The advantages of self drilling anchor system in terms of applicable formations

With the gradual increase of railways, highways, tunnels, excavation and other anchor projects, the use of self drilling anchor system worldwide also showed a rising trend, Self drilling anchor system can be integrated with the functions of drilling, grouting and anchoring, with the characteristics of quick and easy installation, suitable for a variety of geological conditions of rock, and can be applied to a variety of engineering fields of rock-soil engineering. So compared with the traditional anchoring systems, what are the advantages of Self drilling anchor system in terms of applicable formations?

1.Wide range of application: Self drilling anchor system applies not only to the applicable formations of the retaining wall and soil nailing wall, but also can be applied to prestressed anchor cable applicable formation.

1) In the retaining wall class structure, it can effectively be applied to anchor retaining wall, soil nail wall and prestressed Piles.

2) In the engineering of slope stability management classes, for the problem of rock bedding, mountain excavation of anchor can be used to impose less stress.

3) For city construction, the question of excavation and supporting of deep foundation pit, using the self drilling anchor system can avoid space narrow, and difficult construction problems.

2. Apply special strata:

1)Self drilling anchor system used in weathered rock, gravel, clay, sand and pebble soil, such as hole geological environment, without casing, simplifying the construction program, saving at least 25% per cent of the workload, which greatly shortens the duration.

2) For loose strata and space more, with open fracture of rock stratum, to compensate the geotechnical defects by high pressure grouting, expanding the anchor solid diameter.

In short, self drilling anchor system can effectively replace the traditional anchor, is a reliable geotechnical anchoring new technology and has broad application prospects.
