A bridge under construction in Shaoxing collapsed, causing no casualties. What is the main reason for the collapse?

A bridge under construction in Shaoxing, Zhejiang Province collapsed, but fortunately there were no casualties. At present, the follow-up work of the bridge is under way, and the cause of the accident and the evidence collection work are also being carried out in an orderly manner.

According to official reports, the cause of the bridge collapse is still under investigation. The video shows that some collapsed bridges have been submerged in the water, and the scene is shocking! Moreover, the accident has been entrusted to a third party for inspection and testing, and there should be a fair judgment and statement. We just need to wait for the official results.

But before that, we can also boldly imagine the possibility of bridge collapse:

1. The design of this bridge itself is unreasonable.

In the design process, there are unreasonable factors in the bridge, which are easy to cause collapse. According to its introduction, the total length of this bridge in Shaoxing, Zhejiang Province is about 28 kilometers, and the collapsed part happens to be the Zhongshui section.

According to the design drawing, the arch bridge was originally designed on this section, but I don't know what caused the bridge to bear the pressure. But in my opinion, this accident is also "lucky" from another angle. Fortunately, no casualties were caused, and fortunately, it was not officially opened to traffic, otherwise the consequences would be really unimaginable.

Cut corners

Cutting corners is one of the taboos, but in real life, bridge collapse accidents caused by cutting corners occur from time to time.

The Xiaojianshan Bridge in Kaiyang County is one of them. Eight people were killed and 12 people were injured in this tragedy. The reason of this accident is that the wall thickness of some supporting steel pipes is not enough, and there is a lack of pad between the main pipe and the sleeper, which does not meet the relevant design requirements.

Although we often talk about "safety first", in fact, some teams or leaders still forget the word "safety" and blindly seek benefits and save costs, which eventually leads to tragedy.

overburden

The damage of vehicle overload to bridges and highways is also quite serious, and there are potential safety hazards. If the overload is serious, it is likely to lead to tragedy.

For example, a rollover accident occurred on a viaduct in Wuxi City, Jiangxi Province, causing three cars to be crushed. After investigating the cause of the accident, the truck was overloaded. Of course, this bridge collapse in Shaoxing, Zhejiang Province can rule out this possibility.

4. Human error leads to tragedy

Perhaps in the eyes of most people, the bridge is so huge that even if a screw is dropped, it will be fine, but in fact, on the contrary, it is very likely that a screw will destroy a bridge.

This is the case with a bridge in Xiamen, Fujian. The cause of the accident was that the construction workers disobeyed the command and removed the steel bars under the bridge without authorization, which led to a tragedy. So any operation may lead to serious consequences.

Looking at the bridge collapse accident in Shaoxing, Zhejiang Province, I personally think that other reasons are possible except the third point. Of course, this is just speculation, and the details have to wait for the official announcement.

However, these cases also remind us that the stability and safety of bridges are related to everyone's personal and property safety and must not be taken lightly. It is hoped that the relevant departments will strictly investigate the cause of the accident, and the contractor can learn a lesson to avoid similar accidents from happening again.

Write to the end

In fact, not only the safety of bridges, but also traffic accidents, fires and other security risks remind us that no matter what industry we are engaged in or what environment we are in, we should put safety first.
