Chongqing explosion killed 16, and 2-meter boulders were scattered at the scene. How difficult is the rescue at the scene of the story?

The explosion accident in Chongqing is serious, because there are serious casualties and economic losses. The place where the explosion happened was a local canteen. The time of the explosion was around noon 12:00, which was the time for lunch, so many people gathered in the canteen. After the explosion, rescuers arrived at the scene for search and rescue at the first time, but the rescue work was very difficult because the explosion produced a large number of ruins.

The explosion caused several houses to collapse.

According to eyewitness accounts, at about noon 12:00, they heard a loud noise. They thought it was the sound of firecrackers or artificial rainfall, but suddenly they saw a building emitting white smoke and collapsing, and the houses next to it collapsed one after another. The scene turned into a very big ruin, and many people were trapped under it. Moreover, the explosion produced a large number of boulders, and rescuers cannot easily remove these boulders, otherwise it is likely to cause secondary collapse, endangering the lives of people below, and the rescue task is difficult.

Third, the number of people trapped is very large.

The explosion of this canteen is mainly due to the gas leakage in the pipeline, and the influence of gas explosion is very great. Because noon was lunch time, many people ate in the canteen at that time, including some staff in the canteen. After the explosion, they had no time to escape and had to be buried under the rubble. Therefore, the explosion attracted the attention of the government and sent more rescuers.

Third, the geographical location of the canteen is quite special.

This canteen is located on the hillside behind the office building of the street office. Because the streets are crowded, there is no way for vehicles to pass and large rescue equipment to enter. Rescuers can only move those stones with shovels or hands, which aggravates their rescue task. Moreover, they need to support the collapsed floor with wooden boards and use a lot of search and rescue dogs.
