Sinorock self drilling rock bolt comes with couplings, different types of bits, centralizers, nuts and anchor plates, and also several accessories for injection.Our range of self drilling bolt has the following threads : R25, R32, R38, R51, T30,T40,T52 and T103, etc.,with several inside diameters.R thread anchor bar or called rock bolt, soil nail, which is a kind of threaded hollow bar, bar surface with an rope thread according to ISO 10208 & 1720. It was firstly invented by MAI on 1960S to solve the low construction speed on complicated underground works, nowadays; it is very popular all around the world.T thread anchor bar surface with a trapezoidal thread, this design of connection is much stronger and reliable when compared with rope thread, we supply full sizes from T30 to T103.
The self drilling anchor supporting structure must have a good ductility,in other words,no doubt the destruction is inevitable occurs if the self drilling anchor supporting system that has no the pressure and yield properties.The self drilling anchor can be lengthened as required so it is well applicable to railway,tunneling,mining,hyrdroelectric station,slope stabilization,dam,brige foundation,river,breakwater,high-rise construction frastructures and othe projects .And it is more suitable for settlement,collapsed hole,fissures,landslide and so on.Meanwhile,it’s also very convenient for operating in narrow space or with limited headrooms and the quality of anchorage material is incomparable.
Today, Sinorock performs geotechnical installations that conform exactly to the plans. We provide construction services that are compliant and accurate, without deviations. And we still provide customized, design-built geotechnical solutions.Please feel free to contact us!
