As a trailblazer in the field of soil mixing, Schnabel highlights that accurate soil mixing is a critical factor in developing robust earth-retention strategies. When carried out accurately, the blending process generates a soilcrete amalgam characterized by enhanced robustness and decreased permeability.
The usage of deep soil mixing equipment significantly aids in constructing earth-retaining configurations where a groundwater cut-off is indispensable. This typically involves Schnabel drilling a set of converging soilcrete columns to form an uninterrupted groundwater cutoff barrier.
While the soilcrete mixture is still damp, steel piles are commonly integrated to boost its strength. This means the treated soil’s enhanced strength can enable it to bridge the gaps between piles. Likewise, lower permeability attributed to a soil mix wall allows for excavation under predominantly dry conditions with minimal impact on the surrounding water table levels.
Beyond creating earth-retaining structures, the use of deep soil mixing equipment can help to form impenetrable barriers beneath the ground level, irrespective of whether excavation takes place. This is particularly beneficial in minimizing dam seepage or containing contaminated groundwater. Moreover, foundation soils can be ameliorated to increase their sturdiness and minimize the potential for liquefaction in seismic events.
