Design for overhead installation of large-diameter pipelines?
Thread Content
Who has experience in the design for overhead installation of large-diameter pipelines? You can share it, right?
Fictional? Utility tunnel? Large diameter? How old?
Pay attention to stress; nothing else seems to be a problem
Along the route, there are basically low-type piers; for passages, high-type piers are used, with a diameter of DN1200, for conveying compressed air at normal pressure since the pressure is not high.
