Aggregate Panel System for Corrosion-Resistant Wall Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing base walls in structures such as manholes and vaults often deteriorate and leak, requiring costly repairs or replacements due to lack of effective corrosion protection and structural support.
Innovation Solution
An aggregate panel system comprising a rigid panel with a fluid-impermeable outer layer, attached to a base wall, filled with hardening aggregate material that mechanically bonds to both the panel and the wall, providing structural support and corrosion resistance, with optional panel braces and weldable edges for enhanced rigidity and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If aggregate fill is poured between the panel and base wall to provide structural support, then the base wall gains structural reinforcement, but the installation process becomes more complex and time-consuming
Solution Approach 1:
The panel offsets are pre-attached to the panel before installation, establishing the gap geometry in advance. This preliminary action simplifies the subsequent aggregate pouring process by ensuring proper spacing is already configured, reducing on-site complexity while maintaining structural support benefits
2Manufacturing precision
If panel offsets are used to maintain gap between panel and base wall, then proper spacing is ensured for aggregate fill, but the device complexity and number of components increase
Solution Approach 1:
The panel offsets are merged with the panel as a single integrated component rather than separate parts. This combining approach ensures precise gap spacing is built into the panel itself during manufacturing, eliminating the need for additional adjustable spacing components and simplifying the overall device complexity
3Reliability
If the panel uses a fluid-impermeable outer layer to prevent corrosion, then corrosion protection is improved, but the material cost and manufacturing complexity increase
Solution Approach 1:
The panel employs a composite structure combining a rigid structural layer with a fluid-impermeable outer layer. This composite material approach provides superior corrosion resistance and structural integrity simultaneously, while the layers are integrated during panel manufacturing to avoid excessive complexity
4Strength
If panel braces are added to increase rigidity, then the panel structural performance improves, but the installation time and labor requirements increase
Solution Approach 1:
The panel braces are pre-positioned and attached to the panel before the aggregate fill is poured. This preliminary action ensures proper brace placement and allows the aggregate to flow around them naturally, reducing on-site adjustment time and labor requirements while achieving the desired rigidity enhancement

Function Achieved in This Case
The aggregate panel system offers a quick, inexpensive, and reliable method to reinforce and protect existing base walls from corrosion and leakage, extending their longevity and reducing maintenance costs.
Implementation Method 1
The aggregate fill configured to harden to a solid aggregate fill and thus structurally support both the base wall and the rigid panel. When hardened, the solid aggregate fill is mechanically bonded to the first panel and also mechanically bonded to the first base wall.
Implementation Method 2
the first panel comprises a fluid impermeable, non-porous outer layer... To ensure that the base wall nor the aggregate fill nor the panel are deteriorated by nor permeated by fluids, including corrosive fluids
Implementation Method 3
in one example may be attached the first side of the first panel comprising a weldable perimeter face edge... an overlap panel may be welded or otherwise sealed to the perimeter edge of both the first panel and the second panel

AI summary
An aggregate panel system comprising in one example: a rigid first panel having: a first side comprising a fluid impermeable, non-porous outer layer; a second side facing a first base wall to which the first panel is attached. Also disclosed is at least one optional panel brace fixed to the second side of the first panel and extending toward the base wall, the panel brace configured to increase rigidity of the first panel. An aggregate fill (e.g. concrete) is then poured or otherwise disposed between the first panel and the first base wall to fill the region therebetween. The aggregate fill configured to harden to a solid aggregate fill and thus structurally support both the base wall and the rigid panel.
