The Ultimate Guide to Choosing crest gates

At BIC, we specialize in the design and manufacturing of spillway crest gates, critical components for dam structures. These crest gates are engineered to manage and control the release of excess water, ensuring the safety and integrity of the dam while preventing uncontrolled overflow. Spillway crest gates are positioned at the crest or top of the spillway, serving as the primary regulatory mechanism for water flow.

Types of Spillway Crest Gates

◆ Radial Gates: Hinged at a central point, these gates rotate to open or close, providing effective control in spillways.

◆ Vertical Lift Gates: These gates move vertically, allowing for the control of water flow and are commonly used in large dams.

Operation & Maintenance

Spillway crest gates can be manually or automatically operated, with options ranging from mechanical systems to advanced remote-controlled automation.

Regular maintenance is crucial, involving inspections for wear, corrosion, and mechanical issues, ensuring the gates' reliability during high water flow events.

Safety Features

Our gates incorporate safety features such as backup systems, sensors, and monitoring devices to enhance operation reliability and safety.

Spillway crest gates are indispensable in various dam structures, serving multiple applications:

◆ Preventing Flooding: By controlling water levels, these gates prevent downstream flooding during heavy rainfall or rapid snowmelt.

◆ Regulating Water Levels: They maintain necessary water levels for environments like the San Antonio RiverWalk, where aesthetics and functionality must be balanced.

◆ Emergency Release: In emergencies, these gates provide a controlled release of excess water, protecting the reservoir and downstream areas.

Tips for Choosing the Right Spillway Crest Gate

◆ Consider the Environment: The choice between radial and vertical lift gates should be based on the specific environmental conditions and the scale of the dam.

◆ Evaluate Operational Needs: Determine whether manual or automated operation best suits the dam's operational requirements.

◆ Regular Maintenance: Always ensure a maintenance schedule is in place to prevent malfunctions and maintain the effectiveness of the gates.

Maintenance: A Key to Effective Spillway Operations

Proper maintenance of spillway crest gates is essential for preventing flooding, property damage, and environmental impact. It also addresses health and safety concerns by ensuring the spillway functions correctly, protecting both people and the environment.

The Bascule® Gate design features a flat plate that is reinforced with vertical and horizontal members and is fitted with a single torque tube across the invert. The torque tube is supported by bearings along the invert edge of the gate. A hydraulic cylinder, cable drum hoist, or electric motor-driven cylinder is attached to the arm of the gate with a stem for operation.
