Method for producing a horizontal bore in the ground and horizontal drilling device

摘要

A method for producing a horizontally drilled bore hole in the ground includes the steps of producing a pit having a circular cross-section; lowering a horizontal drilling device into the pit, the horizontal drilling device having a circular cross-section in at least part of the section in which it is positioned once it is lowered into the pit; and producing a horizontally drilled bore hole using the horizontal drilling device.

主权项

1. A method for generating a horizontal bore in the ground comprising the steps of:
generating an excavation pit having a circular cross section; lowering a horizontal drilling device, including a linear drive for driving a rod assembly, into the excavation pit, wherein the horizontal drilling device includes a housing surrounding the linear drive, the housing being configured at least partially cylindrical in section at least a section in which the housing is arranged within the excavation pit in an operation condition of the horizontal drilling device; suspending the horizontal drilling device within the excavation pit by at least one support device comprising a plurality of support legs arranged on a surface of the ground and coupled to a section of the housing arranged above a surface of the ground, the plurality of support legs extending radially outward from the housing and substantially symmetrically around the excavation pit to support the horizontal drilling device; and generating the horizontal bore with the horizontal drilling device.
