Description

Method and System for Detecting Excavation Work on Underground Pipelines The present invention relates to a method and system for detecting excavation work in underground pipelines, and more specifically, to a method and system capable of detecting whether excavation work is occurring at any time without requiring a report on the excavation work. Underground pipelines require maintenance. In particular, thorough management is necessary for underground pipelines carrying city gas or high-temperature water, as damage can lead to major accidents and cause immense harm, including casualties. One of the major factors significantly influencing the deformation or breakage of underground pipelines is physical damage caused by underground excavation work. When excavating, construction must be reported to ensure that special care is taken regarding the location where major pipelines, such as gas pipelines, are buried. However, there are cases where excavation is carried out without reporting, or where excavation is conducted in a location where it was believed there were no pipelines according to the underground pipeline design, only to discover that underground pipelines constructed differently from the design exist and are damaged by being struck. Therefore, it is necessary to develop technology to detect whether there is unreported excavation work or excavation work at unexpected locations regarding underground pipelines. Conventional vibration detection devices associated with excavation work are installed and operated separately by a pipeline safety manager on the road surface above the pipeline at the reported construction site during the construction period. In this process, the vibration detection device detects vibrations from the ongoing construction to prevent damage to the buried pipeline caused by worker error. However, conventional vibration detection devices related to excavation work are installed and operated arbitrarily for reported excavation projects; therefore, continuous monitoring and detection of unauthorized excavation work or pipelines not included in the drawings is not possible, and thus, technological development for this is being requested.

FIG. 2 is a diagram illustrating a process for collecting natural vibration information according to an embodiment of the present invention.
