<p>The present invention relates to a staff fixing apparatus for precise leveling, including: a staff provided with gradations on the front surface; a lower-end rotation support unit which is coupled to a lower end of the staff to rotate relatively and horizontally and supports the staff on the ground to be rotated horizontally; an upper-end support fixedly coupled to the upper-end surface of the staff; a pair of rotating arms supported on the upper-end support to be rotated horizontally; an upper-end rotation support unit configured to support the pair of rotating arms on the upper-end support to be rotated horizontally; a pair of legs provided with an upper leg made of a round pipe, connected to an outer end portion of the pair of rotating arms to be rotated vertically, and having upper and lower ends open, a lower leg made of a round pipe, inserted through the lower open end of the upper leg, and having upper and lower ends open, and a landing member coupled to the lower end of the lower leg to land; a leg rotating and connecting unit configured to connect the legs to the upper-end support to be rotated vertically; a leg length adjusting and fixing unit configured to adjust the length of the upper and lower legs and fix the upper and lower legs; and a vertical matching notification unit configured to notify that the staff stands vertically. The staff may be fixed to the ground firmly and stably without vibration with respect to the reference plane, such as a ground control point, a point, etc. and may be maintained in a vertical direction. Once the staff matches the vertical direction at the ground control point or the point, even when the direction of the staff is changed, the staff can be maintained in a vertical direction, thereby minimizing a measurement error during the measurement, enabling precise leveling, and quickly proceeding with precise leveling work.</p> |
