Inefficient supporting effect in the tunnel by small pipe? Self-drilling anchor bolts (SDA) solve problems at once

Time:2021-11-19From:This Site

Due to the high hardness of the conglomerate layer, the small pipe cannot be penetrated, resulting in an unsatisfactory grouting effect and continuous water leakage in many places in the tunnel. In order to ensure normal construction, after many tests, the self-drilling hollow grouting anchor rod was finally selected for support.

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
