Shield tunnel segment attitude measuring device

The utility model discloses a shield tunnel segment attitude measuring device, which belongs to the technical field of tunnel engineering measurement and comprises a total station, a leveling instrument and a 360-degree prism. The total station is arranged in the tunnel; the horizontal ruler comprises a ruler body, and the ruler body can be horizontally arranged in a tunnel. The 360-degree prism is connected with the center of the ruler body, and the total station obtains measurement data according to light reflected by the 360-degree prism. According to the shield tunnel segment attitude measuring device, the total station is used for directly measuring the center of the 360-degree prism, the size of the center of the 360-degree prism deviating from the center line of the tunnel is calculated, the horizontal distance from the zero scale of the center of the 360-degree prism to the segment is read, and then the attitude of the segment is obtained through the two data, so that coordinates and elevations of mul
