These drilling templates can be pre-concreted. Alternatively, transportable drilling templates can be provided, which are introduced into the ground. Such drilling templates are for example from the US 6,394,709 B1 , of the JP 2000/319881 A or the CN 10-0989853 A known. The formation of drilling templates in the soil is time consuming and costly.

These casing machines have clamping clamps for non-rotatably clamping a support tube. By a rotary drive of the casing machine, the clamped support tubes can be screwed by means of the clamps in the ground. These support tubes can then serve as a guide for a drilling tool to be used to drill out the soil material within the support tube.

Rather, it is provided according to the invention, spaced from the mast and the rotatable superstructure on the undercarriage of the drill, so the chassis to provide a drill guide with a drill sleeve.
  • the drill with the relatively stiff undercarriage is positioned so that the guide sleeve has the desired position according to a drilling template.
  • the superstructure with the mast which is subject to deflections due to its height and a desired light construction possible during operation, pivoted to the guide sleeve and adjusted so that a center axis of the guide sleeve is aligned coaxially to the drilling axis of the drilling tool.
  • the drilling tool can then be rotated and passed through the guide sleeve to create the borehole.
