Rescuing Hao Nam on January 14: Can't determine the time, explain the adverse factors

At the site of the Roc Sen bridge, hundreds of people and technical means worked day and night, but the rescue work still faced many difficulties. According to experts, it is difficult to give an exact timeline. Currently, Dong Thap province is still implementing a plan in 11 steps to withdraw concrete pillars. The top requirements given are safety, accuracy, and urgency before Tet.

It's been 2 weeks since the 10-year-old boy fell onto the concrete pier at the Roc Sen bridge. The rescue process is always closely watched by the press and public opinion. On social forums, it is not difficult to come across questions: The exact time to bring Hao Nam to the ground, where is the victim located in the 35m-deep concrete pipe... Despite knowing that the family is hot Please wait for the results. However, this is a rare case in Vietnam, so the authorities must carefully discuss it with a team of domestic and international experts. Experts said that withdrawing a 35-deep pile is not too difficult. However, to keep the victim intact and avoid collisions during the rescue is a very difficult problem.

On January 14, the 11-step deposit withdrawal process is still ongoing. According to information from the Health and Life newspaper, the rescue force is digging the ground with a scraper bucket combined with a bucket to grab the outside of the wall pipe; finished cutting 3 ends of the concrete pile, and at the same time lowered and installed the 6th floor frame. In addition to the difficulty of the geological situation as well as the geographical location, the rescue team encountered a problem. Specifically, during the excavation, the 80-ton crane had a problem with the oil pipeline. The operating team at the scene dispatched 3 groups of workers to repair on the afternoon of January 13. In addition, there is a group of workers from Ho Chi Minh City to Dong Thap for maintenance, to ensure continuous operation of the crane.

It is known that the rescue team is in the 2/11 step of withdrawing the stake. This is considered the most difficult step. There is still no exact time to bring baby Hao Nam to the surface.

"This is the most difficult step. That means digging in the steel plank wire, digging while supporting up to 12m below. We are trying to pull out the concrete pipe before Tet. It can be done slowly but must be secured. Safety is first" - Mr. Le Hoang Bao - Director of Dong Thap Department of Transport shared with Health and Life.

The most difficult at present is the geology of the lower strata, hard clay makes digging the soil unfavorable, concrete piles (including 3 connected segments) driven 35m deep into the ground, cutting piles in difficult conditions. tight, narrow. Therefore, it is necessary to change many options in the uprooting of concrete piles.

On the other hand, the scene is located deep in the field, the traffic infrastructure is small and narrow, so the movement of rescue vehicles, equipment and machinery faces many obstacles. In recent days, in Dong Thap as well as in Thanh Binh district, there has been heavy rain, which is detrimental to rescue work. The Rescue and Rescue Operations Team has implemented measures to ensure electrical safety during the construction process for people and equipment at the scene.

As previously reported, at 11:30 a.m. on December 31, 2022, little Thai Ly Hao Nam and 3 other friends entered the Roc Sen bridge to pick up iron. At this time, the security guard discovered it, so he kicked it out. However, taking advantage of the security guard to take a lunch break at 11:50 am, the group of children continued to sneak in. Unfortunately, baby Hao Nam fell on a concrete pillar with a diameter of 25cm. On January 4, based on unfavorable factors, Vice Chairman of the People's Committee of Dong Thap province Doan Tan Buu confirmed that Hao Nam did not survive.

The case of baby Hao Nam falling on a concrete pillar 35m: Entering the 10th day, still not able to bring the body up Rosé11:12:25 10/01/2023Ask the question why the rescue and rescue takes so long? Mr. Bao said, pulling up a concrete pile 35m deep from the ground up is not simple.
