Embodiment Construction

[0072] 1A, 1B show a side view of a first embodiment of a drill pipe 10 according to the present invention. The drill pipe 10 has a first connecting section 11 at its first end and a second connecting end 12 at its opposite second end, wherein the first connecting section 11 and the second connecting section Section 12 corresponds to each other because these connecting sections can be connected to each other or plugged together. The first connecting section 11 and the second connecting section 12 are arranged here such that they form a flange connection system in the first embodiment of the invention, wherein the first connecting section 11 has a supporting section 13 in which the supporting A hole 14 is provided in the section. On the rear side of the supporting section 13, a recess 15 is provided in the outer wall 16 of the drill pipe 10. (See Figures 2A to 2D). In the recessed portion 15, a void 17 is provided corresponding to the hole 14. In addition, a hole 18 is provi...

Abstract

The invention relates to a drill pipe (10) for use during the creation of a borehole in a ground (100) from a starting point (101) to a target point (102) along a predetermined drill line, in particular for the near-surface laying of underground cables or electric underground cables in the ground (100). The invention is characterized in that the borehole is gradually created by means of a drillingdevice (103, 106) that has a drilling tool for loosening the ground when the drill pipes (10) are advanced, each end of the drill pipe having at least one connection section (11, 12) for detachably connecting it to a further element of a drill string (110) in a tensile resistant manner; in that the drill pipe (10) has at least one element (21) for producing a tensile-resistant connection to a corresponding element of an advance device for advancing the drill pipe into and/or retracting it from the borehole; and in that an outer wall of the drill pipe is made in one piece. The invention further relates to a device (103) for moving at least one drill pipe into a borehole or out of the same, and to a system and a corresponding method.

Description

Technical field [0001] The present invention relates to a drill pipe, which is used to drill holes along a predetermined drilling line in the soil from a starting point to a target point, especially for laying underground cables or ground wires in the soil close to the surface, Wherein, the hole is drilled with the aid of a drilling device having a drilling tool, which is used to make the soil fall off when the drill pipe advances. In addition, the present invention also relates to a device, which is used particularly in the case of drilling a hole close to the surface from the starting point to the target point in the soil and / or when placing pipes or ground wires or underground cables from the starting point To the soil at the target point or vice versa, move at least one drill pipe into or out of the borehole, the device has: at least one base; at least one support; At least one actuator for the movement of at least one drill pipe, the actuator is operatively connected with ...
