Sinorock self drilling anchor system facilitates your work to a great extent

The effect of self drilling hollow grouting anchor anchorage effect of shallow landslide is quite obvious, especially through the grouting technology of rock stone, making the shallow broken rock into a whole, and then use the long and short anchor bolt staggered arrangement, which effectively improve the overall slope stability, the ordinary mortar anchor bolt is unable to play this effect.
It can be used as a reference for the reinforcement of shallow landslide in other similar projects. Self drilling hollow grouting anchor for broken rock construction, with the advantages of progress quickly, reduce the construction difficulty and improve the efficiency of the engineering, but the cost of raw materials compared with ordinary cement mortar anchor bolt is high, such as to further reduce the cost of materials, application in hydropower market will be more widely.
Sinorock's Self drilling Anchor consists of continuous thread anchor bar, coupler, drill bit, nut and plate. It can make drilling, grouting and anchoring simultaneously without using casing pipe and drill rod.It's capable of being used in weak surrounding rock, crumbly strata and loose soil.
Our self drilling anchor bolt is a fully threaded steel bar which can be drilled and grouted into loose or collapsing soils without a casing. The bar features a hollow center for simultaneous drilling and grouting and a rope thread for connection to standard drill tooling. SDA forms a standard rope thread profile (R25 - R51, T76 has a trapezoidal thread). SDA can be installed into a variety of different soils and ground conditions ranging from sand and gravel to inconsistent fill, boulders, rubble and weathered rock, as well as through footings and base slabs.
The Sinorock self drilling anchor system facilitates your work to a great extent, as it is capable of performing drilling, anchoring and injecting procedures all at once. The self drilling anchor system has a hollow interior, a threaded exterior and a drill bit that is used for drilling. The hollow interior of the self drilling anchor system allows air and water freely pass through the drilling process, flushing the particles. It also facilitates immediate injection following completion of the drilling process.
