Description

Technical Field

[0001] The invention relates to a universal foundation, in particular to a guy tower foundation used for a temporary guy tower of an overhead power transmission line. Background Art

[0002] Overhead transmission lines are the physical carriers of electric energy transmission. Transmission towers are differentiated by the support method used to maintain structural stability, and can be either free-standing or guyed. In the event of a tower collapse or rerouting on a conventional transmission line, emergency repair equipment must be installed for line repairs or transition towers must be erected for line construction. Transmission towers used for these purposes often require modular assembly and reuse. Guyed towers offer a simple structure, a regular appearance, strong versatility, and efficient transportation and assembly. These towers facilitate modular assembly and reuse, making them a popular tower type for line repairs and temporary construction.

[0003] Existing design manuals and specifications only provide materials and structural forms for permanent guyed towers, including precast reinforced concrete, stone, and cast concrete foundations. These materials and structural forms do not meet the requirements for the temporary and reusable use of temporary guyed towers. Temporary guyed tower foundations, such as those in the form of a guyed drum, have dimensions specific to a specific guyed tower, making them less versatile. Some construction workers even use logs or sleepers instead of professionally designed foundations. Furthermore, a separate bearing foundation must be designed beneath the columns.
