A total of three CSS3 EVOs, two of which delivered in April 2021, will be used by the international group of companies consisting of VINCI Construction Grands Projets, Dodin Campenon Bernard, Webuild and Bergteamet, for consolidation work using shotcrete in the ventilation shafts at Avrieux and the service and access tunnels at Modane for the Cross border section of Lyon-Turin railway.
The CSS3-EVO is the latest evolution of a machine that has made shotcrete history around the world and benefits from CIFA's extensive experience on site. Several factors were decisive in the decision to adopt this machine: its extreme compactness during transport, the special configuration of its translating boom which can be opened in very tight spaces but which, once deployed, with its 16-m length, is able to operate easily in tunnels of considerable size, the exclusive dual-axis boom turret which makes it possible to follow the profile of the tunnel by reducing the number of movements of the sections by the operator, the 180° reversible driver's seat so that it is easy to drive in both directions. These features allow the CSS3-EVO to be used both in the exceptionally large underground caverns at the base of the shafts and in the areas chosen for the assembly of the TBMs that will excavate the main tunnel, and in the reduced spaces of the access and connection tunnels.
CIFA's subsidiary in France, Zoomlion CIFA France, has been entrusted with service and aftersales activities by the site management. The configuration requested by the customer to adapt to the operational needs of the site is also particularly rich: a compressor for spraying mounted on board the machine with integrated controls, an electric additive heating system, a rear view camera and an ANSUL fire suppression system with automatic activation. In short, a machine perfectly configured to meet the great challenge of this site, which represents one of the largest underground works under construction in the world. Read the newsletter.
