Compensation grouting TREVIMIX TURBOJET

ground improvement

With the TREVIMIX-TURBOJET technique one obtains columns of consolidated soil and geometry defined by the tool’s dimensions with in-situ mechanical mixing of the soil with the supply of a water-cement mixture injected at high pressure. Good results with the TURBOJET treatment are strictly dependent on the nature and composition of the soil in which the operation is being carried out. Operating specifications The stabilizing agent is already introduced into the soil while drilling, as a stable water/cement mixture with the possible addition of additives. Separation and mixing of the soil is achieved by the combined action of mechanical tools, aided by a system of high pressure jets which convey the consolidating agent. The jets with their high kinetic energy promote the breakdown of material, optimizing the mixing and increasing the final quality of the soil-binder mixture, especially in terms of the consolidated section’s resistance and homogeneity. Technical data Column diameter: 400 to 1500 mm; greater diameters can be used depending on the presence of particularly favourable soil. Maximum depth of treatment: 25÷30 meters depending on soil diameter and consistency.
