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.

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.

Therefore, it is necessary to change many options in the uprooting of concrete piles.

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.
