The vibro stone columns installation process is simple and streamlined. First, a vibroflot is driven down into the ground with a device to create a hole. Granular material is then inserted into the device and compacted to create a column in the ground Vibro concrete columns (typically referred to as VCCs) are a very time and cost efficient method of providing solid foundations in softer ground. Vibro Concrete Columns also provide a more sustainable solution as they produce much less spoil than conventional piling system and typically use less concrete. Vibro concrete columns can be installed quickly in suitable ground conditions and offer a. Column length plays an important role in determining the settlement performance of an improved ground. The feasibility of ECM for use with floating columns is shown here. The results of a FEM analysis for floating columns, with 100 kPa of loading and a 40° friction angle, were used to compare the results with ECM. The calculation for ECM was done manually, using Eq. , but written in the form. Rigid Inclusions / Vibro Concrete Columns. The soils on some sites are too soft for ground improvement with vibro stone columns and rammed piers. On these projects, vibro concrete columns (VCCs) may be the most feasible and cost-effective technique to mitigate the soft soils, meet settlement criteria and improve bearing capacity for the structure
Vibro stone and vibro concrete columns are installed on a grid using a vibrating poker, or vibroflot, mounted on a specialist vibropiling rig. This is driven into the ground, with or without air flush, to the desired depth. Stone or concrete is pumped into the hole through the vibroflot, which compacts the material to form a column as it is withdrawn. Together, the grid of columns strengthens. Vibro stone columns or aggregate piers are an array of crushed stone pillars placed with a vibrating tool into the soil below a proposed structure.
