One, Wooden Anchors. There are two types of wooden anchors used in our country: ordinary wooden anchors and compressed wooden anchors.
Reinforcement or steel wire rope mortar anchors. Using cement mortar as the bonding agent between the anchor and the surrounding rock.
Three: Wedge-shaped metal anchor rods. This type of anchor rod was once one of the more widely used anchor rod forms. Due to its simple processing, easy installation, and certain anchoring force, this anchor rod is still in use within a certain range.
Four: Threaded Anchor Rods. These are full-length friction anchoring rods. They feature simple installation, reliable anchoring, high initial anchoring force, and the anchoring force increases over time with the movement of the surrounding rock.
Resin Anchor Rods: Utilizing resin as the bonding agent for anchor rods is more costly.
Six, Quick-hardening expansive cement anchor rods. Made from ordinary silicate cement or slag silicate cement with the addition of admixtures, they feature rapid setting and early strength, water reduction, and expansion characteristics.
Seven, Double Quick Cement Anchor Rods. These are made by mixing finished early-strength cement with double quick cement in a certain proportion. They feature rapid hardening and early setting, as well as early strength.
