| Zusammenfassung: | Construction of an underground chamber, for example a tunnel, involves drilling, blasting and cutting. For each newly blasted section, a calculation is made, immediately after blasting, to determine the total number of reinforcements needed for the section in question. These reinforcements are then integrated in the normal advance cycle. This prevents the development of unnecessary deformations and at the same time permits improved safety and greater rationalization of the work. |
