AUTHORIZATION OF THE MINISTERO DELLE INFRASTRUTTURE E DEI TRASPORTI AND MAGISTRATO ALLE ACQUE - RECORD No. 11196 dated September 20, 2012

The MOSE (MOdulo Sperimentale Elettromeccanico: Experimental Electromechanical Module) is a project intended to protect the city of Venice in Italy, from floods. This project has been carried out by the Consorzio Venezia Nuova on behalf of the Ministero delle Infrastrutture e dei Trasporti (Italian Ministry of Infrastructures and Transport) and of the Magistrato alle Acque di Venezia (Venice Water Authority). It is supported by a “sample” of batching and jet grouting injection plants. Let’s see the details of the project.

On the MOSE’s building site of Lido Nord Treporti (one of the planned sites, together with the ones of Chioggia and Malamocco), they are now carrying out the progressive positioning of the threshold caissons in the trench system, previously dug in the area of Bocca di Lido. The caissons consists in concrete blocks that will support the protection gates of MOSE; the ground consolidation of this installation requires a complex intervention that involves the most advanced technological skills of the company Mantovani Spa, assisted by the project creativity of Metax, engineering division of the company Cima Spa, that offers diversified solutions to the specialized high-profile building industry since 1987.

MOVABLE MIXTURE
We are in the company of Mr. Pasquale Triggiani, qualified technician and Managing Director of Metax division, on the north-east side of Bocca di Lido, in front of the waterway that leads to Treporti. Within this area there are two facilities, which are dedicated to the production of cement mixtures used for consolidation injections into the seabed. In particular, our visit to the building site regards the new JM40PV plant, which runs fully automatically, according to the sum of the weight method.
The role of these facilities is essential, and the construction of the structures was made in a specific way, paying great attention to details, on behalf of the Metax research and development department. “The first system of this kind has been designed with the aim of producing cement mixtures also using sea water, reducing high costs due to the traditional use of fresh water”, explains the industrial expert Pasquale Triggiani. “It is a technology developed in co-operation with the company Mantovani Spa and implemented after a series of successful tests, already in the first start-up years of the MOSE building site, at the end of 2004.
