Frozen Soil Barrier Technology. Innovative Technology Summary Report
The technology of using refrigeration to freeze soils has been employed in large-scale engineering projects for a number of years. This technology bonds soils to give load-bearing strength during construction to seal tunnels, mine shafts, and other subsurface structures against flooding from groundwater, and to stabilize soils during excavation. Examples of modern applications include several large subway, highway, and water supply tunnels. Ground freezing to form subsurface frozen soil barriers is an innovative technology designed to contain hazardous and radioactive contaminants in soils and groundwater. Frozen soil barriers that provide complete containment (V configuration) are formed by drilling and installingmore »
