Abstract
An apparatus for use in compacting or densifying soils includes a tubular casing having a vertical longitudinal axis and an inside surface; a hollow tubular drive shaft aligned with the vertical longitudinal axis of the tubular casing and mounted for rotation therein; a drive motor for rotating the drive shaft; a carrier attached to the drive shaft for rotation therewith; and a cylindrical roller weight in rolling contact with the inside surface of the tubular casing. The carrier engages the roller weight for rotation about the vertical longitudinal axis of the tubular casing. The centrifugal force resulting from rotation of the roller weight is resisted by the tubular casing thereby causing vibration thereof.
Claims20
A centrifugal force vibration apparatus for use in compacting or densifying soils, said apparatus comprising:
- tubular casing means having a vertical longitudinal axis and an inside surface;
- a drive shaft aligned with the vertical longitudinal axis of said tubular casing means and mounted for rotation therein;
- a drive motor for rotating said drive shaft;
- means attached to said drive shaft for rotation therewith;
- and
- roller means in rolling contact with the inside surface of said tubular casing means, said means attached to said drive shaft engaging said roller means for rotation about the vertical longitudinal axis of said tubular casing means, whereby centrifugal force resulting from rotation of said roller means is resisted by said tubular casing means thereby causing vibration thereof.
A centrifugal force vibration system for use in compacting or densifying soils, said system comprising:
- a tubular casing having a vertical longitudinal axis, an inside surface and an upper end;
- means for supporting the upper end of said tubular casing;
- a drive shaft aligned with the vertical longitudinal axis of said tubular casing and mounted for rotation therein;
- a drive motor for rotating said drive shaft;
- means attached to said drive shaft for rotation therewith;
- and
- roller means in rolling contact with the inside surface of said tubular casing, said means attached to said drive shaft engaging said roller means for rotation about the vertical longitudinal axis of said tubular casing, whereby centrifugal force resulting from rotation of said roller means is resisted by said tubular casing thereby causing vibration thereof.
A centrifugal force vibration system for use in compacting or densifying soils and installing vertical structural columns therein, said system comprising:
- a tubular casing having a vertical longitudinal axis, an inside surface, an upper end and a lower end;
- means for at least supporting the upper end of said tubular casing;
- end cap means attached to the lower end of said tubular casing;
- a hollow tubular drive shaft aligned with the vertical longitudinal axis of said tubular casing and mounted for rotation therein, said hollow tubular drive shaft having an outside surface;
- a drive motor between the inside surface of said tubular casing and the outside surface of said hollow tubular drive shaft for rotating said hollow tubular drive shaft;
- means attached to the outside surface of said hollow tubular drive shaft for rotation therewith;
- and
- roller means in rolling contact with the inside surface of said tubular casing, said means attached to the outside surface of said hollow tubular drive shaft engaging said roller means for rotation about the vertical longitudinal axis of said tubular casing, whereby centrifugal force resulting from rotation of said roller means is resisted by said tubular casing thereby causing vibration thereof.
