Care este principiul procesului de șuruburi de rocă goală combinată?

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 will penetrate into the fissure of surrounding rock under pressure, and then form a whole, so that the surrounding rock body within a certain thickness can form a "load-bearing ring", and under the action of the strong pull-out force of the anchor, the surrounding rock has sufficient load-bearing capacity, which increases the stability of the surrounding rock.
