Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foundation engineering methods for producing columnar structures in the ground, such as high-pressure injection bodies, face challenges in achieving precise dimensions due to varying ground conditions, leading to increased time and costs, especially when multiple bodies are required to provide sealing or stability, and current monitoring techniques are either cumbersome or require significant effort for data evaluation.
Innovation Solution
A method and apparatus that record the rotating and feeding motions of a foundation engineering tool in real-time, combined with additional processing parameters, to generate a three-dimensional model of the structure being produced, allowing for immediate display and identification of defects, enabling prompt corrections and reducing the need for overlap between adjacent structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HPI-bodies are produced with larger overlap to ensure sealing, then sealing reliability is improved, but the number of HPI-bodies increases leading to greater time and cost
Solution Approach 1:
The patent replaces mechanical measurement methods (geophones driven into the ground) with a sensor system integrated into the drill rod that uses electromagnetic or acoustic fields to detect the boundary of the injection body. This substitution enables continuous real-time measurement without additional mechanical intervention, allowing precise determination of HPI-body dimensions and optimization of overlap requirements.
Solution Approach 2:
The patent implements continuous feedback by recording the boundary of the injection body during the injection process itself. The sensor system provides real-time data on the radial extension of the HPI-body, enabling immediate adjustment of injection parameters or positioning of subsequent HPI-bodies to minimize overlap while ensuring sealing integrity.
2Measurement precision
If measuring means is fixed on the drill rod for continuous monitoring, then measurement precision is improved, but the complexity of the construction apparatus increases
Solution Approach 1:
The patent merges the measurement function with the existing drill rod structure by integrating sensors directly onto the drill rod. This combination eliminates the need for separate measuring apparatus and reduces overall system complexity while maintaining continuous measurement capability. The sensor system becomes an inherent part of the injection apparatus rather than an add-on component.
Solution Approach 2:
The drill rod serves multiple functions: it acts as both the injection medium delivery system and the measurement platform. By making the drill rod universal, the patent avoids adding dedicated measuring equipment, thereby reducing apparatus complexity while achieving precise continuous monitoring of HPI-body formation.
3Difficulty of detecting and measuring
If geophones are driven into the ground for monitoring, then measurement capability is improved, but additional workload and human resources are required
Solution Approach 1:
The drill rod with integrated sensors performs measurement automatically during the injection process without requiring separate measurement operations. The system is self-sufficient, using its own structure as the measurement platform, thereby eliminating the need for additional human intervention or separate measurement teams.
Solution Approach 2:
The measurement capability is built into the drill rod before the injection process begins. By preliminarily integrating the sensor system onto the drill rod, the patent eliminates the need for post-injection or separate pre-injection measurement operations, simplifying the overall workflow and reducing operational complexity.
