Excavator-mounted cutting attachments have become established in tunnel projects of the Austrian construction group PORR and in other construction companies. The wide range of applications is carried out with both standard and special cutters. In some cases, even excavation of the tunnel is carried out using cutting technology.
In soft rock, this offers an advantage over blasting, because the bedrock is not damaged by vibrations. Moreover, numerous other operations in tunnel construction and rehabilitation are made possible by excavator-mounted cutting attachments.
Cutting technology is playing an increasingly important role in the tunnel projects of the Austrian construction company PORR. It is currently also being used for a major infrastructure project in Poland. PORR has been commissioned with the planning and construction of the 16 km long section III Bolków – Kamienna Góra of the S3 motorway.
In future, the S3 will form one of the three pillars of the Polish road network from the north to the south, alongside the A1 and the S19, and will connect the Baltic port of Swinoujscie with the Czech Republic and Austria. One of the most complex …
