Self-drilling hollow anchor bolts and accessories

Transcription

1 Self-drilling hollow anchor bolts and accessories Application During the constructions of underground works, it is very common to encounter soft rock, fractured zone and large deformation due to high ground stress. In the case of serious collapsing, extra-long anchor is needed instead of ordinary one. Maxdrill self-drilling anchor embodies drilling, grouting and anchoring as a whole. Widely used as an efficient anchoring means, in tunnel pre-support, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sink age. It s irreplaceable in narrow construction environment. 1
