Stoplogs and Sluice Gates

Hubert Stoplogs and Sluice Gates: Essential Tools for Channel Maintenance

A Hubert stoplog or sluice gate is designed to close off and dewater a channel, making maintenance tasks efficient and manageable. These components play a crucial role in the water intake ‘screening train,’ where they enable the channel to be safely closed and dewatered for inspection or repair.

Stoplogs Stoplogs consist of multiple sections that are lowered into the channel as needed. By adding or removing these sections, the desired water level can be achieved using a lifting beam and a crane. When not in use, stoplogs are stored outside the channel in separate sections.

Sluice Gates Unlike stoplogs, sluice gates function as a single unit that can be raised or lowered to control water flow. These mechanisms may be motorised or fully automated for convenience. When inactive, sluice gates remain in their top position.ns outside the channel when not in use, while a sluice gate is positioned in the top position when not in operation.

Stoplogs & Sluice Gates

Custom-Made Hubert Stoplogs & Sluice Gates for Efficient Channel Management

Hubert stoplogs and sluice gates are engineered to provide rapid and secure closure for large inlet channels and pump chambers. Each system is meticulously designed to meet specific project and customer requirements, ensuring a perfect fit and reliable performance.

Stoplogs and sluice gates are key components of water intake systems, typically installed upstream from coarse bar screens, drum screens, or traveling band screens. Their strategic placement ensures optimal flow control and supports the overall efficiency of the screening process.

You can count on our tailored solutions for every water management need.

Water Inlet Closure

The use of stoplogs or sluice gates enables periodic inspection and maintenance of screening systems and pumps. By dewatering the isolated section of the channel, these components create a safe and dry environment for effective maintenance operations.

Design and Construction

Stoplog

Hubert stoplogs are meticulously designed to match the specific water pressure requirements of individual situations. For deep-water applications, stoplogs are constructed in two or more sections for optimal functionality. Seals are mounted on the flat side of the stoplogs to ensure a secure fit, while guides installed in the side walls of the concrete channel provide precise alignment and sealing during installation. A lifting beam and crane are used to place or remove individual stoplog segments with ease. In addition to the stoplogs themselves, Hubert offers storage frames to safely store unused segments. For added durability and protection, cathodic protection can also be integrated into the design.

Sluice gate

Hubert sluice gates are typically installed downstream of a supply line, requiring a slightly different approach to guiding and sealing compared to stoplogs. The sluice gate construction is embedded within the side walls of the concrete channel, ensuring precise alignment and optimal sealing during operation. A sluice gate functions as a single unit that is raised or lowered to regulate water flow. These mechanisms can be motorized and even automated for enhanced efficiency and convenience. The additional lifting and lowering installation is positioned at the top of the channel. Hubert sluice gates are engineered for seamless integration into your water management system, ensuring durability and reliability in all operations.

Stoplog Guide Cleaning System

Hubert offers a specialised guide scraper system designed to remove shells, such as mussels, and other marine life from the grouted stoplog guides. This innovative system efficiently clears away any grown objects from the water, making it easier to lower and raise stoplogs while maintaining the integrity and functionality of the seal.
