Ultrasonic Testing: The Key to Accurate Pull-Out Tests in Sheet Piles
Determining the remaining service life of steel anchor rods is a critical factor for the safety of our port infrastructure. In this post, we delve deeper into the role of non-destructive ultrasonic testing in pull-out tests, a method superior to traditional visual inspections.
Why Ultrasonic?
Corrosion often starts beneath the surface, invisible to the naked eye. Ultrasonic waves penetrate the steel and accurately measure wall thickness and any internal defects. This data is indispensable for a realistic calculation of the corrosion rate and the ultimate load-bearing capacity of the anchor rod.
CUR Recommendation 214
This method seamlessly aligns with the guidelines of the CUR recommendation for inspecting anchors in hydraulic engineering structures, where accuracy and reproducibility are paramount.
The Process in Three Phases
- Preparation & Scanning: The area to be examined is cleaned. Subsequently, a grid is scanned with an ultrasonic transducer.
- Data Analysis: The measured times and echoes are converted into a detailed thickness profile, identifying weak points.
- Reporting & Advice: The findings are translated into a technical report with a prediction of the remaining service life and maintenance advice.
This advanced technique enables Ryan Rodell Geotechniek not only to determine the current condition but also to make a prognosis for the future. This allows managers of ports and quays to plan maintenance before critical problems arise, leading to significant cost savings and increased safety.
