Abstract
Systems and methods to provide pressed aggregate-filled cavities for improving ground stiffness and uniformity are disclosed. According to an aspect, a method includes using a mechanism to press into a ground surface in a substantially downward direction to create a concavity. The method also includes substantially or completely filling the concavity with unstabilized or chemically stabilized aggregate, soil, or sand. Further, the method includes using the mechanism to press the aggregate within the concavity to achieve a desired ground stiffness.
Claims32
A method comprising:
- independently controlling each mandrel of a plurality of mandrels to press into a ground surface in a downward direction to create concavities;
- providing a support configured to carry the mandrels, wherein the support defines a plurality of openings positioned for allowing the mandrels to pass through respective openings when moved in the downward direction;
- filling the concavities with unstabilized or chemically stabilized aggregate, soil, or sand;
- and
- using the plurality of mandrels to press the aggregate within the concavities.
A method comprising:
- independently controlling each mandrel of a plurality of mandrels to press into different portions of a ground surface in downward directions to create a plurality of cavities;
- providing a support configured to carry the mandrels, wherein the support defines a plurality of openings positioned for allowing the mandrels to pass through respective openings when moved in the downward direction;
- filling the cavities with unstabilized or chemically stabilized aggregate, soil, or sand;
- and
- using the mandrels to press the unstabilized or chemically stabilized aggregate, soil, or sand within the cavities.
A system comprising:
- a plurality of mandrels configured to each be controlled independently of one other to move in a downward direction;
- a support configured to carry the mandrels, wherein the support defines a plurality of openings positioned for allowing the mandrels to pass through respective openings when moved in the downward direction;
- and
- a mechanism attached to the support and mandrels, and configured to independently move each of the mandrels in the downward direction.
A system comprising:
- a plurality of mandrels configured to each be controlled independently of one other to move in a downward direction;
- a support configured to carry the mandrels;
- a mechanism attached to the support and mandrels, and configured to independently move each of the mandrels in the downward direction;
- and
- one or more skids attached to an underside of the support.
