The main characteristic of the self drilling ground anchor system is that the disposable drill bit is combined with the hollow anchor to realize the integration of drilling, grouting and anchoring. It reduces the drilling failure rate, improves the construction efficiency, and saves more raw materials, therefore it is used in many anchorage projects. The construction of self drilling anchor system is simple and requires only a small robotic arm to complete the installation. It is very suitable for remote areas and traffic road underdeveloped area where large machinery is difficult to reach. The hollow bolt adopts thread design, and different types of drill bits can be installed under different geological conditions to achieve the best drilling effect. Therefore, the self drilling anchor bolt has strong adaptability and wide application. Self drilling ground anchor are used to solve the problem of engineering anchorage support. It penetrates deep into the interior of the rock formation and withstands large tensions and pressures. Therefore, it must have great tensile resistance and pressure resistance in order to be able to provide strong support for engineering.
