BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of a vertical detector according to the present invention will be described below with reference to the drawings. It should be noted that the same or equivalent parts as those of the conventional example are designated by the same reference numerals for description. Similar to FIG. 8, FIG. 1 shows a pillar 3 vertically arranged in a hole or the like formed in the ground, and a pair of vertical detectors 6 are attached to the sides of the pillar 3. The parts 4 and 5 are detachably provided. In the case of the first embodiment shown in FIG. 2, the vertical detector 6 is provided with a universal bearing 8 made of a well-known spherical bearing on the upper end 7a of a cylindrical case 7, and the operating body of the universal bearing 8 is A well-known inclinometer 9 is provided on the upper part, and a long rod 10 is provided on the lower part. The rod 10 hangs down in the space 7b of the case 7, and the lower end 10a of the rod 10 is provided.
The lower end 7c of the case 7 and the wire 11 and the spring 12
And are connected by. Therefore, the mounting surface 9b of the inclinometer 9 is orthogonal to the axis 9a. Therefore, when the vertical detector 6 of FIG. 2 is attached to each of the mounting portions 4 and 5 of the pillar 3 of FIGS. 1 and 8, the vertical state of the pillar 3 is detected by the inclinometer 9, and the detection data is not shown. It is quantitatively stored and saved in the device. In this case, even if the case 7 is distorted as shown in FIG.
9b is orthogonal to the axis 9a. Further, the balance weight 9d of the inclinometer 9 is for removing the moment related to the universal bearing 8.

Next, the configuration shown in FIG. 5 shows the second embodiment, and only the configuration different from that of FIG. 2 will be described. That is, the universal bearing 8 is composed of a well-known biaxial gimbal (shown in FIG. 4), the inclinometer 9 is attached to the actuating body 8a of the biaxial gimbal, and the lower end 10 of the rod 10 is attached.
A mass 20 is hung on a through a wire 11.

The mass 20 is located in the liquid 21 for damping in the case 7, and the distance sensor 22 attached to the inner wall of the case 7 measures the distance between the distance sensor 22 and the mass 20. By detecting, the vertical state of the pillar 3 is detected. Therefore, FIG.
In the case of,
One or both of the two can be used for detection.

In the case of the third embodiment shown in FIG. 6, a television camera 30 is provided at the upper end 7a of the case 7, and a float 25 is provided in a floating state in the liquid 21 provided in the case 7.
