发明名称 METHOD FOR MAKING A TUNNEL OR GALLERY, AND TUNNELING MACHINE FOR CARRYING OUT THE METHOD
摘要 <p>The method serves to make a tunnel or gallery with a tunnelling machine. So that a method of this type enables the drilling work to be pursued with a tunnelling machine without prolonged clearing and safety work even if the tunnelling machine cuts fault locations, a drill rod (13) is advanced from the drill head (1) in a rotary and/or percussive manner in a radial direction into the rock if fault locations appear and is then left behind. The annular space surrounding the drill rod (13) is filled with a stiffening material. <IMAGE></p>
