Concrete pipes are a common construction tool, but architects across the world are also using the pipes as inspiration for unique structures. For example, Techne Architecture + Interior Design deployed concrete pipes as a design motif for the Prahran Hotel in Australia.
Urban infrastructures provide comfort to inhabitants and mitigate the risks of disasters such as flooding. Underground systems specifically conceal urban infrastructures from public view and are configured as real mazes under the streets.
The distribution of drinking water, urban drainage, sewage, and even electrical wiring and fiber optics in some cases, pass under our feet without us noticing. To this end, the industry developed precast concrete parts for about 100 years that provided construction speed, adequate resistance to force, and durability against time.
Concrete pipes with circular sections, in many diverse diameters, are perhaps the most used conduits and are ubiquitous around the world. But there are also those who use these apparently functional elements in creative architectural contexts as well.
Concrete tubes are rigid ducts that may or may not contain metallic reinforcement according to their structural demands. Their geometry allows them to properly support the weight of the earth and other structural loads.
These parts are dimensioned and specified according to flow, specificity of program (rainwater or sewage / effluent conduction), and mechanical resistance. In architecture, perhaps the first use of such elements that comes to mind is in playgrounds. A concrete tube is, in itself, a fun toy.
