Guide frame for guiding a cutting apparatus within a pipe incorporated into the ground, comprising:
- a framework body which can be inserted into the pipe and comprises a guide, along which the cutting apparatus can be displaced,
- a bracing means for tensioning and fixing the framework body in the pipe, and
- an adjusting means, with which the cutting apparatus can be adjusted within the pipe in a transverse direction relative to the pipe axis,
- wherein
- a diameter of the pipe is larger than a diameter of the framework body,
- the framework body comprises a receiving space for receiving the cutting apparatus and a first stop, by means of which the guide frame can be supported and carried on the cutting apparatus, whereby the first stop is arranged on a bottom end of the framework body, and
- the cutting apparatus comprises a second stop, on which the first stop of the framework body lies.
Method for anchoring a pipe in the ground, comprising the following steps:
- driving the pipe into the ground,
- inserting a guide frame with a cutting apparatus mounted thereon into the pipe and lowering the guide frame within the pipe,
- tensioning the guide frame within the pipe, and
- removing earth within the pipe by driving in a rotating manner at least one cutting wheel of the cutting apparatus and axially lowering the cutting apparatus within the guide frame,
- wherein
- the guide frame comprises a framework body,
- a diameter of the pipe is larger than a diameter of the framework body,
- the framework body comprises a receiving space for receiving the cutting apparatus and a first stop, by means of which the guide frame can be supported and carried on the cutting apparatus, whereby the first stop is arranged on a bottom end of the framework body, and
- the cutting apparatus comprises a second stop, on which the first stop of the guide frame lies.
Apparatus for removing earth within a pipe at least partially incorporated into the ground, comprising:
- a cutting apparatus;
- and
- a guide frame for guiding the cutting apparatus within the pipe incorporated into the ground, comprising:
- a framework body which can be inserted into the pipe and comprises a guide, along which the cutting apparatus can be displaced,
- a bracing means for tensioning and fixing the framework body in the pipe, and
- an adjusting means, with which the cutting apparatus can be adjusted within the pipe in a transverse direction relative to the pipe axis,
- wherein
- a diameter of the pipe is larger than a diameter of the framework body,
- the framework body comprises a receiving space for receiving the cutting apparatus and a first stop, by means of which the guide frame can be supported and carried on the cutting apparatus, whereby the first stop is arranged on a bottom end of the framework body, and
- the cutting apparatus comprises a second stop, on which the first stop of the framework body lies.
