Self Drilling Rock Bolt is a product in which drill pipe and anchor are combined. In the backfill area, weathered rocks, crushed rock layers, sand, clay, pebble layers, etc. These areas do not need casing protection, and can form anchor holes to ensure the effect of anchoring and grouting. Self Drilling Rock Bolts are easy to operate, fast and time-saving, which can save 25% of the workload and greatly reduce the engineering costs.

The self drilling rock bolt has the following characteristics:

1. It has continuous standard wavy threads, which can be used as a drill pipe to cooperate with a drill to complete drilling into anchor holes;

2. The anchor body of the drill rod does not need to be pulled out, and the hollow can be used as a grouting channel for grouting from the inside to the outside;

3. The high-efficiency stop plug allows the grouting to maintain a strong grouting pressure, fully fill the gap, fix the broken rock mass, and the high-strength pad and nut can evenly transmit the stress of the deep surrounding rock to the surrounding wall rock. In order to achieve the purpose of supporting each other with surrounding rock and anchor rod;

4. Due to the trinity function of the Self Drilling Rock Bolt, it can form anchor holes and ensure anchoring and grouting effects without special methods such as casing wall protection and pre-grouting during construction under various surrounding rock conditions;

5. The self-propelled anchor uses good thick-walled seamless steel pipe material, fast surface thread forming process and well-crafted accessories to truly achieve the unity of Self Drilling Rock Bolts, grouting, and anchoring functions;

6. There is a strong penetrating drill bit in front of the Self Drilling Rock Bolts, which can easily penetrate various types of rocks under the action of ordinary rock drilling machinery.
