Abstract: This paper proposes a vertical well plane connection measurement method based on single wire point combined with gyroscope orientation, which is relatively simple compared to the traditional connection triangle method. It can quickly transfer the coordinates of a single point on the ground to the underground, and then provide accurate plane starting datas for underground engineering by adding gyroscope orientation at the starting edge of the underground; The paper analyzes the principle, error sources, and accuracy estimation of this method, and verified it with specific engineering examples; The research results indicate that this method has certain feasibility and effectiveness.
