Uljugun to Launch Survey Project to Prevent Ground Subsidence and Voids

Urban Planning Road Pilot Survey to Be Expanded Nationwide

Ulsan Ulju-gun announced on the 28th that it will promote a joint survey service for underground road facilities and surrounding ground to prevent safety accidents caused by ground subsidence and voids.

According to the “Special Act on Underground Safety Management” (enforced in January 2022), managers of underground facilities with pipelines of 500mm diameter or more must conduct safety inspections of their facilities and the surrounding ground.

However, in the case of Ulju-gun, most underground facilities have a diameter of less than 500mm, making it necessary to take proactive measures to prevent ground subsidence and void formation.

Through this service, Ulju-gun plans to conduct ground-penetrating radar (GPR) surveys beneath roads.

After conducting pilot surveys on urban planning roads such as back roads in residential areas in Dongburi, Eonyang-eup and Daean-ri, Onyang-eup, the county plans to expand the surveys throughout Ulju-gun based on the results.

If the cause of the voids is identified through the survey, the facility managers for water supply, sewage, electricity, telecommunications, and gas will carry out excavation and restoration. If the cause is unclear, the Ulju-gun Road Division will handle the restoration.

An official from Ulju-gun said, “We will identify risk factors for road subsidence and prevent ground subsidence accidents by utilizing advanced ground survey technology,” adding, “We will do our best to create a pleasant road environment.”
