A box culvert is a reinforced concrete structure with a rectangular or square cross-section, used to convey water beneath roads, railways, or embankments while maintaining surface traffic continuity. It can be constructed as cast-in-situ or precast units, with precast box culverts commonly used due to better quality control, faster installation, and durability. Structurally, a box culvert consists of a top slab, bottom slab, and side walls designed to resist soil pressure, traffic loads, and hydraulic forces.
WIKA Beton's box culverts are designed to accommodate different service conditions: Class A for light pedestrian loads, Class B for heavy-duty truck loads, and Class C for standard duty truck loads. This classification ensures that the selected box culvert meets the required structural capacity and safety performance based on its intended application, such as pedestrian areas, urban roads, or heavy traffic corridors.
