A supermarket in Nanchang, Jiangxi suddenly collapsed. Why is there such an unexpected situation?

Judging from the monitoring screen at the scene, it may be caused by external impact. The biggest possibility is that the car hit the wall, and this wall is a load-bearing wall, which eventually led to the sudden collapse of this supermarket.

If it wasn't for the monitoring acceleration I saw, it can be clearly seen from the video that the wall suddenly collapsed after being hit by a foreign body. According to my personal experience, I have been to the blasting site and the scene where the house was washed away by the flood. If the house collapsed because of quality or other reasons, it should not be so violent. From the key collapsed walls in the video, we can see that this collapse came from an accident, not a process. Moreover, judging from the broken fragments of the wall, the wall is still very strong. Without the impact of foreign objects, the collapse should not be like this.

Moreover, it can be clearly seen from the surveillance video that people were injured when the supermarket collapsed. The video shows that a customer closest to the wall is likely to be buried below. Judging from the appearance of the supermarket, this building is in disrepair. Judging from the collapsed style, this building should be an old-fashioned building. Although the foundation of this building has been laid, the overall structure is not designed by professionals. In addition, it is normal for it to collapse when it encounters a little external force. In the early years, it was also common to cast the floor with cement in Gai Lou, and the building structure of the supermarket seemed to be designed by non-professionals.

According to the news report of Grand Prize Network, this supermarket is located in Hongdu District, Nanchang, and its name is Wang Zhongwang Supermarket. At that time, the wall of the container suddenly collapsed, as if it had been pushed down from the outside by a great force. It is said that some customers were crushed under the fallen wall fragments. At that time, when the reporter went to the scene for an interview, he found that a large excavation equipment was cleaning up the scene. According to the network news, 1 person has been killed and 1 person has been injured this time, specifically.

However, from the pictures outside the scene, after the wall was hit, the whole floor lost its support and then collapsed in a large area. It can be clearly seen from the joint gap between the undamaged building nearby and the building where the supermarket is located, as well as the fracture trace of the floor, that this building belongs to the old-fashioned cast-plate building. Many people on the Internet say that there is something wrong with the construction quality of this building, which is the main cause of the accident, but in my opinion, this is not necessarily the case. Although the construction quality of this building is indeed poor, a wall collapse will not cause such a large area of collapse. The most likely reason is that something hit the wall and caused a chain reaction. The last possibility is a car accident, which has happened many times all over the country. Some serious accidents directly drove the car in, knocked the buildings into a pair, and even drove the car to someone else's roof. But this is my own guess, and everything still depends on official reports.
