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.
And the self drilling anchor bolt of Sinorock is widely used in projects of tunnel support, radial support, slope reinforcement, reinforcement and subgrade disease control engineering as an effective anchoring mean. In recent years, in China, self drilling anchor also has extensive use in Chinese rail systems, such as second line of Baoji-Chengdu Railway, Bao-Zhong Line, Nanning-Kunming Railway Line, Suo
Huang line and several tunnels, embankment, slope in highway system. The wide application of self drilling anchor bolt has not only reaped significant economic benefits, but also resulted in good social and ecological benefits.
