Description

A geodetic surveying device that can be easily installed on the ground with a standard for geodetic surveying.

The present invention relates to a geodetic surveying apparatus, and more particularly, to a geodetic surveying apparatus capable of easily installing a standard for geodetic surveying on the ground.

In general, for public surveys and underground facility surveys ordered by public institutions such as the state, geodetic surveys should be performed first. Geodetic surveying refers to all activities of measuring the horizontal distance, elevation difference, and direction, determining the position of each measurement point, displaying it in drawings or numerical values, and staking out on-site.

Among these geodetic surveys, level survey is a survey to find the difference in height between two points using a survey device such as a target, leveler, and total station, and its accuracy is 5mm * S/2 (here, S is the one-way distance, and the unit is km), so detailed measurement is required.

1 is a view for explaining a method of measuring a level using a conventional standard and measuring instruments, Figure 2 is a perspective view showing the state of the conventional standard.

In the first step, the target number 1 is set at the ground reference point (a0) of known altitude, and the machine number (機械手) is a level machine, etc. Read the scale of the target scale (1) with the measuring instrument (2).

In the second step, the target number moves to the first point (a1) and sets up the target scale (1), and the machine number changes the direction of the surveying device (2) at the observation point (b1) and passes the first through the surveying device (2) Read the mark scale of the point. Here, the altitude of the first point is obtained from the difference between the scale read at the ground reference point (a0) and the first point (a1) and the altitude of the ground reference point.

In the third step, the machine number moves to the second viewpoint (b2) behind the first point (a1), and the reference number 1 changes the direction from the original position (the first point), so that the measurement number 1 is surveyed. When looking at the device 2, the machine operator reads the scale scale of the first point a1 with the measuring device from the second observation point b2.

In the fourth step, the target scale moves to the second point (a2) and sets the target scale (1), and the machine number reads the scale scale of the second point (a2) at the second observation point (b2). Here, the altitude of the second point is obtained from the difference in scale between the first point (a1) and the second point (a2) read from the second observation point (b2).

In this way, while continuously moving the target scale (1) and the measuring device (2), the direction of the target at each point and the measuring device at each observation point is changed, and the scale is read to obtain the altitude of each point to the target point.

At this time, in order to perform accurate geodetic surveying work, the surveying device must be able to stably maintain a horizontal posture, and must not be shaken even when an external shock or vibration is applied.

However, the conventional target is a combination of a plurality of scale bars so that the length can be adjusted in a slide telescopic type, and the vertical installation of the target depends on the experience of the target or the signal sent by the machine to the target while observing the target. For this reason, it is difficult to accurately install the mark vertically.

In addition, in the conventional target, in the process of changing the direction of the target in the third step, the target must be lifted from the ground to change the direction of the target, and then put down again in the original position. There is a problem in that it is often not possible to put down the instrument accurately in its original position, and accordingly, a measurement error occurs.

Furthermore, in the case of geodetic surveying over a large area, the number of reference points is the ground reference point (a0), the first point (a1), the second point (a2), the third point (a3).... Since it is necessary to set the target at the correct point each time it is moved, there are problems such as extreme fatigue in the work of the target and the delay of the work.
