fr

To Test The Integrity of Foundation Piles, Pile Integrity Test and Cross Hole Sonic Logging Test are Used Together!

To Test The Integrity of Foundation Piles, Pile Integrity Test and Cross Hole Sonic Logging Test are Used Together!

To test the integrity of foundation piles, we often do low strain pile integrity test and ultrasonic pile test, so that there is nowhere to hide the defects of the pile body.
Application of Low Strain PIT Reflected Wave Method in Pile testing

Application of Low Strain PIT Reflected Wave Method in Pile testing

The application of low-strain detection technology has greatly improved the testing efficiency of foundation piles. PIT test is to analyzes the integrity of the pile body by applying a dynamic load on the top of the pile and collecting the response signal
Why use Pile Driving Analyzer? What should the testing agency do?

Why use Pile Driving Analyzer? What should the testing agency do?

At present, there are five methods for pile foundation testing. High-strain dynamic load testing is the only testing method that can test both bearing capacity and pile integrity.
How to get a good signal by low strain PIT dynamic test

How to get a good signal by low strain PIT dynamic test

The low strain PIT testing is to use a hammer to hit the top of the pile, and receive the stress wave signal from the pile through a sensor attached to the top of the pile.
