Explaining the case that little Hao Nam can fall on a concrete pillar with a diameter of 25cm, it is recommended to use a large crane

Worker Doan Tuan Em, 33 years old, from Ca Mau, said that 18 concrete pillars were finished, and workers used soil to cover them. From the ground to the mouth of the concrete pillar is 2-3m thick. Therefore, according to Tuan Em and many other workers, they could not explain why there was a "death pit" that caused Nam to fall.

On the 6th and 7th of January, leaders of Dong Thap province and other specialized agencies continuously came to the scene to grasp the situation and direct the work of bringing the boy into the concrete pillar 35m deep to the ground. As recorded at the scene, the rescue, rescue and security forces continued to work urgently.

After evaluation and discussion, the experts at the site proposed a number of possible solutions to pull the concrete pillars to the ground. The proposed option that is most agreed upon by experts is to use a combination of steel sheet piles and steel wall pipes in the process of cleaning the soil around the concrete pillars.

On January 7, Dong Thap Provincial People's Committee had a meeting with the Ministry of Construction and Transport on the plan to pull out the concrete cylinder that Thai Ly Hao Nam fell down. At the meeting, Dong Thap province agreed on the plan of uprooting the piles through 11 steps.

Accordingly, the piling stage has two more 2m and 1m diameter wall pipes that are driven down to cover the concrete pile pipe. Besides, the soil around the wall cage is softened and sucked out.

According to the evaluation of the rescue unit, this new option meets the aspects of time, safety and utilization of on-site equipment. To pull up the concrete cylinder, the rescue team needed to add an 80-ton crane or at least an additional 50-ton crane to the scene. Currently, at the site, there are two cranes of 50 tons and 35 tons.

According to research, before that a crane with a tonnage of about 120 tons was proposed to be put on the scene. However, because the rescue site is located in the middle of the field, small rivers cannot enter, so this option is not feasible. Up to now, the rescue work of Hao Nam has entered the 8th day but has not achieved the expected results.

Photos and videos record the scene of saving the boy at the beginning, revealing the mound with a "death" pit, the crater is about 60-70cm. This is the reason the boy fell into the concrete pillar 35m deep into the ground. But why is there this "death" hole at the construction site?

According to a worker involved in piling work at the construction site, his construction team carried out the driving of concrete pillars on both sides of Kenh Roc Sen bridge abutment. This work has been carried out by the construction team from November 2022, each abutment is built with 18 concrete pillars 35m long. On December 29, the last pillar on the right bank of the Roc Sen Canal (on the side of the grandson's concrete pillar) was completed.

Worker Doan Tuan Em, 33 years old, from Ca Mau, said that 18 concrete pillars were finished, and workers used soil to cover them. From the ground to the mouth of the concrete pillar is 2-3m thick. Therefore, according to Tuan Em and many other workers, they could not explain why there was a "death pit" that caused Nam to fall.

However, Mr. Tuan Em and Mr. Hoang Anh Viet - workers in the piling construction team - said that the soil cover on the concrete pillar may be eroded by vehicles moving back and forth, because of the time before There was an accident, it didn't rain. "When the pile is finished, you have to fill it with soil, simply to protect yourself from falling. An open pier may be caused by moving vehicles (each weighing over 60 tons) causing vibrations. ", Tuan Em said.

Anh Viet further shared, when the team moved to the opposite riverbank to build piles, at this time workers and machinery gathered on the opposite bank. When driving the first pile, it happened that the grandson fell through the concrete pillar.

The above explanation is just one side from those present at the scene. Public opinion is still waiting for an answer from the functional sector about the responsibilities of the construction unit, project manager and supervisor of this work when a serious accident occurs.

Answering the question "Do the authorities prosecute the case to investigate or not", Mr. Doan Tan Buu - Vice Chairman of Dong Thap Provincial People's Committee said: Currently, the province is focusing on rescue work and solving difficulties. family towels. The responsibilities of specialized agencies related to this work incident will also be updated to resolve in accordance with the law.
