Bottom horizontal shaft steel dam

The bottom-hinged steel weir (bottom-hinge-driven flap gate) is a new type of hydraulic structure primarily used for river regulation and water control. It features bidirectional water retention, stepless water regulation, and concealed flood prevention functions.
Structural Composition
It mainly consists of the gate body, drive shaft, hydraulic system, and civil structure. The gate body is made of steel and coated with an anti-corrosion layer to extend its service life. Its opening and closing mechanism allows for 0-90 degree rotation via the hydraulic system, enhancing durability through the use of cast steel hinge seats and self-lubricating bearings.
