CaseStudy: Vibro Stone Columns

Vibro stone columns are a ground improvement technique, used to stabilise areas of weak or variable soils or made ground.  During 2021/22 ABI Equipment provided Tritech Ground Engineering with an ABI TM 13 Mobilram for various projects across the UK.  On each occasion the rig was used to install Vibro-Stone Columns. 

Each site was treated to a depth between 4-6m.  This new rig combines excellent operational efficiency with low noise level.  Fuel consumption has proven to be only 120-litres per day.  This compact but powerful rig utilises a 209kW low emission/compliant diesel engine combined with ABI’s Efficiency Drive System and MRZV12VV variable static moment, variable frequency vibrator to achieve these excellent figures.

The TM13 is incredibly compact with a transport width and length of just 2.5m x 9.0m, and weighs only 40-tonnes.
