Cutting Frozen Ground with Disc Saws

Abstract

The largest commercially available disc saws (7 ft diameter) were tested in frozen ground. Cutting performance was reasonably attractive, specific energy consumption was acceptable, but cutter durability in frozen gravel was judged to be totally inadequate. A new cutter system was developed for the saw that provided best general capabilities, and a dramatic improvement in cutter durability was achieved. The modified saw cut slots 3.7 in. wide and 30 to 34 in. deep at rates up to 6.6 ft/min in coarse frozen gravel and up to 16.3 ft/min in frozen silt.
