Self Drilling Hollow Anchor Bolt Application in Yuxi-Mohan Railway Tunnel

Time:2021-07-12From:This Site

Self drilling anchor bolt can simplify the drilling, grouting and anchoring procedures. The full length of the bolt is fully anchored, and it can provide a certain supporting resistance immediately after excavation, effectively suppressing the loosening and deformation of the surrounding rock, and avoid or slow down the occurrence of disease accidents during construction and use of the project. The use of self drilling anchor bolt and drill bits can ensure grouting layer is at least 20mm, which fully guarantees the durability of the bolts, and is especially suitable for supporting and strength
