Structural plate pipe culvert is rapidly become an alternative of culvert, bridge and underpass construction, for its high strength and affordability and easy handling. Round pipe is a basic shape; it also has different versions such as vertical and horizontal ellipse, pear shape. All these shapes have their own characters and the most suitable applications.
Round pipe is the most common and versatile shape. All the plates share the same radius. Its maximum span can reach 8.02 meter. It is primarily used as culverts, sub-drains, sewers, service tunnels, but also appropriate for storage bins, tunnels and bridges.
Pear shape features wide at top and narrow at bottom. This unique shape is very suitable for underpasses and grade separations. Sometimes, it is also employed as storm sewer and railway tunnels. It is 8.56 meter wide at its maximum and total rise can reach 8.61 meter.
Ellipse shapes are ideal for underpasses, recovery and service tunnels. Horizontal ellipse prefers to vehicular underpasses, multi-lane, grade separations and tunnels, while vertical ellipse is better for single lane vehicular and railway underpasses.
Although they are different in shapes, they have one point in common: they are assembled by structural plates. Unlike concrete constructions, they have lightweight, short delivery time, economic cost as well as aesthetic appearances.
Round pipe culverts are polymer coated for 100+ years of service period
