Flood Control International was recently engaged by the Environment Agency in the UK to modify a number of old flood gates that were ineffective at Stonely UK.
The gates had been supplied in the 1990s by another company, and were ineffective in recent floods.
Flood Control International’s innovative solution was to change the way the gate sealed by introducing a lift and lower hinge that meant that sealing was aided by the weight of the flood gate. All seals were replaced as well as the modifications to the hinge mechanism, and now the flood gates are 100% effective, at a fraction of the price for new flood gates that would have been required had the existing ones not been modified.
The oil depot at Buncefield has been completely rebuilt after its devastating explosion in 2005.
Flood Control International was selected to design and install five oil containment gates for the entrances to the site.
Strict limitations on operational requirements and minimal allowable leakage rates meant that new seals had to be developed and automated gate operation installed as two of the gates will be constant access entrance / egress gates.
Both sliding and lift-hinged swing gates were designed, up to 10 metres wide and 2.85 metres high.
Flood Control International has just completed design and fabrication of some new sliding flood gates for a project in New Zealand.
The gates are to protect a town by closing off a roadway 21 metres wide and 2.7metres high (69ft x 9ft).
The twin flood gates will replace an existing demountable flood barrier which, due to its size, requires a large amount of manpower and time to install in advance of a flood.
As the road is a busy highway, the time closed off needed to be minimised. Also, there could be no step or trough to guide/ support the gate due to it being across a highway, and the possibility of any trough filling with debris/ ice/ water.
The two leaves of the flood gate are winched horizontally into position and then lowered on their wheels to form a fully watertight barrier.
Swing-out braces on the back of the flood gate locate into the groundbeam and are supported on the existing concrete foundations from the demountable flood barriers, thereby saving the need for extensive excavation and concreting works to support such a massive gate with high flood loads.
