The self drilling rock bolt can be used to put drilling, grouting and anchoring together, it is simple to install and operate, and it is
safe, reliable and time saving.It features a hollow bore for flushing, or simultaneous drilling and grouting. It is a reliable and
convenient anchoring system which is applied in complicated geological conditions for rock support work. It is widely used in tunneling,
mine, slope stabilization and foundation support. The unconsolidated ground condition favor the rock bolt technique for fast and simple
method of installed compared to the traditional method.
In the construction where the Self drilling rock bolt is used widely, the primary problems are to improve the drilling speed and reduce the cost of engineering. Therefore, it is an relatively ideal choice to adopt the minor diameter Self drilling anchor and high speed drilling.
Generally speaking, if the diameter of the Self drilling rock bolt hole is φ32mm, the corresponding diameter of the Self drilling anchor is φ24mm. According to the construction experience, the height of the loose area in the tunnel vault is about half of the support interval.
