OPTIMIZATION OF SOIL MIXING TECHNOLOGY THROUGH

Enhanced soil mixing is aprocess used to remove volatile organic compounds (VOCS)from soil. In this process, also known as soil mixing with thermally enhanced soil vapor extraction, or SM7TESVE, a soil mixing apparatus breaks up and mixes a column of soil up to 9 m (30 fi) deep; simultaneously, hot air is blown through the soil. The hot air ...

06/12/2014  Optimization could account for savings of about 50% in the cost of soil mixing. The analysis indicates that simulated displacements can be reduced significantly when both the soil-mixing and the umbrella vault techniques are used. Deep soil mixing is more effective and adaptable, whereas the umbrella vault method has to be used jointly with other techniques to stiffen the upper soil layers ...
