On January 16, the rescue work of a b.oy trapped in a concrete pillar 35 m deep entered the 17th day. Rescue work is still being carried out urgently before the approaching Lunar New Year.

The rescue operation team of the Roc Sen bridge is still digging the ground with a scraper. During the excavation process, the force used bentonite to stabilize the wall to a depth of -19 m compared to the top of the concrete pile (the remaining 5 m is to the 3rd pile burner).

Due to the large free length of the pile head, it is necessary to cut the joint 1 and bring up the first part from the foundation pit, seal the pile head of section 2 at dawn on the same day to prevent the pile from tipping over.

The executive team shared that on January 15, the functional force dug the ground in the pit of the steel plank frame. Due to the hard soil, sticking to the equipment, the progress is slower than expected.

According to the plan, on January 16, when the ground work is completed, the D2000 steel wall pipe will be lowered with a vibrating hammer to surround the concrete pillar instead of the previously withdrawn D1600 steel wall pipe. It is expected that the D2000 steel wall pipe will close to a depth of 26m.

Talking to Dan Tri reporter, Mr. Le Hoang Bao - Director of the Department of Transport, Head of the Rescue and Rescue Operations Team of the Roc Sen Bridge project said: "Up to the present time, the rescue work is , taking the b.oy out is on the right track. However, in the process, we missed a step of not using the D1000 wall pipe".

The rescue and rescue of the Roc Sen bridge worked day and night, even pouring rain to construct with the aim of bringing victims to the ground as soon as possible.

At 3:30 on January 16, the construction team lifted the first part of the concrete pillar, where the b.oy fell into the deep hole.

Thus, after 17 days of the incident at Roc Sen bridge, Phu Loi commune, Thanh Binh district, Dong Thap province, the b.oy has not been brought to the ground.

At the same time, the operating team added additional equipment for work such as earth scraper bucket, 80 ton crane, bored pile drill head with diameter of 0.6 - 1m, wall pipe with diameter of 1m and 2m, ...

Previously, on January 7, the People's Committee of Dong Thap province held a meeting with experts from the Ministry of Transport, the Ministry of Construction and leading experienced units in the field of bridge and road construction in Vietnam, to discuss solutions. method of lifting concrete pillars above the ground.

Rescue operations are still taking place urgently and must ensure absolute safety for the force performing the task.

Although it has been many days since the incident, the press has also published a lot of pictures about the process of rescuing Hao Nam, but many people still ask why the b.oy weighing more than 22kg was born. through a concrete pillar with a diameter of 25cm?

Photos and videos record the scene of saving the b.oy at the beginning, r.evealing the mound with a "death" pit, the crater is about 60-70cm. This is the reason the b.oy 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.

According to the workers present at the scene who participated in saving Hao Nam, when the incident happened, the workers took a lunch break and prepared to eat. And before that, this group of children was reminded when sneaking into the construction site.

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.

As reported by Dan Tri, around 11:30 a.m. on December 31, 2022, Thai Ly Hao Nam (10 years old) and 3 neighbors entered the Roc Sen bridge project located on provincial road 857, Phu Loi commune, Thanh Binh district to pick up iron.
