Hollow anchor bar has following advantages:

1. High efficiency: Self-drilling hollow anchor bar  combines drilling, grouting and anchoring together, several processes can be done at the same time, which is time-saving and high-efficient.

2. Suitable for stratum which difficult to drill hole: When encountering loose and broken surrounding rocks, it is difficult to drill hole and easy to collapse; while self drilling rock bolt can overcome this situation. After drilling hole, anchor bar still stays in the hole, which ignores collapse, saves time and reduce construction difficulties.

3. High adaptability: There is whole thread on the surface of self drilling hollow anchor bar, it can be cut at any position. So it is suitable for different construction conditions.

4. High anchoring force: The thread of self drilling hollow anchor bar divides into R-thread and T-thread. They can both connect with coupling tightly and have good bonding effect with grouting slurry.

5. Good anchoring effect: When grouting, slurry is from the bottom to orifice, the effect is full and dense, grouting quality is good.

6. Simple to construct: Compared with common rock bolt, self drilling hollow anchor bar has decreased the processes of pulling out of hole, installing anchor bar and inserting grouting pipes, which is quick and simple.

For home repair needs due to storm surge caused by a natural disaster, the first step is to contact a Certified Sinorock.
