The self drilling rock bolt in Sinorock can be well connected with drilling machine, rock bolting jumbo, grouting machine, etc.The hollow anchor bar is a drill pipe which is convenient and time-saving, it can transmit structural load to foundation and then limit the deformation of buildings. Because of it with standard full thread, it can be cut and lengthened according to clients’ specific demands. The anchor bar can be connected by couplings and it is suitable in narrow work spaces. Clients can choose different drill bits for different ground conditions. Based on the different specifications of anchor bar, the technical parameters is different, and the ultimate load, yield load is different, too. Owing to the conventional standards of self drilling anchor bar: R-thread (25/32/38/51mm) and T-thread (30/40/52/73/76/103/111/127mm), it provides higher bonding stress than smooth steel pipe.
