Vibratory systems

|
Pile driving with vibratorA main application for RTG rigs is pile driving with hight frequency vibrators. For construction retaining walls, sheet piles or steel beams are driven (and extracted in case of temporary works). |

|
Displacement pilingA casing is vibrated into the ground and backfilled with gravel or concrete. When extracting the casing, the vibrating energy is compacting the gravel column. Vibropiles are used as load bearing elements or as a ground improvement system. |

VIB-wall systemVIB-walls are used as cut-off walls. A heavy steel beam (IBP 1000 typical) is driven to a predefined depth by a hydraulic vibrator. The slim gap which is created by the beam is filled with slurry when extracting the beam. A continuous wall is formed by an overlapping construction of elements. |

|
Deep vibratorsA hydraulically driven vibrator cell with rotating eccentric weights is mounted at the bottom of the deep vibrator TR, producing vibrations in horizontal direction. It is a typical process for soil improvement by compacted columns. Depending on the soil conditions sand (vibro-compaction), gravel (vibro- replacement) or concrete is added during the construction process. |
