AI Technical Summary
Existing methods for dismantling geothermal probes are unreliable due to the rigidity of large-diameter reboring rods, which cannot follow the significant deviations from the vertical alignment of smaller-diameter boreholes, leading to incomplete removal and potential blockages, especially in curved areas.
A method and drilling device using a flexible drill string with a drill bit that can be vibrated and adapted to the probe's curvature, allowing for precise tracking and extraction by rotating and vibrating the drill bit along the probe body, with a flexible pipe section and adjustable frequency and amplitude to reduce friction.
Enables reliable and complete extraction of geothermal probes, even in curved boreholes, by minimizing friction and ensuring the drill bit follows the probe's path, allowing section-by-section removal and sealing of the borehole.
