Self drilling bolt, because of its superior performance and got rapid development, and is widely used in many fields of civil engineering.It can join many different kinds of structure.As an economic and effective reinforcement measure, It has been extensively used in the foundation pit wall,tunnel, retaining wall, dam reinforcement and slope reinforcement engineering, can save a lot of masonry materialsand funds.
Self drilling anchor using pumpable cement grout, to anchor the bolts, have been used successfully in the tunnelling and civil engineering industries for many years. Pumpable cement grout offers the considerable advantage that the self drilling rock bolt can be fully encapsulated including filling of cracks and joints in the borehole. However, cement grout cannot provide the immediate support required for the coal industry. This paper descrembed a new self drilling anchor system which uses pumpable resin to anchor the self drilling anchor in a borehole to not only provide all the advantages of a pumpable anchoring system, but also to provide immediate roof and rib support as required in the coal industry.
Recent development includes the self drilling anchor bolt. Deeply believe that the measure of our worth is in the development and innovation of new products, and we are pursuing the “China Sinorock direction of technology and quality” all the way.
Headquarter of Sinorock is located in Henan, China and now we have two manufacturing bases as our strong support. One is located in changzhou about 450,000 square meters, and the other is in luoyang city, about 600,000 square meters.And we have enough space for storing anchor bolts to support your projects.
