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

65438+10.7, it was reported that the wall on one side of the container suddenly collapsed in a supermarket in Hongdu, Nanchang, and the scene was a mess. So what caused the sudden closure of such a big supermarket?

First, the house is too old: a large part of houses in China were built in recent decades, especially after the reform of commercial housing, the real estate market has developed rapidly. Theoretically, these houses are generally not long, and their safety performance should be better. But in fact, due to the quality of raw materials, construction technology, construction level, quality control and other issues, some houses built earlier have gradually entered the retirement period and become dangerous buildings.

Second, the foundation is not firm: geological exploration is an important part of housing construction. Tall buildings have risen from the ground? If the foundation is not firm, the greater the possibility that the house will collapse. Take Chenzhou as an example. The underground geological conditions in Chenzhou are very complicated, and it is a typical karst landform. There are many underground caves, rivers and undercurrents. If the exploration is not in place, it is very easy to have various problems such as foundation and piling. In addition, the buried depth, width and depth of the underground river, the thickness and integrity of the upper stratum of the karst cave, the nature of the underground soil layer, the structural type, load, length, width and height of the proposed building, etc. should be considered during the exploration.

3. Altering houses at will: Many house users alter houses at will without fully understanding the structure of houses, resulting in some dangerous consequences. For example, many users now transform the balcony into a kitchen, and pile too many heavy objects on the balcony, which destroys the original stability of the house, so there will be many buildings? From the balcony? Phenomenon. Therefore, Bian Xiao guessed that the collapse of one side of the supermarket was also the result of unauthorized renovation of the house, which destroyed the stability of the house.

The above reasons are some speculations by Bian Xiao for reference only, and the specific reasons need further research.
