What caused the deck collapse of Changfeng Bridge caused by Wuhan sand truck?

I think there are many reasons for this problem, and I can't express it clearly in hundreds of words here. The most serious reason is nothing more than the bean curd dregs project. Nowadays, many contractors use poor building materials in order to earn a little money, knowing that this material has quality problems, but still insist on using it. This behavior is not as good as that of pigs and dogs. Secondly, most construction workers may have the problem of cutting corners during the construction process. There is no doubt that I have worked on the construction site. Some employees in private enterprises, especially after work, will cope with their work casually. National projects will not.

One of the most important reasons is the serious overload of large trucks, which led to the collapse of the bridge deck. This must be familiar, because it happens all the time. Old drivers who have driven trucks basically know that if they are transported according to national standards, the round-trip fuel fee and high-speed fee will not be earned back.

Second, as the old saying goes, if the bridge is too old, people will be old, but the road will not be old. The second factor leading to ground collapse is that the bridge deck can't bear heavy load because of the long construction time. At present, there are about 6,543.8 billion cars driving on the road every day, which is affordable for that road. Secondly, due to the unstable evaluation of the bridge structure itself, most of them may collapse.

Third, the weather is uncertain. External factors may also affect the bridge collapse. For example, it rains for a long time. Recently, many areas have entered a rainy period, which may lead to the water content of buildings on the bridge arch, thus affecting the overall stability of the bridge structure. If this problem occurs, please stop and get off immediately while driving and find a safe bunker to wait for rescue.
