Self-drilling hollow grouting anchor bolt is an efficient support product integrating three major functions of drilling, grouting and anchoring, specially designed for geotechnical projects such as tunnels, mines, slopes and foundation pits. Adopting a hollow threaded structure, the interior of the bolt body serves as a grouting channel to realize integrated construction of drilling while grouting, which effectively solves engineering problems including difficult hole forming and insufficient grouting in weak and broken strata.
