Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional foundations for power transmission towers in remote and rugged locations are challenging to install and maintain due to environmental and logistical issues, requiring innovative solutions for structural integrity and ease of installation.
Innovation Solution
A piling foundation assembly comprising a base structure with upper and lower plates connected by webs, secured to piles driven into the ground, allowing for prefabricated and easily installable foundations that support operating equipment like power transmission towers, with features such as plate apertures and equipment apertures for securing fasteners and reducing environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional concrete foundations are used for power transmission towers in remote locations, then structural stability is achieved, but installation difficulty and environmental disruption increase significantly
Solution Approach 1:
The foundation is divided into multiple independent steel piles instead of a single monolithic concrete structure. Each pile can be independently driven into the ground using portable equipment, and they work together to provide collective structural stability. This segmentation allows installation in remote locations without requiring large concrete pouring operations.
Solution Approach 2:
The patent replaces the traditional concrete mechanical system with a steel pile system. Instead of pouring and curing concrete (a complex mechanical process requiring formwork, reinforcement, and curing time), steel piles are directly driven into the ground using impact or vibration methods, significantly simplifying the installation process while maintaining structural integrity.
2Strength
If traditional concrete foundations are used, then load-bearing capacity is sufficient, but environmental disruption and invasive equipment requirements increase
Solution Approach 1:
By using multiple smaller steel piles instead of one large concrete foundation, the environmental impact is distributed and minimized. Each pile requires a small access point, and the spaces between piles allow natural ground features to remain intact, reducing overall disruption to the remote terrain.
Solution Approach 2:
The foundation uses steel material instead of concrete, creating a composite structure when combined with the natural ground. Steel piles can be driven through various soil types and rock layers, adapting to the existing ground conditions without requiring extensive excavation or removal of natural features, thus reducing environmental harm.
3Productivity
If prefabricated base structures are used with multiple piles, then installation efficiency improves, but structural complexity increases
Solution Approach 1:
The base structure merges multiple steel piles into a single unified platform through a steel grating system. This consolidation allows the entire foundation assembly to be installed as one unit, improving productivity while the modular nature of the grating system keeps the structural complexity manageable through standardized components.
Solution Approach 2:
The steel grating base structure serves multiple functions simultaneously: it distributes loads across all piles, provides a stable mounting surface for equipment, allows pedestrian access, and facilitates drainage. This multi-functionality reduces the need for additional structural elements, maintaining simplicity despite the multi-pile configuration.

AI summary
A base structure for a piling foundation is provided. The base structure includes an upper plate and a lower plate. The lower plate is spaced a distance below the upper plate and is oriented substantially parallel to the upper plate. Both the upper plate and the lower plate include a number of plate apertures therethrough. The upper plate and the lower plate are connected to each other by webs configured to provide structural integrity to the base structure. Further, a piling foundation assembly for supporting operating equipment and a method for installing a piling foundation assembly are provided.
