Factory-direct hydrostatic solutions engineered for municipal subways, power utility gates, and commercial underground parking structures.
As extreme hydrometeorological events increase in frequency, industrial civil asset managers are moving away from manual deployment toward hydrodynamic self-activating barrier systems.
Eliminates reliance on external power grids, backup diesel generators, electric motors, or water level sensors that are prone to short-circuiting during tropical storms.
Reinforced extruded aluminum alloy profiles (6063-T6) engineered to sustain heavy vehicular traffic, including 40-ton logistics trucks and emergency vehicles.
The moment surface run-off enters the embedded bottom reservoir chamber, natural buoyancy automatically pivots the flood wall upward to lock against hydrostatic forces.
Engineered in Nanjing and deployed across multi-national infrastructure projects.
Deep technical specification guide for structural engineers, EPC contractors, and municipal procurement directors.
The entryway automatic flood barrier operates on fundamental Archimedes principles and hydrostatic leverage. Designed flush with surrounding pavement during dry periods, the system comprises a ground-embedded structural frame basin and a high-strength rotating barrier panel.
As storm surge or flash flood water flows across the threshold, water enters the bottom basin through intake grates. As water fills the basin, buoyant force lifts the front edge of the barrier panel. As the water head rises, hydrostatic pressure forces the panel firmly against vertical side-frame seals, creating a watertight barrier that scales dynamically with water height.
Watertight integrity depends on elastomer compression dynamics under continuous hydrostatic pressure. Our barriers utilize custom-extruded EPDM (Ethylene Propylene Diene Monomer) composite gaskets combined with high-grade NBR rubber seals.
The seals feature multi-lip profiles that self-tighten as water pressure increases. Resistive to UV degradation, ozone, temperature fluctuations (-40°C to +90°C), and chemical runoff, these seals maintain continuous performance through a 20-year service lifecycle.
