Guidetube-Guided Tunnel Sheet Insertion for Path Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tunnel construction methods are inefficient and costly, and metal sheets often diverge from the intended path during tunnel formation, leading to high costs and time consumption.
Innovation Solution
The method involves inserting guidetubes into the ground and connecting sheets to their ends, then hammering the sheets through the ground to guide the guidetubes in the same direction, using beveled edges to direct the sheets towards the guidetubes, and employing computer systems and programs to control the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If metal sheets are hammered into the ground to form tunnel walls, then tunnel construction can be initiated, but the sheets often diverge greatly from the intended path
Solution Approach 1:
Guidetubes are inserted into the ground before hammering the metal sheets. These guidetubes serve as pre-established guides that define the exact intended path, preventing the sheets from diverging during the hammering process. The guidetubes are pushed through the ground in advance to establish the accurate trajectory before the actual tunnel formation begins.
Solution Approach 2:
The guidetubes act as intermediary elements between the hammering process and the final tunnel path. They mediate the relationship between the metal sheets and the ground, ensuring that the sheets follow the correct path by being physically constrained within the guidetubes during hammering. This intermediary component transfers the intended path from the design to the actual construction.
2Productivity
If traditional tunnel construction methods are used, then construction can proceed, but the process is massively expensive and time-consuming
Solution Approach 1:
The guidetubes are inserted and positioned before the metal sheets are hammered. This preliminary action establishes the exact path and structural framework in advance, allowing the subsequent hammering process to proceed much faster without repeated adjustments or corrections. The pre-established guidetubes eliminate the need for time-consuming trial-and-error positioning during the actual tunnel formation.
Solution Approach 2:
The traditional mechanical process of repeatedly hammering metal sheets into position is replaced by a more efficient system where guidetubes are first inserted to define the path, then metal sheets are hammered along these pre-established guides. This substitution of the sequential hammering process with a guided insertion approach significantly reduces construction time while maintaining structural integrity.
3Measurement precision
If metal sheets are hammered through the ground, then tunnel walls can be formed, but the process lacks precision and control
Solution Approach 1:
The tunnel construction system is segmented into distinct functional components: guidetubes for path definition, metal sheets for wall formation, and connecting elements for structural integrity. This segmentation allows each component to perform its specific function with high precision - the guidetubes handle positioning accuracy while the metal sheets handle structural formation, reducing the overall complexity of achieving both goals simultaneously.
Solution Approach 2:
The guidetubes serve as intermediary elements that provide precise positioning control during the hammering process. They mediate between the hammering action and the final position, ensuring accuracy by physically constraining the metal sheets within the guidetubes. This intermediary component enables precise measurement and positioning without requiring complex measurement systems during the hammering operation.

Implementation Method 1
hammering a sheet into the ground with a beveled front edge of the sheet directed toward the two guidetubes, where the beveled front edge directs the sheet toward the two guidetubes
Implementation Method 2
hammering the sheet through the ground from the ends of the sheet that are opposite of the two guidetubes, thus pushing the two guidetubes through the ground in the same direction as the sheet
