Product: Fish Baffles
Application: Department of Transport and Main Roads
Sectors: Infrastructure; Government
Fish baffle in culverts is essential for the continuous movement of fish and organisms through the waterways. They are installed in various ways depending on the species living in the area. Master Steel aided the Department of Transport and Main Roads in fabricating the fish baffles that are fitted in the box culverts at various locations across Queensland.
For the project, the fish baffles are set vertically, both on the upstream wingwall and inside the culverts. Safety rails are provided for the culverts with fish baffles that are near pedestrian activity. The height of the fish baffle on the wingwall closest to the culvert opening matches the height of the baffles installed inside the culvert. Meanwhile, the baffles at the end of the wingwall is limited to 30mm below the wingwall height. The baffles protrude by 150mm horizontal into the flow.
The flat bars used are Grade 300 to AS/NZS 3679.1. These are hot-rolled structural steel bars and sections that are suitable for general structural and engineering applications.
All steelworks for the project are fabricated in compliance with the requirements of MRTS78. The structural steel welding also meets the requisites of AS/NZS 1554.1, which outlines the specifics for welding of steel structures made up of combinations of steel plate, sheet or sections. The fish baffles are attached on the wingwall and inside the culvert at intervals using ferrules which are filled with natural silicone before galvanising.
Master Steel delivered 528 baffles with varying specifications for the size of the culvert as well as 72 various items, such as hold down brackets and bolts with nuts, to affix the baffles into place.
