Abstract
PURPOSE: To enable driving of steel sheet-piles while preventing vibrations and reducing noises by softening a wide range of earth by means of expanding drill bits projected from or stored in the outer peripheral portion of an auger screw unit.
CONSTITUTION: A pair of expanding drill bits 25a and 25b are projected from the outer peripheral portion of a screw 21, so that the diameter of the boring is equal to the radius of the screw 21 plus the lengths of the projected drill bits 25a and 25b. The boring diameter is equal to the sectional distance of the steel sheet-piles 19 as indicated by the character X, so that this range of earth is softened sufficiently. Therefore, the driving of the steel sheet-piles 19 can be conducted without vibrations and noises, irrespective of instinctive hardness of the earth.
