Technique
Raito offers soil stabilization techniques for diverse project needs. Its specialized equipment can treat a wide range of soil conditions to great depths.
Multi-Auger Soil Mixing
DSM is an in-situ soil mixing technology that mixes existing soil with cementitious materials using mixing shafts consisting of auger cutting heads, discontinuous auger flights, and mixing paddles. The mixing equipment varies from single to eight-shaft configurations depending on the purpose of the deep mixing. The soil-cement produced generally has higher strength, less compressibility, and lower permeability than the native soils.
Soil Mixing Wall
The RSW method mixes in-situ soils with cement grout or other reagent slurries using a multiple-shaft auger to produce continuous subsurface soil-cement walls for excavation support, groundwater or underground pollutants control, or ground reinforcement. The soil cement is usually reinforced with steel H-piles for excavation support and groundwater control.
Single Large Diameter
RAS Column is an advanced deep soil mixing method based on mechanical soil mixing technology to produce a soil-cement column of 1.4m to 2.5m diameter. The mixing head is equipped with a counter-rotation mechanism. This unique mechanism efficiently breaks and mixes in-situ soil with cement-based reagents, producing more homogenous and higher-quality soil-cement columns.
Shallow Soil Mixing
SCM (Surface Compact Mixing) is a method for mechanically mixing in-situ soil with cement powder or slurry. SCM provides two types of equipment, Rotary Blender and Bucket Mixing, which can be selected depending on improvement objectives and depth. The unique mixing mechanism offers efficient, cost-effective, and quality improvement. A larger plant is not necessary. The mixing device can be attached to a local 0.8-1.9m3 excavator.
