With the rainy season coming soon, this customer wanted a faster, more economical alternative to a cast-in-place bridge for their remote Puente Ccalaccapcha stream crossing in Peru. It needed to be easy to assemble, have a low profile for grade requirements and have a wide mouth for optimized hydraulics.
Keeping a low profile and going with the flow
They got all of this in their new 15.83 m (51.93′) Super-Cor Box Culvert from AIL Mining. Four days of assembly. Four days backfilling. And — despite being the largest of its kind in Latin America — a structure that maintains a low profile and goes with the flow.
Large or small, box culverts are the perfect solutions for long-span, low-rise situations with shallow cover requirements. Ours can be made from Ultra-Cor or Super-Cor Structural Steel Plate or corrosion/abrasion-resistant Dur-A-Span Structural Aluminum Plate.
Project success was truly a group effort
This remote project faced a few challenges and the AIL Mining team collaborated with international partners on the project. One team addressed the softer foundation soils with footing design and soil improvements. Gabion-style headwalls and wingwalls with geogrid soil reinforcement were also supplied by others.
