发明名称 Automated bore planning system for horizontal directional drilling
摘要 Systems provide for electronic development of a bore plan for use in connection with an underground boring machine. Electronically developing a bore plan involves providing topographical information representative of topography of the bore site and providing bore path information representative of an intended bore path for the bore site. The bore path information includes at least two target points through which the intended bore path is to pass. The intended bore path can define a pilot bore path or a backream path. The target points comprise an entry point and an exit point, and each of the target points is defined by at least a distance value, lateral value, and a depth value.
