Deep Cement Stabilisation (DCS) Method

Improvement Principle Solid
Relative mixing caused by the reverse rotation of outer & inner blade to mix the curing agent the slurry & the ground uniformly so as to create a uniformly improved substance. It is able to form max 2.5m diameter improved substance to reduce construction period & construction cost .
 DCS-flow
Advantages Able to reduce the work duration & construction cost by large diameter.
Able to produce uniform improved substance through composite relative mixing.
Able to apply to hard ground because of its heavy duty mixing equipment.
Disadvantages Construction cost is high as compared to compaction method.
Unable to perform installation work close to structures due to mechanical stirrer.
Need to dispose the upheaval soil as construction work in progress.
Applicable Ground Mostly all types of soil such as sandy soil, cohesive soil, and organic soil etc.
Objectives Structural Foundation, Prevent Slip Circle, Prevent Settlement, Prevent Liquefaction
Improvement Effectiveness Cohesive Soil Increase Strength
Reduce Settlement
Suppress Shear Deformation
Sandy Soil Reduce Settlement
Prevent Liquefaction
