Problems solved by technology
[0004] The traditional contact measurement generally obtains the vertical line through the hanging ball and transmits the coordinates and direction to the bottom of the pit. This method can accurately obtain the vertical line, but the wind resistance and earthquake resistance are poor, and the vertical ball cannot be stable for a long time
More equipment is used, it takes a long time to complete a test, and it is inconvenient to retest

The present invention relates to the technical field of engineering surveying, and specifically discloses a shaft connection method and a measuring device used for the shaft connection method. Control points are arranged at the wellhead and the bottom of the shaft, and the coordinates of each control point at the wellhead are measured; the elevation is transmitted to Control point A at the bottom of the well, set up a total station at control point B at the center of the well, set up prisms at the wellhead control point and control point A; measure the distance and direction of each control point at the wellhead, measure the direction of control point A and the height of the total station difference; calculate the height difference between the total station and each wellhead control point, use the Pythagorean theorem to calculate the horizontal distance between the total station and each wellhead control point, calculate the angle between adjacent sides, and use the adjustment software to calculate the control point of the total station point coordinates. The invention calculates the horizontal direction through the Pythagorean theorem, avoids the use of vertical angles, and weakens the influence of atmospheric refraction on the calculation of horizontal distances; the measuring device adopted has strong wind resistance and earthquake resistance, and the measurement time is short, and only one device is needed for each re-measurement The total station can be completed in one stop.
Description
technical field [0001] The invention relates to the field of measurement, in particular to the field of engineering measurement. Background technique [0002] In the construction process of underground projects such as tunnels and mines, in order to ensure that the construction is excavated according to the design direction and that the working faces excavated in all directions can be correctly penetrated at the predetermined location, the plane coordinate system and elevation coordinate system of the ground must be passed through the inclined shaft or vertical shaft. Transferred to the subsurface, these transfer jobs are called contact surveys. [0003] The underground and surface surveys have a unified plane coordinate system and elevation system through contact surveys, and at the same time provide coordinates, azimuth angles and elevation initial calculation data for underground surveys. Therefore, it is of great practical significance and value in tunnels, mines and ot...
