The ancient bridge in Sichuan and the Wenchuan earthquake failed to be knocked down and were identified as dangerous bridges by experts. Why didn't the bomb fail to detonate

China, the hometown of bridges, has been called "the country of bridges" since ancient times. Many bridges left by China in ancient times can be regarded as feats in the history of bridges in the world, such as Zhao Zhouqiao. At present, China has cooperation with many countries in infrastructure, and it also has the nickname of "Infrastructure Madman" internationally. It can be seen that the infrastructure level of our experts has won the trust of other countries.

Nothing is absolute, just as all products have a defective rate, not every expert in China has real talent and practical knowledge. There was a "dangerous bridge" in modern times. With its own tortuous experience, it personally staged a "counterfeiting" drama, which was bombed by hundreds of kilograms of blasting bombs and blew up a group of ridiculous pseudo-experts.

"Dangerous Bridge" can't be done without bombing.

Tuojiang Bridge in Jianyang, Sichuan, was built at 1967, widened and rebuilt at 1996, and strengthened in 2006. For decades, this bridge has made an indelible contribution to people's exchanges between old and new cities in jianyang city. Not spectacular enough, not representative in the history of bridge architecture. It is just an ordinary bridge for people to walk every day and give full play to their role. It is worth mentioning that this bridge is particularly strong after widening and strengthening.

In 2008, after the Wenchuan earthquake that shocked China and foreign countries, many high-rise buildings collapsed and many fresh lives passed away. Although the bridge stands on the Tuojiang River, cracks inevitably appear. Sichuan, which has just experienced great changes, must not have any life accidents again. Although reluctant to part with this hard-built bridge, the jianyang city Municipal Government invited experts to appraise it. Some experts have concluded that this is a "dangerous bridge" and must be demolished by blasting immediately.

This bridge is difficult to blast, because it is 690 meters long and is a hyperbolic arch bridge with 17 holes. According to experts' calculations, people decided to use 380 kilograms of blasting bullets for blasting, and thousands of holes were punched in the bridge for assistance. The determination of the experts to tear down the bridge could not be stronger.

This bridge has an extraordinary significance in the hearts of Jianyang people. Its existence promotes people's communication and helps Jianyang develop its local economy. The demolition of this historic bridge is a great event that can be written into the county annals for Jianyang people, so many people come here to witness history. As the explosion resounded through the sky, the dust was rolled up, and the people of Jianyang could not help sighing, but the old bridge was still gone.

"This bridge is very strong."

But when the overwhelming dust dispersed, people were surprised to find that the Tuojiang Bridge still stood there firmly and silently. Although the blasting point is somewhat damaged, the whole bridge body is still intact. Whether misjudging this bridge as a dangerous bridge or blasting, the expert's face really hurts. The name "Strong Bridge" of Jianyang Tuojiang Bridge also spread like wildfire.

People's lives are above everything else. Maybe this bridge is not a dangerous bridge. After a blasting, no one dares to continue to pass on it. Although some people proposed to seriously maintain and save the cost of building the new bridge, the Jianyang government was responsible for the safety of people's lives, but it was still difficult to dismantle the bridge.

The daily communication between the people of the two cities cannot be blocked, and the new Tuojiang Bridge was quickly built by the local government. Whenever driving on this modern new bridge, people will inevitably miss those hard and simple times in the past, and they will not cut corners. Especially compared with another accident that seriously damaged people's lives and safety, people hope that all bridges are "solid bridges"

Tofu bridge

Tuojiang River is one of the famous tributaries of the Yangtze River. Originated in Jianyang, but it also flows through other places. Where there is water, how can there be fewer bridges? In Fenghuang County, Xiangxi Autonomous Prefecture, Hunan Province, there is also a famous bridge called Fenghuang Tuojiang Bridge. It is a large four-span stone arch bridge, 328 meters long, less than half of Tuojiang Bridge in Jianyang, Sichuan, but the investment is more than 10 million yuan.

Fenghuang Tuojiang Bridge is a gift project for the 50th anniversary of Xiangxi Autonomous Prefecture, but it collapsed before it was officially opened to traffic. This happened in 2007, dozens of people were killed and the economic loss was nearly 40 million. Coincidentally, two months before this incident, another Jiujiang Bridge in Guangdong, which was built by the construction party of Fenghuang Tuojiang Bridge, was also knocked down.

In chronological order, we have every reason to guess that the government of jianyang city, Sichuan Province has learned the lessons of these two tofu bridges before being cautious about the treatment of the local Tuojiang Bridge. Unfortunately, the invited experts' knowledge and technology level is not up to standard, which leads to the joke of "strong bridge". Later, this group of experts in Sichuan was really found out and the relevant personnel were also dismissed.

On "Dangerous Bridge"

The times are progressing, but the two bridges completed in 2007 are not as stable as the Jianyang Tuojiang Bridge completed 40 years ago, and even cannot be compared with the latter. Is it because the bridge construction talents in China are not as good as before? Is the equipment not advanced enough? It's that the raw materials are not the original, okay?

No, it's obviously the human heart. It's that the people concerned don't put human life above everything else like previous experts. Even the experts who are not excellent enough in the "Bridge Strong" incident know the value of human life. Even if they make a joke, it's not a big mistake after all. It's better than ignoring dozens of lives. We can't attach too much importance to public facilities closely related to people's daily life. Everyone's life is only once, and the interests of the people are above everything else. This is the bottom line.

Moreover, China has the reputation of "infrastructure fanatic" in the world, and China and many other countries have different degrees of infrastructure cooperation. It is because they believe in the quality of China's infrastructure that they will introduce our experts and technology. If this "weak bridge" incident happens again, what kind of international image will China have in the world? Won't they be afraid to walk on the roads and bridges that China has participated in?

Our predecessors planted trees, while our descendants enjoyed the cool. There are many ancient bridges and mountain roads that have gone through thousands of years and still play an important role in our people's daily life. The bridge building built by modern people can never be completed overnight, and it must stand the test of time and future generations. Otherwise, similar incidents will happen again in the future, and that person will be nailed to the shame column of history by the people.

The "Qiaoqiang" incident hit a group of "pseudo-experts" who cherish human life. Although there are unnecessary economic losses, these "pseudo-experts" are better than those who ignore people's lives and health. To some extent, carelessness is more harmful than incompetence.

Fortunately, this extreme event of "strong bridge" and "weak bridge" is only an example, which is rare in the world and does not happen often. China's infrastructure is still very competitive on the whole. In China, we will never lack a group of real experts like 1967. In the future, as long as we learn from the lessons of history, choose the good ones, follow the good ones, change the bad ones, do things with real skills and behave with conscience, we will not bear the "dangerous bridge" that Sichuan has been unwilling to fall for a long time.
