Recently, many regions have been hit by heavy rainfall. The 90cm flood-proof weapon installed in the garage of a community in Huizhou, Guangdong – the hydrodynamic automatic flood-proof gate for construction, successfully played its role during the heavy rain. All 3 openings successfully blocked water, effectively preventing rainwater from backflowing into the underground garage within the height of the equipment.
It is understood that when the rainstorm came, the water level around the community rose sharply, and the rainwater rushed towards the garage entrance. At this critical moment, the hydrodynamic automatic flood-proof gates installed at the 3 openings of the community all automatically rose to block water under the buoyancy of the water flow. The entire process required no electricity or manual operation, building a solid flood control barrier for the garage at the first time.
The hydrodynamic automatic flood-proof gates in the community’s garage have been in service for 6 years since their installation in 2019 and have always been in a state of combat readiness. This time, they responded quickly to block water during the rainwater backflow, which not only effectively reduced the disaster degree of the garage but also proved that the Junli hydrodynamic automatic flood-proof gates are still reliable and effective after long-term use and can stand the test of time.

The hydrodynamic automatic flood-proof gate is developed by Nanjing Junli Technology Co., Ltd. Its working principle is simple and efficient, requiring no electric drive or manual opening. When the water level rises, the gate automatically flips to an upright state by virtue of buoyancy to block floodwater from backflowing into the garage; when the water level drops, the gate automatically falls back and finally lies on the ground, without hindering the normal passage of vehicles. At present, the flood-proof gate has been widely used in underground construction projects such as subways, underground garages, shopping malls, and pedestrian crossings in many cities across the country, with a 100% water-blocking rate!
