Huntons won the contract to design and build two sets of lock gates to be used as flood barriers as part of a scheme to protect Derby City Centre. Ordinarily the Markeaton Brook flows through Derby City and into the River Derwent, when the Derwent is in flood the water travels back up the Markeaton Brook and floods Derby. These gates are used to stop the this happening and consist of a hydraulically operated set and a passive set to provide dual redundancy in the event of a flood.
The gates were fully designed and detailed in house with structural calculations, mechanical design, corrosion protection design, electrical detail connections and the hydraulics. The gates were fabricated in house along with the ancillary steelwork and pre assembled as far as possible to reduce site installation time.
Huntons were given a tight program by the client and managed to successfully install the gates, hydraulics, and electrical connections and had the gates tested and signed off in 3 weeks which exceeded expectations. This was achieved by using highly trained in house staff experienced in installing lock gates, as well as making up our own hydraulic hoses on site with owned equipment, and two teams of in house core drilling using owned equipment.
