It has been revealed that one out of every two sewers buried under Seoul is over 30 years old. The roads we walk on every day are like a ticking time bomb, uncertain when they might collapse. Reporter Kim Min-soo has the story. 【 Reporter 】 Restoration work is underway on an 8-lane road in downtown Seoul, which has been partially closed. On the 13th, a motorcyclist passing through this area reported concerns about potential subsidence. Although the road was only about 2 cm deep, it was determined not to be subsidence, yet citizens remain anxious. ▶ Interview: Kim Sung-won / Jung-gu, Seoul "Ground subsidence has been happening a lot lately. While walking, it could just suddenly collapse. It’s concerning." Seoul City has launched emergency measures, including deploying GPR survey vehicles to analyze a 45km section by the end of this month. The GPR survey vehicles are equipped with surface imaging cameras and antennas, operating at speeds below 30 km/h. By sending electromagnetic waves underground and analyzing the reflected signals, they can detect irregularities such as underground voids up to 2 meters below the surface. ▶ Standing: Kim Min-soo / Reporter "Data from 2 meters underground is being collected by the antenna attached to the rear of the vehicle. The collected information is displayed visually on this monitor screen." Among the 12 subsidence incidents that occurred until last month, 5 took place in Seoul. The total length of Seoul's sewer system is 10,866 km, with more than half, 6,028 km, being over 30 years old, and 30.4% being over 50 years old, indicating serious deterioration. As the aging pipes cannot withstand the pressure from the surrounding soil that freezes and thaws, replacing them has become an urgent challenge, even more so than their detection.
