The Diagonal Lock is designed as an alternative to a traditional flight of locks, connecting the canal at the summit of an incline to the canal at the base.
The concept is based on the construction of a watertight, concrete tube built on the incline
- allowing boats to float securely inside the tube as the water level is varied via a system
The proposed design is inherently simple, consisting of 4 key components - click the links below for details.
The Diagonal Lock - Overview
- Narrow boats access the summit via a traditional lock gate.
- The boats enter the lock tube and are secured to the floating bollard.
- Engines are turned off, and boaters can then disembark if they wish.
- The water is pumped out of the lock tube into side pounds, enabling the boats to descend into the tube.
- When the boats reach the base of the lock tube, the bottom gate is opened.
- Boaters embark at the base, the boats are untied from the floating bollard and can continue their journey on the canal.
- The process is reversed for boats ascending from the base to the summit.
Commercial & Technical Viability
The Diagonal Lock technology has been assessed by various technical and research organisations, resulting in the following conclusions:
- The key components of the Diagonal Lock utilize standard construction technologies which would make best use of precast solutions - this increases the speed and ease of construction. One Diagonal Lock is likely, depending on specific site condition, to be more cost effective to construct than a flight of 4+ conventional locks for the equivalent incline.
- Ongoing maintenance costs will be less than the cost of maintaining a flight of conventional locks.
- The ability to re-use water using side pounds will produce quantifiable environmental benefits.
- The Diagonal Lock will be a powerful focus of interest and generate an economic boost to the local community - through increasing tourist numbers and attracting investment into the area.
