Slurry Walls

Megan Lithgow, Grad.

Subsurface vertical barriers (slurry walls) are used in a variety of both environmental and structural applications in civil engineering. In environmental remediation projects, barriers can be used to impede the migration of contaminants. When the barrier is in place, contaminated water is diverted from further permeating the soil layers through rock fractures or underneath dams and levees. Barriers also impede clean water from entering any additional remediation systems intended only for the contaminated water, such as a pump and treat system. A new method, Trench Cutting Remixing (TCD) Deep Wall contruction method, is a method pioneered by the Japanese that cuts and mixes existing soil with injected solidifying agents using large, chainsaw-like equipment. This technology can be used to construct both vertical and inclined barrier walls in a variety of applications such as riverbed stabilization, saltwater intrusion, and environmental remedation projects......Read More
