Jaký je princip procesu kombinovaného dutého rockového šroubu?

Anchor components: anchor head, hollow anchor rod body, slurry plugs, pads, nuts and plugs (combined hollow anchor also contains: exhaust channel, connecting section, solid anchor rod body), the anchor diameter of 25mm, the surface with threads, there is a hole in the middle of the anchor, the anchor rod is inserted into the anchor holes that have been chiseled by the rock driller, and then through the hollow hole slurry injection solidification, some of the slurry will be infiltrated into the fissures of the surrounding rock under pressure, the solidification of the surrounding rock body of a certain thickness to form a "load-bearing ring", under the action of the strong resistance to pull-out, increasing the surrounding rock has full load-bearing capacity, increasing the surrounding rock has a strong resistance to pull-out. After consolidation, the slurry pronikne do trhliny okolní horniny pod tlakem a poté vytvoří celek, aby okolní skalní tělo v určité tloušťce mohlo tvořit „nosnoucí prsten“ a pod působením silné vysuzovací síly kotvy má okolní skálu dostatečnou kapacitu zatížení, což zvyšuje stabilitu okolní skály .
