BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground facilities surveying instrument, and more particularly, to an underground facility surveying instrument with easy installation and improved workability.

Generally, geodetic surveying should be done first for various civil engineering design and architectural design.

Geodetic surveying is the measurement of horizontal distance, elevation difference and direction, determining the location of each measuring point, displaying it in figures or numerical values, and staking out all activities in the field.

In recent years, attention has been paid to the accuracy and freshness of data due to the increase of spatial information activity. Especially, recently, data update is secured through DB update that occurred when new waterworks and sewers are replaced.

However, conventionally, when surveying a place where an underground facility or an underground facility is buried, the surveying pole to be erected is easily inclined, so that the surveying operation can not be performed conveniently and accurately.

In the present embodiment, the leading ends 22 are provided with three spacing intervals of 120 [deg.] From each other.

The weights 23 are disposed between the plurality of tip ends 22 and are located above the bottom ends of the tip ends 22. In this embodiment, the weight 23 has a spherical shape, but its shape can be variously modified.

When the pole unit 10 is installed upright on the ground, the plurality of peak portions 22 of the stationary unit 20 are balanced and placed on the ground so that the pole unit 10 stably Can be fixed. Further, the fixing mechanism 20 places the center of gravity of the pole 10 downward via the weight 23, so that the pole 10 is more stably erected. The fastening mechanism 20 is detachably installed on the pole 10 and can be easily replaced when the tip 22 of the fastening mechanism 20 is damaged due to frequent use. Further, at the measurement position where the bottom surface is made of a material such as marble and the bottom surface is not to be damaged, the fixing mechanism 20 can be separated from the pole 10 to perform the surveying work, You can use it to perform surveying tasks.

The GPS instrument 30 is installed at the top of the pole 10. In this embodiment, the GPS instrument 30 is installed at the upper end of the second pole 12 to measure the current magnetic position.

The input / output unit case 40 is installed below the GPS instrument 30, and is installed on the pole 10 so as to be movable up and down. In this embodiment, the input / output device case 40 is provided with a connecting body 41 which is vertically movable on the pole 10 and a fixing body 42 which fixes the connecting body 41 to the pole 10 .
