Sinorock’s ground anchor system as an efficient stabilization tool
Sinorock Self Drilling Ground Anchor provides an effective permanent anchor that can be readily installed into loose or collapsing ground without the need for a casing. Rotary percussive drilling, combined with simultaneous grouting, ensures that the grout penetrates the surrounding ground to provide an increased level of bond.
All Sinorock Self Drilling Ground Anchors should incorporate a fixed length (bonded in the stable zone) and a free length (debonded with a sleeve, in the wedge zone) to enable the anchor to be prestressed. The prestress provides an active restraint, enabling the anchor to resist service loadings without additional elongation.
Sinorock Self Drilling Ground Anchor Systems (irrespective of threadform) are very suitable as permanent anchors. The ground anchor length is flexible, it can be lengthened. It adapts to several projects, such as railway, tunnel, hydro-junction, slope, dam, bridge base, high-rise building, construction reinforcement and so on.
Sinorock’s ground anchor system has been largely used as stabilization of tunnel portals, fore-poling, face stabilization, spilling, root piling and radial systematic anchoring.
Its construction features are as follows:
1. Have tow functions of the bolt and grouting pipe. It is a grouting pipe when grouting, then becomes an anchor bolt after grouting without pulling out.
2. The hollow design allows the bolt to achieve a function of grouting tube, which can avoid the loss of mortar when using traditional ground anchor
3. Full grouting and pressure grouting. It can improve the project quality.
4. Sinorock’s ground anchor system can be perfectly put in the middle of rock by using the various parts. And its body is wrapped by mortar, which can avoid the danger of corrosion and achieve long-term support.
5. Easy installation. It is easy to install plate and nut without on-site processing thread.
