Costruzioni Alfredo La Posta company, based in Sora, Italy, has tested
Simex TFC 400 cutter head with continuous cutting in a construction site located in Venarotta, in the province of Ascoli Piceno. The
rock face was mainly composed of tuff, a compact and abrasive rock, with silica veins inside it.
The operation was twofold: on one hand the
excavation of a trench approximately 1.60 m (62 inch) wide by 1.20 m (47 inch) of depth, for the subsequent laying of sewers; on the other hand,
milling on the vertical rock wall for consolidation purposes (micro support poles had already been positioned).
