Installation of a fusegate
Fusegates provide an alternative solution – with technological and economic benefits – to conventional systems (radial gates, flap gates, inflatable dams and fuseplugs for example). Fusegates provide a modular solution made up of independent units installed side by side on the dam’s spillway crest. The modules are linked by sealing joints, creating a watertight wall that increases the reservoir capacity. The size and type of fusegates varies from project to project in accordance with different needs, allowing them to operate successfully in both normal and extreme conditions (significant wave action, floating debris, ice pressure, earthquakes, etc.).
Because of an inlet-well system that has progressive settings, fusegates overturn in response to very exceptional floods in a controlled, sequential approach.
