Measuring vibration sheet pile driving with AuroVibe

Sheet pile driving

Sheet pile drivers

Steel sheet piles are usually applied by means of a (high-frequency) tuning block. This application causes piling to shiver, causing vibrations that may cause damage to buildings or nuisance to building inhabitants.

The AuroVibe can monitor vibration measurements fully automatically and alert users when violations are directly registered with the set limits for damage or SBR values for annoyance.

This fully certified plug-and-play vibration meter automatically delivers daily vibration reports in pdf format.  With the new SBR Directive A, "Damage to Buildings, measurement and assessment" of force we call S-curves, the dashboard processing can directly visualize the risk of damage. These S-curves can be incorporated back into the automatic daily vibration reporting.

In the table below you will find an overview of the risk of damage to buildings due to the vibrations caused by sheet piling:

Damage class

Global risk of damage in percentage depending on vibration frequency
