Drilling Apparatus for Voids-Free Soil Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil stabilization and anchoring techniques often result in voids within and between the solidifying material and the soil, leading to reduced stabilization and resistance to displacement, as they typically involve injecting material after drilling or withdrawing the drilling apparatus.
Innovation Solution
A system that combines a solidifying material swivel, a drive connector, and a drilling apparatus, allowing for the injection of solidifying material under pressure during the drilling process, ensuring voidless placement and increased stabilization by either leaving the apparatus in place or withdrawing it with continuous material injection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solidifying material is injected after drilling or the drilling apparatus is withdrawn, then the drilling operation can be completed, but voids are created within and between the solidifying material and soil, reducing stabilization effectiveness
Solution Approach 1:
The drilling apparatus is designed with internal channels and cavities that are prepared in advance to receive and contain the solidifying material during injection. The apparatus maintains its position in the ground while the material is injected through predetermined pathways, ensuring complete filling without voids and eliminating the need for post-drilling operations.
2Reliability
If the drilling apparatus is removed after drilling, then the hole can be filled with solidifying material, but the drilling apparatus cannot provide continuous support during material injection
Solution Approach 1:
The drilling apparatus serves multiple functions simultaneously: it acts as both the drilling tool and the injection conduit for the solidifying material. The apparatus remains in the ground to provide structural support and anchorage while material is injected through its internal channels, eliminating the need for separate operations and equipment.
3Manufacturing precision
If solidifying material is injected under pressure during drilling, then voids are prevented and stabilization is enhanced, but the drilling apparatus must maintain position and contain material flow
Solution Approach 1:
The drilling apparatus is divided into functional segments including the drilling bit, internal channels, cavities, and outlet openings. These segmented components work together to control the flow and distribution of solidifying material under pressure, ensuring uniform placement while maintaining the structural integrity needed for drilling operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method achieves enhanced soil stabilization and resistance to displacement by preventing voids, allowing for adaptable, rapid, and uniform construction of anchors or piles across various terrains and soils, using interchangeable drilling machines.
Implementation Method 1
a solidifying material to be pumped under pressure during the drilling process, thereby preventing voids both within the solidifying material and between the solidifying material and soil

AI summary
This invention relates to a system and method for use in stabilizing different types of soils and/or creating anchorage and more particularly, to a system and method for injecting various types of solidifying material into a subsurface through a drilling apparatus during the drilling operation. The drilling apparatus may be removable and reusable used to create a micro or mini pile for soil stabilization, or alternatively it can be left in place to be used in conjunction with grout and similar materials for forming an anchor or load carry pier. A solidifying material swivel, a drive connector and a drilling apparatus, in combination are attached to a power drive unit. In one preferred embodiment, the drilling apparatus remains within the soil subsurface, encased in solidifying material. In another preferred embodiment, the drilling apparatus is removed leaving a homogenous pile of solidifying material behind.
