Embodiment Construction

[0049] figure 1 An isometric view of a horizontal drilling device 1 according to the invention is shown for introducing a pilot borehole into the soil.

[0050] The horizontal drilling device comprises a cylindrical housing 2 which is partially closed via a cylindrical jacket 3 . Functionally, the horizontal drilling device 1 or the housing 2 of the horizontal drilling device 1 is divided into two sections, namely a lower section called the "pit section", which is located in a section specially designed to receive the horizontal drilling device. 1 in the excavated foundation pit 4 . In the excavation section of the horizontal drilling device 1 , the housing 2 is substantially completely closed by the casing 3 . This prevents soil loosened from the walls of the excavation 4 from falling into the cavity formed by the housing 2, where the other functional elements of the horizontal drilling device 1 and in particular a combined linear / rotary drive are located 5. Otherwise soi...

Abstract

The invention relates to a method for operating a horizontal drilling device which comprises a linear drive, a rotary drive that can be displaced by means of the linear drive, and drill pipes that are designed as a string of drill pipes from a plurality of interconnected pipe strands, the rotary drive forming a through-opening into which the drill pipes can be inserted. The through-opening is provided with force transmission means for transmitting compressive and / or pulling forces and / or a torque onto the drill pipes. The invention is characterized in that a pipe strand is fixed inside the through-opening of the drill pipes and is connected to the rear end of the drill pipes or detached from the drill pipes by a linear and / or rotary movement of the rotary drive.

Description

technical field [0001] The invention relates to a method for operating a horizontal drilling device and to a horizontal drilling device. Background technique [0002] Horizontal drilling devices are used to introduce supply and discharge pipes into the soil without digging or to replace old pipes that have already been laid without digging. [0003] There are a large number of different horizontal drilling devices. Widely used are horizontal drilling devices in which a drill head is first drilled obliquely into the soil with the aid of a drill rod and starting from a drilling support positioned on the ground until the drill head reaches the required drilling distance. hole depth. The drill head is then turned towards the horizontal to perform the actual horizontal drilling. The target point of such a horizontal drilling can for example be in a target excavation dug out for this purpose or in a basement or it can also be on the ground just like the starting point, so that ...
