BANGKOK: A Myanmar worker died after soil slid into a deep underground cable-duct shaft in Bang Na late Feb 4. Forensics and police are investigating.
A Myanmar worker was killed after soil collapsed and slid into a deep underground shaft at a construction site in Bangkok’s Bang Na area, where crews are working on a project to move overhead power lines underground.
Rescue volunteers said the incident occurred late on Feb 4, 2026. The worker was buried in mud at the bottom of the shaft, in an area described as soft and waterlogged, raising concerns about further subsidence during rescue operations.
Aniwat Sirichokphatthanakit, a rescue volunteer with the Ruamkatanyu Foundation, said the team was alerted at around 11.30pm via the 191 emergency hotline and rushed to the site.
Coworkers told rescuers they had attempted to help for around 30 minutes before volunteers arrived, but the victim had been buried under soil and lost consciousness.
When rescuers went down to check, they found no signs of life. They deployed high-angle rescue equipment and a stretcher to retrieve the body, and the recovery took about an hour, according to the rescue team.
Witnesses and site staff told police that only one worker was affected, as the victim had been working below ground at the time.
A supervisor said workers were excavating inside the shaft at a depth of roughly 8–10 metres and were attempting to dig down to around 14–15 metres when soil on both the left and right sides gave way and collapsed onto one worker. Others tried to help as best they could.
Police have coordinated forensic officers and a forensic doctor from Chulalongkorn Hospital to examine the scene. Investigators said they will summon the supervising engineer and other parties connected to the project for questioning to determine the cause of the incident.
The body was sent for a post-mortem examination at Chulalongkorn Hospital’s forensic unit before being released to relatives for religious rites.
The underground power-line project is being carried out along Sukhumvit Road, from the Bang Na intersection to the entrance of Sukhumvit Soi 107, with construction scheduled from Dec 1, 2025, to July 31, 2026. Work is typically conducted overnight from 10.00pm to 5.00am. - The Nation/ANN
