Utility Pole Foundation Base With Anchor Piles Around Obstacles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for replacing utility poles with small cell poles often require costly and disruptive removal or re-routing of existing utility foundations and obstacles, lacking flexibility in installation.
Innovation Solution
A foundation system comprising a base member with preformed holes, anchor piles, and wedge connectors that allow secure attachment to the ground without drilling, enabling flexible placement around obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing utility foundations and obstacles are removed or re-routed to install new utility poles, then the new poles can be securely installed, but the installation becomes costly and disruptive
Solution Approach 1:
The foundation system is divided into separate components: a base member with preformed holes and anchor adapters that attach to existing obstacles. This segmentation allows the new pole foundation to be installed independently without removing existing utilities, reducing disruption and cost while maintaining secure installation.
Solution Approach 2:
Anchor adapters serve as intermediary components that connect the new base member to existing obstacles such as old concrete foundations or utility structures. These adapters enable attachment to existing obstacles without removal, bridging between new and old infrastructure.
2Reliability
If drilling is required to attach the foundation base member to the ground, then secure attachment is achieved, but installation complexity and cost increase
Solution Approach 1:
The base member is manufactured with preformed holes before installation. These holes are precisely positioned to align with existing obstacles, eliminating the need for on-site drilling operations. The alignment features and preformed holes ensure proper positioning without complex drilling procedures.
3Adaptability or versatility
If the foundation system is designed to accommodate existing obstacles, then installation flexibility is improved, but the structural design becomes more complex
Solution Approach 1:
The anchor adapter is designed as a universal component that can attach to multiple types of existing obstacles including concrete foundations, metal structures, and wooden poles. The adapter's universal design accommodates various obstacle types without requiring custom-designed solutions for each scenario.
Solution Approach 2:
The foundation system separates the base member (with preformed holes) from the anchor adapters (that attach to obstacles). This segmentation allows the base member to maintain a simple, standardized design while the adapters provide the adaptability needed to connect to diverse existing obstacles.
