The task was to design rail-mounted movable formwork to pour the walls to the spillway. The formwork had to be adjustable so that as the formwork travelled up the spillway slope the wall:
- became taller
- stayed the same thickness at the top
- became thicker at the bottom
- maintained a vertical inside face
The stresses on the formwork increased as it travelled further up the spillway. It was a great piece of design work. From this project I went on to design a slipformer that was used to concrete-line dam walls. The moving formwork and screed had to span 12 metres, convey the wet concrete, spread it and vibrate it as the whole piece of equipment moved up the inclined wall. So much fun!
Well-designed aids to manufacture can increase productivity or efficiencies enormously – and keep a company competitive.
