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.
Claims19
A method comprising:
- using at least one mechanism to press into a ground surface in a downward direction to create a concavity extending to a penetration depth, wherein the penetration depth is comparatively greater for a weaker ground surface;
- at least partially filling the concavity with chemically stabilized aggregate, chemically stabilized soil, or chemically stabilized sand;
- using the mechanism to press the aggregate within the concavity;
- and,
- wherein using the at least one of mechanism to press into different portions of the ground surface comprises using a plurality of spaced-apart mandrels to press into the different portions of the ground surface.
2 more elements
A system comprising:
- at least one mechanism configured to press into a ground surface in a downward direction to create a concavity extending to a penetration depth, wherein the penetration depth is comparatively greater for a weaker ground surface;
- a support configured to carry the at least one mechanism;
- a plurality of spaced apart mandrels;
- and,
- chemically stabilized aggregate, chemically stabilized soil, or chemically stabilized sand for at least partially filling the concavity,
- wherein the at least one mechanism is configured to apply a controlled downward displacement to each of the spaced apart mandrels for creating a plurality of cavities in a ground surface.
