PRELIMINARY TESTING AND VIBRATION MONITORING

ABBAYE DES BÉNÉDICTINES IN URT (64)

INFRANEO WAS ENTRUSTED BY ANCHAGE BTP MONITORING THE VIBRATIONS OF THE SOUTH FACADE OF THE BENEDICTINE ABBEY IN URT TO MEASURE THE VIBRATION THRESHOLDS DURING THE ENTIRE PERIOD OF IMPLEMENTATION OF RETAINING STRUCTURES.

ESSAI PRÉALABLE ET SUIVI DES VIBRATIONS

Essai d’étalonnage vibratoire préalable afin de déterminer les seuils de vibration admissible par l’ouvrage avoisinant. Ces seuils ont été consignés dans un rapport d’essais transmis à l’équipe de maîtrise d’œuvre. Cet essai a notamment permis de déterminer une méthode de forage adaptée au site et de ne pas franchir les seuils de vibrations.

3 KEY PHASES: 

  1. Vibration calibration test preliminary in order to determine the vibration thresholds admissible by the neighboring structure. These thresholds were recorded in a test report sent to the project management team. This test made it possible to determine a drilling method adapted to the site and to avoid crossing vibration thresholds.
  2. Monitoring vibrations of existing structures over the entire period of installation of supports (installation of three-dimensional geophones on the facade). Infraneo was responsible for informing the project management team in real time in the event of vibration thresholds being exceeded to stop any activity that could cause disruption to existing structures, and to adapt working methods if necessary.
  3. Transmission of results: vibration measurements were the subject of weekly reports directly transmitted to project management.

As a hands-on player, Infraneo is with you every step of the way.
