摘要： PROBLEM TO BE SOLVED: To provide a surveying device capable of efficiently realizing highly precise surveying, and suitable to be used for a pipe jacking method. SOLUTION: This surveying device S is provided with a device main body 10 arranged so as to be freely revolvable in a horizontal direction in a set state, a measuring function part 30 arranged so as to be freely resolvable in a vertical direction in the device main body 10, an optical range finding part 33 arranged in the measuring function part 30, a reflecting part 34 for range finding arranged in the measuring function part 30 in a vertical face in which the collimation direction of the optical range finding part 33 is included, an angle measuring light irradiating part 38 arranged in the measuring function part 30 for irradiating light beams for angle measurement to the same direction as the collimation direction of the optical range finding part 3, and an angle measuring light receiving part 36 arranged so as to be made adjacent to the angle measuring light irradiating part 38 in the measuring function part 30 for receiving the light beams for angle measurement.
