Tilt Tower Pipe Auger Anchor Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tilt tower systems face challenges in securely anchoring to the ground, particularly due to harmonic vibrations caused by wind or other forces, which can lead to destructive failures at non-reinforced coax ports.
Innovation Solution
A tilt tower and pipe auger anchor assembly that includes a mast with a flange plate and a pipe auger anchor with reinforced coax ports, where the pipe auger anchor features a helical auger for penetration and reinforced steel members to stabilize the coax ports, and a mating flange plate with anchor bolts for secure attachment to the mast, ensuring perpendicular alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional precast concrete foundation is used to anchor the tilt tower, then the installation process requires extensive excavation and concrete pouring, but the anchoring strength and stability are insufficient to withstand harmonic vibrations from wind forces
Solution Approach 1:
The anchor system is divided into separate modular components: a pipe auger portion for ground penetration, a flange plate for mast attachment, and a coax port assembly. This segmentation allows each component to be optimized independently and simplifies installation by eliminating the need for extensive concrete pouring and excavation.
Solution Approach 2:
The traditional mechanical anchoring system using concrete foundations and embedded bolts is replaced with a screw-threaded auger mechanism that penetrates the ground and secures the mast through threaded engagement. This substitution provides superior vibration resistance while reducing installation complexity.
2Ease of operation
If coax ports are provided in the anchor assembly for cable access, then cable installation is simplified, but the ports become weak points susceptible to destructive failure from harmonic vibrations
Solution Approach 1:
The coax ports are locally reinforced with steel members that extend into the pipe auger body, providing targeted strengthening at the specific locations where cables need to pass through. This local reinforcement maintains cable installation ease while preventing vibration-induced failure at the port locations.
Solution Approach 2:
The anchor assembly combines different materials with complementary properties: the pipe auger body provides structural integrity and vibration resistance, while steel reinforcement members strengthen the coax port areas. This composite construction maintains both ease of cable installation and reliability under vibrational loads.
3Ease of manufacture
If the mast flange plate is directly bolted to a concrete foundation, then installation is straightforward, but the connection lacks the stability to prevent destructive failures under wind-induced vibrations
Solution Approach 1:
The simple bolt-to-concrete connection is replaced with a threaded auger mechanism that screws into the ground, providing mechanical interlocking and vibration resistance. The flange plate remains bolted to the auger body, maintaining assembly ease while the auger-ground connection provides superior stability under vibrational loads.
