摘要

The device has an annular space provided between drill pipes and a liner. An injection head is connected with a drill string in a region of a leading end of the drill string. A stator (400) is arranged in a region of a posterior end of the drill string. A rear portion of the drill string is rotatably guided in the stator. A bonding agent fluid connection (420) is arranged in the region of the posterior end of the drill string. A solidification accelerator fluid connection (430) is provided in the region of the posterior end. An independent claim is also included for a method for drilling and stabilizing a borehole.
