Increasingly used for Slope Stabilizations - self drilling anchor


Posted June 1, 2016 by sinorockbolt

Self drilling anchor, an advanced anchoring system, is a kind of bolt integrated with the functions of drilling, grouting and anchoring.

 
There has been a significant increase in the infrastructure development in hilly areas such as construction of hydro power projects, highways and construction. The increased economic activity has resulted in an increase in landslides in the hilly areas resulting in loss of infrastructure and lives. This has led to widespread concern on risks associated with disturbance of hills and mountain slopes.
Therefore, Slope protection & stabilization has become an essential activity in any infrastructure project that has risks of landslides & slope failures due to construction or weather disturbances.
Slope Stabilization is a process that involves first spraying of wet cement concrete (100 mm thick) on the slope to be stabilized. This process is called shotcrete. Post this a wire mesh fabric is applied on the first layer with small nails and second layer shotcrete (100 mm) is applied. Further the soil is nailed by drilling the slope and inserting grout tubes and then sealing them with anchor nails.
Through our extensive technical & operational experiences we have gained wide respect as a quality job specialist engineering company providing slope stabilization & protection.

Self drilling anchor, an advanced anchoring system, is a kind of bolt integrated with the functions of drilling, grouting and anchoring. It can ensure anchoring for complex ground conditions. Nowadays self drilling anchor system has been and will be increasingly used for Slope Stabilizations.
Self drilling anchor bolts are hollow structure, so it can be used as drill bar and mortar conveying pipe. Slurry jets from bit through anchor bolt, permeates the surrounding of anchor bolt under pressure and then fills the cracks of broken rocks. It can consolidate surrounding rocks and strengthen anchoring effect.
