Temporary Support Structure for Transmission Tower Tripod Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for repairing or replacing guyed lattice tower tripods in environmentally sensitive areas are costly and disruptive, often requiring complete tower replacement, which is impractical due to environmental concerns and logistical challenges.
Innovation Solution
A temporary support structure that transfers the tower's load from the tripod to existing piles, allowing for the repair or replacement of the tripod, brackets, and adapters without removing the tower from service or installing additional piles, using a bearing platform system, lifting system, and flower pot adapter assembly to bypass the tripod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If complete tower replacement is performed, then the deteriorated tripod and foundation can be fully replaced, but the cost and environmental disruption increase significantly
Solution Approach 1:
The invention divides the tower support system into separable components: the tower structure, the tripod, and the foundation piles. This allows selective replacement of only the deteriorated tripod and brackets while retaining the tower and existing piles, thereby reducing environmental disruption and cost compared to complete replacement.
Solution Approach 2:
The invention introduces temporary support structures as intermediary elements to transfer the tower load away from the deteriorated tripod during replacement. These temporary supports act as mediators that enable safe disconnection and replacement of the tripod without compromising tower stability, allowing repair work to proceed with minimal environmental impact.
2Ease of repair
If complete tower replacement is performed, then all deteriorated components can be replaced, but the cost increases significantly
Solution Approach 1:
The invention segments the tower support system into independently replaceable components. Only the deteriorated tripod and associated brackets are replaced, while the tower structure and foundation piles are retained. This selective replacement approach significantly reduces material costs, labor requirements, and overall project expenditure compared to complete tower replacement.
Solution Approach 2:
The invention enables recovery and reuse of valuable components such as the tower structure and foundation piles. By retaining these elements and only discarding the deteriorated tripod and brackets, the system maximizes resource utilization and minimizes replacement costs, making the repair economically viable.
3Ease of repair
If temporary support structure is installed, then the tower can be supported independent of the tripod, but the device complexity increases
Solution Approach 1:
The temporary support structures serve as intermediary elements that temporarily assume the function of load support during the tripod replacement process. These structures are designed to be relatively simple in configuration, using basic support members and adjustment mechanisms, thereby minimizing the increase in overall system complexity while enabling the necessary repair work.
4Ease of repair
If the tower is removed from service for replacement, then complete component replacement can be performed, but the service disruption increases
Solution Approach 1:
The invention employs dynamic temporary support structures that can be quickly installed and adjusted during the tripod replacement process. These dynamic supports allow the tower to be maintained in service or returned to service rapidly after the tripod is replaced, minimizing the time the tower is out of service and reducing overall disruption to utility operations.

AI summary
The disclosed technology includes temporary support structures for use in the repair of a transmission tower. A typical transmission tower includes a tripod that receives the load of the tower and distributes it to piles embedded in the ground. A temporary support structure can temporarily remove the load of the transmission tower from the tripod to enable removal of the tripod and installation of a new tripod. A temporary support system can include a bearing platform system attachable to piles of the transmission tower, a bearing frame supported by the bearing platform system, a lifting system supported by the bearing frame, and a flower pot adapter configured to attach to a portion of the transmission tower, and the temporary support system can thereby be configured to remove the load of the transmission tower from the tripod of the transmission tower.
