Installation of self drilling and Swellex soil anchor
The self drilling soil anchor is designed for optimized installation, tailored to the project's needs. By drilling a hole in collapsing soil or loose rock, with a sacrifi cial drill bit and a hollow rod, and after the drilling operation injecting grout into the hollow rod and surrounding cavity, makes it a top productivity solution.
The Swellex soil anchor is a folded steel tube, which is inserted into a pre-drilled hole in the rock. Water is blasted into the tube at high pressure, blowing out the fold and expanding the tube into the exact shape of the hole, adapting to every irregularity. Bolt installation takes less than 30 seconds, and provides full and immediate support along the entire hole length, in ground conditions ranging from the hardest rock to clay even non-cohesive material.
