Chapter 180: Renovate Sanyuan Bridge in one week?

"Classmates, I know many of you have been to Huaxia, but who knows the name of this bridge?"

There was complete silence for a moment. Although they had been to China, it was still too difficult to ask them to name a bridge.

And there are so many magnificent bridges like this in China!

Who knows which one this is?
Suddenly, a voice guessed: "This seems to be a bridge in the capital, but I forgot what it is called."

Bruce nodded with satisfaction: "Yes, this is the Sanyuan Bridge in the capital. As far as I know, the Chinese government is about to renovate the bridge. Why don't you guess how long it will take?"

As soon as they heard that they had to guess a riddle, everyone became interested.

"Several months, I suppose?"

"Several months, at least several years!"

Everyone talked at once, with all kinds of answers.

Bruce smiled and said, "To help you understand the situation, I will give you a few numbers for reference."

“It took five years to renovate the bridge across the Charles River.”

Of course everyone knows this bridge because it is very close. Standing on this bridge, you can see the Harvard campus.

According to the original plan, the renovation was to be completed within two years.

But two years later, the staff said that another year was needed.

After another year, they said it would take another year and added an additional budget.

It took five years and three times the budget to complete the renovation of the bridge.

You know, there is almost no traffic on this bridge.

It takes five years to build such a small bridge, let alone other bridges.

[Oh, I know that bridge. They said it would be repaired in two years!]

[I didn’t expect it would take five years. The government’s efficiency is ridiculously low! ]

[Every time I pass by, I see construction workers sitting by the bridge drinking beer, not working! ]

【Oh my god, they have no professionalism at all! 】

When Sanyuan Bridge was first designed, the total number of cars in the capital was no more than 160,000.

However, with the rapid economic development, the average daily traffic volume has now reached 200,000 vehicles!

The average daily number of passengers reaches 700,000!
It far exceeds the original design standards!

After several repairs and emergency repairs, Sanyuan Bridge finally could not bear the weight.

Therefore, China decided to renovate and upgrade the Sanyuan Bridge so that it could continue to shoulder its important tasks.

After hearing the data given by Bruce, the students gave their own answers.

Most people guess that it will take more than three years to complete.

Although China's infrastructure level is slightly better than that of the United States, this is a bridge with an average daily traffic volume of 200,000!

Not the little bridge over the Charles River!
Three years is considered too short. It would be great if we can complete it in five years!
Bruce smiled slightly: "I can tell you that the time given by the Chinese authorities is one week."

[Renovating a bridge with an average daily traffic volume of 200,000 people in one week? You must be kidding! ]

[Walter? This is impossible, right?]

[What can you do in a week? The Chinese are too arrogant! ]

[I admit that China's infrastructure is impressive, but this is too exaggerated.]

[For a bridge of this size, it would take a week just to measure it, right?] [I am a bridge engineer, and I can tell you clearly that a bridge of this size would take at least three months to renovate!]

On the other side, Anna was equally surprised: "One, one week? Honey, did I hear it right?"

It only takes a week to renovate such a wide bridge?

This is simply impossible, right?
Chen Lu nodded: "The official time given is indeed one week, and based on past experience, this week is the longest time. The actual construction time should not take a week."

The foreigners couldn't believe it. It was really a bit unbelievable that a week was enough.

The reason why Huaxia wanted to shorten the construction time was because this bridge is an important transportation hub in the capital and the eastern gate of the Capital Airport.

The traffic volume is extremely huge, and if the renovation is not completed in one day, it will cause huge economic losses.

So we have to race against time.

After discussion, the engineers decided to adopt the method of overall replacement of the bridge, prefabricating the new beams in the beam yard and then transporting them to the site for direct assembly, which greatly improved efficiency.

In front of everyone's eyes, the renovation of Sanyuan Bridge officially began!
"One-two-one! One-two-one!"

Shouting uniform slogans, hundreds of workers moved together!
The movements are highly uniform, as if they were carved from the same mold!
"One, two, get up!"

With the cooperation of several workers, something weighing hundreds of kilograms was actually lifted up!

They gritted their teeth, worked closely together, shouted slogans, and placed the heavy objects on their bodies to the designated location.

[Walter? They finished the measurement so quickly?]

[This strength is too great, it's so easy to lift it up! ]

[Why do these people look so thin but have so much strength? ]

[I don’t think it’s because of how strong they are, but because they work together very well! ]

[You are right. You can see that their steps are completely consistent and their slogans are also highly unified. It is as if they were cast from the same mold! ]

[It is impossible to do this without hundreds of times of practice. It is really shocking! ]

[China's infrastructure level not only relies on high technology, but also relies on these tacit construction workers! ]

Moreover, the division of labor is very clear and orderly, and everyone contributes to his or her own position.

At the same time, various machines such as cranes also joined the team, using their long arms to lift heavy objects.

The workers cooperated with each other, working in groups of several, and cooperated seamlessly, and quickly moved all the things to the designated location.

They did not resort to blasting, but rather to a combination of machines and workers.

In fact, blasting is more convenient, but it will cause pollution. More importantly, it takes a lot of time to clean up the garbage.

This traditional disassembly method requires extremely high quality and work ability of workers!

[I see, they are going to replace the entire bridge! If that is the case, it is indeed possible to complete the renovation in a very short time!]

[Engineer, what is bridge replacement? Please explain it to us! ]

[The so-called overall replacement of the bridge means building a new bridge in advance and then putting the overall structure on it, but this method is very difficult! Once there is a slight deviation in positioning, it may cause the bridge to collapse! ]

[It is unbelievable that China would choose such a difficult construction plan? Is it really that speed is the only thing that matters, not quality? ]

The engineer shook his head, as if he could already see China's failure.

The overall replacement of the bridge is too difficult.

If it's a small bridge, maybe you can give it a try.
