<p>An integral formwork system for the construction of pits (20) for loading ramps (10), comprising a set of appropriately reinforced sheet metal panels, piping and sections, bolted to each other; in particular, the formwork is of disposable type, built with specific construction, lightweight, resistant, and compact in size, in order to permit single operation casting for paving (PCL), from the pit level of the formwork without the need to provide special and expensive connecting structures such as flexible joints. Moreover, the system in question also permits the construction of overhang ledges (23) without special moulds; when work is completed, these overhang ledges (23) are able to bear the weight of the loading ramp (10) and the vehicle positioned on it (17).</p> |
