The Vibrolance® is a cylindrical hydraulic vibratory system, composed of a vibrator, an isolator and various extension tubes. The vibrator contains an eccentric that continuously oscilates, generating radial vibrations. These vibrations are used to penetrate the ground and then to treat the soil, according to the chosen ground improvement technique (vibro compaction or stone columns). 5 meter extension tubes allow the Vibrolance® to adjust to almost any treatment depth. Vibrolances can be equipped with a Bottom Feed System (BFS), for stone column applications. In this case, a stone tube and a stone tank with a stone gate, will be added to the Vibrolance®.

BOTTOM FEED:

The BFS system controls the length and the diameter of the stone column, better than the Top feed system. In addition, there is no risk of soil collapse while the stone is released, because the Vibrolance is not withdrawn from the ground until the stone column is finished.

Thus, the BFS system allows the contractor to have a continuous production process that results in higher productivity and time savings.
