To fasten the dam foundation, cement grouting and drainage system were adapted. Because of the compact time, several working procedures should be done at the same time. Self drilling anchor bolt can put drilling, anchoring and grouting together, it had great help for increasing efficiency.

Self drilling anchor bar is hollow structure, so it can be used as drill bar and mortar conveying pipe. Slurry jets from bit through anchor bar, permeates the surrounding of anchor bar under pressure and then fills the cracks of broken rocks. It can consolidate surrounding rocks and strengthen anchoring effect.


Self drilling anchor , as an economic and superior technical method, has been applied in different engineering fields. It can not only applied in main coal-producing countries, but also in the field of metallurgy, water conservancy and hydro-power, railway, highway, tunnel and civil construction, etc. 

With the coming of 21st century, underground engineering projects have became more and more. It can be predicted that ground anchoring technology will be researched and popularized further.

Our company will seize opportunity, research and develop new technology, produce more practical self drilling anchors and then protect construction engineering projects.
