Self drilling anchor system has solved the problems of hole shrinkage and hole collapse caused by drilling in sandy gravel layer, which played a good anchoring effect, achieved a purpose of supporting sandy gravel layer in the slope. It can be extensively applied in other loose rocks and soils.

Self drilling anchor system is a new type of anchoring technology, which is used in foundation pit, highway, tunnel, slope support and other engineering fields. Self drilling anchor system integrates drilling, grouting, installing and anchoring processes in one operation. It has the advantages of simple process, high construction efficiency, good economic benefit, etc. This system will overcome the problems of narrow aperture, hole collapse and hole forming during drilling hole in loose broken rock and soil and sandy gravel layer and have a good anchoring effect.

Our self drilling rock bolt system has following advantages: 1,Our each piece of rock bolt is manufactured by premium steel and most advanced technology, which ensures our quality can be international standard or even better. 2,Self drilling rock botling system eliminates the requirement of a cased borehole, so drilling, grouting and anchoring can be finished simultaneously. 3,Self drilling rock bolts can be used only for temporary support, but also for permanent support in many applications, like tunneling supporting, micro piling, soil nailing, etc.
