Stoplog & Sluice Gate

A Hubert stoplog or sluice gate closes & dewater the channel for maintenance

Stop logs and sluice gates are essential parts of a water intake ‘screening train’, because it makes it possible to close and dewater the chanel for maintenance.

A stoplog normally consists of a number of sections which are lowered into channels. During operation, these segments are added or removed as required to achieve the needed water level  by using a lifting beam and a crane.

A sluice gate is normally raised or lowered as one piece, whereby lifting and lowering can be motorized and possibly automated.

A stop log is stored in sections outside the channel when not in use, while a sluice gate is positioned in the top position when not in operation.

Hubert – Water Intake Systems

Hubert is specialized in water intake systems for cooling, drinking and process water

Over the years, Hubert has built up a great reputation in supplying water intake systems, used for mechanically clean water extracted from the sea, rivers or lakes. This filtered water is applied for cooling and process water. Hubert supplies engineered, made-to-measure automated screening machinery & complete screening systems. We supply complete complete ‘screening trains’ including all additional equipment, like controls and cathodic protection. See also Markets & Applications

We are active in both new construction (EPC) projects and renovation & optimization of existing water intakes.

Stoplog & Sluice Gate

Hubert stoplog & sluice gate systems are always made-to-measure

Hubert stoplogs & sluice gates permit rapid and secure closure of very large inlet channels and pump chambers. Stoplogs & sluice gates are always designed according to project and customer specifications.

A stoplog or sluice gate is typically installed in water intake systems upstream from coarse bar screens and drum screens or travelling band screens.

Shutting the Water Inlet

Using stoplogs or sluice gates makes periodic inspection and maintenance of screening systems and pumps possible by dewatering the separated part of the chanel.

Design & Construction

Stoplog

Hubert stoplogs are constructed to match the expected water pressure in individual situations. For deep water, the stoplogs are made in two or more sections. The seals are mounted on the flat side of the stop logs. Guides are installed in the side walls of the concrete channel to ensure optimum sealing and installation. A lifting beam & crane is used to place and remove a stop log (segment). Hubert also supplies a storage frame. Naturally, cathodic protection is also possible.

Sluice gate

Hubert sluice gates are often placed after a supply line and therefore guiding and sealing is done slightly differently than with stop logs. Obviously, a sluice gate construction is installed in the side walls of the concrete channel to ensure optimum sealing and installation. A sluice gate is normally raised or lowered as one piece, whereby lifting and lowering can be motorized and possibly automated. This additional installation is located at the top.

Standard Dimensions & Materials

Stoplog

  • Width up to 6 m
  • Height up to 12 m
  • Materials can be coated carbon steel, stainless steel and exotic alloys (a variety of (super) Duplex grades)

Sluice Gate

  • Width up to 5 m
  • Height up to 4 m
  • Materials can be coated carbon steel, stainless steel and exotic alloys (a variety of (super) Duplex grades)

Stoplog Guide Cleaning System

Hubert supplies a guide scraper system that removes shells (like mussels) and other marine life from the grouted stop log guides. The system retrieves grown objects from the water and ensures that lowering and raising a stop log is easier again and that the seal continues to do its job.
