Coordinate transfer method for shaft excavation construction

A coordinate transfer method for shaft excavation construction is provided. A first total station and a second total station are included; the first total station is set up on the upper horizontal section of the shaft; the second total station is set up on the bottom of the shaft; the first total station detects the laser point coordinates projected on an upper bending section, so as to set up the second total station and realize coordinate transfer. The method includes the following steps: 1) respectively setting up the first total station and the second total station on the on upper horizontal section and the bottom of the shaft; 2) acquiring the coordinate of a point A; 3) acquiring the coordinates of a point B; 4) setting the second total station according to the coordinates of the two points in the steps A and B; 5) comparing the coordinate of a point C measured by the first total station and second total station, and controlling the error in an allowable range, so as to complete coordinate transfer; and
