Self drilingl grouted anchor bolt is applicable to engineerings of railway, highway, tunnel, mine, water control project, slope, dam, bridge group, banks of river, ocean, sea, foundations of high buildings and building reinforcement projects etc. While it is more suitable to governance of the sinking foundation, hole collapse, crack, landslide etc. geological hazards. Contemporarily, construction within narrow environment is quite convenient, solving the difficult technical problem about unfavorable geological conditions, which no other material can serve as the substitution.
