Self drilling anchor has been around for at least 40 years.It is developed for tunneling applications in weak or collapsing ground.Until today it is still used for the NEW Austrian Tunneling Method (NATM).However,Unlike the solid reinforcing bar, criteria for self-drilling hollow bars were not perfect in the past.Manufacturers had only concerned about loading capacity and surface profile.
Sinorock self drilling anchor system effectively improve the stability of underground rock masses. The increased load bearing capacity of the rock conditions enables an early construction start, thus providing both technical and economic advantages.Please choose Sinorock as your partners of self drilling rock anchor bolt.
The Sinorock self drilling anchor is hollow design,and suits well to various kinds of ground conditions containing loose rocks,broken rocks,fracture zones,unconsolidable layers,sandy gravel and other complicated geological conditions. By the coverage of full length grout,the self drilling anchor bar provides a strong strength between rod body and surrounding rocks,as a result allowing for direct monitoring of the rock mass movement,which gives a full guarantee to the safety and peace of mind to the workers in the constructions.
The self drilling anchor of Sinorock has a widely application, It is usually used to broken rock,loose soil and conditions which difficult to drill holes,such as fracture zones,decayed rock,gravel ect.Especially in the sand gravel stratum, using the traditional method of anchoring, the low probability of pore formation makes it difficult to grout and anchor lately and also increases construction costs.
Whether used in cohesive or non-cohesive ground, the Sinorock self drilling anchor bolt can be grouted and then stressed and locked off with a hexagonal nut and plate. Advantages are: similar installation for all ground conditions; no casing required; fast drilling and anchoring in a single operation; choice of bits and anchor loads; and hollow core for high-volume flushing and grouting.
The anchor bolt ,as descrembed here, is a standard Permanent Ground Anchor . Both the bond between the steel strands and the casing and the bond between the casing and the surrounding ground are provided by the backfill grout as descrembed. The reliability of the system hinges on the efficiency of the shrink compensating grout additives, which are expected to avoid the formation of a gap at the two interfaces upon completion of grout curing.

According to user requirements We summarize the self drilling bolt Torque Requirements.Self drilling bolts are designed to stretch a little when being tightened. It is this elongation, or tension, that clamps a bolt-joint together.
However, the tension of a bolt is difficult to measure so manufacturers and standards organizations often resort to specifying the torque, twisting force required to spin the nut, when specifying industry standards.
As the expert in self drilling anchor system field,Sinorock is outstanding.Here We will stated how to install self drilling bolt in Concrete.
Self drilling bolts are an essential part of concrete construction. These are bolts, placed in the concrete with the threaded side up. They allow you to secure wall forms or other portions of the construction onto the concrete foundation slab. It’s important when placing rock bolts to place them carefully and accurately, since moving them later will be extremely difficult and will hold up your construction project significantly.
