Most of these soil sites are made of silt, silty clay or sandy soil. Due to their fragile soil buildings, they are in an open-air environment and have been subjected to various natural camps such as wind erosion, rain erosion, freezing and thawing, and earthquakes for a long time. Influenced by force and human activities, unstable blocks directly cut by fissures or fissures are commonly developed in soil sites. Therefore, the research on the ideal reinforcement method of unstable blocks in earthen sites is more and more urgent. Anchoring technology has been widely used in the field of stability control of soil sites because of its weak disturbance, strong concealment and high anchoring force.

Long-term engineering practice and anchoring test studies have found that providing reliable grouting pressure and effective vibration for the anchoring of soil sites is the key to ensuring the quality of the anchoring project. Therefore, a special equipment for anchoring and grouting of soil sites was developed It is necessary to transport to the surrounding of the rod body, and effectively vibrate the slurry to remove the air inside the slurry, ensure the effective bonding between the bolt, the slurry and the site body, and ensure the quality of the anchoring and grouting construction of the soil site.
