Yesterday (26th) in Guri, Gyeonggi-do, the case where the land was over 20m wide, and we are still unable to find the reason. You need to know the cause to prevent it, but the residents are still anxious.

This is Han Sang-woo.

This is just after a large land shutdown occurred on a road in Guri, Gyeonggi-do yesterday afternoon.

Water flows down like a waterfall from the open tap water, and the ground weakened by the strong current collapses without force.

It was a dizzying moment that almost lead to a major accident because there were no vehicles or pedestrians passing by.

[Recovery site official: I don't know if the water supply was ruptured first or collapsed first. I have to look at all the construction data and all this It is because it rains a lot.] In

Guri City, the ground was weakened due to the long rainy season, and it was considered that there was a high possibility that the ground was turned off due to the rupture of the water supply.

In addition, we are investigating the connection with the subway construction in progress just below the accident site.

However, the Gyeonggi-do and the contractor who ordered the construction argue that the possibility of ground failure due to the construction was low because the vibration was minimized.

[Subway construction officials: This is 1.5m (the point where the land goes off), and we are 30m, and we have never blasted... .] The

ground off point and the subway construction section overlap, but the work was done at a much deeper 30m underground, and the ground was dug by excavation instead of blasting to reduce vibration.

Gyeonggi-do and Guri-si are investigating the cause with civil engineering experts.

Electricity and water supply have resumed, but the round-trip four-lane road is still only accessible in one lane.
