Почему Нефтепровод Аляски не может касаться Земли

Why is the Alaskan oil pipeline built on piles? 🛢️❄️ The engineering mystery of permafrost Why wasn't the Trans-Alaska Pipeline buried like all the other pipelines in the world, but raised into the air on tens of thousands of steel supports? Why doesn't it run straight across Alaska, but in a strange zigzag? And what are those mysterious "radiators" sticking out from each support? In this video, we examine one of the most intricate engineering structures on the planet. You'll learn why the oil inside the pipe flows hot, how permafrost nearly ruined the entire project, and how a simple temperature difference causes the supports to freeze the ground without a single motor or wire. You'll also learn how this pipeline withstood a powerful earthquake that struck directly beneath it without spilling a drop of oil. A true story of engineering ingenuity, battling the Arctic elements, and solutions that were decades ahead of their time. ❓ Did you know that oil in the pipeline is hot?
