But it is not only roads that connect towns, cities, and countries. Beneath us, there are invisible underground junctions: a tangle formed by a web of conduits, cables and pipes. This grid constitutes a real network, like the way our blood circulates around our bodies. They are the lifeblood of a country.
All over the world thousands of construction sites are being built, where trench work is under way to put together new pipelines for the transportation of gas, oil and water. These are often enormous infrastructure projects, divided into sections, often located in isolated places, where it is necessary to build miles of tracks and roads to allow access.
Heavy equipment units follow the site for miles and miles to dig the trenches, prepare the trench bed, install the pipes, prepare the materials to cover the pipes and close the trenches.
