Abstract: The invention relates to a method for introducing a boring channel in the ground by means of an earth boring device, wherein the earth boring device has a boring head which is moved to introduce the boring channel in the ground, and the method comprises the steps: a) detecting obstacles in front of and/or next to the boring head; b) displaying the position of a detected obstacle relative to the boring head; c) issuing a shutdown warning if the distance between the detected obstacle and the boring head is less than a first, in particular selectable, distance; d) stopping boring of the boring channel when a shutdown warning is issued; e) verifying an acknowledgment for continued introduction of the boring channel when a shutdown warning has been issued and boring stopped; and f) continuing the introduction of the boring channel upon successful verification of the acknowledgment.

Abstract: A rod section having an electrical conductor which is arranged such that it is centered at the end and has an insulating sleeve and is fixed in the rod section such that when the rod section is joined to a further rod section having a fixed conductor, both conductors are joined together in a forcibly guided manner and the join is sealed by the sleeve in a forcibly guided manner.

Abstract: An earth boring apparatus includes a drill rod, a source for a drill fluid, and a voltage source. The drill rod has a hollow rod casing provided for throughflow of the drill fluid, and a conductor located within the rod casing, with the voltage source being connected with the conductor and the rod casing. The voltage source is so connected as to prevent the electric conductor to act as anode in the event the drill fluid establishes an electrically conductive connection between the rod casing and the conductor.
