The object of this contract is precisely the restoration of the Melide-Grancia Tunnel on the Lugano Sud - Mendrisio motorway, with a restoration of the main structure of the vault of the tunnel. Restoration carried out by laying two prefabricated concrete half-shells, which function as a permanent formwork, the back of which is then realized with sprayed concrete, to achieve the new supporting structure of the vault.
Historic collaboration with the Pizzarotti group
The methods and timing of work as well as the need to have a capillary control on the quality of concrete and the expected use of 9,000 cubic meters of concrete type SCC, among others, led Pizzarotti SA to reject the hypothesis of buying concrete from third parties, preferring self-production on site with its own batching plant.
The procurement of the Pizzarotti SA has therefore been activated proposing a commercial tender to the main manufacturing companies of batching plants on a national and international level with strict technical operating conditions to fulfil.
Among these companies was MCT Italy, which can boast a historic collaboration with the Pizzarotti group, especially with regard to the precast division at the three operating sites of Ponte Taro (PR), Lucignano (AR) and Melfi (PZ).
In fact, this batching plant perfectly combines the flexibility and manageability of a mobile plant, with high levels of productivity and control of the concrete, all combined with a minimum footprint of the plant, necessary as a basic requirement for Pizzarotti SA, given the limited availability of space.
The innovative configuration encloses the entire plant in two 40‘ containers, certified by Rina, which also makes transport on any means (truck, train, ship) extremely easy and it allows an absolutely fast assembly and commissioning. All of this makes the MCM Bellatrix H batch plant the ideal solution for temporary and fast-moving construction sites. The planetary mixer type MAV1500/1000 makes the plant extremely versatile and suitable for the production of a wide range of concrete for all the different classes of consistency including concrete with steel and polypropylene fibres, as well as GRC.
The batching plant MCM Bellatrix H is managed by the Compunet software which represents the most technological part and makes operation particularly easy, allowing customizable production reports as well as the bidirectional exchange of input and output data with the customer’s accounting system.
Thanks to these features, the MCM Bellatrix H mobile system also perfectly meets the requirements of Annex A to Law 11 December 2016 n.232, which in the framework of the new national plan „Transition 4.0“ allows to take advantage of a tax credit in 3 years equal to 50% of the value of the asset purchased.
The planetary mixer is equipped with automatic washing system that can be activated either from the operator’s cabin or directly from the control panel next to the mixer.
Very satisfied with the batching plant
For this project, a mixer of type 1500/1000 was selected for the production of up to 40 cubic meters of high-quality concrete per hour. The concrete is discharged and transported through truck mixers. Ing. Luca Cellini, Sales Manager of MCT Italy, who was involved in the batching plant proposal and sale, said: „The MCM Bellatrix H mobile batching plant is the ideal solution for temporary construction sites. In fact, it perfectly combines flexibility and rapidity of installation with a high-quality control of the concrete. We are extremely proud to have renewed the collaboration with the Pizzarotti Group in a country like Switzerland that represents a historic market for MCT Italy“.
