conducted.

 
2. Through the hollow rod to achieve high-pressure grouting, rock
reinforcement to improve project quality
 
3. Avoid the mortar loss when the traditional grouting tube pulled out.
 
4. Center is good, mortar can wrap the bolt body together, so that it can avoid corrosion to achieve a long-term supporting purpose.
