Floods in Venice led to the design of mobile barriers at the mouth of the lagoon to protect the city from high water levels. Approximately 3,000 people are involved in this project which costs 5.4 billion euroswhich has the completion in 2014.
“Once completed, the system will protect Venice from high water levels by more than three meters”says architect Flavia Faccioli the Venezia Nuova Consortium, which brings together 50 companies involved in the project.
“Today we are on track. We have already works worth three billion euros and will perform the first test in July, “said Faccioli.
The 78 giant barriers will be divided into four sections, located next to three holes communicating with Adriatic Sea. These will be placed into some huge vats placed on the seabed. When sea levels will rise, pressure will pump air into the barriers that will rise, and will block the flow of tides.
Once the danger has passed, the air will be removed and the barriers will be filled with water and will descend on the seabed.
“We build 11 container simultaneously, “says Enrico Pellegrini, chief engineer of the construction site. special cement and stainless steel were used to create beams of 60 feet wide and 27 feet high.
“The biggest beam weighs 22,000 tonnes and will be transported with some special designed cars for such operations. Each will be capable of lifting 350 tonnes, equivalent to a Boeing 747 ” Pellegrini continued.
It will take three days for a system “syncrolift” be able to transfer vats from the seabed. “It is a remarkable project, one of the most important in Italy and the world”says the mayor of Venice, Giovanni Orson.
Venice city officials, which sank about 23 inches in the last century, hopes that this project, called “Moses” will help to protect buildings and save the markets from flooding.
