Pile Testing Operation Steps and Example Analysis

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?

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

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?

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

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.

What is Overcast Control? How to effectively control the Overcast height of cast-in-place piles?

What is concrete overcast? What are the problems caused by overcast?

Analysis of 9 common problems of pipeline robots

Before asking for assistance, the user can refer to this sheet first, and it may help you to find the solution.

Pipeline Inspection and Evaluation Result Table

Functional Evaluation of Pipeline

The calculation formula of pipeline operating parameter is similar to that of damage parameter, and it is just needed to substitute n as the number of functional defects of the pipeline.

CSL Testing Data analysis

Ultrasonic is a kind of elastic wave. The concrete medium is regarded as an elastic body. The propagation of ultrasonic waves in concrete obeys the law of elastic wave propagation.

Ultrasonic cross hole testing method of pile foundation integrity

After the foundation pile is used to make holes and before the concrete is poured, embed a number of sonic logging pipes in the pile as the channels for the acoustic wave transmitting and receiving transducers.

Application Method and Description of Parallel Seismic Test

In the process of pile foundation inspection, besides the conventional underground pile foundation, it is sometimes necessary to inspect the length and integrity of foundation piles in deep foundation, foundation piles under bridge piers and existing buil
