Self drilling rock bolt support has many advantages, such as instant bearing, large pretension force, good support effect, low labor strength and low cost, etc.Nowadays, self drilling rock bolt technology has become an effective way to realize high efficiency and production.
Self drilling rock anchor system, one of efficient supporting methods, has played important role in reinforcing and supporting engineering. As for underground engineering, such as metro station and foundation pit supporting, self drilling anchor system can bond itself to soil and ground, which can enhance integrity and cohesiveness, avoid deformation and collapse.
Self drilling anchor of Sinorock is a kind of prestressed anchor, which combines drilling, grouting and anchoring together.Self drilling anchor bolt in slope treatment were able to achieve the ideal effect in improving the surrounding rock, which nicely solves the problem of drilling difficult in anchoring construction, it is an economic, safe and highly effective geotechnical reinforcement technology and now is widely used in tunneling, mining and slope works.The self drilling anchor bolt system are used widely to improve the stability and load bearing characteristics of a rock mass.
Often they are used to stabilize relatively small blocks of rocks in cuttings, slopes and underground excavations such as tunnels, caverns and mines. They can be used on their own or in conjunction with other support systems such as ground anchorages.
