FALLING BEAM SOILSAW (TRADEMARK), AN ADVANCED PROCESS FOR FORMING UNDERGROUND CUTOFF WALLS

Barriers for the reduction of the subsurface movement of liquids have always been difficult to construct and varify. An economical barrier installation procedure that will satisfy both strength and permeability properties and could be verified would greatly enhance the available technology. The objective of this project was to fully develop and commercialize SoilSaw (Trademark[TM]) Barrier System (BS) technology for use in levee reinforcement, earth dam reinforcement, slope stabilization, and as a method of containment at hazardous waste and manufacturing sites. The product is an advanced technology to install an underground seepage barrier using a machine, the SoilSaw (TM), that should be capable of mixing soil and slurry to form the barrier to depths exceeding 100 ft.(30.48m). Installation of four walls at demonstration sites has demonstrated that the SoilSaw (TM) technology is a feasible option for rapidly installing slurry walls. The installation of a 45 ft. (13.72m) deep wall at the Savannah River Nuclear Plant project confirmed strength and permeability specifications for this particular phase of the research [a minimum 30 ft. (9.14m) depth and 10 to the 6th power -cm/sec permeability]. Quality assurance testing for strength and permeability on the limited number of samples that could be attained from the demonstration walls appears to verify project specifications, but there are not enough data to accurately predict full construction productivity.
