The Lightspot of Self Drilling Anchor

Metis® self drilling anchor is widely used in deep foundation supporting and retaining, slope reinforcement, landslide remediation, pools’anti-floating, anchored retaining wall and structures’anti-overturning etc. It is mainly used to support the rock in fault fracture zone. For example, the application in Xiluodu hydro-power station, according to the upper overburden layer excavation of left and right bank outlet shaft, by proving and practicing the self drilling anchor under different geological conditions, self drilling anchor technology is integrated into soil reinforcement construction under complex geological conditions. This technology changes the traditional soil reinforcement technology.

Because the prevalent types of soft surrounding rock, complicated geological conditions and high ground stress in underground engineer, it brings great difficulties to rock anchor construction, especially in the situation of hole collapse. Self drilling anchor, as a new-type anchor, has the functions of drilling, installation, grouting and anchoring simultaneously. It can improve the surrounding rock to achieve better supporting effect than traditional anchor.
