Drill pipe, and system and method for laying a pipeline

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 ...

AI Technical Summary

Problems solved by technology

The problem here is that it is not easy to drill holes directly following the insertion of plastic pipes into the ground, since plastic pipes are not suitable for the non-destructive transmission of the necessary forces, especially in the case of long laying lengths.

Here again, the aforementioned sequential placement is again problematic
