The shells can be stacked to form abutments or retaining walls, featuring cellular voids that serve as permanent formwork for insitu reinforced concrete, thus enhancing structural strength.
Key features include a modular design based on a 2x2m grid, available in various geometric configurations to accommodate different heights and widths
The structural functionality is primarily provided by insitu concrete cores, with monolithic connections at the pile cap and top diaphragm for integral bridges. The shells are reinforced to control cracking and withstand temporary loads during installation, equipped with rubber gaskets and grouted dowels for stability.
This modular approach facilitates rapid construction and cost-effective solutions, yielding substantial programme and resource savings compared to traditional methods. Adaptability is achieved by adjusting unit dimensions and foundation levels to suit different bridge spans and crossfalls.
Overall, the system streamlines construction, enhances durability, and provides flexibility in bridge design.
