The Current Situation and Development of Self Drilling Anchor at Home and Abr

Ground anchoring technology is an important branch in the field of modern ground engineering. It is also called anchor bolt supporting technology in China. Self drilling anchor is the typical one.
Self drilling anchor is a positive support with simple structure. It can keep surrounding rocks’ integrity and stability in great extent, it can control deformation, displacement and cracks effectively, and it can develop the supporting effect of surrounding rocks. It has the features of transport-convenience, high-efficiency, low-cost, good-supporting effect and low-noise, etc.
Since 1872 the first application of self drilling anchor applied in slope reinforcement in North Wales and 1912 the first ground anchoring technology applied in coal mine underground roadway in Germany, it has over 100 years’ history for ground anchoring technology at moment. 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.
