9 people were trapped when the Guangxi Leye Tunnel collapsed during construction. What impact did the accident have on tunnel construction?

It will delay the construction period of the tunnel and is not conducive to the construction of the tunnel. At that time, there was construction in the Leye Tunnel in Guangxi. While the workers were constructing the tunnel, the rock on the roof suddenly collapsed. Many people accidentally failed to escape, causing nine tunnel workers to be trapped in the tunnel. The police are currently providing emergency treatment to the trapped people. When the rescuers arrived at the scene, they asked other workers and found that the oldest of the nine workers was only 57 years old, and the youngest was only 24 years old.

So we must rescue these workers. When building a tunnel, sometimes a hole is drilled in the mountain, and sometimes the tunnel may collapse. This happens from time to time. Because after all, tunnels and highways are built after the detection of the mountain. If it is not built well and cannot be supported, the tunnel inside the tunnel entrance will collapse, causing considerable casualties, so workers must pay attention when building tunnels.

In the pictures taken by the reporter, we can see that the rock has collapsed on the I-shaped support at the entrance of the tunnel, because there is a rock on the mountain at the top of the tunnel that hits the support, causing the support to collapse A collapse takes place and there is a lot of rubble of various sizes around it. When the employees came to the scene, they conducted life detection on the scene, but no life of the worker was detected after three times. The signs were very dangerous. So far, we don’t know whether the nine people are alive or not, and rescue workers are currently dealing with them urgently.

There are many reasons for tunnel collapse. One of them is that when constructing the tunnel, the direction of crossing the tunnel entrance is wrong. As a result, the water quality and geology do not meet the conditions for tunnel construction, which will cause collapse. Because the conditions are relatively harsh, faults will form when they penetrate the mountain. A moderate collapse will form, and there will be water. If there is a lot of water, the mud on it will be very soft and not enough to build a tunnel.

Every time we travel on the highway, we can find that some cities have many mountains, so mountainous areas cannot be avoided when building roads. We can only build tunnels to pass through, but when building tunnels, certain conditions must be met before they can be built. Because it is penetrating the mountain after all, if it is not detected properly, it will cause a lot of casualties.
