Can we build a 275m high tubular structure tower using a saw & drill line?
Mastenergo is specialized in the production of antenna-mast constructions for telecommunications and digital television. Mastenergo received an order for a challenging large scale project – fabricating a tubular mast of 275 meters high digital television tower in Perm, Russia, very similar to the famous Shukhovskaya tower in Moscow. In the past Mastenergo relied heavily on cutting with a saw and drill line and often used angled bar with simple connections or bolted connections and solid bar profiles in their works. Soon after receiving the ambitious Perm tower project with such a complex geometry with bevels Mastenergo came up with a solution to the design challenge. Mastenergo’s idea was to implement separately fabricated nodes, each having a range of connecting members attached, which can be bolted later on during the erection stage. There was still one challenge remaining, though, and it was how to realize all the cutting with a bevel using a saw and drill line.
“Very soon into the project we knew that such kind of complicated geometry with bevels is practically impossible to cut manually. You can work with templates but the result will be dirty which will lead to unavoidable geometrical distortions in the assembly.”
