Rock anchor bolts are used in the mining industry and for tunnel construction

Rock anchor bolts are used in the mining industry and for tunnel construction to prevent or slow mountain movements of the bedrock or to secure major chipping of bedrock and hence allow a risk-free operation. Two principles have been disclosed for this purpose, which are in part also combined. With mechanical systems, the anchor is braced friction-tight, whereby mechanical rock or stone anchor bolts generally also comprise an expansion bolt. For chemical rock anchor bolts, anchor tubes are bonded with the subsoil or the bedrock using curing mortar or synthetic resin used as fixation substance. In doing so, the rock anchor bolts are installed in the bedrock with or without pre-stress. In contrast to tunnel construction, rock anchor bolts used in the mining industry, e.g. for underground coal mining, are only used to temporarily secure the rock, because the temporarily secured rock is generally extracted during a subsequent work step and hence the rock anchor bolts are removed from the rock again.
Currently,self drilling rock anchor bolt support technology has been applied to many projects, but the project has a certain complexity and uncertainty, every concrete construction of geotechnical engineering, has its own particularity.
Through the introduction of new technology,Sinorock excellent rock anchor bolt system provides the ultimate solution for securing unstable embankments and rocky slopes.The Sinorock excellent rock anchor bolt system ensures a fast and efficient method of application with a superior strength and rigidity that we believe is the best available.
