Hollow grouting anchor rock bolt is an important support material in geotechnical engineering, which has the following main functions:

1. Waterproof effect: Through grouting agent injection, fill the gap between the drilling hole and the soil layer, improve the density of the soil layer, so as to prevent water from entering the underground project through the soil layer.

2. Soil reinforcement: Through the injection of grouting agent, the internal friction resistance of the soil layer is increased to prevent the soil layer from sliding and deformation due to gravity and earthquake.

3. Strengthening the geological layer: It can have a strengthening effect in the geological layer to avoid deformation and collapse of the geological layer.

4. Enhance the stability and bearing capacity of rock mass: prevent the occurrence of geological disasters such as rock slides and collapses.

5. Rapid formation of supporting force: pressure grouting of the anchor rod through the hollow rod body, consolidation of broken rock mass, partition of groundwater, and anti-corrosion function.

In summary, hollow grouting bolt plays an important role in geotechnical engineering, which can effectively enhance the stability and bearing capacity of rock mass, prevent the occurrence of geological disasters, and have the functions of quickly forming supporting force, isolating groundwater and anti-corrosion.
