Hollow anchors are also called prestressed hollow grouting anchors , hollow composite anchors, etc. Hollow grouting anchor rod is a kind of hollow anchor rod. It is generally used for relatively stable and complete rock formations, resin, engineering glue, quick-setting cement and other anchoring agents to inject from the center of the anchor rod. The anchoring quality is better than that of general anchor rods. . Since the advent of entrance into the hollow bolt grouting, under loose ground conditions, may be used in the formation of hollow bolt grouting . Hollow grouting anchors are easy to install, ensuring timely application of prestress. Active stretching, up to 50KN pre-stress and appropriate over-stretching; using conventional tools, one person can complete the pulling work. High-pressure grouting can be achieved through the hollow rod body to improve surrounding rock; comprehensive control is carried out from production to installation to ensure quality.

Attention should be paid to the use of hollow grouting anchor rods . The grouting workers must have protective tools; check the equipment and wiring carefully. Avoid leakage damage. The grouting worker and the grouting pump driver must coordinate well. After grouting is completed, the valve must be closed before attention to the grouting machine; the grouting port is not allowed to face people.

5 obvious advantages of hollow grouting bolts : 5 obvious advantages:

1. The hollow grouting anchor saves additional grouting pipes and exhaust pipes. The drilling, grouting and anchoring are integrated, and the construction method is simple, safe and low in labor costs.

2. Hollow grouting anchor rods have fixed hollow rods and grout plugs. Slowly grouting, venting, boosting, connecting the rock mass from the inside, injecting pressure grout into the cracks, the condensed rock improves the strength of the surrounding rock.

3. The bending moment and shear force of hollow grouting bolts are greater, and the grout can include full-length pavement bolts, and the adhesion between the outside and surrounding rock is greater.

4. Hollow grouting anchor rod and shotcrete combination system support, rigidity and softness and excessive coupling can make full use of anchor spray support, thereby greatly reducing project costs.
