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 can put drilling, anchoring and grouting together, it had great help for increasing efficiency. Self drilling rock 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 rock 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 rock 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. Sinorock will seize opportunity, research and develop new technology, produce more practical self drilling anchors and then protect construction engineering projects. Self drilling rock bolt is a very good choice for tunneling engineering. Combining drilling, grouting and anchoring together, it’s reliable, efficient and convenient. Sinorock can produce R25, R26, R32, R38, R51, R63, T30, T40, T52, T73, T76, 103, T111, T127 and T130 sizes and customized products to meet all the demands of self drilling rock bolts.
