The support effect of self drilling anchor bolt has constantly strengthened

For a long time, the protection technology of side slope in China is a weak link in road construction. Before the mid-1980s, China mainly has low-grade road, traffic is less, invest is less and the depth of digging is shallow, so it is unnecessary to focus on the protection technology of side slope. After the 1990s, construction of highway has entered a top-speed stage. Without systematic research, mature experience and technology support, it has brought hidden danger, great loss and bad social effect, sometimes it even broke the traffic and roadbed collapsed. This phenomenon has connected not only with the quality of materials, but also with the side slope protection system.
Recent years, the research of side slope protection system and reinforce technology in highway has been focused by most people. The support effect of self drilling anchor bolt has constantly strengthened and played a more and more important role.
The technological characteristics of self drilling anchor decided its use on slope foundation.

1. Self drilling anchor adopts seamless steel tube, thread covers its whole body, which realizes the function of drilling, grouting and anchoring. It is not only a drill bar, but also a grouting tube and supporting body of soil pressure. It can be cut into random length and linked together according to your demand. Self drilling anchor simplifies construction procedure, accelerates construction speed, saves about 25% workload and relieves operators’ labor strength.
2. Self drilling anchor equips with special and all kinds of drill bits to adapt for various stratum.
3. High-strength coupling adopts mechanical cutting technology, so self drilling anchor has character of drill and lengthen together, which makes long self drilling anchor construct in small space.
4. Because adopting anchor bar as drill stem, it doesn’t need casing pipe to protect wall and preliminary grouting.
5. It’s convenient and dense for grouting. The anchoring strength is increased.
6. Surrounding environment has little influence on self drilling anchor, so it can keep continuous and balanced construction. The degree of mechanization is high, noise is low and dust is little.

7. Under the same load, self drilling anchor has bigger resistance than solid one.
