Embodiment 1

[0058] Such as figure 1 As shown, this embodiment needs to measure the verticality, flatness, verticality deviation and verticality comprehensive deviation of the wall 102. The height of the wall 102 is 30m. The top corner point A on the wall 102 is now selected for illustration.

[0059] The method of expanding the application of the total station, the specific steps are as follows:

[0060] A. The total station 101 sets up a station at the free measuring point O' and establishes a free coordinate system X'O'Y', and the total station 101 is an infrared total station;

[0061] B. Establish a standard coordinate system XOY, the X axis of the standard coordinate system XOY is parallel to the wall 102, the Y axis of the standard coordinate system XOY is perpendicular to the wall 102, the distance between the origin O of the standard coordinate system XOY and the wall 102 on the Y axis is 0.01m;

[0062] C. Use the total station 101 to detect the coordinates (0.005, 0.018) of...

Embodiment 2

[0084] Such as figure 2 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the origin O of the standard coordinate system XOY coincides with a corner point of the wall 102, and at this time the origin O of the standard coordinate system XOY is away from the wall on the Y axis The distance of the surface 102 is , which simplifies the calculation process of perpendicularity and flatness, and the verticality and flatness can be directly obtained by reading the coordinate values ​​of the measured points, which improves the measurement efficiency.

Embodiment 3

[0086] This embodiment is basically the same as Embodiment 1, except that the eyepiece of the total station 101 is a curved tube eyepiece. The curved tube eyepiece is used to solve the problem that the total station 101 cannot observe due to the excessive elevation angle.

Abstract

The invention discloses a method for expanding application of a total-station instrument. The method includes steps of A, setting a station for the total-station instrument at a free measuring point O' and establishing a free coordinate system X'O'Y'; B, establishing a standard coordinate system XOY; C, detecting coordinates (Xn', Yn') of a measured point on a wall surface in the free coordinate system by the aid of the total-station instrument; D, converting the coordinates (Xn', Yn') of the measured point in the free coordinate system into coordinates (Xn, Yn) in the standard coordinate system; and E, computing the perpendicularity, the flatness, the deviation of the perpendicularity and the comprehensive deviation of the perpendicularity. An X-axis of the standard coordinate XOY is parallel to the wall surface, and a Y-axis of the standard coordinate system XOY is perpendicular to the wall surface. The method has the advantages that safety risks due to measurement by the aid of scales are avoided, the method is wide in measurement range as compared with a measurement method by the aid of the scales, the full range of the wall surface can be measured, the measurement precision is improved, the measurement time is shortened, and the measurement efficiency is enhanced.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a method for using a total station, in particular to a method for measuring verticality, flatness, verticality deviation and verticality comprehensive deviation by a total station. Background technique [0002] During the construction and use of buildings, internal deformation will inevitably occur. Deformation is acceptable within a certain degree, if the deformation exceeds a certain range, it will affect the normal use of the building, and even endanger the safety of the building. The deformation of the building is mainly reflected in the changes of the verticality and flatness of the building. Therefore, it is particularly necessary to monitor the verticality and flatness of the building. During the construction process, it is even more necessary to ensure the verticality and flatness of the building. degree is within the specified range. [0003] In the past, when t...
