Abstract:
A lateral compaction auger used in the formation of bore holes adapted to receive cementious material for the formation of piles and comprising:an elongated central shaft presenting a lower end;outwardly extending helical auger flighting supported on said shaft,said shaft and flighting being cooperatively configured for lateral displacement and compaction of soil during rotation of the auger;a plurality of elongated rollers each presenting an outer periphery; andmeans rotatably mounting each of said rollers between respective flight sections of said auger flighting, including an elongated, arcuate in cross-section casing member operatively coupled with said shaft and complemental with a corresponding roller received therein,the clearance between each roller periphery and the adjacent casing being sufficiently small to prevent undue buildup of earth on the roller during use of the auger.
