Self drilling bolt is the most widely used supporting method in the world recent years

is the most widely used supporting method in the world recent years. It overcomes the disadvantages of common anchor
bolts, combines drilling, grouting and anchoring together, time-saving, labor-saving and high-efficiency. Self drilling bolt is mostly
applied in complicated geological conditions, it can make projects stabler and have a longer life.
So far, China has went out, investing and cooperating with many projects. Devices, technology and construction quality have got affirmation
and reputation in the world. Among these methods, the best supporting one is adopting self drilling bolt, which is high-efficient, convenient
and easy to operate. With it, projects are stronger and more stable, quality has got guaranteed.
The anchoring technology of self drilling bolt can raise surrounding rocks’ intensity and stability. It has advantages of easy to operate,
low cost, safety and promptness, etc, which has brought attention in the field of mining industry and geotechnical engineering. Self drilling
bolt is a kind of supporting structure of high-rise buildings, its integrity and impermeability has little effect on surrounding environment
and it has strong adaptability for stratum conditions. So far, self drilling bolt has been widely used in China.
The quality of self drilling bolt has two main indexes: anchoring force and anchoring status.
Anchoring force is a binding force between self drilling bolt and surrounding rocks. The anchoring force is bigger, the product is more
reliable and the effect is better. Drawing force is the best testing method.
Anchoring status refers to the length of anchorage section, length of free section, compactness and construction deficiency, etc. Because of
the influence of materials, construction and geological conditions, there exist many deficiencies during the construction and usage of self drilling bolt.
To avoid these deficiencies, engineering accident and economic loss, the anchoring quality of self drilling bolt is quite important.
