Prefabricated assemblies constituting barges are linked together to form a landing stage for boats. Vertical columns are attached to a ballast tank to allow the height to be controlled to allow vehicles and machinery to be landed. An upper deck (5) is mounted on float tanks (1-4) to form a track for traffic. At the corners of the barge are columns (10) which slide in vertical tubes (9). These have feet (12) at the bottom which are welded to a ballast tank (13) containing lateral cylindrical tanks (14, 15) and a central tank (16). These tanks are divided into reservoirs which are connected to ballasting equipment in the columns. This allows the ballast to be pumped out or allowed to flow in via electrovalves. Anchoring is provided by chains (43) attached to the columns and to anchors. |
