76mm TR Thread Self Drilling Anchor System Rock Grouting Bar TR76/1900
Features
TROPE TM Drilling hollow bars is an unique anchoring system and is today’s answer to the increasing demands of the tunnelling industry and ground engineering for safer and faster production. The system provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil.
Stipulated for verification of permanent corrosion pro_x0002_tection. Such a crack width cannot be achieved by drilling rods with rope threads, e.g. R32 or R38 (to ISO 10208 and ISO 1720).
