Ivoz-Ramet lock

Construction of a lock (length: 225 m, width: 25 m and a 4.5 m lift) whose characteristics are the following:

• located at the same place as an existing lock (to be demolished) with difficulties of accessing the building site;
• set up between a 136 m x 16 m lock that has to go on working and a movable dam;
• incorporation of a hydro-dynamic screw turbine;
• construction of cylindrical sheet pile gabions to be used for the building excavation.

The road access to the new lock and to the new control building is made possible by a 33 m long movable bridge.
