[0003] The traditional grouting method is often completed by one-time grouting, and the grouting quality can only be controlled by the quality of mortar and grouting speed, which cannot be effectively controlled. After the solidification of mortar, air holes and air holes caused by uneven mixing and not discharging internal air bubbles, insufficient pouring and air holes, insufficient penetration and bonding of mortar and surrounding rock, resulting in insufficient bearing pressure of grouting body and decreased friction between rock and rock, which cannot provide stable bearing capacity for steel strand anchor rod. SUMMARY

[0004] In order to solve the technical problem of poor steel strand grouting quality, the present application vibrates the mortar in the protection sleeve by one-time grouting, fully mixes the mortar, makes the air bubbles in the mortar vibrate and out, fully grouts the mortar, improves the grouting quality, fills the air holes in the mortar produced in the first grouting, enhances the penetration effect and bonding force of the mortar in the rock, improves the grouting quality again, improves the grouting effect, improves the bearing pressure and friction between the solidified mortar and the surrounding rock, and provides stable bearing capacity for the steel strand anchor rod.
