ABSTRACT:
The installation enables an internal waterway to pass through a changing level by means of a water ramp connecting through a channel two water reaches respectively situated upstream and downstream and including basins for the storage of boats awaiting their turn before entering the water ramp. The upstream reach is provided with a tilting gate for the retention of the water, while a pusher provided with a transverse mask retaining a water-wedge on which the boat to be moved floats is movable along the channel to ensure the transfer of this boat from the downstream reach to the upstream reach and vice versa. The retaining gate for the upstream reach is located at a certain distance beyond the upstream end of the water ramp and a second retractable gate is arranged substantially at the end of the water ramp, these two gates bounding between themselves an intermediate horizontal reach, separating the upstream end of the water ramp and the upstream basin.
