Falling Beam SoilSaw (Trademark), An Advanced Process for Forming UndergroundCutoff Walls

摘要

The Falling Beam SoilSaw is a method for forming a continuous barrier wall atdepths between 30 and 120 ft deep. The objective of this project was to fully develop and commercialize SoilSaw technology for use in underseepage control (pre- and postconstruction), slope stabilization, and as a method of containing contaminants at hazardous waste sites. Specifically, the objectives were to install a demonstration wall using the SoilSaw technology, determine the physical dimensions (width and depth) of the wall, and determine the in-place properties (permeability and strength). During the time frame of the CPAR study, several walls were constructed by Halliburton NUS for which USACE visually monitored but not strength or permeability data were supplied. Therefore, the results of the objectives will be based on the CPAR data presented in this report. (MM).
