Bidirectional Water Retention Capacity
The gate can rotate around the hinge pin to realize bidirectional water retention for upstream and downstream, adapting to complex flow conditions and eliminating the limitation of conventional dams which only retain water on a single side and are susceptible to the impact of downstream water levels.
Concealed Engineering Design
When the gate is laid flat, it is flush with the river bed and hidden under the water surface, without obstructing flood passage channels and ship navigation.
Self-adaptive Sediment Discharge Function
Strong water flow generated during gate opening and closing scours sediments. Combined with bottom discharge holes, the gate can automatically remove silt, branches and other floating debris.
