Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reinforcing strips are limited in their use with insitu soils outside specific grain size curves, requiring additional treatments or layers for friction, filtration, and drainage, and cannot effectively manage interstitial pressures and fluid dissipation in confined environments.
Innovation Solution
A composite reinforcing strip with permeable channels and surface openings allows fluid communication, enabling fluid absorption, drainage, and filtration while maintaining structural reinforcement, suitable for use in cohesive and clayey soils without additional layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reinforcing strips are used with insitu soils outside specific grain size curves, then the applicability of reinforcing strips is improved, but additional treatments or layers are required which increases device complexity
Solution Approach 1:
The reinforcing strip is designed to perform multiple functions simultaneously: reinforcement through high-tenacity fibres, filtration through porous structure, and drainage through longitudinal channels. This multi-functional design allows the strip to be used with various insitu soils without requiring additional specialized layers, making it universally applicable across different soil conditions.
Solution Approach 2:
The invention combines previously separate components (reinforcing fibres, filtration layer, drainage system) into a single integrated composite strip structure. The covering capsule encapsulates both reinforcing fibres and longitudinal drainage channels, creating a unified element that eliminates the need for separate installation of multiple layers.
2Strength
If strips are totally encapsulated with reinforcing channels, then structural strength is improved, but ability to dissipate interstitial pressures and filter fluids is reduced
Solution Approach 1:
The covering capsule is designed with a porous structure that allows fluid passage while maintaining structural integrity. The porous material enables interstitial pressure dissipation and fluid filtration without compromising the reinforcing capability, resolving the contradiction between strength and fluid management.
Solution Approach 2:
The strip structure is segmented into distinct functional zones: reinforcing fibres for strength, longitudinal channels for drainage, and porous covering for filtration. This segmentation allows each component to optimize its specific function while working together as an integrated system.
3Reliability
If additional separator filter and frictional granular layer are added to manage fluids, then fluid management capability is improved, but device complexity and installation time increase
Solution Approach 1:
The separator filter and drainage functions are merged into the single composite strip structure through the porous covering and longitudinal channels. This integration eliminates the need to install separate granular layers and filter materials, significantly reducing installation time while maintaining fluid management capability.
Solution Approach 2:
The reinforcing strip is designed as a universal solution that simultaneously provides reinforcement, filtration, and drainage functions in one element. This multi-functionality eliminates the need for multiple additional layers and materials, streamlining the installation process.
4Adaptability or versatility
If strips are used in confined environments with cohesive soils, then applicability is improved, but risk of damage from interstitial pressures increases
Solution Approach 1:
The longitudinal drainage channels are pre-formed within the strip structure during manufacturing, creating ready-made pathways for fluid escape. This preliminary preparation allows interstitial pressures to be dissipated efficiently when the strip is installed in confined cohesive soils, preventing damage before it occurs.
Solution Approach 2:
The porous covering capsule acts as an intermediary between the reinforcing fibres and the surrounding soil, allowing fluid passage while maintaining structural support. This intermediary structure enables the strip to function effectively in confined environments by mediating between reinforcement needs and fluid dissipation requirements.
