Modular Panel Basement Shoring with Self-Drilling Augers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for basement excavation, such as piling and shotcreting, require staged excavation and extensive labor, making them inefficient and costly, and lack the capability for continuous excavation to total depth.
Innovation Solution
A modular panel system with self-drilling panels that can be drilled into the ground, allowing for continuous excavation by using augers or cutting heads depending on ground conditions, and connecting to drill rods to form a shoring wall, which can then be filled with grout or concrete and supported by hydraulic jacks and ground beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If standard piling and shotcreting systems are used, then structural support is provided, but staged excavation is required and labor costs increase
Solution Approach 1:
The shoring system is divided into modular panels that can be independently manufactured and assembled. Each panel contains integrated drill rods and augers, allowing the system to be constructed in discrete units that simplify installation while enabling continuous excavation operations without the complexity of traditional staged piling and shotcreting processes.
Solution Approach 2:
The patent combines multiple functions into a single integrated panel structure: the panel body, drill rods, augers, and support elements are merged into one modular unit. This integration eliminates the need for separate piling and shotcreting operations, allowing continuous excavation while reducing overall system complexity and labor requirements.
2Productivity
If modular panels with integrated augers are used, then continuous excavation is enabled, but panel construction complexity increases
Solution Approach 1:
The drill rods and augers are pre-assembled and integrated into the panel structure during manufacturing, rather than being installed separately in the field. This preliminary integration simplifies panel manufacturing by using standardized components that can be permanently fixed into the panel body, while enabling rapid deployment and continuous excavation operations.
3Length of stationary object
If vertically adjacent panels connect to drill rods, then continuous drilling to total depth is achieved, but connection complexity increases
Solution Approach 1:
The drill rods of vertically adjacent panels are connected to form continuous drill strings that extend from the top panel through multiple intermediate panels to the bottom panel. This continuous connection allows uninterrupted drilling to total basement depth, eliminating the need to stop and restart drilling operations at each panel level, while the modular connection system maintains simplicity through standardized interfaces.

Function Achieved in This Case
This system enables continuous excavation to total basement depth, reducing labor costs and eliminating the need for staged excavation and steel fixing, thus providing a more cost-effective and efficient construction method compared to standard piling and shotcreting systems.
Implementation Method 1
Lowermost panels comprise augers for self-drilling
Implementation Method 2
The drill rods may be stressed by a hydraulic stressing jack

AI summary
Basement shoring apparatus has a modular panel having a panel body having a plurality of parallel drill rod shafts therethrough. Each drill rod shaft has a respective drill rod rotatably engaged therein. Each drill rod extends from a lower edge of the panel body and has a respective auger or cutting head attached at a distal end thereof. Each drill rod is connectable via an upper edge of the panel body for turning. Adjacent drill rods extend to different extent such that blades of respective augers overlap adjacently. As such, modular panel can be drilled into the ground to form shoring wall.
