The present invention relates to a geodetic surveying system for locating underground facilities that can statistically analyze various types of information in the required form.

In modern times, due to the improvement of social, cultural and industrial standards, underground areas near residential areas have numerous underground areas such as water and sewage pipes including gas pipes, oil pipelines, communication and power cables, various ducts and storage tanks. Facilities are present.

In Korea, the high-pressure pipe network of 10 ~ 70㎏ / ㎠ operates over 1,300km as of the end of 1997, and it is expected to reach 2,000km within a few years. Therefore, the location information must be accurately identified for the repair and management of underground facilities. Of course, it is necessary to manage effectively according to the records, but the degree of damage caused by various accidents occurring during various constructions due to lack of accuracy is increasing continuously.

There are many factors that can damage the safety of underground facilities. Among them, damage caused by excavation work (excavator, drilling machine), ground subsidence, and electrical corrosion by leakage current from subway or other underground facilities are mentioned. have.

To establish countermeasures, it is essential to first identify the location of underground facilities.In order to suppress the risk of excavation work, it is best to identify and notify the exact location of various facilities at the time of approval before construction. to be.

Conventionally, when underground facilities are buried, before filling up the soil, one of the measuring workers supports the target while another worker checks the position of the target using public survey equipment such as a total station on the ground. Although it uses a method or a surface, it has a problem that it is difficult to expect accuracy.

In addition, the method of using a pipe locator is the most commonly used method, which has the advantage of being relatively accurate and simple, but in the case where facilities are complicatedly buried, such as downtown, the accuracy is greatly reduced due to interference. Has advanced to the point of using GPR exploration equipment.

This method uses high frequency electromagnetic wave and received signal processing method to detect the position of the object, but it is a device that detects various structures and stratum structures existing in the basement, but the overall configuration of the equipment is complicated and considerable experience to accurately analyze the detection result. There is considerable difficulty in commercialization because the detection results are very sensitive depending on the soil properties.

These underground facilities can be managed by geographic information system (GIS).
