To keep stable of slope, there are two ways: one is to cut slopes for reaching stable; the other one is to install retaining structures. While the first way is not economical or practical, so self drilling rock bolt is a quite convenient and safe method for reinforcement.
Sinorock Self Drilling rock bolts - These are fully threaded, hollow core, cold rolled anchors with continuous outside thread suitable for attaching bits and couplings, which also forms a superb mortar connection. They are supplied with couplings, anchor plates and nuts, and five bit designs are available.
Sinorock Self Drilling Anchors are used for temporary and permanent stabilization in NATM; retaining walls in confined spaces; and slope stabilization for roads, railways, and tunnel portals.
The ability of Sinorock self-drilling rock anchors to provide effective solutions without the need for additional casing operations enables designers, developers and contractors to construct foundations quickly and economically.

The excellent production rates achievable and ability to install the anchors in confined spaces makes the solution ideal for a wide variety of foundations projects, where alternative methods would prove uneconomic or unfeasible.
Sinorock self-drilling injection anchors provide one of the most cost effective means of maximising work and development space in temporary works situations.
