A large-section box that combines three segmented precast components with cast-in-place concrete.
■ The FA Box - "Angled Large Box Culvert" is a large-section box that combines three segmented precast components with cast-in-place concrete. ■ By using a segmented structure for the top slab and side walls, it becomes easier to accommodate "angles." ■ By making the precast components into a slab structure and using cast-in-place concrete for the bottom slab, it enables the construction of an economically efficient large box. ■ The use of loop joints to integrate the precast components allows for easier construction and a reduction in construction time.
