The self drilling anchoring system is a convenient and quick anchoring method based on the problems encountered in the construction and improving the original anchoring methods. It can complete the anchoring work in a one-stop way. In the early stage of construction, we must anchor the surrounding rock and soil layers to prevent collapse during the later construction period. According to the engineering conditions, the technicians designed the most reasonable quantity of bolt and construction position, then supported it. The traditional anchorage method requires grouting into the borehole after drilling. Under complex geological conditions, the borehole can easily collapse and the anchorage cannot be achieved. The self drilling anchor system integrates drilling, grouting and anchoring. The drill can easily penetrate all types of rock mass and the bolt itself is a drill pipe. In the drilling process, the hollow rod body is grouted, and the grouting material directly flows into the drill hole through the drill hole to anchor the surrounding rock mass. The one-stop anchor system not only solves the shortcomings of traditional anchorage methods, but also saves engineering time, and is widely used in complex geology where two-step construction is not possible.
