Description: |
MecTool is an integrated system of components, engineered
to provide a variety of in-situ remediation methods for contaminated soils.
It consists of soil boring and mixing tools, a hollow stem Kelly bar with
integral gas or fluid delivery system, very high torque earth drilling
equipment, soil shroud containment and collection system, and a computerized
monitoring system for control and documentation of soil treatments. MecTool
can treat a soil column, up to 14 feet in diameter, to depths exceeding 100
feet. The Kelly bar is supported vertically by a construction crane. The
Kelly bar is rotated by a drilling attachment mounted on the crane. Mounted
on the Kelly bar is a drill with four horizontal blades that have cutting teeth.
Steam and chemical remediation compounds are pumped into the top of the Kelly
bar and injected into the soil through orifices along the trailing edges of
the blades. Fluid components are designed to fit each particular remediation
treatment. Surrounding the Kelly bar is a dome shaped shroud that rests on
the surface of the ground to capture and allow purification of any volatiles
resulting from mixing the soil column. The system was patented in 1992. |
