Sinorock is dedicated to manufacture rock reinforce - ment products, such as self drilling rock bolt, FRP rock bolt, friction bolt, etc.
Sinorock is a leading manufacturer of self drilling rock bolt system for the the mining, tunneling and civil construction industries. As an efficient anchoring method, our self drilling rock bolt is used in complicated, loose and broken geological condition.
The anchor bar features a hollow bore for flushing, or simultaneous drilling and grouting, and has a left-hand/right-hand thread for connection to standard drill tooling.
Prime advantage of the self drilling rock bolt
1, Easy and similar operation principle for different rock mass and soil conditions
2, Drilling, anchoring and grouting can be performed in one single operation
3, No pre-drilling of a borehole by using a casing tube and extension rods with subsequent anchor installation necessary
4, Minor space requirement for the accomplishment of anchoring
5, Optimized machinery and manpower requirements
6, Basic dimensioning of the required anchoring forces by choosing the appropriate anchor type
7, Optimum bonding of the profiled anchor rod and the grout
8, Adjustment of the drill bit design and diameter to different rock mass and ground conditions
9, Simple anti-corrosion method available
10,Appropriate for temporary or permanent applications
