Case Study: Vibration Monitoring during High Energy Impact Compaction

On site this week monitoring noise and vibration levels for one of our valued customers during High Energy Impact Compaction by the highly sophisticated machine you see here. 

The peak particle velocity (PPV) and associated frequency of ground motion are considered crucial parameters for establishing realistic safety criteria against vibrations generated during the compaction of the ground. 

One of the simplest and most fundamental methods of compacting soils involves the repeated dropping of weight onto the ground's surface. 

Soils are compacted by repeated, systematic application of high energy using specifically shaped heavy (non-circular) twin drum impact roller assemblies.  In this approach the primarily achieved through the collapse of the soil structure and the release of the gas phase from voids within the soil.

The dynamic compaction method has been employed to enhance the ground at a site in Faversham, Kent aiming to improve its bearing capacity. 

The monitoring of neighbouring properties for noise and vibration was essential for the protection of both people and properties. 

The vibration levels recorded were found to be within safe limits for nearby properties.
