The single column mixing method is one of the oldest and simplest soil mixing methods. It can be used to produce soil mix elements for a wide range of different applications. These include, for example: - retaining walls - deep foundations - slope stabilization - cut-off walls / cut-off blocks - treatment of contaminated soils - soil improvement with individual columns or blocks - prevention of soil liquefaction during earthquakes. Depending on the intended application, the SCM columns can be arranged as single, as tangent, or as overlapping columns. Most common mixing diameters are in a range of 0.6 and 3 m. Drill rigs and sheet piling rigs can be used as base carrier mixing depths for SCM are up to 40 m Deep Soil Mixing (DSM) or Soil Mixing (SM) is a very flexible ground improvement technique used for a wide variety of applications that reinforces extremely soft, very high moisture soils by mechanically mixing them together with a specially designed auger completely in-situ with a cement-like binding agent. It is primarily used to increase bearing capacity, reduce settlement, and provide environmental containment or hydraulic cutoff.1. Core Methodologies There are two primary methods of application, chosen based on the moisture content of the soil and the project requirements.Wet Mixing (WMS)In this method, a cementitious slurry is injected into the ground through a hollow drill string as the mixing tool rotates.• Best for: Stiff clays, silts, and sands where the natural water content is relatively low. Advantage: Offers more precise control over the binder-to-soil ratio and generally results in higher strength columns. Dry Mixing (DMS)This method uses compressed air to deliver dry binder (powder) into the soil. The binder reacts with the existing groundwater to form the soil-cement matrix.• Best for: Very soft soils with high water content, such as peat or soft marine clays.• Advantage: Minimal spoil generation (no slurry to manage) and can be more cost-effective in high-moisture environments.2. Equipment and Tooling The effectiveness of DSM depends heavily on the torque of the drilling rig and the design of the mixing tools.• Single vs. Multi-Shaft: While single-auger rigs are common for small-scale projects, large-scale ground improvement often utilizes multi-shaft rigs (two to four shafts) to create overlapping panels or "blocks." • Mixing Tools: These typically consist of a cutting head followed by several mixing blades or paddles. For harder layers, specialized double-cut augers or high-torque heads are used to ensure the soil is sufficiently pulverized before the binder is introduced.• Injection Systems: High-pressure pumps (wet) or specialized silos and compressors (dry) are integrated with the rig to ensure a continuous flow of binder.
