Local authorities were still racing against time on Tuesday to rescue a 10-year-old boy trapped in a 35m-deep concrete pipe pit in Vietnamโs southern province of Dong Thap since Saturday afternoon.
Thai Ly Hao Nam and three other children had gone to the Roc Sen bridge construction site to collect scrap metal on Saturday, but he fell into the concrete pillar that had an opening of just 25cm in diameter.
Soldiers and engineering experts were mobilised to try to free the boy, with rescuers hoping to raise the hollow pillar from its 35m-deep hole and cut the boy out โ though after being trapped inside for four days, it is not clear whether he is still alive.
A wider 19m-long metal pipe has been lowered around the concrete tube in which Nam is trapped to allow them to remove mud from around the pillar and try to lift it out.
Rescue equipment like excavators, cranes and augers was deployed.
Rescuers were softening and removing mud and water to reduce pressure around the pillar before bringing it up โ most likely later on Tuesday evening.
Cylinders of oxygen have been brought to the scene to help the boy breathe.
Water was also given to the boy but there was no sign that he was using the water since Sunday morning, according to Phu Loi Communeโs Peopleโs Committee.
Around 100 soldiers and professional equipment have been sent to the site, which has been sealed off from the public while the rescue effort goes on.
โThe boy has been trapped inside the small pillar for four days, with assumption of multiple injuries. Hope for him to be alive is limited,โ said Mr Doan Tan Buu, deputy chairman of the Dong Thap provincial peopleโs committee.
The rescue efforts over the weekend have so far had no success.
โWe had tried our best to rescue the boy using on-the-spot measures and equipment,โ said Mr Buu.
โWe later had to report and ask for help from national levels and people with expertise,โ Mr Buu was quoted as saying by state-controlled Tuoi Tre newspaper. (StraitsTimes)
