Hydraulic Culverts and Bridges
When designing a culvert or bridge over a river, stream, or watercourse, a flow analysis must be conducted, and cross-sections that allow free water flow should be selected. If the water velocity is high and the risk of erosion is significant, a steel arch solution based on reinforced concrete foundations should be used instead of fully circular steel structures. The riverbed can be reinforced with stones or concrete slabs. If aggressive water conditions are expected, the steel arch can be protected with anti-corrosion paint layers up to the "designed high water level."
With a total of 650 different steel cross-section types, the hydraulic area and other technical details determined during the project are used to select the appropriate cross-section type, which is then prepared for production.
