The sequence shows how a massive water seepage transformed the subway passageway into a chaotic scene in a matter of seconds, dragging an excavator and multiple construction materials in its wake.
The escape of workers after flash flooding
Internal images of the project reveal an extremely dangerous situation. Some members of the construction crew were working near the entrance when a column of water began advancing with considerable force toward the interior of the deep deep borehole structure. For example, two of the employees reacted immediately, heading towards the exit area to get to safety.
For his part, the third worker, who was operating a mechanical shovel further inland, was nearly swept away. Although his colleague tried to alert him,
The county government has opened a rigorous investigation to determine the exact origin of the leak. The first technical hypotheses focus on two common factors in this type of works: the
The responsible construction company decided to temporarily suspend all work. This strategic pause will allow the company to carry out evaluations and reinforce protection protocols for the equipment.
The flash flood in the Ningnan Tunnel demonstrates the critical need for improved early warning systems and emergency plans, an essential event to mitigate the inherent dangers of tunnel engineering and prevent such incidents from escalating into major tragedies.
