This Jet-gun machine is designed to bring the soil inside a pile in controlled fluidization. A medium such as sand in water has virtually zero resistance in complete state of fluidization. It acts as liquid.
The Jet-gun can be combined with other installation methods, such as vibration pile driving and traditional pile driving methods. It serves to reduce ground resistance on the inside of the pile.
For the influence of the use of the Jet-gun on the bearing capacity of the foundation, it is important that no water flows out through the bottom. The Jet-gun method is only applied after a preliminary study of the soil and application of the Fluidflow prediction model, developed by GBM Works in collaboration with Deltares.
Based on simulations with Fluidflow for your typical conditions, GBM engineers can advice optimal working conditions and machine settings.
