Abstract

The invention relates to a method for rock and/or soil reinforcement, comprising drilling of a hole for cement or corresponding grouting material to be injected about a rock bolt that is to be grouted in the hole. The invention suggests a hollow rock bolt to be formed in one end with a male thread and a female thread in the other end; a drill bit formed with a male thread and supported in the female threaded end of the rock bolt; the hole being drilled with the female threaded end of the rock bolt facing the drilling direction, and the rock bolt being anchored by a nut connected in the male threaded end of the rock bolt. An extensible, drilling rock bolt is suggested for carrying out the method, the rock bolt comprising a hollow shank formed with external threads, one end of the rock bolt being formed with a male thread and a female thread being formed in the other end, the female threaded end supporting a drill bit formed with a male thread.
