Connecting Ring Anchoring Multilayer Soil Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multilayer ground anchoring devices face challenges in precise positioning of the casing tube due to ground irregularities, leading to potential leaks of sealing material between the upper and lower layers.
Innovation Solution
Incorporation of a connecting ring that provides a leak-tight connection between the hollow rod and the casing tube, extending to the interface between the upper and lower layers, ensuring correct positioning and sealing, regardless of ground irregularities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the casing tube is positioned based on depth measurements alone, then the positioning process is simple, but the casing tube cannot be accurately positioned at the interface between upper and lower layers due to ground irregularities
Solution Approach 1:
The connecting ring acts as an intermediary element between the hollow rod and the casing tube. It provides a reference surface that allows the casing tube to be positioned accurately at the interface between upper and lower layers, compensating for ground irregularities while maintaining a simple positioning process.
2Device complexity
If the casing tube is positioned without a connecting ring, then the device structure is simpler, but sealing material leaks into the upper layer through gaps between the casing tube and the interface
Solution Approach 1:
The connecting ring serves as a mediator that ensures reliable sealing by providing a stable reference surface for the casing tube at the layer interface. This prevents leakage of sealing material into the upper layer while adding minimal structural complexity to the device.
3Manufacturing precision
If the connecting ring is added to ensure accurate positioning and sealing, then positioning accuracy and sealing effectiveness improve, but the device complexity increases
Solution Approach 1:
The connecting ring is designed as a separate, modular component that can be independently manufactured and assembled. This segmentation allows for precise manufacturing of the ring itself while keeping the overall device structure manageable and not excessively complex.
4Ease of operation
If sealing material is injected without a connecting ring, then the injection process is simpler, but the sealing material leaks into the upper layer causing material loss
Solution Approach 1:
The connecting ring acts as a barrier and reference structure that prevents sealing material from leaking into the upper layer during injection. This maintains the simplicity of the injection process while eliminating material loss through proper sealing at the layer interface.
