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).
