New engineering designs: Scottish case study
Project to renovate and link two canals in Scotland
Historical background
- 1790: opening of the Forth and Clyde Canal (Scotland's 31 canal)
- 1822: opening of the Union Canal
- The two canals allowed boats to cross the 32 part of Scotland
- Locks (steps) connected the two canals near Falkirk
- 1842: competition from a new 33
- 1930s: the locks were demolished
Millennium project
- Aim: to improve Scotland's 34
- The long-term goal -- to strengthen the Scottish 35
- Involved restoration of the two canals
- Problem: one canal is 35m lower than the other
The Falkirk Wheel (a mechanical lift)
- Completed in 2002
- Two large tanks are attached to the ends of an arm
- The tanks are designed to remain in a 36 position
- A boat sails into each tank
- The weight of the tanks with their contents is always 37
- Little energy is needed to rotate the arm
- Visual quality -- resembles a 38
Manufacturing
- All the parts were constructed off-site
- 1,200 tonnes of 39 were used
- Joints were bolted and welded to reduce the effects of 40
