DIGGING FROZEN GROUND
The following methods of trench construction in frozen ground were investigated: (1) utilization of a disk saw in both vertical and horizontal positions; (2) utilization of drop hammers as pressure cutters and of wedges to dispose of the blocks produced; (3) cutting narrow channels in the frozen gro...
