CONTACT US SERVICES Rock reinforcement The concept of rock reinforcement includes, among other things, rock anchoring with a bolt or net, shotcrete and in some cases grouting. These techniques are used when rock chambers and tunnels are reinforced during the construction phase or in connection with continuous maintenance. CONTACT US HOME / SERVICES / MOUNTAIN / ROCK SUPPORT Rocks have a natural fracture system, which requires rock reinforcement Crossing cracks can give rise to intermediate hazardous wedges in tunnel roofs or walls. By anchoring these wedges with rock bolts in solid rock, they are prevented from falling down and causing damage. A geologist maps the rock and determines how long bolts are required, direction and at what distance these should be mounted in the rock in relation to each other. Reinforce with shotcrete Sprutbetong förstärker berget genom vidhäftning, valvfunktion och murbruksverkan och kan samverka med bergbultar. Efter bultning sprutas vanligen betong för homogent utseende och låga underhållskostnader. Även ett tunt lager sprutbetong ger en avsevärd förstärkning. Sprutbetongens tjocklek beror på bergets kvalitet, antal sprickor och tunnelns eller bergrummets användning och kan variera mellan ca 30 mm till 300 mm. För att förstärkningen ska ha en god beständighet bör sprutbetongens tjocklek inte understiga 50 mm. Förankra berg med nät Reinforcement with nets takes place mostly in cuts, but sometimes tunnel roofs with nets are also reinforced. On mountain slopes, the net is anchored with bolts at the crest, at ground level and if necessary in between. The net prevents loose rock from falling down and causes damage to, for example, a person, car or train. Nets can also be fitted to protect against the fall of ice cubes; then the net is spaced from the rock with extended bolts. Reference project Click on one of the boxes to see reference projects.
