Amphibious vehicle for bridging a water-filled opening

A vehicular structure for bridging a depression, the vehicular structure including:

• first and second amphibious vehicles linked to each other, wherein each amphibious vehicle includes
• a self-propelled rolling base having wheels on an underside of the vehicle for driving the vehicle on firm ground along a longitudinal axis of the vehicle;
• first and second hinged assemblies that may be folded and unfolded, each hinged assembly including a caisson, a float, and a ramp successively hingedly connected to each other, in that order, so that the caisson, the float, and the ramp can be stored in a Z-shaped configuration, with the caissons hingedly connected to the self-propelled rolling base, the first hinged assembly, when folded in the Z-shaped configuration, being stored on a top side of the self-propelled rolling base, and the second hinged assembly, when folded in the Z-shaped configuration, being stored on top of the first hinged assembly, wherein the first and second hinged assemblies are deployed by being partially or fully unfolded in directions transverse to the longitudinal axis of the vehicle for bridging the depression;
• and
• a deployment device deploying the second hinged assembly on a first side of the rolling base before beginning to deploy the first hinged assembly on a second side of the rolling base, and deploying the first and second hinged assemblies in a plurality of deployment configurations, wherein,
• in a first deployment configuration, the caissons are unfolded from and are transverse to the longitudinal axis of the vehicle, the float and the ramp of the first hinged assembly are unfolded, with the float extending outwardly with respect to the vehicle from the corresponding caisson and the ramp extending outwardly with respect to the vehicle from the corresponding float, and the float and the ramp of the second hinged assembly are folded and underneath the corresponding caisson, facing in the same direction as the underside of the vehicle, and
• the first and second vehicles linked together are deployed in the first deployment configuration and are linked at respective floats on sides of the first and second vehicles at which the respective ramps are folded and underneath the ramps that are linked.
