Porous Concrete Clinker Suspension Device for Accurate Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing concrete objects with porous concrete clinkers for water infiltration face challenges such as the need for geotextiles to prevent soil subsidence, difficulties in placing porous clinkers accurately in formwork, and ensuring water permeability without being covered by non-porous concrete.
Innovation Solution
A suspension device comprising hooks, a support structure, and connecting elements allows for easy placement and positioning of porous concrete clinkers in a mould by suspending them from reinforcement, ensuring accurate spacing and preventing corrosion, while being made of corrosion-resistant metal wire for stability and eco-friendliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If porous concrete clinkers are used for water infiltration, then water permeability is improved, but placement accuracy and positioning difficulty increase
Solution Approach 1:
The patent introduces a suspension device as an intermediary tool between the worker and the porous concrete clinker. This device includes hooks that attach to reinforcement bars and a support structure that holds the clinker, enabling precise positioning without direct handling. The intermediary device solves the placement accuracy problem while maintaining the water permeability benefit of porous clinkers.
Solution Approach 2:
The suspension device is prepared in advance with hooks attached to reinforcement bars before the clinker is placed. The support structure is readied to receive the clinker, allowing for systematic and accurate placement. This preliminary preparation eliminates the need for complex positioning operations during the actual placement process.
2Reliability
If geotextiles are used to prevent sand infiltration, then soil stability is improved, but cost and installation complexity increase
Solution Approach 1:
The patent extracts and eliminates the geotextile component from the system by using porous concrete clinkers with appropriate aperture sizes that naturally filter sand particles. The porous structure itself serves the function previously requiring an additional geotextile layer, simplifying the overall system to a single material solution.
3Quantity of substance
If porous concrete clinkers are placed close to reinforcement, then material usage is optimized, but corrosion risk increases
Solution Approach 1:
The suspension device acts as an intermediary that maintains the required spacing between porous clinkers and reinforcement bars. The support structure and connecting elements provide this protective distance without requiring additional non-porous concrete layers, thus maintaining material efficiency while preventing corrosion.
4Productivity
If traditional placement methods are used, then equipment simplicity is maintained, but placement efficiency and accuracy decrease
Solution Approach 1:
The suspension device merges multiple functions into a single tool: the hooks attach to reinforcement for positioning, the support structure holds the clinker, and the connecting elements provide both support and spacing. This integrated design improves placement efficiency without requiring multiple separate tools or complex equipment.
