Flood gates6/15/2023 The fish-belly gates have the advantage of low losses and are installed protected in overflow chambers. They can be adjusted exactly to the floating-up point by filling counter weight water inside by means of filling and emptying nozzles. The flood gates are designed as floatable fish-belly gates. They are designed with a smooth-opening cover to enable opening for low discharge flows this is achieved by extra weights or the angle of inclination of the flap.īottom-hinged HydroLatch ® flood gates Model HLA-FK can be applied wherever the water level difference is very small. They are designed as rectangular or circular flood gates and can be installed to protect overflow/outfall pipework from surcharging. Our range of flood gates can be installed for standalone flood protection or as multiple structures integrated to form an entire floodplain management solution. The top-hinged HydroLatch ® flood gates Model HLA-HK can be applied wherever there is sufficient head difference. All HydroLatch ® flood gates are project-designed so that the gate cover is light (low resistance = large flow-rate) but heavy enough to prevent lifting by flow velocity. Following apocalyptic floods in 2019, the worst for more than 50 years, the city’s decades-in-the-making, 5.5 billion flood barrier system finally went into action in October. The special Steinhardt ® seal is reliable and durable. ROME The inhabitants of Venice last week heard a sound they were hoping to forget: the wail of the siren signaling a flood tide, or acqua alta. Even if the HydroLatch ® flood gates are flooded, drainage occurs as long as the water pressure in the sewer network is higher. The HydroLatch ® flood gates also allow a safe overflow from combined and stormwater networks during rain. The flood gates work automatically and without electricity. The WayĪll overflow sills, inlets and outlet sewers in combined and stormwater networks can be secured with Hydro-Latch ® flood gates to prevent flooding of the sewer network. Flood Gate Controller Limits energy loss from heavy growth or flooding Fully sealed from insects and the environment Ideal for use near creeks, streams. The warning and reaction times are shorter sand bag barriers and manually-operated valves are time-consuming and labour intensive. Streams and rivers overflow their banks more often, more inten-sively and faster due to large impermeable areas and loss of flood plains. through the sewer, to flood streets and houses. This time, the high tide could have wreaked havoc on the small island, but the barrier system of 78 floodgatesknown as Mosesuccessfully kept Venice’s winding alleyways and historic squares. Flood protection is also necessary underground so that flood water does not come through the “back door“, i.e.
