Detailed characteristics

The Manchester Ship Canal was built as a cascading waterway in the metropolitan borough of Trafford. The Mode Wheel locks were built as part of the ship canal in the late 19th century and the water level is maintained by individual locks on the stream. The construction of the project was carried out under regular engineering and H&S supervision by the developer and the UK’s Catchment Management Organisation for the area. For the safety of our workers when moving around the site, they were fitted with flotation vests due to the strong river flow in the immediate vicinity throughout the entire duration of the project.

Detailed characteristics

The MW hydroelectric power plant is equipped with a Kaplan “Z” type turbine consisting of a steel intake tube between the concrete inlet section and the engine station / distribution station. The steel inlet box to the engine station is set into a reinforced concrete structure bonded to the side walls of the original structure. There are 2 intake gates at the inlet to control the flow level and to close the building in case of inspection. To securely anchor the gates, a reinforced concrete structure was built to spacing the perimeter walls of the lock structure.

Engine and electrical substation building rebuilt in scope of new concrete slab and concrete lintel to transfer loads from the top structure and allow for demolition of portions of the north wall. Reinstatement work was carried out on the ceiling and external structure of the existing building.
