The first rebel of the Tang Dynasty

Chapter 2148 It's so wonderful

Hearing what Duan Lun said, Li Yin directly vetoed it.

"Widening the road is not feasible, but I have a new way."

"any solution?"

"Build a viaduct! Let the car drive in the sky!"

Viaducts are bridges that can span deep trenches and canyons in place of high embankments, and bridges that span roads in urban bridges, supported by tall supporting towers or pillars.

There are many ways to build it alone.

There are channel girders, plate girders, and box girders.

Each has its advantages.

Of course, there is no best, only more suitable.

"What is the function of this viaduct?" Duan Lun asked at this time.

Li Yin said slowly, "There are three points, listen carefully."

"Yes, sir."

"The first point is to alleviate the traffic pressure in the city. Because the current roads are fixed, it is very difficult to change the width of the road. But if the bridge is built in the sky, the result will be different.

With a viaduct, it can play a very important role in the urban planning landscape.

With it, urban space resources can be used more effectively, so that different vehicles can run smoothly in different road environments. The upper vehicles cannot affect the lower ones, and the lower vehicles, because of the viaduct, can further reduce The conflict between vehicles improves the driving efficiency of vehicles on the road.

At the same time, the construction of viaducts can separate vehicles and pedestrians, which is conducive to reducing mutual interference between vehicles and pedestrians.In this way, for pedestrians, they are safer.

For cars, there is no need to be slowed down because of pedestrians. "

When Duan Lun heard this, he nodded involuntarily.

"About this point, what you said is very correct. With the viaduct, this problem can indeed be solved. What about the second point?"

"As far as Chang'an is concerned, of course, if other places are properly planned before the city is built, there is no need to use viaducts."

"Yes, sir."

"Because of the development of Chang'an City, the cost of land is getting higher and higher. If you simply want to widen the road, you will have to pay more costs, and the results will not be good. It is possible that after paying a lot of costs, What you get is just one more lane, and if you have one more lane, it really has little impact on the feasibility rate. Therefore, secondly, the viaduct can save the land cost of road construction.”

"Yes, sir."

Since the land resources in urban areas are very expensive, building viaducts can save precious land resources to a large extent.Compared with the ground traffic channel, the viaduct occupies a smaller area and makes full use of the vertical space, which can effectively relieve the pressure on the land.

"The third is to change the layout of the city! The viaduct itself has a very important feature, that is, there are few exits, so the viaduct can be used to connect the urban area and the urban functional area, shortening the time distance between the urban area and the urban functional area. In this way, it will drive the rapid development of the city, and at the same time, it can also quickly promote the development and utilization of the peripheral economic zone of the city."

"This is really unexpected, sir."

Regarding this point, Duan Lun said that he did not expect it.

"Fourth, the rise and establishment of the viaduct has changed the living pattern and structure of urban residents to a large extent, which has driven the growth of the urban economy to a certain extent and brought about the improvement of people's material life."

The last point is relatively vague, but it is also a very important point.

"To sum up, the benefits of the viaduct are many.

It can indeed save land cost. Compared with the ground traffic passage, the viaduct occupies a smaller area and makes full use of the vertical space, which can effectively relieve the pressure on the land.

Moreover, it is not affected by urban underground facilities. The construction of viaducts can avoid interference and damage to these underground facilities, protect the integrity of urban underground infrastructure, and reduce construction risks and maintenance costs.

Relatively low economic construction cost.The viaduct has a relatively simple structure, does not require large-scale civil engineering and underground excavation, and has a short construction period, which can greatly reduce the capital investment required for construction.

Moreover, the use space is wide, and the viaduct has a large use space, which can accommodate more traffic flow, improve road traffic capacity, and thus alleviate traffic congestion.

It also improves social benefits. At the same time, the viaduct can also improve the quality of the environment, reduce exhaust emissions caused by vehicle congestion, reduce noise pollution, and improve the quality of life of residents. "

Having said so much, Duan Lun kept nodding his head there.

"Then can Shengtang Group build a viaduct?"

Speaking of the point.

Li Yin's reply was naturally: "Of course."

"How about the construction period? Will it affect our roads?" Duan Lun asked again.

Li Yin replied: "There must be an impact. But if we do it, the impact will be minimal."

"How to do it?"

"Prepare the piers in advance, pour the bridge in blocks, and when the piers are ready, you only need to erect the bridge to complete it, which is faster than repairing a road.

Moreover, the location and time of the impact are not large. "

"How fast?"

"If the road width is 10-20 meters, it will take 2 months to do one kilometer. If it is smaller, it will be about [-] kilometers, usually about three months. If it is very long, it is possible to do it in one or two years. But the viaduct can be constructed in sections, so the time will be shorter. From the perspective of our construction team from Shengtang Group, it can be completed in one kilometer and one month."

Because of the large number of people, the bridge was built before, and it can be assembled directly after the piers are poured. The main reason is that the cement will take a little longer to solidify.

Other installations take a very short time.

This kind of project can only be done by Shengtang Group, and even the imperial court can't do it.

"What about the cost?" Duan Lun asked again.

This must be asked, otherwise it will not work.

"The cost is about half of the road."

When Duan Lun heard this, he was shocked.

It's too cheap, isn't it?
But Li Yin said again: "I can only give you a rough idea. The specifics still depend on the difficulty. The difficulty is different, and the price is different. This has to be considered comprehensively."

"Yes, what you said is very true!" Duan Lun said quickly.

Now he can't wait to go back to the palace and talk to Li Shimin about the viaduct.

"Do you have any other questions?"

"No more, no more, I'll go back and talk to His Majesty now, and see what to do!"

"Go."

"Sir, then I'll go first!"

So Duan Lun left Tanglou and went to Tai Chi Palace.

After going to Taiji Palace, the whole Tang Dynasty is afraid that another change will take place.

This is a good thing, this is another opportunity for Datang.

And Li Shimin is also waiting for Duan Lun's news in the palace.

He also asked the people around him.

"Is Duan Lun back?"

"Your Majesty Shangshu hasn't come back yet."

"Okay, if he comes back, tell me, I want to go and have a rest!"

"Yes, Your Majesty!"

But when Li Shimin was about to turn around to rest, Duan Lun came back in a hurry.

When he saw that Li Shimin was about to leave, he stepped forward quickly.

"His Majesty!"

Li Shimin turned around and saw Duan Lun.

"Why did you come back? It's been so long!"

He said with some dissatisfaction.

Duan Lun has been away for too long.

Li Shimin was very dissatisfied.

"Your Majesty, I'm looking for the sixth prince, and he gave me some advice!"

Duan Lun said so.

"What opinion?"

"One is to restrict vehicles without changing the road, but this minister thinks that it will only affect the economic development of the entire Tang Dynasty, so I won't talk about it. The next thing that minister will talk about is very It’s wonderful, His Majesty must listen.”

Li Shimin frowned, and wanted to say it, but you should say it. If you don't say it, how would I know.

This procrastination, what is it!

"Speak quickly!"

"Yes, that is to build viaducts, viaducts!"

"What?" Li Shimin was shocked.

what is that.

"It means building roads in the air. Just like our bridges." Duan Lun said again.

"Oh, this is amazing!" Li Shimin was attracted.

This way is indeed amazing.

"Yes, Your Majesty!"

"Then tell me, what benefits does it have, if the benefits are not great, then there is no point in building it!"

"Yes, there are mainly five points." Duan Lun himself summed up five points of benefits.

"Say!"

"The first point is that because it is in the air, it can save land costs. This means that there is no need to expand the road, and there is no need to use the already built buildings. Otherwise, how many buildings will be affected by this road.

Moreover, the real estate is so expensive now, the imperial court may not be able to afford such a large fee!The construction of viaducts can also save precious land resources to a large extent.It's like building a subway underground. In this way, our problem will be solved! "

"The first point is that there is indeed enough understanding to build a viaduct."

Li Shimin said.

"The second point, because in the past few years, we have buried a lot of pipes and cables underground. If we build roads on a large scale, it will definitely affect these things, increase risks, and maintenance costs!"

"The third point is that the viaduct is very cheap, which can save a lot of economic construction costs because the structure of the viaduct is relatively simple, does not require large-scale civil engineering and underground excavation, and the construction period is short, which can greatly reduce the capital investment required for construction. "

"How much does that cost?" Li Shimin asked.

"The sixth prince said that it only needs about half of the road, but he didn't say how much, but I believe that the viaduct is better than the road!"

"What about the fourth point?"

"Fourth point, with the viaduct, the traffic capacity of the road can be improved, thereby alleviating traffic congestion. In addition, the viaduct can also provide the city with a variety of functional spaces, such as setting up parks, walking paths, etc., activating urban space and increasing the number of people. places of leisure and entertainment.”

This point, Li Shimin really did not expect.

It can still be like this.

"Fifth, improve social benefits: Viaduct construction can improve urban traffic mobility, reduce the impact of traffic congestion on citizens' lives and economic activities, improve traffic efficiency, and promote economic development. Reducing noise pollution can also improve people's quality of life! "

Li Shimin fell silent.

At this moment, his heart was already in turmoil.

This is what he wants.

Then with the viaduct, the future economy will go to a higher level.

At this moment, his heart was very excited.

But on the surface, he said: "Well, you can talk to him again to see how much money you need, and try to lower the price as much as possible. This is beneficial to the people's livelihood. I believe that this is also a good thing for Shengtang Group. Good thing."

Li Shimin said very shamelessly.

I also want Li Yin to lower the price.

But in fact, it is impossible for Li Yin to surrender.

This is not the first time this has happened.

But Li Shimin still thought that it was possible.

However, at this time, Di Renjie called.

Duan Lun didn't dare to pick it up.

But Li Shimin said: "Whose?"

"It's Di Renjie's call." Duan Lun said.

"catch!"

"Yes!"

So Duan Lun answered the phone.

Di Renjie's voice came from the other end of the phone.

"Duan Lun!"

"What's the matter?"

"How are you doing about the viaduct?"

"Applying with His Majesty!"

"That's fine, you should hurry up and sign the contract as soon as possible, because my husband and I are leaving Chang'an for other places."

Di Renjie said so.

Duan Lun's heart skipped a beat.

"What can we do then?"

"So you have to hurry up, we will set off at night! Otherwise, we may have to wait for ten days and half a month."

Di Renjie said so.

"This... that's good!"

If this is the case, it seems that there is nothing to talk about.

When Duan Lun hung up the phone, he saw Li Shimin.

"Your Majesty, this..."

"Go to him and ask how much it is. If it's really half of the road, just sign it."

Li Shimin said so.

There was nothing he could do.

If Li Yin is allowed to run away, who knows how long it will take for this to start.

And this time it was Di Renjie who was with him, so it was even more interesting.

Therefore, Li Shimin said so.

Let go of Li Shimin.

Duan Lun immediately understood.

"Yes, that minister is going to find the sixth prince!"

"Go, this matter must be fast!"

So Duan Lun left the palace again.

This back and forth made him very tired.

Li Shimin is really good at torturing people.

In fact, Li Yin did not earn much money from the court, it was because they thought it was expensive, and it was because they felt that they had earned their money.

In fact, there is no need for Shengtang Group to make money from them.

This is a fact.

After Duan Lun arrived at Shengtang Group, Li Yin was about to leave.

In the end, it was only under Duan Lun's begging that Li Yin agreed to him to stay.

"What's wrong? What's the problem?"

"Sir, can you sign the contract? Let's settle it. As long as the cost is not more than half of the road, it's fine."

Duan Lun didn't want to talk about it anymore, and there was no need to talk about it.

It's such a waste of time.

Time is wasted, but things are not done well, and it is the common people who are suffering, and it is Datang.

Therefore, he directly asserted himself.

"Okay, I said about half, it must not exceed too much, if it exceeds, Shengtang Group will take care of it!"

"So good!"

"You stay here, I'll let Wei Zheng sign with you, I have to go outside now."

"Yes, sir!"
