Top Feed Vibroflotation

In the method of top feed vibroflotation, the OMS vibroflotation probe is positioned where a stone column is required and is vibrated into the ground to the desired depth with the help of water jetting. At this point, a gap has been generated around the vibroflotation probe and is then fed with gravels of a certain size, based on the ground conditions. When the probe is extracted, the gravels in the gap displace the surrounding ground which then creates a stone column and compresses the ground. The compression of the ground is tracked by the monitor on the hydraulic power unit.
