Equipment Pad Erosion Control Barrier Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Erosion of soil beneath equipment pads, such as those supporting air conditioning units and transformers, leads to instability and unsightly conditions, with current solutions being either ineffective or requiring costly excavations and foundations.
Innovation Solution
A prefabricated equipment support pad system integrated with an erosion control barrier, utilizing geosynthetic materials or hard-walled components to prevent soil erosion by extending beyond the pad perimeter and redirecting drainage, which can be easily installed above-grade without extensive excavation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If backfilled soil or rocks are used to repair erosion, then the erosion damage is temporarily filled, but the solution is temporary as the backfilled soil soon erodes away again
Solution Approach 1:
The patent employs disposable erosion control blankets and biodegradable matting that are inexpensive and replaceable. These materials are designed to be temporary protective measures that degrade after serving their purpose, allowing for easy replacement rather than requiring permanent, expensive structural solutions like concrete foundations.
Solution Approach 2:
The patent utilizes composite erosion control materials combining natural fibers (such as coconut coir and wood pulp) with synthetic binding agents. This creates a biodegradable yet structurally sound matting that provides immediate erosion protection while gradually decomposing, offering both short-term reliability and long-term soil stabilization.
2Reliability
If excavation and foundation construction are performed to prevent erosion, then erosion prevention is achieved, but the effort and cost are high
Solution Approach 1:
The erosion control blankets and matting are pre-fabricated and pre-assembled before deployment to the erosion site. This preliminary preparation allows for rapid installation without requiring complex on-site construction, excavation, or foundation work, significantly reducing both labor time and installation cost while maintaining effective erosion prevention.
Solution Approach 2:
The patent employs flexible, thin-film erosion control blankets that can be easily draped and secured over eroded areas. These thin, adaptable materials conform to irregular terrain without requiring rigid structural support or extensive excavation, making installation simple and cost-effective while providing reliable erosion protection.
3Strength
If conventional pads are installed on grade, then equipment support is provided, but the soil beneath the pad begins to erode over time
Solution Approach 1:
The patent introduces erosion control matting and protective blankets as intermediary layers between the equipment pad and the underlying soil. These intermediary materials distribute the pad's weight while preventing direct soil erosion, acting as a mediator that maintains equipment support strength while protecting against the harmful erosion effect.
Solution Approach 2:
Flexible erosion control blankets are installed beneath and around the equipment pad, creating a protective film or shell that prevents soil particles from being washed away while still allowing the pad to function as intended. This thin-film approach provides erosion protection without compromising the pad's structural support capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents soil erosion, maintaining the stability and appearance of equipment pads by retaining soil and managing drainage, thus reducing maintenance costs and efforts.
Implementation Method 1
The erosion control barrier is configured to extend beyond a perimeter of the bottom surface prior to installation of the equipment support pad on the ground and to be manipulated into an erosion-resisting configuration after the equipment support pad is placed on ground that is subject to erosion
Data Source
AI summary
An apparatus configured for above-grade installation on ground to support equipment comprises an equipment support pad joined to an erosion control barrier. The equipment support pad comprises a top surface, a bottom surface configured to contact the ground, and side walls disposed between the top and bottom surfaces. The erosion control barrier is configured to extend beyond a perimeter of the bottom surface prior to installation of the support pad on the ground and to be manipulated into an erosion-resisting configuration after the support pad is placed on the ground. The erosion control barrier may be a geosynthetic, flexible or hard-walled, configured to be inserted into the ground to retain soil and/or to overlay the ground to re-direct drainage, and/or bonded to the equipment support pad. The apparatus may be configured to deter drainage from streaming between the erosion control barrier and the equipment support pad.
